Some of you may know I picked up a '79 R100RT to be my tug for my hack. Before I mount it I want to go through the bike and have it tuned up. I'm still consider myself a noob working on Airheads. So I want to know how you would go about tuning the bike. As for how the bike sits so far, it'll idle but kind of rough. I bought it from a gentalman from Missouri and the bike has been sitting for 2 years. I do notice a leak around the oil pan and oil drain plug so I know I'll have to replace the gasket and o-ring. Lately it's been tough to start, maybe it's cause the tank is almost empty...but when starting it sometimes it'll back fire pretty good. Almost like a gun shot. Also sometimes when trying to start it it'll make a spinning noise like the starter is not catching...i dunno. Can anyone help with trouble shooting with the issues so far?
