TOPIC:

It is not getting any better.
It seems that everything from the cam chain is worn.



The tensioner is done and I guess the roller will look the same.
And why are these part so expensive compared to the rest of the bike?
Probably better to also put in a new chain?

Its pretty common to have the cam chain components be pretty worn. Replacing the cam chain is probably not a bad idea but that requires splitting the cases. you can measure your cam chain and see if its within spec before you decide to do that. The only reason I can see that these parts are so expensive is they have pretty small tolerances, and precision machining of a complex part is not cheap. Also I would replace the little rubber blocks that hold the rollers and such in place. They are likely really hard and can prevent the cylinders or head from sealing all the way if you reuse them.

I do a quick shopping list
The two Idler Assy sprockets are the expensive part of all needed parts

Price for Germany and Netherlands = 887,15 EURO



Price for Isle of Man = 745,50 EURO ( no taxes )!!!!

Hi DoctoRot,
I don't want to split the case so I hope the chain is still within limits.
Now i have to find theses limits and how to measure it.
And I am planning to replace all the rubber components because they are all hard and dried out.(and broken )

Scirocco,
You are always fast with finding parts
I also found these parts in Holland but more expensive, luckily I am going to the states again in a week and it still saves me some money when I pick it up there.
But the big money saver is, if I buy the other brand (I think it is Liska) they are not as well damped as the original Kawasaki parts but half the price.

or these from PMC

Anyone has experience with these?

Go for a riveted chain.No splitting the cases.Jan Smit put one in mine and hes been building drag race bikes for years,so,I reckon he knows his onions.Makes no sense spending the money on a new sprocket and not doing the chain as well.False economy.
The bike looks great by the way.

Hi David thanks,
Going to measure the chain tomorrow .
What has Jan Smit done on your engine?
I had not planned doing it myself but the more I read on this forum and the more I take things apart the more I learn.
But now the weather is getting better I want to stop learning and start riding .
How is your bike? last thing I read you where taking it to a dyno.

Eric

Hey Eric
I took my motor to Jan for a rebore and new pistons (Wiseco).He also refreshed the head and fitted a new chain. I had stripped the engine myself and was also planning to rebuild it but he offered to put it together for a very good price,so I went with that.
The bike is up near Heerhugowaard at the moment,at a shop with a dyno. I called last week and its pretty much ready.The carbs are set up and its running good,Im told. The ignition was a bit of a mess so he sorted that. I should be able to collect it this week ( great if this weather continues).Ill do an update when I get it .
I have heard of a place near Zeeland,which has a dyno (closer to you than Heerhugowaard) I can find the name/address if youre interested

David you have PM

yes you have (at least it shows that I send it twice)

Yes! Found it. Reply sent.

OK, I've been gone awhile and I'm sorry this might be a little belated but.....

Where did the hugger fender come from? I'd like to do something similar to my GPZ750 and that almost looks like what I was thinking about.
