My first post... I have always ridden red and now I own the heaviest dirt machine known to man...that is not John Deere green... I plan to do the basic mod's which have been tried and true by you guys on this site. I plan to start with the intake mod's, like slide drill, snorkel removal, uni filter, and jetting. I will wait until later to modify the stock exhaust. I see a lot of guys listing the 55 pilot jet/158 main jet combo, but it seems most apply this with an aftermarket exhaust or stock with mods. With everything but the exhaust modified, is this still a good combo or would it be too rich? It seems like it would be a little excessive without the exhaust mod, but I am not sure how lean it runs from the factory. I have seen quite a few comments of guys leaving the stock exhaust alone as they say that the power increase is marginal for the price. Any feedback is highly appreciated to save me some trial and error. I look forward to getting on the team in the future, it is a great site.
