xr 200 help

[trucktramp]

I recently picked up an 86 xr200 cheap for my g/f to ride. It was smoking pretty bad so I knew it needed a top end job. I haven't torn the motor down yet but I figure rings and valve job since after the last ride it wouldn't restart and has very low compression. I am thinking about putting a powroll 218cc stroker kit in it (so I can have fun on it too). Anyone know anything about them or have any suggestions to hot rod it (if that is even possible)?

Powroll and BBR are the two best places to go for all your XR200R needs. I know a guy that did the 218cc stroker, along with a BBR frame kit and absolutely loved it. He raced off-road against full size bikes and was consistently on the podium. www.powroll.com www.bbrmotorsports.com

I installed a 218(or so) kit from Xr's Only in my son's '86 XR200. Siginificant power increase esp. bottom end. Definitely more fun to ride but harder to kickstart. No reliability problems, a little more vibration

Also, don't forget to change the cam chain. All of the older 200's I see need seem to need a new one. This one item can prevent all sorts of trouble down the road.

I did a modified 200 with a very high compression piston in a stock bore/stroke. I added a hot cam, valve springs, big carb, big exhaust. The bike ran very well and would top out over 80MPH. If I were to do it again, I would go for the bigger displacement on a stock cam, wich would result in the extra wheelie power I like so much. In other words, my setup was lacking in low end torque, but had plenty of top end.

Good year-solid playbike; came with (relatively) long-travel suspension, zerk fittings, lights, and an odo.

My oldest son's first man-bike was a '96 (essential similar to yours). When he grew I put the above on it off of an '85 (blown motor) and we got even more time on it/life out of it. The thing slightly better ran well with little attention like opening the airbox, hi-flo airfilter, and rejetting.

Only thing I did not like about it was the odd 17" rear wheel and tall hump-back tank typical of pre-YZWRRMFKXFCRFX strokers. A seat upholsterer did a tall foam job for it and that helped.

Put RT gold valves in the forks for neo-cartridge action. Four Strokes Only sells a muffler insert (from another bike) which opens up the exhaust but it remained relatively quiet.
