Here it is: The BANSHEE DIRTBIKE

[hawaiirider]

im putting a banshee motor in a crf450r frame, actually its pretty much done now. BUT, a prob popped up: im using the 450's radiators and the banshee motor has a hose coming out of the head (the small one in the middle of the spark plugs) that has no place to go on the new radiators? also i have no idea where the darn skinny hose coming out of the waterpump goes either? any help is appreciated!!!! one last if you will the rear brakes on the 450 lost prime after they were disconnected, i tried the conventional method of primeing it, no luck?:confused:

[SYKO]

cant help you any... but you need to post pics ASAP!

[cr480r]

the hose on the head goes back to the radiator tank to let air out of the system.. not sure about the other hose its been awhile since i had a banshee apart.. If i remember correctly it isnt part of the cooling system.. I have always wanted to build a banshee powered dirtbike.. Have any pics of this thing? I am curious of what you use for exhaust

[RoscoW]

I think the hose from the water pump area is a crankcase vent and it hooks up with a "T" to the vent on the back of the motor in the depression.

Ross..

[factoryX]

I have question, why was this moved to the quad forum? is this not a dirt bike or a trike conversion? talk about getting sloppy..

[hawaiirider]

any idea what to do with the hose? it spews alot of water out constantly, i can hook it to the overflow but that stays shut until the bike over heats? im almost stumped

this is all I could find. also pics would be helpful.

[hawaiirider]

thanx it all came togerther today, its maiden voyage is tomorrow ill post pics soon in the bike section i guess.

[hawaiirider]

was alot harder to build then planned, but its rideable now. Its no KX500 but its a unique bike that WILL climb just about any hill here in hawaii. The only thing i need to finish is the pipes, they suck hanging out of the frame! it was alot of welding just to get to this point w them, i need another pair to work on, some different carbs too, the ones i got are hammered. enjoy. :beer

[factoryX]

I like it, but pictures are on the little side though..

[cr480r]

bigger pics please..

[300rman]

X2 on the bigger pics.

sweet idea!

[trimoto.125]

Also need to see bigger and more pics. This looks like a very unique build. Can;t wait to see a vid.

[300rman]

More Pics and an UPDATE!!!!! RIDE REPORT!

[hawaiirider]

working on pics, only have the cellphone camera spent all my $ on some new carbs none left for a digital camera but that should solve the only running on 1 cylinderr prob i had yesterday. Still ran the toughest trails out here stay tuned ill post a vid later...

Borrow a friends digi-cam!


cant wait for some good sized, close up pics of the project, this is extremely cool!



is it a beast?

[SAVAGE420]

Yeah, pics or GTFO bro!!!

[factoryX]

any pics yet?

[300rman]

any pics yet?

I know!!! im dying for some close-ups of this project, and want to hear a ride report!

[hawaiirider]

ill be riding it all day today and tomorrow so ill post pics late monday hawaii time.

heres the link
please let me know if you have an old or extra set of pipes youd part with as i need to start welding a pair while i continue to ride.

[Rm250RF900R]

that is pretty damn cool. nice work.

[300rman]

well? how is it? beasty as hell?

if not, serious power isnt too far away......you could make that thing 80 horses

[hawaiirider]

its good on power, just jetted too rich no biggie, im gonna ride it for a while before any work is done to it again.

[300rman]

How about some close up pics, and maybe a rundown on some of the bug hurdles that had to be Overcome while doing this?

[hawaiirider]

this site is too picky about pic size so i cant help ya there. all i can tell you is putting a parrallel twin in a skinny dirtbike frame is not going to be easy or cheap without the right resources, im lucky im in the service and saved huge$ through readily available material.

[Kerick]

looks sick and really fast...i love that spot your riding...Where is it?

[Dirtcrasher]

Just spend 5 minutes and open a FREE Photobucket account, copy and paste the IMG code here and you have instant huge pictures!!

Cmon bro, this is a build done by very few people and needs to be shared :D

[MagicJames]

If you're willing to put in the work, there's a set of Paul Turner pipes on eBay right now for a buck that have the exhaust bracket broken off and there's a hole in the pipe but if you are willing to put in the effort I know those pipes rock balls. Hopefully this helps

[300rman]

hey, not to dis you or anything, but you need to complete that frame. where the downtube comes down from the steering neck and connects to the cradle......well, it doesnt appear to be connected anymore.

your frame spars WILL snap if you dont deal with that. This failure resulted from a poor weld that connects that steering neck to the cradle. if a weld broke, then the frame snapped, you can bet your ass that no connection at all is a accident waiting to happen.

