1987 gsxr1100 cam chain guides

[lowriderade]

Hi all.  I have a horrible feeling I need to change my camchain guides. Is it possible to do it with out having to split the cylinder head and barrels.  

Last time I had to replace the head gasket was a total nightmare due to having wrong o'rings ( it turned out to be an issue with the gasket sets. Yes plural  ). 

Ive took a pic of my chain. It looks like it's rubbing  on something

I know I've got to drop the crank out to do the adjuster guide.

Thanks in advance

The Rear Blade on the tensioner wears more than the others and you need to remove head and block to replace it 

If you have a manual tensioner fitted it may be too tight accelerating the wear

Got the standered auto tensioner. I did check the tension on the chain and it was slack. But after turning the engine over to do the tappets  the chain was tight.

You could try removing and resetting it.....

I couldn't get a tensioner spring so  popped  some washers on the shaft behind the spring  a couple of weeks ago. I didn't want to try pushing it.  I can't remember what the measurements were but I will re measure it with washers. 

I was going to try pushing the tensioner in one click but I don't fancy doing it

I turned the engine off the day before doing this clip. After this clip I turned the engine over by hand to do the tappets. I checked the chain and it was tight.

The front guide can be done after removing the cams. I can guarantee you that it makes contact with the chain 100% of the time, and makes a difference cam timing wise if its there versus not.

I did look at the front guide a few months ago and there was no sign of wear.  Im defiantly going with the tensioner guide being worn.

Yep. Well I'm hoping i can pull the crank down enough to pull the guide out. I realy don't want to split the cylinder head from the barrels .  In the meantime time I'm going to measure the tensioner spring and maybe push it in one click. I'm also looking at another gsxr11 project.  Sadly I need to get my engine done as I don't want to miss any shows

Just measured the spring.  But I can't seem to find what the length should be..it's not in the manual and I can't find it on the net.  Would any of you guys/girls know at all?
