Well, made a bit of progress on the 4UOregon.
Still on "low budget make it run only" program until my KH400 sells (which at this rate may be months).
- Cleaned the fuel tank and rebuilt petcock. Treated tank interior with Evapo-Rust. Will likely do Caswells later as it's still pretty crusty.
- Cleaned crusty, varnished carbs and replaced all brass with cruzinimage kits. The choke side carb was the worst I've ever seen. Stuck slide and choke plunger. Impossibly crusty emulsion tube and float needle valve.
- Replaced clutch and throttle cables. Pattern throttle cable from Yambits doesn't fit for s#it so ordering a proper one from Norbo.
- Drained and refilled trans with Rotella T4. Old oil looked surprisingly clear, and thankfully no water or sludge.
- Repacked rear wheelbearings, brake arm, etc. Spins nice now. Rear brakes are smooth and goodenough.
- Sourced new AGM battery.
- Found a replacement JDM style turn signal (same as 80-83 XJ550)
- Cleaned, cleaned, cleaned.
Still needs: Complete front end overhaul. New brake lines, rebuilt master and calipers, etc. Forks rebuilt. New tires. Chain/sprox, etc.
I got it to run briefly Friday with carb cleaner sprayed in the cyls and/or carb bellmouths, but it wouldn't run on the carbs alone, so they are back off getting cleaned again.
Lots of stinky white smoke from the clutch side (as anticipated) so engine will come out and get crank rebuilt, new seals and pistons, etc when budget allows. May tune a bit with head skim etc., but maybe not as from what I've heard, head skim makes it fragile, and porting makes it ill mannered for the street (any insight on this would be appreciated).
Anyway. Basically doing what I can and only buying a couple things a week, as this is my slow season at work (real estate home inspector) and money is a bit tight.
Wasting time on 2T forums since the dawn of the internet. RD350LC, TDR250, plated 300XCW. No four strokes.
