I bought Brian Gardner's ST.60 ABC and went over to John Jorden's house to work on my profile. I brought over the liner to show him. While working on my profile John decided to install it. I must say the quality of the liner is outstanding and the workmanship of John was just the same quality.
Only one small addendum. The Rod big end was too small and small hobbyists don't usually have the reamers needed to fit the rod. The fix we used was to use the stock rod.
One other funny thing happened. I needed .038 taken off the baffle and I was looking at John working the mill. I said set it to .038 he look at me and said the HF mill only reads down to 1/16. It just caught me off guard.
Anyway, Thanks to you both.
You should do whatever you need to but, About the piston baffle , IF you have the means to do it, you will be much better off making the head slot deeper and leaving the baffle height as tall as possible, When you do that, The engine makes more power runs better and uses fuel more efficiently
I have made these with taller baffles, also the Super Tiger "COMO" 51 in which Super Tiger upgraded their piston baffle with a higher baffle runs better makes more power than the old 51 and uses less fuel,
When you start trimming the baffle down, you will notice an increase in fuel usage because the smaller the baffle the more fuel blows out the exhaust without being burned
