[QUOTE="Stringer, post: 177561, member: 2086"] I was able to get ahold of that permatex copper spray-a-gasket so I'll give it a shot. I went ahead and scuffed up the bore with the spring loaded hone and mobil 1 oil. Just a few passes, looks pretty good. The pro-x piston kit came in, along with a new wrist pin needle bearing. The piston kit was missing the circlips, and I refuse to use the old ones so I'll have to call around tomorrow and see if I can get them locally. Wrist pin is 18mm. Fuckers. I soaked up the gas/oil mix that was settled at the bottom of the crankcase by operating the crank and soaking up what stuck to the crank using shop rags. Got it dry as I could and began "flushing it, sorta" by adding PJ1 Silverfire 2T oil to the crank, operated crank, soaked everything up, and repeated about 6 times. I left it lubed up pretty good. I got all gasket surfaces prepped really well. Studs cleaned with solvent, mild brass wire brush, scrubdown, and WD-40 wiped on. Cleaned up lower crankcase coolant paths (which end there) with solvent and tons of q-tips. Cylinder, cylinder head, and powervalve assemblies are ultra clean. Got an entire engine gasket kit ready to go, along with some high quality torque wrenches. Im feeling more confident now. Just need those circlips now, and front brake rotor and master cylinder rebuild kit comes Thursday. New radiators come tomorrow. Got to figure out how to true wheels while on bike too. Still a lot of work to do, but I have a decent understanding of what to expect, with the exception of the front master cylinder rebuild kit. Trying to do as much as I can between working, and got a super busy day tomorrow. Lots of new little parts laying around that need to be installed. But everyday im able to get something accomplished with it, which is good! I wouldn't have been able to do any of this without all this help! Can't tell you how much I appreciate it! :) [/QUOTE]
