And then there`s the mud with no traction, full rear brake (Yes clutch is used) to get the front up and over an obstacle and at the same time the most traction available. All done with the rear brake, instead of wheel slip.

I will again be Trialsmaster for ITSA Nationals rounds 5 & 6. It will be hosted by Mountain West Vintage Trials assoc. http://mtwestvintagetrials.org/event/sipapu-nm-aug-13-14-2016/?instance_id=318 Once again it will be at Sipapu Ski Area in Northern New Mexico 20 minutes from Taos. https://www.sipapunm.com/ One of the finest venues in the country for the sport of trials! Great terrain, nice friendly location. Perfect vacation for rider, wife and kids. Do not miss this event! August 13 and 14th. Top riders in all classes! Expect to get beat by the League. Our local Yamaha Team on TY 80`s. This is not Ahrma boys, we ride real trials! Come enjoy the fun! Classes for all years of bikes. Classes for all abilities of riders. We love to see the modern guys get beat! Always a pot luck dinner on Saturday night.

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.
