A bit of a cleanup (down under)

[racerrad8]

So, I did a little more research this morning and learned that Yamaha might have changed the tooth count on the starter gear. I found one source that say this 12R chain works on the 2007 - 2016 XJR1300 engines with 21 tooth count gears. It also indicates the 12R chain is 24 links

Well, that is confusing to me. I have two FJ1200's that are torn down for rebuilding right now and they both have 21 tooth gears. There is a different part number associated for the 07-16 XJR1300. Unfortunately I cannot find a photo of the new part number to count the teeth.

This does shed some light on another issue that cropped up earlier this year and involved a recall of certain XJR1300 engines. The starter chain was rubbing the starter chain oil squirter off. The piece would fall down into the chain & gear and brake the chain.

The wear on the squirter, along with the shorter chain, indicate to me they made the gear smaller which would cause that issue. They also have a different part number for the chain guide. I found one photo which indicates it is thicker which to me also means a smaller gear.

Sorry to hear you got the wrong chain, but I have the 25 link chain you need in stock: Starter Drive Chain

You should also replace the Starter Chain Guide as well.

I learned something new today, now I have to do some more research to get it totally figured out.

Glad to hear I am not going mad Randy ! We never stop learning.

I got the damper elsewhere some time ago (it may have been from you!) so am hoping this is the correct one............(I'll check the wrapping tonight)

I will see how I get on with the supplier before I make alternate plans.

Update:

The supplier of the can chain confirmed that this is a mod that some did on FJ's to give the starter an easier time. He doesn't have any of the correct type so seeing as I was ordering TZ parts from Japan I just got them to add  a chain. They notified me it was shipped Friday so should see it today or tomorrow.

I picked up the rebored cylinder block on Friday night. The work was carried out by one of those old guys that knows what they are doing and has worked on anything that you could mention - steam cranes, turbo props, V8 race engines, go karts you name it. It took me me 2 hours to get away !! A very good contact to know 

Yesterday, after upgrading the puppy proof gate protection and fencing around the yard, I got into scrubbing the bores & degreasing before pressure washing ready for a coat of PJ1 fast satin black. i was gonna cure it in the oven for a while but remembered the wife is on nights at the moment and the "aroma" would have had double consequences !

Tonight I may have a go at painting the cylinder head if the weather holds.

Latest update

I got the bottom end all back together ready for the new pistons.  It had a coat of Fast Black Semi to tidy it up a little.




Last night I began to fit the Wiseco's



You will notice there are only 3 pistons fitted - somewhere I lost a piston pin   So today its shed clean time. I checked with the rebore guy
and he is going to have a look to make sure its not knocking around over there.

So all progress halted for now.

After the clean up and providing the pin doesn't turn up I'm going to look at making an engine stand that will fit into the trolley jack spigot for when I refit it to the chassis. She is after all a heavy heart !

Just for your information. You cannot use the Yamaha wrist pin in the wiseco piston, it is too short.

.....and you can not use a Yamaha wrist pin clip in a Wiseco piston......right Fred?

Jools, I feel your pain, my kit came back minus a couple of bits that stopped assembly. Got them back, but the stoppage is irritating!

I did look at the old Yamaha pins but they all have a very rough line on them either side of the rod so I didn't even offer one up to consider !
There are some on ebay in the USA but the shipping cost more than the pin FCOL!

I'm starting to think that may be the case here too as I never took anything out of the boxes until I put the rings on piston by piston.

I can remember seeing the pins in the small compartment in the box for the first couple but was getting too preoccupied to remember if the last piston had one.

Anyone else had missing bits from Piston kits I wonder ??

[FJools]

Just found a supplier on ebay that is realistic

S278 Pin = US$7.91
Shipping = US$6.93 12 days USPS Int First Class - Compare that with the US$40+ that some robber wanted !!

Hallelujah

What!!?? Sounds like Dick Turpin is flogging bike parts then

[racerrad8]

I'm pretty sure I have them in stock as well.

But they are not on the website for some reason.

I'll have check when I get back to the shop.
