I wasn't planning on it haha. I've been around other forums, this is really my first time messing arounf with 4 wheelers though. I did find a service manual with tolerances, so I will probably pull the motor apart and start checking specs to see if the cylinder is reusablehang in there, we got some pretty smart sport atv members around here !. I am not one of them ?!..lmao. i'm mostly utility models, and old school models. anyway, hang tight, someone will be along soon to point you in the right direction !, oh, and please do not make/post more than one thread asking all the same stuff as you have here ^^^, that won't get you help any faster !.

I already purchased an aftermarket full exhasut. I'm unsure of the brand but it was a good ebay deal, and it looked a lot newer and nicer than the factory exhaust. I planned on jetting to match that as well as running a custom intake that will hopefully supply more air to the motor. I'm familiar with chevy motors, and I know a lot of them like gasket matched porting. Is that something this ex motor will like? or would I be better off leaving it alone or having it professionally done? Are the hot cams worth it? I was looking at maybe getting a box to raise the rev limiter, but I probably would only do that if I throw an aftermarket cam in. I doubt the factory cam makes power past the rev limiter.I wouldn't bother with a big bore kit. There's just not a lot of bang for your buck going all out modding one of these machines (ask me how I know).
In my opinion you should bore it to the next largest size where the cylinder cleans up and rebuild it with quality parts (OEM in most cases),work the exhaust and intake ports over a little bit and install a new cam chain.
You can always throw in a hot cam or something but it's not a huge difference over stock. A more open exhaust system with proper jetting does help some also but it comes with a price and extra noise.
