Yamaha TRX850 Enthusiasts Forum

I'm almost close to the point of being able to properly fit these 39's but I'm still off with the jets. I'm starting with 155 mains, but what about the idle and pilot jets? No one seems to have mentioned changing those yet and I wondered if anyone actually had?

I just bought a 39MX for the KTM and the guys on the KTM board have a whole raft of information on jetting all the way from idle to WOT ...
