Looks radical, but undoubtedly necessary. JP’s are always way heavier than standard. But did you also check the pin for lack of taper?

put it on the shelf , safer there than inside your engine . Talk to Stuart Tongue if you want to go faster .

You must be joking, I’ll give it a couple of months before the big bang...

I think this is what was done for a racing mod to lighten the piston in bygone years, you could buy them in this form new I think and think there were called slipper pistons.

Most interesting. I understand that this piston belongs to a Ariel 500cc Red Hunter and that the lightening has been very worthwhile. The bike has covered 7000+ miles since the work was done, I don’t think it has an easy time either! on long distance trials.
