1979 XS1100F Fixer Upper Project Begins.....

Here is the old petcock and the new petcock.

If you are worried about enough gas flow, I run both my XS11's with only one petcock running all 4 carbs and there is always plenty of fuel, even at WOT. Running two with smaller diameter shouldn't be a problem I would think.

Thanks for the info.
It looks like they will work.
After looking closer it's the vaccuum line that is smaller so that shouldn't be a problem. I just hope the angle of the fuel line doesn't hit anything.
Right now I have my engine builder taking the top end off and checking everything out making sure the engine is functional. Plus clean it up inside and then drain all of the old oil and look for any sediment.

Plus while he has the top end off he is going to put a brand new Helicoil insert in to the spark plug thread that is damaged.

So hope fully after that I can finish taking it apart and get everything cleaned up powder coated and painted.

Okay my engine builder took the top end of the engine apart to fix that spark plug and just check the overall condition of the top end.

It was a damn good thing because someone had rigged the cam chain tensioner with a carriage bolt. So it was also a good thing we didn't try to crank it. The cams were completely out of synch and it would have completely blown the engine. The cams were almost in sych with each other they were so far off.

So now I have to find another cam chain tensioner adjuster and a new cam chain since the one in the bike is so loose we can understand why the cams are so far off.

We can't figure out if someone removed the cams and didn't know how to put them back or if they literally jumped to the present positions.

Oh well it can be saved.

Thank God!

Keep in mind that the stock tensioner tends to have the adjuster bolt and lock nut strip out. For this reason, a modification was created to use a carriage bolt with some nuts on it to make an adjuster that is locked into place. DBeardslee I think came up with this one.

It is ALWAYS a good idea to check valve timing and such before first trying to start a bike someone else has worked on. There are so many signs of less than astute people working on the one I have now. But, the timing was correct.

[CKlamer]

The guy I bought this from says he drove it to the storage locker and we really don't believe this bike has run in some time generally because we don't believe it would run because the cams were both almost open at the same time. It was so far off it was scarey. Now the tensioner I was wondering about that because it did look like some one did have a plan of some sorts.

My engine guy said if we couldn't find one he would have to make it work.

But the bike has to have a new cam chain it is just too loose.

Go look in the tech tips, there is a list of all the bikes (and ATVs) that have auto chain tensioners that will fit with little or no modifications. A lot if the to.we you can find one under $10.

A tensioner is not going to be an issue. A bajillion different ones will work. Look here: http://xs11.com/forum/showthread.php?t=35501

Z1 Enterprises has a good chain available.

[CKlamer]

Thanks for the information.
Trying to figure out which of the tensioner part numbers listed is the V-Max almost direct bolt on. Can you supply the part number?

Yeah I have used Z1 on many of my other builds and I bought the chain yesterday with the new master link.

So I hope to have the engine back together in the next few weeks.

I do have the Vetter Vindicator fairing for sale so hopefully someone in the North Alabama, Georgia or maybe Tennessee might want to buy it.

11H-12210-02-00 is the number listed in the tech tip.

[CKlamer]

Okay here is a picture of the cams and where they were sitting when they pulled the cam cover.

You can see how far they were off.

[DGXSER]

I can honestly say I never compared the lobe spacing, what you want is to put the timing mark on the T and then check the dots on the cam to the arrows on the middle cam bearing caps.

[CKlamer]

I myself am not too worried about it I have a professional race engine builder that does all of my engine work so it will be set correctly as soon as I get the new cam chain in.

He did the race engine build on my CB750K Cafe Racer.
He's been building engines for over 25 years for drag racing and AMA.
He specializes in the Hayabusa's but alo does Harley and many other bikes.

Thanks

Okay received this part is and you are saying this works.
It seems to be very different than the stock tensioner.

Has anyone use one of these with good results and is there anything I need to know before trying to install.

Looks like it would be too short compared to the stock part. Plus the stock part has that rubber tip and this one doesn't.

Thanks

Here are the installation instructions for the ACCT...
