    It only has 2500 miles on it, but sat indoors for at least 20 years (otoh water got into the tank rusted lots of holes in it) but having cleaned the carbs the bike is running great- everything else works. I opened up the AF screws a bit and balanced the carbs, doesn't seem like it really wants new jets but I could do it if strongly recommended.

    New tires etc are coming, will clean and regrease all the suspension links when the wheels are off. When I do the fork oil are there any suggested tweaks to viscosity/amount? I did a Nighthawk's suspension a year or 2 ago and the win there was slightly more and thicker than the OEM spec to improve damping and stiffen them a bit... wondering if something like that would be suitable here?

    Sure is nice to work on an almost new 40yr old bike lol; nothing rusted solid or beat to death- just gummy... OTOH that tank is going to be a pest... going for sanding & derusting, metal putty and POR15 and crossing my fingers.

    Good luck on the tank repair, on the plus side, I have seen a few on flea bay, so worst case...

    Not all putty is fuel-resistant. If you are patching a through hole, be sure to check what the label says.

    copy that... got it from POR along with the prep/coating and rust dissolver- so its compatible. Apparently, before curing it can be easily shaped with a wet finger, hoping that I can feather the stuff on the visible portion of the tank.

    getting the new tires on the wheels tomorrow...
