Title: Mikuni 36MM jettting specs for 1981 KTM 250
Post by: JCHubbard on June 05, 2008, 10:09:13 PM
Hello Gentlemen. I've got a Bing 54 on my 250 and this carb is almost completely kaput!...I just recieved a new VM Mikuni 36MM carb and was wondering if anyone here has any experience with the Mikuni jetting specs (sea level) for a 1981 KTM 250 GS?...I've searched all the previous Mikuni posts and what I gather is that you should definitely go fat (240~410 range) on the main. On my 79 Maico I've been able to track down some old Mikuni specs for a ballpark starting point and it's been very helpful in getting the bike dialed in. I'm hoping that some here might be able to provide with a little insight as to where I should start when jetting this bike.

Thanks,

John Hubbard

John,

You may want to ask your question on this site http://www.ktm495.mxbikes.com/  
They have a lot of experience on the 81 & up KTM's.
