I know it's been said before and will stir up the hornets nest but.......
I just hope Twinshocks aren't allowed to get out of hand like 'trick' pre65's.
I think one of the main problems we have is that the title 'motor cycle trials' covers two totally different sports.
People can't seem to grasp why some of us ride old bikes.
Is it also an age thing? Classic trials seems to be booming but not many youngsters involved.
I use both an original unit and copies made locally on my bikes and when fitted correctly they work very well and look much better than the original set up.
I am using a carbon fibre outer cover at present.
I've just arrived home after riding both days at the show and had a great weekend!
A lot of effort from a lot of people. Well done and lets hope it's back next year.
Most of the sprockets have a shoulder on the engine side for the spacing. There should also be a an inner circlip for the sprocket to then sit between the two.
Thats all you need as long as the output shaft and sprocket splines are in good condition.
Classic Offroad sell the Domino levers on ebay. They may have a suitable cable as well.(Kit)
You may have to make a small bracket for the lower end and bolt it onto the rocker box side.
You can also use the de-compressor as a kill switch.
You should fit the de-compressor if only to look after your kick start and starter gears.
The auto system is easiest to use as it takes care of itself, but I do prefer the additional manual lever and you soon get used to using it.
You will not damage anything by using it at the wrong time as it only lifts the exhaust valve slightly.
I now use a WES with the shorter back box which seems to let the engine run and rev out better.
The after market alloy systems don't work much better than the original but are much lighter.
The top mounts can be moved behind the frame tubes but this angles the shocks in at the top and there is then an issue with exhaust and chain clearance.
Open your legs a bit!
You will need two bolts on the rear and one on the front to stop the tyres creeping. I seem to remember adding extra security bolts to the little scorpa I had.
