I run a 60 pilot jet in mine with no pinking, started with a 52.

Are you using the clutch when this happens? I`ve seen the plunger on the master cylinder barely stick for a split second.

750cc capacity = engine rebuild 650cc = oil change Remove clutch side case and clutch ass. Should just be a bad shift shaft or the other parts in the same area. Usually a very cheap fix price wise. Very rare to have to split the cases on the older models.

Sounds like the pilot jet and/or circuit is plugged. Also check the needle and clip is not moving in the slide. Usually some sort of meatal clip is held down by the spring.

wider pegs are fine, try 6 inch bars. Sounds more like you need to learn trials first. The bike was fine in stock trim, just takes alot of practice.

Lower your skid pan, remove 4 and 5. remove all the allen bolts. The case sticking on the lower right should just be the shift shaft. Just slowly work it all loose. Never remove #3 unless working on the kick stater.

Pull the flywheel and make sure the woodruff key is still intact. Very common problem. Then replace the intake.

You stated you removed all the crud off the pads. If the pads have had oil contamination they are basically ruined. They can be burned out with a torch, but new pads are the best cure.

Put a one way valve in the over flow.

As far as I know Beta never made a work shop manual. Bikes are all basic 2 strokes, except changes in the forks.

The 86 did have the better rear shock which made everything easier. Nose wheelies and hopping. The frame was stronger in the weak areas also.

Yes you can have the clutch just float. But all the parts fit the same just no bolt. It was left out for more oil flow.

The shaft and the spring should come apart together. I wouldn`t take apart any further till you get the new parts. If you are talking about the small center allen bolt, it is possible to run without it.

Yes, no problem the rad has to be loosened if I remember correctly.

Clutch needs to be assembled correctly, If I rememeber the TXT had a mark on the hub and one on the pressure plate. Any other tips Jon?

Did you just buy the bike or have you had it awhile? Did all these just happen or after it`s been apart. A little history goes a long way.

Wow, twenty two minutes and you`ve become the #1 BETA mechanic. All kidding aside good job.

Is it a rattle or a constant tick that changes with engine speed?

First off are you using the petcock? Has the petcock gone bad? And have you followed all the carb links on this site.

How about the big brass nut on the bottom?

Yes it was, just saw other posts. Usually over 6500ft I run a 130 main. Used to change to 25 pilot, but lately have left it alone. I would change the spockets, 10t counter or up 1 tooth on the rear.

150 main 30 pilot, should be a 135 main at your elevation.

Just tap the exposed edge of the bolt to loosen.

They should buy something in the 90`s disk brakes, monoshock, just something clean. Not sure if you had any aprilia,s down there. Best bike with no seat and still a flywheel feel. I prefer the new bikes,But still love the old style pull. They just need to decide.

If you are talking about the bolts on the spring, just use a small chisel to loosen. Then buy the 7mm head replacements used on the newer bikes. Quite simple. If you are in a hurry use the chisel to re-install.
