Official count at the last New Mexico event was 106 riders which might be a club record. We even were missing about 15 riders who rode the last event. Now a days it looks more like a national than a club trials. In fact we have too many new riders as our use permits top out at 80. Our succes comes from the fact that most families in our club camp for two -three nights at each event. We`ll have a total of 15 events with 6 events being two day events.

Sounds like it just broke off. Back in `02 they were leaving the bolt out for more oil flow?!? So it really has nothing holding it in place but all the other parts being aligned in a small space. I would not worry about it.
-
Did you leave the petcock on? Is the plug wet now. Might just be flooded.
-
You did not mention the year. Some times 12 to 16 0z off the flywheel will waken it up a little.
-
2001 national was at the same location, and we had a fine bike toss. A month or two ago was a link that had a Fantic section as the bike of choice this year!
-
Someone needs to try and get a picture on here of the bike toss saturday night. Crazy tradition taking a running motorcycle and crash it off a small cliff for entertainment!!
-
It does look alot like a flywheel off a mid 80`s TY.
-
Have you cleaned the carb and checked the pilot jet? The knock could just be a lean condition from a blocked or too small of jet. It will also fix your idle problem.
-
You left out a few variables on what you are looking for. Skill level, mechanical appitude,(since you are a long way from a dealer). And are you going to compete or have long days just having fun!
-
The only manual was a basic owners manual with capacities and normal maintenance. No service manual. You might try a search on this forum as this has been asked for before.
-
You might try replacing the top hat and shift spring. They are usually sold together and it`s cheap.
-
It has been too long to remember, but you will have to loosen and maybe remove a few. The sequence was like every 4th one. Good luck with the stuck nipples.
-
If you have had any brake fluid at all on the pads they will have to be replaced with a fresh set. Keep trying on the bleeding as it usually is not an easy job to get all the air out. You might also need a master cylinder rebuild kit as that could be the whole problem.

Start by pulling of the flywheel cover and drying everything out. XCheck all connections. 99.99% it is not the coil. It could be the wire or cap or stator, but not the coil. I worked at a yamaha dealer for years and can not remember a coil going bad. Lots of CDI`s and stators, but the only coils we sold was to backyard mechanics.
-
I was employed at a yamaha dealership in `86 and I can not ever remember wanting to ride a 250 off the lot. They were under powered and over geared. So the bike is probably running great for what it is. Hope that was gentle enough!
-
I always used NGK. stock should have been bp7es, but we always ran bp5es at altidude. You might remove the flywheel cover.(right hand side) And check too see if the flywheel has any play. The main bearings where always a culprit of timing issues.
-
Only two years of the 350, 1985 and 1986. The `86 had a reomote resovoir for the rear shock. `86 had alot of other improvements also, mainly the frame. Oil quantity is stamped on the case by the kickstart. I believe it was 650 cc. 10w30 would work, but seems I always ran Bel Ray LW gear oil. Great bike, I used a yz125 wheel and master cylinder for a disc upgrade of the same year. Enjoy.
-
You would think that is either in the pilot circuit and/or timing. And I`m sure you have checked both. I can see the concern since I always thought the Bul kickstater was an awkward feel. Any good running bike should always be one or two kicks. Good luck.
-
Just finished a long hot 2 day event. Still had to score a section in the afternoon. Removed my sweaty gear to something comfortable to score in. Just opened a cool beer and with out takin` a sip set it on the ground to start my `92 Beta. Damed if the kicker slipped. (started it with the right leg) Put the whole thing in my right calf. Three layers of stitches, a drain and I finally quit bloodyin` the bed sheets a month later.
-
Might need to change the shaft also as they tend to get a groove quickly.
-
Forks will also act this way when over filled. The problem lies in adding the recommended capacity, but not taking the correct measurement of level afterward. Or another way to look at it was not completely dry when the new fluid was added. Try calling RYP for a correct measure ment with the forks collapsed.
-
It was the worst year for a gasser, anything 2004 and newer are more desirable. When running they ride great. All problems they had could be corrected, but at a price. Better be capable of a complete rebuild. ( splitting the cases) They had shift fork/shift drum problems. Clutch side case, clutch plate swelling, Kick start, kick axle/spring/idler gear. Just to name the basics.
-
The bikes weight savings thru the years have come with a price. Compare the current trials bike to any other motorcycle out there. Trials bikes are now border line under engineered to the point of a major break at at any severe ride, and need a lot of attention. Go back to any vintage bike, and the bike was ment to take quite a beating. But then thats why they rode like tanks and the modern bikes are too much fun!!
By the way the `06 Beta is a great bike!
-
If you decide on a tube the dunlop 803 works well. Stay away from the IRC because they spin slightly. It is the 'easy' fix.
-
Remember the simple things like the fuel tank not venting properly, and or the floats sticking. Both common problems on old iron.
