[QUOTE="davidd, post: 116635, member: 1177"] This past weekend Scott Dell and David Tompkins raced at Laguna Seca. There were quite a few mechanical surprises. Because the "off season" was so short Scott did not get a chance to finish his engine rebuild. He used David's first engine which had become a spare engine when. David fitted an engine I built for him last year. Unfortunately all those small fitting details caused issues. Despite the issues Scott came in 3rd place on Saturday. On Sunday he suffered a DNF when the exhaust nut popped out. I suspect this happened because Scott's exhaust nut was a bit small and the threads on David's heads were a bit large. This is not an unusual occurrence. It is best to use an oversize nut, but when your exhaust system is already built you would not be able to test the fit easily. [ATTACH type="full"]32374[/ATTACH] David had a problem with his aluminum tank leaking. It has had about a half dozen breaks over the years. Aluminum tanks require some special construction on a racer. Fortunately, he got som Seal-All, which is excellent stuff. David wiped some on the leaking crack directly and it held for the entire weekend. David had two 2nd place finishes. David had the new taper roller steering head he built in place. I had urged him to go to a coil over on the front and it was good to hear that he felt it was a definite improvement. [ATTACH type="full"]32375[/ATTACH] A long way to go for a race weekend, but it is a great track with a lot of history! David [/QUOTE]
