Re: Aluminium heads on singles
We have had heads welded up at Draganfly, Which I think was done after machining a large countersink so that the weld could reach lower down into the hole, not just round the top. We do this when repairing pulled studs on SQ4 heads but have only had to resort to this a couple of times with VH heads,...

Re: 350 bigend torque figure ?
To be honest I don't use a set torque just basically as tight as I can. The limit is reached when the crank flies out of the vice that is holding the crank while you lean on a 2 metre scaffold pole.

Re: 350 bigend torque figure ?
That might be a bit much, the official figure is FT, 60-80 ft lb is sufficient, as long as the taper is good, too tight and you may shatter the wheel

Re: Noisy cam pinions
The cam pinion will very quickly show some signs of wear on a portion of the teeth and wear no more after that, warned Ariel many years ago. The half time pinion does not do this so if yours is showing signs of distress try a new one.
