Unless the seat has failed and come apart you may have dodged the dead piston bullet. Only one way to confirm. Tear down the top end. Black Diamond is the good aftermarket brand of valves and springs.

the engine has excellent compression, I can still stand on the kick starter. I'm looking for the rebuild receipt from the PO to see what all was repaired last time. I'm hoping I just need head work but I don't know too much about rebuilds and all that. I know I need to yank the engine out but I won't have access to a garage for a couple days. I read all kinds of threads about rebuilding 4-stroke engines and it seems my problem isn't anything compared to some of the crap I've read.

I wouldnt get too upset. Used heads are coming up all the time on ebay if you have to go on a shoestring.

On a side note, I cant believe some of the idiots selling obviously broken worthless parts on ebay. Trolling for suckers I guess.

I'm going to go ahead and assume that's bad, then replace it.

Thank you, Steve.

I bought an EBC off eBay with heavier springs for mine. I would forgo the heavy springs next time since effort is also higher. Next opportunity I have to pop the clutch cover the stock springs are going back in.

The clutch works well, no complaints, has a linear feel that was lacking in the original one.

If you got the bike with anticipation of making a profit on it you got the wrong bike. I have been where you are at. I mine to much to give up on it. When you decide to rebuild it, do it right, don't go on the cheap like I did. I have had mine apart three times in the last year. I have almost replaced and or rebuilt the entire engine. Here is a list of the parts: gear shift shaft, Head, 4 kibblewhite valves, all the seals and gaskets, wrist pin, new sleeve (wanted to keep it stock), 2 timing chains, upper and lower timing chain sprockets, both timing chain guides, two sets of rings, 4 head gaskets, 4 valve springs, low speed jet, 2 carburetor kits, clutch plates and fibers, Ricky stator, piston, jug, crankshaft, connecting rod, rockers and cam polished, and the left main bearing. I don't want to jinx myself but she runs pretty damn good now. The only reason I replaced the jug and piston. I wanted a running bike while the new sleeve was being installed. Plus I wanted a spare in case it got screwed up. I was lucky and bought the crankshaft with a never used hotrods connecting rod installed on it for a dollar plus eighteen dollars for shipping of off fleebay.

So the moral of the story do it right the first time and you won't have to worry about it for another thirty years.

The lower timing chain sprocket is no longer available through Honda, if you would like to know what I used just ask and I will tell.

Thats why everyone needs more than one bike. While one is down, the others keep you company. I took time to fix alot of crap with the engine out waiting for the head rebuild. Clutch lever, rear turn signals, carb cleaning, different oil cooler, swing arm bearings. It has been a fun month.

In my opinion this is one of the easiest and very forgiving engine to work on. It's not that hard to work on, all it takes is time and money. Unfortunately time is a lot easier to come by. If you haven't already I would start by getting a Honda shop manual.
