Looks like they are Danny.
Did not notice the holes on the piston facing the back when they should be to the front.
Doesn’t matter as it’s going to be stripped down and new pistons fitted

Is Mick Abbey the person who is going to build the pipes & set it up afterwards?

Re: 300cc Kr1s Engine build
What I meant about the pipes janbros was that the pipes are being made by mick abbey who is tuning the top end. And then setting it up on the dyno.
That’s why I said it will be the first time it would of been done,
I know you and fred have made pipes before, so may of got it a bit wrong.

Thanks for the link Danny.
I have found one bearing that may do it from the list you sent. Would be easier than fitting washers.

Re: 300cc Kr1s Engine build
E3 plugs ,aren’t they the plugs with the fancy electrodes, bit like marine plugs? Looks like everything on your sparks from generation, timing, connection and firing will be spot on. Looking forward to hearing how its going.

Hi Steve,
Been running mine with all those parts for over 4 years now, never missed a beat, never fouled a plug in all that time, and had quite a few blasts on Mick Abbeys dyno.
Cheers

Re: 300cc Kr1s Engine build
I didnt spot the electrical wizardry you had employed in your build Bernie. I guess I looked more at the finishing and those lovely Lomas pipes.

I'm not sure whether V-Force actually list those stuffers, Scooble, but BDK certainly do!

I wonder what the bore is of these cylinders- 60-61 mm?
