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?
-
Better to start slow and easy. I have seen many come and go thinking they are better than they really are. It is great fun. Just takes plenty of practice.
-
Get new cables, oil them well. Before you get them remove the clutch arm from the case and grease well. After all these years that arm needs some lube!
-
Just become a dealer! You can stock all you want! I have not replaced a hose in years. So not sure what the obsession is on hydraulics. Even counting our whole club the numbers are very minimal. Good luck on your search.
-
The manufactures do not make the brakes. I would say all this happened when we lost AJP. The farce with Formula was even worse. In a day and age where the brakes are a main way of riding technique, no matter the brand they should get more attention. Ask a top team member how often the brakes are rebuilt, I think you will be surprised. On the other hand my 1990 Fantic has never had any attention to the brakes, besides new pads.
-
First thing, did you leave the fuel valve on during transport?
-
Do an oil change with the proper amount.
-
Very nice looking sections Tony! I was looking forward to going this year, but some how our first Sunday of the month became the 9th and 10th for our local event. Hope you have a good turn out, looks like good fun.
