New project bike
#21
I'm gonna yank the valve cover when I get back from GA and check things out. At least I have a full set of valves in the old head, but if my suspicions are correct and I do indeed have bent valves, I'll very likely just put another engine in the thing, as they're cheap enough.

Thanks to hamlin6, I have the carb gasket I needed! However, I didn't get back from GA until Friday evening, and had a work emergency yesterday that kept me from working on the bike. I have to leave today for Roanoke, VA. Things should calm down a little by the time I get back from there, so I'll have to time to really look at the situation with the bike.

So, I pulled the carbs last night and shined a light down the intake runners, and was immediately met with bent valves in cylinder #2. Upon closer inspection, it was worse than that. Dropped the engine and pulled the head, and this is what I found:
3 bent valves in cylinder 2, and the other valve had broken the head off and then broke in half. Beat the chamber and the piston up pretty good.
1 bent intake valve in cylinder 4. You can see where it kissed the piston, but it didn't damage it.
The tensioner didn't seem very tight when I pulled it apart - I'm wondering if that's what caused the chain to skip. It seemed tight to feel it, but the cams were way off timing-wise, and there was evidence of the chain rubbing up against the head itself.
The sad part is, I *could* fix this - but it's not worth the time and money. I picked up a replacement engine cheap and I'm picking it up this afternoon.

I know I haven't updated this in a while, but there's not really anything to update. Bike is sitting in the corner in the garage. I actually haven't ridden it but around the parking lot, since I don't have it tagged yet and it needs a rear tire. Plastics will be here next week, but I won't be able to touch them until the weekend because I'll be on a plane to MN Monday morning. When I get back, I'll put the plastics on and upload a pic of the finished product.

Plastics actually came in yesterday!
I started work on them, and so far so good, except that someone had put a 95/96 taillight assembly on the bike (I didn't know the diff), so now my rear fairings won't fit until I source the proper taillight & bracket. Gonna need a 97-98 seat also, apparently they are different as well. Can someone give me a rundown of changes between 95-96 and 97-98?
Here's how she sits with no taillight on one side haha:
