200m Upgrades

[hansleydd]

For all the smart guys. I have an 85 200m that ive owned since she was new. What easy power upgrades can I do to her. She is original and I'm trying to keep her that way as much as possible. Thanks

83-85 200x piston & carb...will give it a little more get up and go..you could also swap the 200x header pipe too, but not much gain there and requires some tweeking on the factory muffler. If the motor needs a rebuild, the 200x piston is a no-brainer, since it's the same price as the 200m, but has a flat top and is higher compression
