mini racer thread...60 and 80cc pingers...who knows what and who has what?

[ironchop]

my son and I have an idea.....

so watching that AMA National vid Billy and Keith just put up got me to thinking about the 2 stroke minis and the CR80 trike Hall? raced at TF.

We have some questions:

1) what frame/forks did they use back then?.....dirtbike?.....full custom?....another atc platform?
2) class rules?
3) did anyone here run one then or now? If so, what`s your setup?
4) PICS PICS PICS ?
5) why aren`t they more popular? 80CC dirtbikes around here go for $600-800 running and riding on average and I found a small stash of CR60`s a couple months ago.

it would be sweet if there were enough to run a mini suspended class at TF for 85cc and under.....we are considering building a couple (because 'cool' and cheap)
but for now it`s just in the idea stage.

experiences? thoughts? comments?

Not many 2 stroke minis. The bigger classes would let twice the displacement 4 strokes run against the 2 strokes at one time, before they seperated the classes. You could probably do that with a mini class, but not many suspended minis around. I have 2 and blue27 has one, but all 4 strokes. There are maybe 4 2 stroke minis that I know of, unless others have built custom framed minis. I so could do a Tiger 80 if I found one for sale though.

[the great gazoo]

If only you still had that KTM80 Pat. That's one bike you let go that just didn't make sense.

[MIK6]

I have my miniT3 too!!

[3 Wheel Drive]

I've got 2 yt60s with the Molassi 70cc big bore kits, DG pipes and boyseen reeds. I'm not sure how the zingers would do against the suspended conversion 2 strokes? But they are a lot of fun, my zingers cost around 150 each before upgrades. Someone was selling a mini in the classifieds a while back...

[Daddio]

My son transplanted a pw80 engine into an atc70 frame. It will be a flat tracker only machine. He sent the engine to a good friend of his and had it worked over a little. He also put a PVL ignition on it and is about finished with the exhaust. It should be out on the track in the next few weeks.

yeah initially this would have been a little discouraging but seeing how that 80 or 85cc trike did in the midsize suspended class at TF this year against the 200`s, I see it has no problems keeping up ;). I`m not averse to running one in that class as well.

I can`t recall who that was with that Lil Smoker.......Jacob Hall?

my son and I thought it would be cool to build one. I have a CR125 motor packed away too that ain`t exactly a mini but it used to haul my giant ass around real easy and would make a good trike mill.

Making a motor fit , lineup, and work is cake work for me....what I would really like to know is what chassis to use. Originally, we thought first gen 200X because it was small and suspended but that chassis ain`t exactly the cutting edge in the performance suspension department even by 1985 standards.

[ironchop]

I have my miniT3 too!!

you have a link or pics? I`d be interested in seeing that for sure

[C.J]

I've been working on converting my 82 CR125 over. Tri-Z forks/triples are a direct swap, just have to swap the lower stem bearing. Steering stops even work and the triples don't smash the rads!

[MIK6]

Just use search.. miniT3.. a few posts and pictures come up of mine..

[fabiodriven]

Dude in Europe has a nice mini Tecate. loilz or something like that?

[DohcBikes]

I know it doesnt count but ill be doing a hopped up 50cc four stroke suspended for my nephew. Baja 50cc minibike to start with.

[Jason Hall]

I built the 85cc bike that my son Jacob rode in Mid Suspended at TF. It started as a 86 Atc250r frame. It was not easy to build because I wanted it to look like it was a true 80cc 3 wheeler. Ben Meyer built a really nice 80 using a Suzuki dirtbike frame. His has great ground clearance, and looks like it worked out great with the bike frame. His probably took half the time to build as my 80. We also have a CR60 powered 3 wheeler that I built for Jacob when he was about 7 years old. If you search CR60 Zinger the little 60 should come up.

[zepol]

Would a 2 stroke suzuki alt50 count lol

[1upfront]

Here's my 80cc 2stroke flattrack bike I've been putting together. Its almost done at this point.

