Re: tinkering. Yes, I enjoy tinkering. Getting my CB750L running good last year was fun. Working on the different systems (carbs, electrical, tires, drivetrain, adjusting stuff, upgrading stuff) scratches the engineer in me. Riding scratches me in other areas...mainly in enjoying God's creation, and sharing the 2 finger salute with other motorcyclists.
Same thing happened when I got Avenger II, a 1984 Honda Shadow. Needed LOTS of work on carbs and such, but is running well and returning almost 50mpg. I just found a leaking float bowl gasket on one of the carbs, so this is a good time to pull them apart once more and see if they need cleaning or adjustment.
If you can, upload some pics of your project. We're pretty visually oriented here, and who knows: maybe your project will inspire someone else.
Good luck, and welcome to the forum.
