I apologize, all of these pictures are done with my ipod it's all I have :/ Anyway, that was before teardown. Discovered this beautiful looking piston:
Unfortunately the cylinder had been scored, so I hemmed and hawed about it until I finally sent it off to powerseal usa for a replate. $381 later I have this (would have been closer to 320, but they found a crack that needed welding):
Annnnd....
A new wiseco piston :D So I'm super pumped about that. I wish I had done a before and after of the cylinder, it blew me away when it arrived and looked brand new!
I still need to order some parts to get going. I was planning to remove the engine and get the crank seals done as I believe they are leaking a tiny bit, but I've run out of money at this point. During my struggle to get the engine out I had to saw the swingarm pivot bolt off, here's the result:
Bearing had seized to the bolt, what a pain that was to remove! Took me a few days of cursing and trying different methods, but I finally prevailed.
This is the left exhaust valve, three of the teeth have stripped so that needs to be replaced. The right side one is fine, so that's good. I have a question about the center valve, it has two teeth on it that look shorter than the others, almost as if they had been stripped but the edges are smooth, unlike the broken teeth of the left powervalve which are sharp. Here's a picture:
Is it supposed to be this way? From what I can tell the powervalve rod never even reaches this spot?
Two more questions and I think that's it for now, phew! Do these reeds look ok? Probably hard to tell from the pictures, but there's no cracking or splintering anywhere, just looks like one side has burn marks on it?
And finally, the kickstarter was giving me troubles when I was last trying to troubleshoot the bike last summer. It wouldn't catch all the time, so I'd have to kick and kick and kick slowly until it finally caught, sometimes only giving me half of the stroke to try and kick it over. I expected some of the teeth were stripped but when I got everything apart it looked just fine. I had read this could be related to the spring, should I go ahead and try replacing this?
Wow, long first post! Thanks in advance to anyone that can help me out with my questions. All advice is appreciated! Looking forward to getting into the woods this summer, it's been too long since I've spent some time on a dirtbike (hmm, 10 years now?) wow!
