Low compression Help!!?

I'm coming kinda late to this. Had the same thing happen to me with the
compression tester adapter. Last time I use a cheap tester on my motor.

Well, like you I was faced with the task of pulling the head, drilling out
the adapter (which I did using a hand drill), inserting a thread insert (use
some kind of high temp permanent thread lock or it will pull out of the
hot motor next time you remove the plug).

I also replaced the valve seals (wound up damaging a seal and had to redo
the head strip down) and the rings (wound up bending a ring and having
bad compression in one cylinder - replaced during second strip down).

Here's what I suggest: fix the hole and button it up. Leave the base
gasket alone. There's a guy on ebay who's dumping head gaskets for
$25 or so (http://cgi.ebay.com/ebaymotors/NOS-...9310944QQptZMotorcyclesQ5fPartsQ5fAccessories).
I'm running one of his and its dry.

Everything seems simple but the tiny details will cost you big time. You
might get it right the first time but its likely there will be something you
miss. It's also likely that with just 18k miles, the bike will run great on the
current rings and valve seals. You can always go back and strip it down
if there's a problem. Just my .02 cents.

BTW, I have some new OEM 550 std. rings for sale if you want (3 sets I
believe).

A year and a half later I finally got the bike running as well as it did just
before I did the compression test. I stuck through it and learned alot but
I would rather avoid the experience.

Thant sounds like good advice. Any reason that you recommend leaving the base gasket alone? I already started taking mine off....


Thanks

Because to get it off you need to remove the cylinders which would open a can of worms.
If you already took off the cylinders then you should replace the base gasket along with
the oval shaped rubber o-rings. I strongly recommend you get someone to help you
put the cylinders back on as its a hard job with one set of hands. Also make sure you
get every last bit of gasket and dirt off the surfaces. I used a utility knife blade to carefully
shave off any bits stuck on. This way she'll be nice and dry for many years. Also apply
a little grease to both side of the gasket. If you need to strip it down again in the next
year, the old gasket will just slide right off and you don't need to go through the whole
cleanup phase which is the most time consuming part IMO.

OK.. I am getting ready to start assembling this thing soon. A couple of the rods that stick up from the block came unscrewed when i took it apart. Is there anything special i should know about putting these back in? anyone know the torque?
Also, are these bolts all reusable or do the yield to torque and need replacing?

Thanks
