Thanks for that, 1 Thump !
Here is an update after the track day [Friday] followed by racing on Saturday and Sunday.
Dave and Ian travelled to Anglesey on Thursday evening, after some frantic work to get the 350 running again after it suffered a piston seiziure on Wednesday evening while on the dyno. This machine had a change of cams, piston and a cylinder hone and left home untested, apart from verifying it ran and sounded like it might be 'in the zone' - even the cam timings had been set using felt pen marks and a straight edge and were largely guessed
.
Both 350 and 500 machines ran for the track day, but finished off as non runners. I had my work cut out, but knew I needed to replace a broken cam follower on the 350 - this was done and she was up and running again, but missed out on the first 350 race in the morning [Saturday]. In the second race, Ian thought it tightened up while leading on the last lap and wisely stopped.
The 500 had a bent inlet pushrod and a seized two piece H&C camshaft - this cam has been used for over 5 years with no trouble, but now the bushes had stuck on the cam spindles and the shrunk on ring gear had slipped, causing the stoppage. This is where Ace will start to cringe !! - the cam spindle was removed with a special puller and the seized on bushes were ground off. The cam spindle was knocked back into the crankcase and another, almost identical, but one piece camshaft was fitted, after timing by felt pen and straight edge [as on the 350]. The steel inlet pushrod looked like a letter 'S' and I had no spare of the required length, so I stuck it between a steel upright part of a building and the concrete blockwork and pulled. Same again for the other end and it was straighter than some new Indian ones I have seen. In it went and the engine was soon running again, but there was clutch trouble and we had a 5th place for the first race. I sorted the clutch [another long story] and it raced again, but got a DNF rounding off day 1.
Sunday saw the 350 win both races, but the 500 suffered valve train issues in the first race and ground to a halt with a dislocated pushrod.
A troublesome Ducati 250 scored one 5th place all weekend and was enough of a distraction to make the Cotrell 250 Crusader miss one race altogether, but the little R.E. scored two wins and one second place over the weekend.
There will be spanner work to do before we attend the next meeting at Croft in a month's time
