So, if the RT pistons are dropping pegs, what are the alternatives for the RT195/225 Cylinders? Asso?

When I was using asso pistons years ago I used to change the piston every year due to slight cracks showing where Adam described in his post. The one year I didn't bother because I hadn't done so many miles that year I regretted it. Mid way through the next year I had an inlet skirt fall off at high rpm in 3rd gear as I overtook a car which made its way round the crank and broke a 2 inch hole in the crank case just under the bump stop. That's when I stopped using asso pistons.
As Adam said. Its dependant on how manly miles you do and how hard you push the motor.

The things you do to get more air into that engine Eden ....................ha...........ha......
Did you also leave a large skid mark, in your underpants..........................
Scary really on the road eh.

Ron Moss Mitaka piston 70mm a,b,c,d £70 last time I heard.

Thanks, hope those a,b,c,d correspond to the RT kits A,b,c,d markings.

That's unlikely but if you wrecked the barrel then the replate should be done to match the piston.

warning we have seen rings wear so much that they have spun over the pegs and blown up at 600 miles!"

I have a T shirt with that on.

Any news about new pistons anyone.

Just heard from my mate,
MB have replaced the kit with a whole new one.
Top news,
