Bigger holes?

[mhsilverw]

Any one with experience of bigger pistons - 375cc in the 3 1/2?

Gather 400 was an option when Darts were new...but as parts not available anyone tried the 375cc set up offerred by (I guess) NLM?

What does this deliver performance wise?

Only consider it if you are replacing worn or damaged parts.

You won't notice the extra if your current 350 is in good condition & well set up.

Spend the money on new tyres and a brake overhaul, instead!
