anyone know what would cause this damageÉ





83 and 85

You're going to want to replace your camshaft as well. Look at the lobes where the damaged rockers were riding. There's probably some scoring going on.

pulled the head and jug today

looks like some corrosion in the cylinder , it still has good cross hatching, should be fine with just a re-hone??

plan on relapping the valves, will i be fine with just new stem seals? or will i need guides too?

My rule of thumb is just spend money where it is needed. A hone, stem seals and maybe a valve job if there is a good shop near by. The guides only need to be replaced if there is play between the valve and the guide.

Petcock Leak

The XL has begun a slow fuel weep at the petcock valve. Is this something that can be typically remedied by installing some new seals or is it the type of valve that you just replace entirely?

Just replace it.

Here is what I would do...

Order a set of OEM HONDA gaskets, dont buy anything other than Honda gaskets.

Take the head apart, keep the hardware together for each cylinder, sandblast the head and the outside of the cylinder, the cylinder looks good, in the manual are the specs for the roundness and the O.D. limit, check those. Obviousley get new rings, and also get a new CAM chain, don't cheap out and re-use it. I would bet for about ~$300 you will be ready to go.

Just my $0.02, let me know if you need any help. O yes...PM me or MCMA111 with any questions, he is the RVFC expert.

Randy,

Before you do anything take the piston and cylinder to a good machinist and have both measured. If the parts pass have the cylinder lightly honed. With the head upside down fill the combustion chamber with solvent and let it sit. Look in the intake and exhaust ports to look for leakage. When you see the leakage (it WILL leak) have a valve job done on the head. Order a set of rings, valve guide seals and the correct OE top end gaskets. Put it all back together and it will run better than it has in years.

That cylinder doesn't look any good to me at all. It looks like someone has been in there with a hone before--doesn't look like factory hone marks to me. That rusty spotting is terrible. I'd be willing to bet a lot of your oil burning issue is because of this.

depends on where its weaping......generaly replace it(im looking for a few "bad" or weaping stock units to see about making replacement seals for)

im defienetely getting a new cam chain, tensioner spring and o ring, stem seals and rings

might get a new cam chain guide if it looks worn out

my guess was that this motor got a new piston and bore a long time ago and hasnt been used much since, it has 175 psi. i have had it since may 2011 but have only ridden it up and down the street a few times... cant wait to get out on it!

i noticed theres three headgaskets stacked when i pulled the head, anyone know whats up with that?

where do you guys buy OEM parts?, i bought from partspitstop.com but it was pretty expensive last time...

The latest cheapest parts place:

Keep tapping the side of the cylinder. It will pop

Randy,

Whatever you do do NOT take a picture of the gaskets that you are describing so that we can all better inform you of what they are, PLEASE DO NOT TAKE ANY PICTURES AND POST THEM HERE...dont do it Randy.

I bet they are Honda gaskets, enless the PO was a moron and put in non Honda gaskets. Also get a ricky stator, stator enless you already have one. Ground that extra green wire to the air box upper frame mount.

-Jack
