[QUOTE="omrik88, post: 1376770, member: 116035"] [b]Some more new details and a pic[/b] Hi again, I checked Keihin website and DG performance. there is alot of info and charts about what i should do and what carb parts are available to buy. this is very complexed tech stuff so i'm not sure what to make of it. Some new details that i have learned: *This carb is of the "PJ" series by keihin, and from what i see,the idle adjust&choke are originally on the same screw. *the "Main" jet(the one where the needle goes in)- is fixed in and cannot be removed - and from the keihin charts it seems that this jet is suppose to be removable! , maybe that's one part which was modified. *the pilot jet/slow jet(if i got the terms right) shows the number 48 with a "star" mark next to it. *the biggest jet where the fuel comes in, shows the number 3.6, with the same "star" mark. i'm not sure if it's removable or not. *on the Left side (choke side)there's a code: PJ 36DGC GG *inside the carb,above the float bowl,is marked the number 20 or 2.0 , if that means anything. *I know for a fact that this carb was bought after the original(35mm) was finished, and worked great on the STOCK cylinder, even better than the original carb - more power,higher rpm,faster response. The problems started when the cylinder was changed to a MODIFIED Fredette Cylinder. *I don't know if the current setup in my carb is the originall one ,or someone might have changed it. (i had this bike years ago,then sold it and bought it back...it has a long history). *plus, there's also the PSI chamber and DG silencer, which probably affect tuning. I hope this info&the pic will make things clearer. Any ideas where i should start? any info that i should be asking from Keihin/DG? Thanks for the help!!! :) [/QUOTE]