[BigBossJake]

Here are a couple pictures of my tecate 60 kx 60 conversion. I thought there would be a few other mini racers! I sold a nice yz 80 conversion a few years back and have always regretted it.

[fabiodriven]

Not to gripe here (but apparently I will anyways), but the title of this thread does say pingers. I'm kinda disappointed this turned into a 70 thread as I'm extremely interested in mini pingers but couldn't give less of a shite about ATC 70's.

[Vealmonkey]

Gripe all you want, but the thread title sort of locked down the thread. I haven't seen one trizinger listed though and I do remember years back there was a full suspension tri zinger that was posted. There wasn't many 60 or 80cc aftermarket frames though which I commented on that at the beginning. I do truly wish there was more available, trust me.

[BigBossJake]

I was hoping for more 2 stroke action as well. The only 2 stroke is mine.

[New2Tri-Z]

All trikes listed except Veals are 2 stroke??:wondering Not sure what you mean. I really like that 70 with the Yamaha 80cc PW motor. But both of the trikes Jason Hall built look awesome. I have never seen the one Ben built, but the one 86T3 had for sale a while back was pretty Cool, little RM80 conversion. Maybe the same trike Im not sure?

Then why not use the search function to help further the discussion by posting threads?

Here you go Ironchop, I found these with a simple "kx60" search. There is probably more by searching for kx80 and some other stupid thread titles. Sadly some pics are no longer available from EBAY auctions or otherwise.

It would seem to me to be good practice to copy the pics from EBAY auctions etc, and have them hosted on 3WW for posterity.

I revoke my previous post. I was watching this thread from the beginning and going by memory I thought there were a bunch of 70's posted. Upon review of the play I call foul. Poster of post #18 is penalized 20 minutes of view time and must shut the fawk up for now.

[bkm]

I'm not a fan of the atc 70's at all, but the pw80 swapped 70 is cool as get out. Now the kx conversions are on a whole new level of coolness.

Yeah I did a few searches back when I first posted this thread but there are a couple you have listed I didn`t see..... so, thanks for that.

I just haven`t came back to this thread until I did some research first

After reading my words, I now take the self imposed fabio penalty......I did not mean to imply you were not able to search, or did not search. I found most of these when I got the kx60 trike converted to a quad which I traded for an A+ ATC.

No offense taken whatsoever....I knew what you meant and I appreciated the effort you put into the reply....that's honest truth.

Yep, same trike. Brian Ditch owns it now

[just ben]

The rm I converted probably took an 1/8 of the time to build compared to your 85 Jason. I am in the process of doing a couple more so that would be 2 more for a class but we would have to up the cc limit a little bit. I have also had a couple requests to build bikes for other people so I think there might be enough for A class by next year.

[ironchop]

..... but we would have to up the cc limit a little bit.....

please explain.

I thought maybe a 125 would be a sweet project as well.

[1upfront]

heres a short clip of my 70 running after the 2stroke conversion, this thing is fearce.

[just ben]

I think a 125 would be cool too but then it would more than likely just be a full size bike with a small engine. The 2 I am working on now are based off kx 100's

[ironchop]

I agree with not wanting a full size chassis with a little engine.

I looked into the KX100 and Im interested as well. I think it makes a great intermediate size trike that I could fit on at least halfway decent. I assume you are using the kx front frame loop as well and adding trike triples and swinger, Ben?

[MIK6]

I have let quite a few board members ride my miniT3. Its cool as hell to watch the smile they have when they get off it!
it is the 2nd hardest reving 2 stroke that I own. You think your about to shift cause of the size of it then all of a sudden it gets up on the pipe and takes off! Its an absolute blast to ride!
think it might have to make its way back to indianna, to TF15!

[bkm]

Ben, what do you think of a kx100 in a first gen frame. They both use the single down tube with the angled exhaust, or is it just too small of an engine for the size of the bike?

