Just found this site and I am hoping ya'll can help with a few questions. I bought a 95 KDX200 last week. Due to the owner's neighborhood I wasn't able to ride very hard or long before buying. I haven't had a dirt bike in about 15 years and have been riding streetbikes. The bike is completely stock and the owner (original) said the motor is also stock.
The problem I am having is the bike spits/sputters at half throttle and won't go any farther power-wise. It starts easily and idles good (altho' it knocks fairly loud at idle-exhaust leak?). I thought it must be starving (gas) or choking (exhaust). Last night I pulled the exhaust off and looked down the pipe and there was quite a bit of carbon build-up. I chipped what could be seen out, but that only covers the first 4-5 inches of the pipe, ran it again. Now it still sputters at mid-rpm, but is able to get past and continue, I'd say it's improved about 50%. Looking into the exhaust port, everything looks good and clean in there. Is there a way to clean the rest of the carbon out without slicing the thing open or should I just get a new pipe. I read another discussion on pipes and of course everyone has their favs. I ride whatever I can get myself into - track, woods, fields, etc.
My streetbike is a ZX-11, so obviously this KDX feels slow, but does it even have a top end?? It seems to just have low-end torque or is this still due to the above mentioned problem?
and finally, if I did get a new pipe, is it just the expansion chamber and I use my stock muff/spark arrest, or is it a complete system?
thanks in advance
