Hey guys need some help, just got a tm 38mm for my scram.400 4x4. Need to have a baseline on where to start with the jetting. Main,pilot and air screw. I have a dg pipe .060 piston and going with carbon fiber reeds. The air box is modified also.( more air) I dont know where to start. Thanks.

 

i have a 38mm TMX flatside on a mod xplorer 400 and use these settings: 390 main jet, 35pilot and just over 1 full turn during the winter, i'm going to try 1 1/4 to 1/1/2 turns when it gets warm. i have an AAen pipe and mod air box plus other stuff and do not have any problems with these settings. I like to have my plug just damp - runs alot cooler this way in the summer when racing.
later
hunt

 

Great thanks alot kyxplorer
