Hello again, another update on the Saito CR increase and some more ''swiss cheesing''.. Recently bought a Saito .72 GK in good shape and as usual I could not resist to take it apart for a closer inspection. Everything was in good order except that it was equipped with the early plastic rear crankcase cover which is rather flimsy. So I bought a new reinforced cover and gave my usual ''swiss cheese'' treatment and milling of the crankcase to take off 0.8mm for an increase in CR.
This time I went a bit further in my lightening of the conrod. I drilled four holes each 4.2mm dia. which is more than ever before..[X(]....!! See pic of the setup and wish me luck, testing it very soon...Thank you..!
