Spent a few hours with Ken today stripping down my 2100EFI engine to investigate what I knew would be ugly - the last few oil changes on the car have shown some nasties on the mag drain plug and the tappets have been increasingly hard to keep quiet
Head off in about an hour with only a little blood spilled
Cam followers (from Kai Raddicke - Wishboone Classics) looked 'orrible - two were concave
Lobes looked just a buggered - this was a brand new NOS late PI cam from Doug that had been reground to an experimental hybrid profile and tuftrided. I think I committed the sin of fitting super HD springs to cope with the 7500 rev limit I was using. BAD move.......
After about 4 hours spannering we had the cam back in the engine - using a GT42A same as my white PI which was ground in the UK on a new Kent blank. I have managed to acquire and have fitted Clancy cam followers - the original supplier to Triumph. I will be using softer springs... I will try to use Jag but I think the lift of my cam and roller rocker combination will cause coil bind.
