First a little background. Bought bike Aug 2010. It only has 9800 miles. It ran fine until one day it would not start. It did smoke/burn oil when I let off of the throttle. Found the no start to be because of only 30 psi compression. It went up to 90 psi after adding a little oil in spark plug hole. I have took the top end apart taking some photo’s as I went. Here is what I have found so far. Let me know what you think. Valves: 1 intake and 1 exhaust seat leaking and other 2 very small seep leak. Looked like 1 intake valve guide leaked. Should I just replace all valves and guides since it is a ’93 or should I just have the valve seats ground so they do not leak? Decompression pin: I think it is stuck down? My manual shows it sticking out a lot. Since it was sticking out just a little I push it down, thinking it would spring back up, and it stayed there. The manual also states not to loose it, like it will fall out. Cam/ timing chain. The cam lopes are in limits. Cam looks good. I think the timing chain is stretched. Look at photo’s, what do you think? The timing chain rides high on cam gear. When I pulled up on chain at gear it did move up a little. Also someone stated on this site that when the hole in timing chain tensioner is not straight up then the chain is stretched. Mine is about 30 deg from top (see photo). Head: It looks like it got hot at one time or do you just think that is blow by? Piston: it looks good. It is stamped MN9 on side it has a stamp HF1. This is the standard Honda piston correct? Piston rings: worn—out of limits. Top ring end gap is .057in. (4X limit) and second ring end gag is .051in (more then 2X limit). Cylinder: it looks good and only has one small scratch that I can fill. I plan to have the cylinder checked for out of round and check cylinder to piston cap. If good just have cylinder hone and new set of rings. I’m not planning on any power upgrades just repair and fix anything that is worn so I will not need to go back into it for a long time. This should keep the cost down also. Is it best to go back in with Honda parts or should I use something else?
