mofoka Posted March 21, 2009 Report Share Posted March 21, 2009 I'm not happy with how she runs. So I've finally cracked the carbs open. I'm thinking it's stock, because the main had a little 200 on it. 2 things. 1- what is the stock config? 200 main 40 pilot and clip on the 3rd position? 2- I'm thinking for me I'd go with 260 main 42 pilot and leave the needle. What do you think? I'm at 3500 to 5000 ft. FMF fattys and PC2's. 2 stage reeds. K&N filter with modified lid and no snorkle. (don't mention to do a plug chop, I'm looking for a starting point) Quote Link to comment Share on other sites More sharing options...

blaster2006 Posted March 21, 2009 Report Share Posted March 21, 2009 I'm mixing 32:1 belray and I usually run anywhere between 10-30 celsius. with all those mods you were running 200 mains? and yeah stock pilots are 25 Quote Link to comment Share on other sites More sharing options...
AKheathen Posted March 21, 2009 Report Share Posted March 21, 2009 if the oil is doing good with the 200's, then i would drop to 40:1 and start with 310 or 320 mains. check your pistons too. Quote Link to comment Share on other sites More sharing options...
mofoka Posted March 22, 2009 Author Report Share Posted March 22, 2009 with all those mods you were running 200 mains? and yeah stock pilots are 25 yup... that was my first time looking at them... I'm hoping that will wake up the engine. I'm still thinking 270's anyone else's opinion for my set up? Quote Link to comment Share on other sites More sharing options...
mofoka Posted March 22, 2009 Author Report Share Posted March 22, 2009 Any one?? AK's recommending 280-340, any one else willing to supply some advice for me up at 4000+ riding? Quote Link to comment Share on other sites More sharing options...
Mjv420 Posted March 23, 2009 Report Share Posted March 23, 2009 At your elevation I would start at around a 300 main or higher, and a 27.5 pilot. Not trying to turn your thread into a sales thread but if you have stock 26mm carbs I have a bunch of jets I do not need anymore from 280's up to 340's.

If either of you need any of these let me know via PM. i'll let mofoka have first dibbs. i'm fine with 30's right now, but my 25's and 27.5's are messed up, and i'll need more mains by spring Edited March 23, 2009 by AKheathen Quote Link to comment Share on other sites More sharing options...

Michael Jackson Posted March 23, 2009 Report Share Posted March 23, 2009 (edited) Any one?? AK's recommending 280-340, any one else willing to supply some advice for me up at 4000+ riding? my guess would be around 260, with stock pilots, with those mods and lid on, and 5000 feet up is pretty high, air gets thin i run similar and run a 280s with a 8x3" hole cut in my lid, and im riding 500-1200 ft elevations only you can ride the bike and see what works best though, with it goin into spring now, its gona warm up and that will richen your jetting up as well, remember that, need to lean out in summer Edited March 23, 2009 by Michael Jackson Quote Link to comment Share on other sites More sharing options...
