I like the general maintenance day thing. You can cover almost 99% of what your average moto rider needs to do in a days time. Chain/sprocket, fluids, tire removal, spark plugs, valve check, pads, basic suspension setup (maybe), stuff like that.

Not sure if anyone posted it yet but I would sit in on a cylinder head class....Inspection/overhaul/upgrade (Port, polish, valve lap, seal replacement ect.)

As well as Transmission overhaul/upgrade (gear undercutting ect....race shite)

Done some cylinder head work but I like learning new things and I dont have experience with port/polish work yet.

Valve check - I can bring the CRF150Rb. It needs the maintenance anyway.

Valves/Cam/Maybe install a different cam - Perhaps something to try on the WR450? Just a thought. I know very little about the upper end of a four stroke, so this would be interesting.

Carbs - I think a lot of folks are confused about carbs. How to tune them, differences between 2/4 stroke carbs, jetting, pilot circuits, lean vs rich jetting. Having gone through this learning curve on my own I know there is a ton of information out there. But it takes digging to really understand it.

Tires - How to change tires. Dirtbike vs Streetbike. I do dirtbike tires all the time. But I'd rather not do street tires so I don't damage rims. (Like the magnesium ones on my ducati.)

Maybe a basic maintenance class. 2-3 hours, oil changes, chain adjustment, tire pressures, basic suspension setup - sag & clickers explained, setting bike up for rider comfort, simple chassis geometry explained.

Trees - how not to hit them.

^^^ Huge +1 on changing tires. I don't care about scratching my RMZ wheels but I'm definitely not trying to customize my ZX-10 wheels. I know its not hard but seeing it done and being able to ask questions would make it much easier.

Both Todd's 250 XCW-F and Donovan's 150R need valve work, too, and I already offered the 250 to Chris for a demo bike.

Don't forget the car. The older kid broke that I believe.

I don't think Chris wants to undertake rebuilding a car.

Is it still a "top end" rebuild if it is an opposed twin? At least the valve check is quick and easy.

There is a difference between 2 and 4 stroke carbs? Shit, I had no idea. Major difference or just a jetting thing?

Modern 4t carbs have leak jets and AP pumps. They both still have a main, Pilot and needle.

also the 4t has a fuel screw and a 2t has a air screw

And the 2 stroke is generally a bit more finicky with regards to temperatures/air pressure/humidity.

I'll find the pictures I use to help identify tuning issues. (Which circuit is coming into play, etc)
