No washer gaskets in my kit?

They're not much bigger than 1/4-inch flat washers. Should have been in the Motobins kit but if they've gone AWOL, just cut up your old case gasket using the spots where the screws pass through.

The small gasket/washers do not really seal anything. They act as spacers; same thickness as the case gasket and prevent any bending forces acting on the case cover as it is torqued down.

No need to oil the new gasket. Snowbum says don't put anything on the gasket as its thickness is OEM designed to position the large bearing just so. That said, I used a tiny dab of sealant to hold the paper washers 'cause spit didn't work.

May be after the horses have run outta the barn, but I put some reference marks on the bean can mounting tabs and the timing case to help get the can and engine close to timed position.

You're almost home. Press on.      Monte

OK that's what I had come up with too.

I have a couple pieces with the hole part in tact.

Also I did mark the bean can while the horses were still in the barn also took pictures and illustrated it., I just wondered if there was any thing special besides the o-ring?

I can't find a torque specification for the bolts for the timing cover, anywhere in the shop manual .

5 ft/lb, sounds on the safe side, you can always snug them up a bit more if any leakage occurs .

Unless someone else can find a torque in some other manual .

I read on snowbums torque listing "chain cover 5 ft/lbs" my clymer says
"tighten securely" im not experienced enough for that torque values really help.

This thread is full of good information.

I reckon this thread should be in the FAQ section all is said and done.

It's important to make sure they are all tightened to the same value and use a  "logical torque sequence" if there is no torque sequence listed in the manual...

Thanks Justin it just says to tighten them in a cross pattern like the head bolts.

Yes, the oft mentioned "logical torque sequence".  Tightening this way is supposed to reduce the likelihood of warpage.

Ok got it all back together...quadruple checks on everything.
Put the tank on it hooked the battery back up and it started on the second blip of the starter.

I let it warm up then pulled out the timing light.

I only saw 1 "s" mark this time (signs of improvement) and the mark was easy to align.
Rolled it up to 3500 rpm and the "Z" mark was aligned perfectly.

Went for a good ride then hooked up the timing light again and it was still dead on!

Overall the engine is MUCH quieter and smoother the rattle clackle sound is gone completely.

These are my findings :

Tensioner was worn in 2 places one all the way to the metal and was bouncing.

The tensioner spring was 5 mm shorter than the new one.

The chain was almost 3mm longer than the new one.

The rubber guide was like new but I replaced it anyway.

Oh, and my shiney new exhaust nuts look real good!!

Thanks for the help guys!

I'm off for a ride!!!

Being the inquisitive person that I am, plus noticing the number of views and responses to Amp's Timing Chain Noise thread, I did some checking.

As of right now, for 2009, this thread ranks Number 3 in overall views (546) and is Numero Uno (71) in responses. Should any R65org members be contemplating replacing a chain, this thread will get you off to a good start.

It has been really informative.

Without reading it I (as I am assuming others too) would have simply ordered the timing kit, then gone gung-ho into trying to fit the kit only to then discover the drama's with the exhast nuts.

Once ampliflyer converts this into a Wiki article (with pics) it may very well become the authoritative reference for the first-time chain swapper!

Guys I went out for a 3 hour nonstop ride through the prettiest horse country in the nation.

81f low humidity and a pleasant amount of cloud cover.

My bike rolled without hesitation , felt absolutely great.

No leaks at all.

The new tires are feeling great now... the tranny is shifting like clockwork...the engine feels powerful and smooth.
It sounds great ...cool throaty balanced tone.

Makes me feel good!
