Ahrma is not very progressive, and sees trials as a thorn in it`s side. That was why we started Mountain West Vintage Trials. This year Itsa recognized the TY80 class, because our ty 80 team could outride almost all the riders in the other classes. No one likes to get beat by a mini-bike.

The single vent PWK does not vent properly on downs and ups in a row. Look at Copes picture. By the choke is a blanked out vent. Use a 3mm drill and carefully drill it out. You can feel when you have gone through. 8-12mm. Worldtrialchamp had posted this mod several years ago.

Something like that would bring on heat exhaustion in no time. Overdressing, particularly in clothes that don't allow sweat to evaporate easily can bring a quick end to a full days trial. You want protection, get an old style mx chest protector that allows air flow.

Do you still have the disc guard on with the spacers? If not the bolts shoulder can be too long.

The stock clutch is not so good. You might try Dennis at Overland. Myself I ordered sprockets to try.

Seems most have changed the gearing to 9 and 43.

Fast forward to easier riding, get a 9 tooth counter shaft sprocket.

I quit working for the local Yamaha shop in 1990. I just cannot get the part numbers out of my head.

Any Yamaha shop should have them as they fit many models. 260-14142-40-00 is a 40 pilot in a Yamaha part #.

What you really need is an air compressor and 1/2 in impact wrench. Along with a good socket set.

Seems like I saw someone with a later model pro having the same issue.. The early years needed prying out from both sides at once.

If you tighten the adjuster TOO much the fluid CANNOT return to the master cylinder.

You won`t miss it, it`s just half a screw and a hassle anyway.

We had an early `15 do it in our club. Not anymore that I can think of, but Ossa had a bad run of `14 factory coming out of the same place.

He likes to wrench, but owns several business`s. He just happens to be the CEO of the NATC. http://www.mototrials.com/

A 5lb sledge hammer will fix it in seconds, the weld a triangular tab.

Was it this Brad? https://www.youtube.com/watch?v=17TuJX5EN6A

Like I said I had my kid start it for me till I got it. But he`s 6`4.

Actually on the Gasser using your body weight is a no. It will accelerate the wear on the kick start pawl (Bart) and could break the case.

First loosen the adjuster on the front brake lever until you have excess play. The adjuster being too tight is 50% of brake problems. There have been many, many posts on this subject. http://www.trialscentral.com/forums/topic/6251-bleeding-front-brake/?hl=%2Bbleeding+%2Bfront+%2Bbrake

Well we have people that have been riding 3 or more years, all under the modern rules. They still seem to look for a spot to pull the clutch in and just stop, not just ride all the way through. Or they will try to balance while using the clutch for no real reason. If they would of never stopped, would have easily cleaned the section. Just mind boggling that this goes on month after month. From my very first event, the clean was the only score I wanted. These riders insist a three is the safest bet. But I`m glad they ride as we need the scorers!

Because of our stupid all day dab rules, trials has hundreds of new riders that really have no real control other than pulling in the clutch and hitting the brakes while dabbing. You are not riding the bike anymore, that is overuse of the clutch! People do this over and over in every section and think they are riding trials. Of course all the good riders use the clutch 90% of the time. We are talking new riders, they think the clutch is there best friend. When in reality every time they use it, a dab or two is the result. Most never learn throttle control, just panic, pull in the clutch and dab. I could take pictures all day long tomorrow at our event of this happening.