^Whoa....I'd be heeding that advice.

[hawaiirider]

huh? its not only connected, its reinforced as well, im just that good man!!!!!!! this bike is solid i have tested it to the max and will continue to ride it the rest og the time im stationed out here with minimal changes.

[Dirtcrasher]

Well, the pics/vids are crummy at best. Maybe he "thought' he saw something??

I didn't read everything, but that one pics does make it look as if the main downtube is GONEZO, CYA, BYE!! :D

[Racerguy381]

My buddy is building a one alot like this. Been working on it since this winter not quite done yet but I will have him shoot me some pics. Its a 1998 CR250 frame with a custom aluminum cradle to hold the motor into the frame. :beer

[factoryX]

Umm.. no Not really..:rolleyes:

well it could be...

[300rman]

hey, for a first run, i think its awesome. some better fabbed pipes, completion of the frame, and a run-through, and it will be sweet. and since its one of the first of its kind, he had to do it all himself, no other build threads to follow.

[hawaiirider]

? if you guys rode with me youd change your minds quick, the thing works good, and the frame is a masterpeice one guy couldnt even tell it was connected! the pipes are NOT done of course but like i said it still works good and im sure there will be more guys to build one after seeing it, but this one is built right the first time and it was not an easy build. if you want true advice out of my build ill say -yamaha didnt make this bike for a reason.....

hey, major props for the project. as long as that downtube IS connected, then your golden. the rest is just cosmetics and finishing touches. after you get a good set of pipes fabbed up, you should have them coated, that will really set it off. then just clean up cable routing and misc. stuff like that, and it will make meticulous bike owners drool.

and as for power, a lot of things can be done to lay down over double the power without major work.

[300rman]

oh BTW, any chance for a close-up pic of the downtube section? i am very interested in that.

it was called a RD 350

[300rman]

it was called a RD 350

its still made, but its a streetbike. still made and sold overseas.

[hawaiirider]

didnt mean it like that, i just meant a twin cylinder engine is wider any way you put it and you will have to adjust your riding style.
As for the rd 350 im well aware of it, check my last build if you want, its dam near perfect on the street.

[factoryX]

it was called a RD 350

I thought it was the rz350.

The rz was liquid and the rd was air cooled.

[hawaiirider]

heres last weekends vids, theres a few they are all poor quality but show the bike has super power for the insane hawaiian terrain.

i like it. you get the new pipes made up?

[hawaiirider]

no, im going to just ride it as is until i leave hawaii and then chop it down as a winter project on the mainland.

[hawaiirider]

anybody want to trade this new trinity stage 4 c/v carb and intake for a set of small duals? it rips and cost me 500 clams but i just cant clear the shock with it.
www.trinityracing.com

[Yamahondaman]

The rz was liquid and the rd was air cooled.

I Had several of the RD 250-350-400's back in the day .. the 250-350's were no faster than the TRI-Z but the 400 was Much Faster .. i used to use the clutch and spar gear from the 250 and install it in the 350 .. better Rev Power thru the gears in 200-300 ft. , I installed a RZ-350 motor in the banshee frame and it was slower than the stock banshee motor...

[300rman]

I installed a RZ-350 motor in the banshee frame and it was slower than the stock banshee motor...

the newer ones supposedly keep up with GSXR 700's.


but, the older RZ motors have the same upgrade options the Shee motors have.

[Yamahondaman]

upgrade's yes .. makes a diff for sure like the Cheetah Cyl's on the Banshee..
stock for stock is what i was talk'n bout.. somthen bout the ATV Gearing Versus the Street Gearing matter's MUCHO when you want FAST Power in 300 ft.
iv'e allway's have wanted to GIT My hand's on the TZ-750 2-Cycle ...
maybe beat THAT THING that was at TF07 that shouldn't have been there Racing us 250's

anybody got input on a stroker crank? reliability is key

[RedRider_AK]

Stroker puts more stress on your rod and pin bearings. Take from that info what you will.

[300rman]

Stroker puts more stress on your rod and pin bearings. Take from that info what you will.


your best bet for Banshee info is to get on Everything2stroke.com

[hawaiirider]

yea i asked those guys, there pro's for sure. they seem to think theres more stress on the piston from the longer rod.

[300rman]

yea i asked those guys, there pro's for sure. they seem to think theres more stress on the piston from the longer rod.

no, the stress comes from the more extreme rod angles due to the greater stroke. but i dont think a 4mm stroked motor would create too much of a reliability issue.

get some good pipes fabbed up, pipes are everything on those Shee motors, then worry about other stuff for added power.

