Just to let you know, the Beta never did roll back well in gear. I started out riding an `89 and always used ATF. Never had a problem shifting on the loop, no matter the year. Always riding at high altitude. I`m sure it always ran plenty hot. Have you done any mods to the engine?
-
Just FYI a floating disc comes that way new. I have never replaced the bushings or seen someone else replace them.
Ps, The 2001 was one of the best looking beta`s ever. I had three that year. Have fun with it!

Jon, this guy lost his motor last year and just now finished it. I doubt that it is the spacer causing the ping. He was chasing timing and now the intake. Either he has an air leak or a carb issue. Just my two cents.
-
The question might be did you get the replacement swing arm as many were replaced under warranty.
-
I understand you just rebuilt the motor. I would start with what jets you have in it for your elevation. The `02 also had mag cases, so the idea of a leak test is in order. Did you do the rebuild or someone real familiar with the pro. The cases were different on the `02 so the center gasket could be suspect, so was the clutch cover gasket. The `02 had a crazy amount of problems, which can be worked out with patience and lots of investment. That is why they never made a parts list.

I`ve never been a fan of the TYZ motor ( Though I love Yamaha`s) A very clean (cheap) one would interest me. Just from the forums, even the clean one`s have a crack in the mid-pipe close to the motor.
-
There has never been a parts list for the `02.
-
Just so you know, you can drill out the domino throttle so the stocker will work.

Yes, the whole yoke, axle and spacers. Quite a common mod in the western U.S. I`ve never done one myself, but I`ll try to find some pics.
-
Are you sure that you have enough play in the lever at the master cylinder?
-
Even better! I always love projects. I thought it sounded like the twin shock was a new adventure! I`ve competed in several vintage events on Bultaco`s. They are better to look at than to actually ride. Just my opinion.
-
Did you not ride it before you bought it? It would be a hard bike to ride if you did not compete in the 70`s. I never liked the Sherpa t`s, was an Ossa fan and really like the late model Cota. (330,350) Had a Cota 200 that rode great, just did not have the power once our vintage club went to larger obstacles for the hard line.
-
Change to the Alpina or Pursang style stem.

You should take the fork apart and make sure you do not have a broken spring. I have not heard of any on the Evo, but it is not that rare on a trials bike. And springs do wear out. The old gassers would totally sack out in a year of riding with two springs when most of the bikes were running one. Also you are chasing numbers that mean little for most trials riders. Yes, you are on the heavy side. But it is more important that the suspension works together front and rear than anything else.

-
There is a thread on here where the numbers were in the 700`s as it went through more years than you might think.
-
I`m working on SM158. Has the same gawd awful pegs as yours. I also ride with another vintage rider that uses his highboy in all of our events. Up until now was the only two I had seen in the states.
-
You could just do the steering stem mod.
-
You need to ride a trials before you mess with the gearing. Riding an event is very different to just riding around.
-
The gearing is good, but the o-ring is all wrong for trials riding. Sure it will last longer, but it eats up the power. Don` t believe it? Just try pushing it down the street.
-
The bike is lean from the factory. You have to jet it richer to run! I`m at 6500 ft elevation and it was too lean!
-
The rivet itself could be coming apart. Back in the `old ` engine, just take the clutch cover off and it is probably an easy fix. Also the shift shaft could be bent.
-
So what are you mixing the gas and oil at?
