Got a 2 smoker
 

Picked up a 2 smoker for cheap - 98 CR125. Too cold to really ride it but it seems to run fine. I'll either keep it around for a bud bike, sell it when it gets nice out, or I've thought about pulling the engine and pipe and putting in a mild 4 stroke. Anyone here have a clue if a chinese 200 could be wedged in there? I realize this is a vague question but I thought I'd see if anyone here has done anything like this?
It would make for a heck of a bike for a beginner!

I don't know if it'll work, but I've always liked the idea of putting chinese motors into honda frames. Best (cheapest) part of both worlds. :wink:

Its been many many years since my 2stroke bikes, but the little 100's and 125's would run circles around my 250 HiBird.

I'd run it as it is.

The 2 stroke engines are a bit smaller than a 4 stroker and would make it difficult to swap in a 4 stroker.

I have thought about a ninja 250 engine in a xl250r frame though I'd like to put it in a china bike frame but I think it would tear it up.

Ya the 125 2t will blow away any 200-300 4t, but I just thought about it for a nice, plush, easy riding bike for a bud or my wife. :D

Between 5 and 6 k. Outside that the 4's take over pretty much. :roll:

I had a lifan 200, I now have a KLX 300 and DRZ 450. I haven't even got my 125 out of 2nd but I know the 200 or 300 wouldn't keep up with it in a drag!!
Now if you're talking about riding one all day on gravel roads, then I'd take the 300 over the 125. :roll:

If you do make the swap, I might be interested in the 2-stroke you take out . . .

Luke, 11: 21
Rush, 21: 12 :D

My bike is named Barchetta, from a Rush song. No Hubris Intended.:wink:

Keep the 2 Stroke LOTS more power than you'd ever see from a Chinese 200, 300 what ever.

Yup, a 2-stroke with the same displacement has twice the power of a four stroke, in fact a lot of the meets will classify them as equal, i.e., a 250 two-stroke against a 500 four-stroke.

I had a 250 Polaris that wouldn't take a backseat to anything, and it was light and nimble -- could take it places a mountain goat wouldn't tiptoe . . .

True. I know about the difference in power and such. Took me awhile to be convinced of a 4 stroke MX bike. Only reason I would want to switch out motors is to have a nice, light bike that could tractor thru the trails instead of fly. :D

Finally got the CR out for a ride this weekend. I was having so much fun on the light bike I let the other guy ride my DRZ most of the time. The 2 stroke hit is a blast. :D

the idea of taking out a good running 2 stroke motor just blows my mind... 2 strokes are easy to work on, cheap to maintain, and a blast to ride.

Long live the 2 strokes!!!! nothing like the sound or the smell when you get a full line of them ready for the gate to drop. Now they are pretty much gone, and KTM's looking at mass producing zero-emission electric bikes -- won't be long and the kids will be walking around halls going wooosh wooosh instead of brrraaaaapppp braaaappppp. :wink:

Nice looking bike - keep it as it is and enjoy it.

nice bike, i've been thinnking of selliln all three of my bikes to get a used two stroke, 125's usually put out upwards of 40 hp stock, not too shabby!

the more i ride, the more i like to wring out the motor anyways, and two strokes are perfect for that
