Piston/barrel dramas

Here's something else, there are two different size clips for the gudgeon pin, 54 thou and 64 thou, the 64thou ones being in the damaged piston and are a smaller 'loose' size
IE they nearly drop into the hole, not bugger all spring tension to make sure they are held in in my mind now either the two pistons have different size clip grooves or the builders simply put some clips in that are fatter than they need be and were never going to fit in the groove...
The broken piece is all that was left of the offending clip

I did come across this little gem in Phil Irvings Tuning for speed. It makes a lot of sense to with regards to the shape of the pin. Clever bloke that Phil.

That is your Google search, internet based assessment ....... Many is the spotty little kid that comes into a workshop, fresh from his education, that soon realises the difference between the theory and experience is massive.

What you say is true, although not nice or very smart.

I have spent a lot of time with Team ESE in the workshop and know my limits but I am smart enough to do some research and join the dots, so in my posts as well as writing about what I have learn t, I like to research and reference other people with real industry experience and something credible to say, if I get stuck and ask, TeeZee or Thomas will always point me in the right direction.

Pictures of TeeZee's 239 hp per liter FZR/GP125 Bucket with a good 3,500rpm power spread, I helped with a lot of the work developing it.
