I hate to rain on your parade, but with all the work and expense you went through rebuilding your engine, you really should have put in a clean oil filter before you fired up the engine. It is always possible that some debris from the previous damage could have gotten loose and damaged your new engine during start-up. Also, as a former toolmaker, we always had a joke about ordering an aluminum magnet. Aluminum is a non-ferrous metal meaning it won’t stick to a magnet. Hoping you have a good test run tomorrow, but please put a new filter in before you go. Ross Lindberg Fertile, MN [b]From:[/b]

[b]Subject:[/b] [DSN_KLR650] Re: Balancer system removal - Got Fire Well I've got it going. This afternoon I put on the cooling system plumbing (exisiting Thermo-Bob user), the exhaust header, and after performing the $0.22 mod and checking the floats, I installed the carb.
I ran the engine for a short period of time and until the oil smoke stopped and I didn't hear the previous gear grinding noises. I drained the oil and looked for metal flakes like I was panning for gold. A few aluminum flakes but not many.
I refilled and ran it again up to temperature with some throttle blips. Again, no gear grinding noises. This time, I shifted up and back down through the gears several times with ease and again without any odd noises. I drained it out again and it was pretty clean but then I pulled the filter and there was more than a few aluminum flakes in that (checked with a magnet). I have to admit, this filter was the one that was in there when I pulled the engine apart, so that aluminum could have been there from the bad old days of grinding noises.
Now it is reloaded with new oil and a new filter but I'll leave it until tomorrow. Enough fun for one afternoon. If tomorrow's test run ends up filling the filter full of aluminum flakes then I have rethink what I thought was success.

system, or carb on it yet. Last night I filled it up with oil and used the starter to pump oil through the system. I'll repeat that over the next few days to make sure everything is wet that should be wet - input shaft in the gear box is hollow and oil comes out several ports to lube the gears. I'll have another opportunity to work on it Thursday afternoon. I should be able to run the engine (without counter-shaft sprocket, chain, rear wheel anchored in place) by then. Hopefully no more grinding noises from the gear box.

boss got the snap ring I needed for the end of the tranny's output shaft (gets covered by the clutch) while the mechanic got out the special wrench to hold the clutch basket and his torque wrench. After I installed the snap ring, the mechanic and I tightened the clutch basket nut to 95 lb-ft (lb-ft still doesn't roll of the end of my tongue but I guess it s more proper than ft-lbs). Walked out with an $11 bill for several snap rings (counter-balance shafts) and free shop time.

off - might not matter), and the cover. Also put the oil screen back in and a new gasket (heavily greased the water pump seal). Finished off the water pump and then put the engine back in the frame after I greased the rear wheel bearings and re-installed the wheel that was off while I installed grease fittings on the rear suspension parts.

After 3 hours of working with what seemed like a Chinese wood block puzzle, we got it running as badly as it was running before he took everything apart, so I guess that was an accomplishment - running again.
