hi to all enfied riders I have never used this before so
I am rebuilding my 1988 350 superstar and I am using piston part no 17459 supplied by Hitchcocks this has no slot on the front skirt has eney one used this product before and if so what do you think

The number you given is a high compression piston is that correct. I've used standard European ones in 350s with no problems but not High Comp.

Disregard my last post I was confusing. I was meaning 500s not 350s. I've only used the standard European replacement pistons in 500s not 350s. Too much Ale for lunch.

I haven't used this piston but if you're wanting to know what is the reason for the lack of a slot at the front it's for additional strength. The slot was originally intended to allow the piston to flex to reduce "piston slap" which is the noise made by a cold engine. The downside is the piston is weaker which is why you usually only find the slot on low comp pistons. REgards, Mark

I believe this is the piston I put in a Super Star that I rebuilt a few months ago, bike goes exceptionally well, really surprised me, I then fitted a close ratio gear set in it and the owner is really happy with it. I have ridden behind him and I'm impressed with the performance from a 350.

I've put this piston in a couple of machines and it has proven to be excellent. Sturdy and nicely finished and the extra 1.5 atmospheres really makes a difference with the rest of the breathing sorted out.
