Nevermind that dumb question! Guess its time to go to bed haha. :drool:

[oldsking86]

oh yea another one!! what a way to make these old 350x's even better

[NINJA]

sweet setup man, i first saw that motor in a 350x at the Gleason ice races in WI a couple years ago, works great in the non studded class

[super90]

Is that a 200x frame??? It dosent look like a 350x frame for some reason

[Huffa]

Nice project Brapp but the thing looks like it was already ridden or :crazy: your the type guy that doesn't mind working on parts that are dirty ?

Just getting on ya a little :lol: and know that thing will look really nice when done, you are going to wash it, right ? :wondering

Where's the radiators?







Welcome to the 450 club!:welcome:

Where's the radiators?



I believe he is going to weld nuts onto the frame so it can be setup like a 250r, beside the air scoops. Oil cooler is going up below the headlight.

[chris200x]

Josh, what kind of motor work was done to that motor?

[brapp]

if you look close the rads are there but thier off of a 250rin the usuaal location. and th emotor is a esr520 big bore with a sparks agressive cam and a bored out stock carb and a bills thunder series exaust. it dynoed liek 66horse on mr8race fuel

[Derrick Adams]

I see the radiators now that you say that. Awesome Job! I would like to see some close up pics of how you wedged the carb in it. I know on our two conversions it was TIGHT!

[fastleo]

i think i just wet my self... that bike could sure eat some trails up


kool conversion

[Jason Hall]

66 HP on a stock 350X swinger should be FUN. Nice work, looks like a 04-05 TRX engine? You must have a newer style stock carb on there If It's bored. Did you have fun putting that HUGE harness on It also? Thats the part I remember most about doing my 350x/450r.

[sandpuppi101]

Glad too see you got something done with that 450 motor.I've been waiting too see what you were goona do.I'd like too see alot more closeup pic's ,of the exhaust set-up and the cradle when you get a chance..Congrat's ,look's tite !!

[brapp]

well for the moment i still ahve to go trough it and fix a bunch of small quirks but as far as the airbox/carb set up i cut the shock mount and l moved the entire tube back abotu an inch and 1/2 and lowere dit 3/4 of an inch for clearance. and the carb i have on it is of fthe crf dirtbike i belive i am not 100% sure. and as far as the cradle i just cut and tweaked a few parts and made it slightly diffrent . i am thinkign abotu welding a solid piece of 1/4 inch steel plate on the entire bottom to hold it alltogether better. and just cuttign holes in it for the oil plug and the oil cooler lines. but it is still far from complete. but this is just the progress thus far. i may end up using a 450r swinger in the future but thats a little ways off yet. and i do belive i have to shim the valves and i can freshen up the motor also. like i said its a ways from beign done. this is mor eor les sthe fab stage.

[BigGreenMachine]

66hp, damn. Nice!

[Mosh]

Sweet.I may have to build one of these fo-fiddy trikes myself soon.

[BigGreenMachine]

Same. Just not convinced about the fourstrokes yet. Really need some more seat time on one.

[Mosh]

They got sack.alot of it.
The only thing that concerns me is the reliability of these new four strokes.When they blow,Get your wallet out,and a friends wallet,etc etc.

[BigGreenMachine]

Definately have balls but I don't want to build a 66hp timebomb.

[brapp]

lol
this seems more sane than a gsxr1100 powered lt500 lol

[brapp]

some updates comeign soon the oil cooler is mounted the hoses need to be made and the rads are mounted willdefinitly need a swinger made but this willahve to do for the meantime. and also need a shifter made for it
