98_sheester Posted May 18, 2015 Report Share Posted May 18, 2015 If the bike is running bettsr with the choke out you might be a little lean usually...also when you get your slight bog does it hesitate and not wanna go faster or does it hesitate and then goes?

600racer Posted May 18, 2015 Author Report Share Posted May 18, 2015 All right folks I was able to pin point where the problem was at I found that no matter what pilot I used herr recommended 48s lowest I had was 52s only could go .5 turns on air screw through some 55s in all the way to 62s I could not get past .5 turns through the 52s back in bike ran awesome so through the 55s in still ran awesome so I don't what the deal is with the air screws are so called herr and they said if that's where the bike likes it and runs the best leave at .5 so I'm going to try and lean it up a tad cuz I all ready order the dam 48s and some 50s. Any of you guys ever have this b4 Quote Link to comment Share on other sites More sharing options...

sleeper06 Posted May 21, 2015 Report Share Posted May 21, 2015 I have seen relatively stock motors take 62-68 pilots with ghose carbs, I was a lil baffled but it wants what it wants. I usually keep adding pilot till the screw operates Quote Link to comment Share on other sites More sharing options...
