Thanks darksammy,Iv seen you around hear quite a bit so its nice to have a vet peeking in.I have a few ?'s for anyone that can help(well more than a few but still searching threads for the others before asking)first is,from the 4 ultralights i have 2 of them spin alot rougher than i think is normal even considering there not broke in yet,There all assembled the same & the only shims used or needed was the 4 small shims that go in the spider cross shafts.The spiders seem slightly tight/rough at times but nothing a break in wouldn't solve so my issue is with the ring & pinion mesh.Any ideas would be greatly appreciated.Thanks
