MTTB: The Restoration of a Track Bike

[toratora]

Today we went to the track. But Mikes bikes wasn't ready before we got there. We still had to fit different forks, bleed the front brake, add a new Res to the front brake, and tune the carb. All of this took me most of the day. Oh well. Didn't get much in the way of photos either. ¯ \_(ツ)_/¯

Lets start with the forks. Mike really liked how they were working. Once we got back I took a look at them. The left one seems to have leaked a bit, but the right one seemed to be okay. We will have to do some more testing.

The drive out to the track was beautiful.

It was time to work on my Track Bike. There wasn't much time left so I only got to tend to the reed. As you can see the old ones were tattered. The Malossi reeds look quite nice. And they worked nice too.

Pretty bikes.

Hey Cats, well we got to do a bit of work on MT Mikes track bike today. I pulled the top end to check on it since when I put it together I didn't have the time to do all the things I normally would do—like properly chamfer the ports. As you can see there is a bit of scoring on the cylinder.

Another thing we wanted to get to was the fork leak. We picked up the Motion Pro fork seal cleaner, but ran out of time. We'll have to try it out net time.

Mike painted up the plastic bits in white.

The tank fairing looks awesome in white!

Tora, would you post a picture of a really well chamfered cylinder?

So it seems that the AllBalls seals aren't a good enough fit for the newer GPR forks. So all of the Second Edition GPRs do have to have that off sized seal. I've got some coming from EZ Parts. Once that's going on MT Mike's bike should be in good shape. He picked up some jets, and the next time we get to the track we'll do some fine tuning.

It's been a while since I've done some track bike action. Today I headed over to MT Mike's place to get his bike into shape. Had to get the fork seals done, put on some plastics, test for leaks, and basically give it a once over. Everything went well. I also picked up my track bike for some wrenching action, but ran out of time to get any done today.

We went up to Sonoma for some circuit riding. The White bike is MT Mike's, and the Black bike is mine.

We finally did the PWK carb upgrade on MT MIke's GPR. This included the Malossi intake reed kit as well. For the carb we went with the Polini 24mm PWK. Mike had a K&N filter that we used, as the Uni filter on the TM24 doesn't fit the PWK.

The main jet that came with the carb was a 105, which seems to be working great. We'll probably have to do some tuning at the track, but for now the bike is running very strong. Better than it has since we picked it up. Should be a lot of fun on Thursday.
