Is there a thread anywhere like the sticky in the 250EX forum? I'm looking for jetting help with my "new" 300EX. It would be nice if there was a summary of ball park jetting specs that have worked for others. I know it's not a black and white science, but it'd be nice to have something to start with.
Here's what I have. Wiseco 11:1 74.5mm piston, mildly ported head, WB headpipe and E Series muffler, K&N, no airbox lid. It currently has a 125 main and 38 pilot, 2 1/4 turns. I'm suspecting the main is lean. I used to own a built Banshee, so I'm familiar with how the different jets/needle work together. Any help would be appreciated.
