What brake plate are you using ? If it's a Fantic 300 it has different shoes from most other grimace brake plates.

Did you try a new plug as previously suggested ?

It's probably the crankcase drain which goes to the carb, looks like an Aprilia motor.

Ok for a straight road, to much leverage for sudden manoeuvres.

Dremel.

That's not an old trick, that's just you !

Patrik, I've pm you.

Lol, just wait till he discovers Morgan Freeman is black !

What country are you in ? Have you tried Wiseco ? http://www.wiseco.com/

Think 500g is nearer to the mark !

Your just being cruel .....

Probably cheaper to pay trials tax than drive thousands of miles to events.....

Good to meet you and your father too, you need to get the tx out from "under the bench" Is it Robin's Jumbo your working on ? Had a quick shot at the end of the trial, nice bike. I've entered Alwinton over that weekend, to many trials on at the same time.

Think it was Brownrigg, not sure of that part of the world. I was on my tx300.

tshock250, were you and your father at a Cumberland classic a few weeks ago ?

Husqvarna also have one that fits.

Defiantly have some climber cases, will check condition if your interested ? I'm in Edinburgh.
