Gs82 Posted April 26, 2012 Report Share Posted April 26, 2012 Hi, I've just built a fresh top end and need to figure out where I should be at with my jetting. The guy I bought it from ($1200!) had a 310 main in one carb and a 200 in the other! I've got fmf gnarly's and a k&n with prefilter and no lid. I've got 290's in it now and it seems close judging from the plug color. But I'm wondering if I should upsize the pilots as they are 25's right now. I'm around Vancouver BC so elevation would be from sea level to around 1500'. Seems like I've got one plug darker than the other. I'll do a wot check and see where they are at. (just breaking it in so I haven't been able to open her up yet) Also can I use the Maxima Castor 927 I used to use in my RM 250? Quote Link to comment Share on other sites More sharing options...
