XS650 Addict
Hello all,
This is my first post to the forum.
I picked up a 1981 XS650 Special a couple of weeks ago that was non-running. I paid $650 for it. I ordered carburetor rebuild kits from MikesXS and I got the bike to fire right up, however, it was running rough, which I expected because the mufflers had several holes that were quite large.
I have cut off the mufflers and I am currently running open drag pipes. In addition to this I am using MikesXS Performance pod filters.
With this setup and stock jetting I can get the bike to idle (very loudly), however, I have NO power at low rpm. When I open up the throttle the bike will general sputter and die.
Obviously I need to rejet. I ordered the Heiden Tuning kits from MikesXS and I plan on installing that tomorrow. I am going to go with the 145 Main and 45 Pilot. How does this sound? In addition I am going to install the adjustable needle. Is it truly necessary to drill out the vacuum slide? I would like to avoid any permanent changes. ALso, I have been told the air screw should be backed out 3 turns from seated, as opposed to the factory 1.5 turns. How does this sound?
Finally, I just installed tonight an adjustable washer that goes into the exhaust pipe which can be controlled, to add some back pressure. I will try to ride the bike again tomorrow before I rejet, but I am sure I will still have to rejet.

Oh, is it possible to rejet without removing the carburetor from the bike?