[just ben]

Ben, what do you think of a kx100 in a first gen frame. They both use the single down tube with the angled exhaust, or is it just too small of an engine for the size of the bike?
interesting thought but the engine would too far back in the frame for the exhaust to go around the down tube and would need a completely custom pipe. I am having the same issue with another project, the plan was to put a 1st gen kxt 200 engine in a 2nd gen frame. I have the frame done for the swap but now I need a big $$$ custom pipe to finish it. Here one of the 100's Ive been working on 198707

Here one of the 100's Ive been working on 198707I'm always thinking up what I think are great idea's that die as quickly as they were dreamt up, as soon as I get to the exhaust part. I wish I knew how to make my own exhaust. The kx100 looks cool and I like the second gen aluminum swinger.

[Stephon_xr500]

Well I too got to thinking after watching the video of that race in Miami, I have been thinking of making a smaller full suspension trike for my boys... they love to ride the 125cc pit trike we have.


198759

Well I saw this little gem on Craigslist today and talk it down a little. It's not running cause the side case needs to be welded

198761

198762

I have access to some 200x parts... I think it's gonna be great!

[just ben]

That little husky would be pretty cool in trike form. I cant think of anything from a 200x that would be very useful though. The swingarm wouldn't allow for any chain adjustment and the triples are raked and wouldn't work well on a bike frame. I have to pull the engine on one of the 100's for a rebuild BKM,when I do I can set it in a 1st gen. frame to see if I'm right about it being too far back. It may be back far enough for the pipe to clear on the inside of the downtube.

[Stephon_xr500]

The 200x swinger will be to wide I noticed last night. I think i can weld a carrier from a 110 to the end of the current swinger. I'll figure out a triple tree. Good news is the little husky has no shifting and kicks forward to start.

[C.J]

This is the look that I'm shooting for with my 125.
http://img.tapatalk.com/d/14/08/12/ravudava.jpg

Doesn't look like too much in this picture but I now have the front end done and am plagued with the infamous 'seized swingarm bolt' dilemma (and have been for the past 3-4 months). A Tri-Z front end was a direct swap and the steering stops worked and the triples even cleared the rads on each side. Just gotta get new stem bearings though and it'll be halfway there.
http://img.tapatalk.com/d/14/08/12/ry5a2ady.jpg

But I do know where one that was an original racer is sitting
http://img.tapatalk.com/d/14/08/12/7uzuga9y.jpg

Not sure what year CR he used for this one though because of the white shrouds and I couldn't see back to the rear end to see if it was right or left side drive


For the swingarm, I have a complete blaster swinger/carrier/axle laying around that I plan to mod up and go to a no link rear suspension with

[just ben]

Be aware that the tri z triples have 8 degrees of rake in them and you will probably have to make some frame mods for them to work right. That is what I used on my rm 80 conversion and It took a bit to make it handle right. If I still owned it they would be the first thing to go. If anyone is interested in a mini 2 stroke trike, I have a Kx 60 that could be converted. The price would depend...

[C.J]

Thanks for the tip Ben! I knew they had some rake in them, and the 82 125 has a good bit of rake itself. So I figured if have to do a little tweak to get the trail back where it needs to be. Do you think the fact the Z is trailing axle will help any?


Since my kart mill 02 CR85 burnt a few weeks ago, I may even convert it over and keep the USD forks. Depends on if there was un-seen damage done to the swingarm in the fire.

[Samjp22]

this makes me wanna build one of my 70's into a 2stroke. know where theres a cr80 i could probably pick up for cheap. I dont think coolpool would let me start this project until my R is put back together lol

[Jason Hall]

206633206634I used a 86-87 200x carrier, axle, and built a custom Swingarm on this little CR60/zinger. The 86-86 200X carriers are getting hard to find, but the are the narrowest carrier I have been able to find with the easy concentric chain adjustment. I actually cut the rear carrier section off of a stock 86 200X and made the front pivot collars, then used the CR60 bearings so the Swingarm bolt would fit the frame.

Did you have clearance issues with the rad shrouds hitting the forks/trees and if so, how did you correct it?

[Jason Hall]

I made small brackets with small flat plates on the inside to keep the shrouds from bending in when your knee was pushing against them.
