I've had this engine since 2010 just sitting in a box in pieces, I didn't want to build it up until I had the crank I wanted in it and the jug I wanted to use on it and also until I had time to do the port work like I wanted it.
Its coming together now, I got the case cleaned up good, got the rough rolling china bearing out of it and got the new butter smooth 6202 Nachi Japanese main bearings installed, I polished the main journal areas on the crank so that the bearings are tight but press onto crank without a huge amount of force, got new crank seals installed, adjusted spanner nut on clutch spring to give the clutch a tighter hold before coating the spring well with a high quality high tack moly grease.
It will take multiple post here to share all the pix, but I just wanted to show the lower as it was coming together and show the transfers shape and size based on what we see with most all of the engines we're seeing now.
The crank in this engine is a 40mm stroke GenIV crank that I got from Duane/dax last year, very true spinning crank, by far the nicest looking cranks I've seen hands down.
I will need to make some woodruff keys for the crank tomorrow, I have the ones that came out of the old crank that was in this engine but they're to wide for this crank and I don't want to shave them down because then I wont have keys for the other crank which I think is a fairly good one also, but it's a half breed type with a 38mm stroke and the 110mm rod.
So enough with the jabber, here are some pix of the engine lower up to how it sits now.
