If your tank is down to bare metal, then use a torch over the tank to cook it off. Just don't get nuts with prolonged heating or too hot a temp. If it is epoxy primer, it will bubble loose. Or use a high quality chemical paint stripper.

good idea!

Wish i could find that stuff here

Finished off some repairs and some fab work on the rear hoop, full weld on the side stand mount and rearset brackets while figuring out how to deal with the tank issues.

Decided im too cool for practical things like a centerstand and a chainguard. Hacked off a bit more before goin to paint.

...ill probably regret that the next time i need to pull the rear wheel or oil the chain

Just get yourself a rear wheel stand. You can mount some spools on the swingarm.

Continued trimming a bit more fat off the frame. Reassembled valves and tappets.

Rims off to powder coat. Bearings and brake rotor bolts succumbed to a BFH

have to source a kawi bolt-pattern sprocket

The engine paint came out nice on the crankcase. Any internal engine upgrades in the works?

thanks, its starting to look a bit more presentable now. No engine "upgrades" other than a 601 big bore kit and and an oil cooler (temps and traffic here demand it) . I just wanna get this thing running and on the road at this point

601 sounds like the Wiseco. No replacement for displacement.

That's right. The Wiseco is sub 600 but higher compression.

I think the cruzinimage kit will work just fine. There are many members who have used it. To get the best out of a bore kit, and while you have the engine apart, a port job is a great upgrade to improve A/F flow. Also, this is a good opportunity to check the condition of your valves -- you can lap them -- and valve seals.

yup did a lap job when i changed out the valve seals. Figured porting might have to wait till i have a bit more experience, id hate to screw it up with some over-eager grinding.

That's a prudent choice. I'm told that removing too much material can also decrease performance.

Forks are rebuilt. Couldnt save the old fork tubes. Went with cyclex replacements and kept the front end stock to avoid further "upgrade fever" spreading to the triples, brakes, etc...for now, anyway

Rehab'ed the wheels the bike came with. KZ cast wheels. Touch of straightening and sandblas to clean off the oxidation. Going to powder in pewter or bronze and slapping on sum new bearings.

Nice and clean and straight.

Gotta love sundays. Made some progress today. Overhauled the clutch.

Got my pistons ringed and back on the rods.

And slapped on an 18-tooth front sprocket and a refurbished oil pump.

Coupla questions: should i have somehow primed the pump full with oil before reassembly? And a bit of play on the front sprocket is normal right?
