It blew some smoke yesterday when I first started it before I rode it but then it seemed to be clean. I held my hand behind the exhaust for a bit and came up clean.

You're right, only half the plug is black...I didn't notice that.

I didn't check valve height or run the compression check. I'm wondering if I need special tools for that? Going to look it up in the shop manual...

It would be much easier to check the valves if I had the first clue what I was doing, lol.

"Check the clearance by inserting a flat feeler gauge between the rocker arm pad and camshaft lobe"

Great, WTF is that. Off to google I go

Sounds like one of your valves may be mucked up.. Check your compression too.

I've been out there kicking that thing all day, got it to run for 5 seconds once but that was the best.

I did take the valve covers off and looked at the top of the valves. They were very clean looking, no carbon buildup...looked brand new actually.

I need to get a feeler gauge and a flywheel puller before I proceed any further.

Work through one thing at a time. If you skip around to different things it makes it hard to keep everything straight.

Yea I don't say things very well but that's what I was getting at. You need to make sure one thing is "perfect" before moving on to the next problem. Otherwise you can never be sure what the actual problem is.
