I let a local expert (Jools) have a go and he loved it (Currently rides a GasGas 300 ) he said he tried the Mont and its crap in comparisson

also the odd bit of tripe I see

Aye

I have also found a clean air filter really makes a difference to starting

i know we should all change filters each time we ride but trials riders dont all tend to look after there bikes as well as they could

on my old 2t's i did not seem so crutial but bang in a clean one and its first kick every time

Hey Ishy,

Sound like you had a good scare !!! Yep they sure are neat to work on, very easy to slide rocker shafts out , and replace shims.

I checked both de-compressors on the ones I`ve worked on, and they were very free , with no sign of sticking. Shims on both bikes were not changed, but on re assembly, both de comps worked. I looked at the triangle plate clearance to de comp, and it`s clear, so still no idea on what I changed.

RE 500,

Sounds like your definately onto your problem. .2 mm error would affect the de compressor action. Shims should be available from your dealer ? here in Oz we got in four full sets, with the first batch of bikes.

Your not going to believe the differance when you get it sorted.
