yes i know i asked this question before,
I hate to say this but if your gonna race road course. Then I believe and many experience racers would agree. Handling trumps hp anyday of the week in road course racing. I seen this play out many times on the tracks.lol You get the guys with waaay more hp going over to the under powered bikes. Looking them over trying to figure out. What the hell just happen,as they look at the engine in the less hp bikes.lol Skipping over the most obvious,suspension,tires and brakes. I'd work with the motor get your bike setup to where the bike handles great,then build up hp.well i dont plan on racing the bike, that one just seemed to have everything i wanted, i dont know how to change pistons and cams anyways. if someone could tell me how to take the head off to port the cylinder intake that would be great. http://www.ooracing.com/store/index.php?act=viewCat&catId=130 this site has alot of lifan 140cc performance parts.
Then I have some questions,what bike are you riding and have you any previous road course racing experience? I can already tell you haven't ridden your bike hard enough to find out why some of the stock components are no good for racing.i just got new tires, my brakes work fine and iv never felt any problem with my stock suspension. I really dont know why everyone hates it so much.
