Due to sad but unavoidable circumstances I have been off track for a while. Eventually I did collect myself and did a reenergizing 3 days in Cala`s shop. Finished the surfaces on the heads successflully, designed new valve guides with some minor changes and adapted to the original style tins, departed from the idea of having the guides holding the tins, but improved the guide for locating the tin and bottom spring washer. Completely rebuilt the crank, new shafts all three, Remains to install guides, machine seat recesses, install seats and do a slight hone in the pair of cylinders with Ross pistons this time. Good news is that the Racestar organization invites to an event last weekend in September on the the new track Tierp. I will do everything possible to be there with a serious intent to nail the single digit.
