Engine assembly questions.

[Ian Williams]

Simon provided lash is not significant do not worry about a little bit of noise as the cam flicks over on the valve springs, this is perfectly normal. It is important however that you check the cam timing, particularly as the face of your gears do not appear to be in line with each other, that in itself is unimportant but the timing is, Paul should have given you figures, adhere to them. The peg hole in the crank case and cam bush are often damaged and are also not a great design as standard, we have talked in the past about improving this, in doing so you should make sure the bush is located fore and aft correctly as this affects your cam timing. I usually plug and re drill both the oil way and location hole so I can dial things in and ensure correct opening/closing, if really enthusiastic and wanting to experiment further you can make a vernier cam wheel from two old gears.
