Do you think normal that with my set up a jet pilot of 55 is to small? Till yesterday when I start from the stop position in first gear I have a bir Boooooh with no power I have to clutch I make a big throtle to start normaly... and yesterday I put at air srew 1/4 turn and the problem go away so I have to put a bigger jet than 55 but It's so big... Do you think my problem can come from a air entrance from the case of engine? How can I check this?

I'm at 250 meter up the sea level and the t° is 20c°. I don't find a good set up for my oko 30mm. Somebody told me the reason of this is , maybe, the oko carbs who need a k&n air filter without air box.... what do you think about that? He told me the oko are compatible 2 stroke and for stroke and they don't work with airbox???

Hi Everybody, I'm from Belgium and I've just finished to built up my banshee. So now I have some problems in choosing a correct jetting... so I know that you have a lot of same questions but I will hope some of you can help me. Here is my set up : - Stock engine - boyesen reeds - oko 30mm - spacers of 5mm between cylinder and reed cage - FMF SST - Open air box with a foam filter So can you give me the best jetting for this set up THANKS VERY MUCH