[hawaiirider]

took the bike for a ride in the dunes today, the thing is sick in sand!!! absolutley screams!! left my buddy covered in sand:lol:

I cant rid the two pipes, its the seller of its uniqeness. plus it sounds ridiculous. ive had more compliments on the sound of it, you can here howling through the mountainous jungle out here from along ways off.
i have the single carb kit, its awesome, but its too close to the shock if you saw my post about it earlier.

[factoryX]

I must have missed that part. how heavy is this bike?

damn. but hey, as long as your not wanting to MX it, the weight shouldnt be too much of an issue.

[hawaiirider]

yea just sucks when you have to pick it up, or dont make it up a hillclimb- which isnt too often on this thing!!!

[hawaiirider]

still got the same problem going with the rear brake pedal. the engine is so wide that the brake pedal has to stick out far to compensate, leaving it vunerable to the rocks ouut here, ive snapped it off 6 times now even using brake snakes!! i saw they have a left side rear hand brake or thumb brake? opinions? seems like as much clutching you do on tight trailss you wouldnt be able to use it on the left? i dont want to spend 300$ on these if they suck!!

[300rman]

never used one. take a pic of the area in question, maybe we can come up with something different.

so your going from nice warm weather to freezing ass cold? man thats gonna take some adjustment

haha "us 250's"

YAH RIGHT RONNIE! :lol:
thats right!!

[199cr125199]

hey you should make the bike into a fat paddle it would be tight

[hawaiirider]

i just got it up here to alaska. its pretty useless here now, its lots of snow so im rebuilding the entire bike its got low compression and the plastics are hammered from hillclimbing hawaii. the only conversion its gettin is to a 3wheeler next winter which would be more useful than a bike here.

anybody interested in tradin my stage 4 carb kit for some 28mm duals?

[300rman]

have you ever ridden a CR500? how does this beast compare?

[hawaiirider]

heck ya!! i had a 03 kx 500 for years before i built this bike not a cr500 but comparable. the kx has waay more torque, it had a powervalve and would muscle its way up anything, if you didnt make a hillclimb on a kx500 it was your fault!!
the banshee bike is just as fast or even faster on flat pavement but the kx can pass it no problem at all on a uphill, its just a bigger more modern style motor than the nonpower valved banshee, if you want ultimate power the kx is it!!

[300rman]

I bet if you put a grand into that shee motor, the tables would turn. the KX/CR will always have more low end torque than the shee motor, but the shee can have more power when built properly. 90HP shee motors arent uncommon.....

[hawaiirider]

true, 50hp is quite enough in a bike for me tho...

[300rman]

shee motors make around 32 HP stock. pipes and other simple stuff can easily double that, but the question is do the pipes you have make the motor run better than a stock shee pipe would run?

[hawaiirider]

ill let you know, im putting twin 28mm pwk carbs on it cuz my trinity single was too close to the shock. the bills pipes made it run great but the pipes were literally hanging out of the frame. these 125 pipes i got have good low and top with the mid being flat so far...

[dirtjunkie85]

that is totally sick hope you get some more picks up soon

[nitrometh king]

If you don't mind me askin would it be reasonable to put a banshee motor in a tri-z? Or is it too much work?

[jessearends]

i think that would be pretty awesome, if you have the time, equipment, $$$, a banshee, and a tri-z, then why not give it a shot, ppl put some crazy motors in thier tri-z's

[dcreel]

jeddy on the site has built one. I've seen it run.

http://i176.photobucket.com/albums/w182/dcreel/014-1.jpg

[volfan537240]

the main problem with putting a shee motor in a tri-z frame would be the frame modifications where the 2 pipes come out of the motor.

[hawaiirider]

used the bike all summer, now that its winter im fixin up loose ends, its pretty much done, oh and its street legal!

[Afrothunderkat]

you must be a little crazzy man. im sure a 350 twin makes more than 32hp stock. my RM250 has 48 stock.... and you CAN NOT double HP with a pipe and other simple stuff.

[300rman]

you must be a little crazzy man. im sure a 350 twin makes more than 32hp stock. my RM250 has 48 stock.... and you CAN NOT double HP with a pipe and other simple stuff.

look up stock specs for the banshee. They left the factory in a state of serious detune. Most things leave the factory tuned to the max...not the banshee. Getting double the HP out of the Banshee motor is relatively simple, and doesnt require stroker/big bore options to do it.
