Only ran for a min. or two. Before I even tried to start it, I checked the dipstick and it took almost a full quart to fill it. the guy I got it from never had a battery in it or a carb for it. The clutch slipped so bad you could hardly start it. but once it started it idled like a champ. Real quite, probley all the sound deadening in it.ever drove thank God! the clutch slipped so bad it would only turn the rear wheel with it up in the air.

Those pix illustrate what I expected you'd find. Guess I failed to explain it adequately in a effort to not write another novel and send a lot of members off to dreamland.:28:

I've gone through a few engines where the inside surfaces of the cases were stained to the point that no solvent would completely remove the brownish tint, ended up having to spend an hour to media blast the "window tint" off. That's using soft media, not glass bead, sand, soda, etc. That probably wasn't necessary, but if an engine rebuild is worthwhile in the first place, it's worth doing right. That usually means very little extra cash. As you can see, simple engines with simple problems/simple fixes and the devil really is in the details. If you do the math on this one, the payback from splitting the cases will be off the chart compared to the extra few hours of work. Instead of "wouldashouldacoulda" you'll be :red70:

P.C. Just an FYI...I meant spin the engine over with fresh oil in the crankcase, post-cleanup. Never try to do this with solvent alone in the sump, you'll risk galling every bearing surface in the motor.

Bob I want to thank you again, you called it right and yes I'm glad I split the cases now I almost didn't but as you can see I would have been sorry if I didn't.
Thanks again,

Grant

Sure looks to me like that oil was "cooked". Kinda like someone let it idle a complete tank out during July Fourth in Phoenix...

Good on ya' Grant. Looking forward to the end project!

Quick up date, I cleaned out the cases today. Wasn't burned on, but like cake frosting firm on the out side but rich and creamy on the inside... It all cleaned up well. there was no sludge in the oil pump or oil passages, but it did have a bent shift rod. and it did have a oil leak where the shift rod comes out the side cover. I think what might have happened is this bike set on the side stand for a lot of yrs. all the thin particles of the oil seperated out, and leaked out the cover. and left behind all the solid's. Just a guess, but if I did it again I should have pulled it apart the first day. You all know how it goes.... One foot nailed to the floor and still going in circles!

Were moving forward again. Last couple of days cleaned everything up, and reasembled it this morning, new gaskets, seals, rings, and straight shifting shaft, plus a few other parts,

Wow! You do good work. Looks like a new engine. How much time and money do you have invested in the overhaul of the engine?

I had a lot of new parts left over from other engs. But you will spend about $160 to $200 on parts, like basic stuff, rings, gaskets, seals, new oil pump, clutch disc's and clutch springs, and new timing compnets. thats if every thing is in fairly good shape. If you but in a bore kit add another $120 If your head needs a valve job, That cost as well. Or If you buy a new aftermarket head, you get what you pay for. It takes longer to clean up everything remove old gaskets and such, and paint, then to put it back together. You can put one together in 3 or 4 hours. :4:

I painted the cyl. with Dupli-color semi-gloss black eng. paint it's suposted to withstand 500+ deg. We'll find out. The covers with Dupli-color silver #1684 there's a couple different silvers but I have the best luck with this one, then I clear them with some clear brake caliper paint. It seems to hold up better then just plain clear.
The paint on the bike is really in pretty good shape and I'm fixing this as a nice driver. So for now I'm going to leave the paint orginal. I got a new headlight bucket for it and a chain guard. cleaned up the old exhaust and put a new guard on it. rechromed the lower forklegs and tailight bracket and rear brake pedel. I'm in "Free Fall" right now.... Thats where you jumped out of the plane and your throwing fistfulls of Money at the parachute trying to get it to OPEN!!! lol

Thanks for the paint tips. I look forward to seeing some update pictures once it's back together. This bike looked rough when it was on Ebay. Nice save!
