hey whats up everybody, im jonathan from south mississippi,i ve been lurking on this site for a few weeks now reading alot of the tech articles and different set ups that everyone has so i finally decided to join. i bought a raptor 350 about a month ago and ive fallen in love with it. right now its mostly stock (that i can tell) except for a 14 tooth front sprocket and a motion pro twist throttle. the exhaust has the baffle removed and what looks like some holes drilled in the inside for more airflow.. :???: but it does sound pretty good so it'll do for now.
i've noticed recently that its beginning to smoke under heavy throttle and when i let off at high speeds so i see an engine rebuild in the near future. i've never tore into any kind of atv engine before but i work on heavy machinery for a living so it shouldnt be too hard to figure out.. but i just want to stick with the stock stroke for now, i was thinking about going with a JE 85mm replacement and maybe 12.1 compression, (i know i'd have to run 105+). along with a programmable cdi, k&n filter, and exhaust. not sure which cam would be best but all suggestions are welcome.
