Inside of the tank is absolutely immaculate! I lucked out with this bike as most half its age have at leaast some rust. It has literally no rust. I wanted to swap out to an older style tank, but the 77,78 tanks are growing on me and may just go with it. It has a few dings and chips but overall is very workable.
I agree with you guys about the pressure washer, but I intend to tear this bike right down and detail everything. I'm relacing the rims with new spokes and an 18" rear wheel, new wheel bearings etc. I know the negatives of pressure washing but the bike was a lot grungier than it looks in that pic. If the water is not shot right at seals, and other obvious sensitive spots, you can get away with it.
It's not idling now so that's the reason I need to get into the carbs. I have a 4-1 exh and would keep the stock system, but it's got large chunks of the chrome flaking off and looks terrible.
