I was fortunate enough to be able to be off from work today. Thank God for Christmas!
And as I am wont to do on days off, I managed to steal some time to go into the machine shed to find a few more parts for this project. I pulled out another exhaust, a few primary clutches and a couple of secondary clutches, a radiator and a few other odds and ends.
Checking the primary clutches, it looks like all three have E ramps. One appears to be from a 340 Invader (no weights) and the others appear to be Intruder primarys. I will look again to see if we have some with F ramps. But, I am curious of other's experience with E ramp clutches in a 440 Invader?
