Project Joker's Angry Fizzer 400

I just remembered I had the same issue Stu, when I ordered my 400 Gasket kit I noticed the seals were those brown and metal ones where as the OEM ones are green viton so I had to order a separate set of stem seals and to this day have a set of the brown ones doing nothing

Hmmm what a pain in the rear. I'll try the 250 ones on there because they seem to fit fine. The seller says the 250 and 400 ones are the same so here's hoping.

 

Already checked, seller said they're exactly the same.

 

Seller it talking out of their behind - FZR250 part 3LN-12119-00
https://www.fowlersparts.co.uk/parts/view/3LN-12119-00
Nowhere does it list an FZR400 as compatible with the 250 part number

Sounds like you've copped the "same same" attitude

 

For the 2KR Stem size is nominal 4mm (3.975 intake 3.960 exhaust), it was reduced to nominal 3.5mm for 3LN series (3.475 intake 3.460 exhaust)

So you could hypothetically stuff a 4.5mm stem through a 3.5mm seal, not worth doing however

 

Yep... goop gets into everything.



Glad all that is cleaned out. Engine is coming together now:



Starting to replace all the gaskets from the kit while I'm at it, clean the goop off. Some donkey used clear silicone around the oil filter cover what a pain that is. Glad wemoto has so many parts available including the o-ring for a few bucks. So much easier to get parts than the 250.

Also... Is something missing from the clutch pressure plate here i wonder...?

 

Figured out yesterday I need 37nM for the head bolts... my wrench only goes up to 22 so a new one is on the way.

 

Yeh that's what I have. New one was only $50 figured I may as well invest.

 

Guess what im doing this weekend...? Everything's here now, getting very close... (wow the amount of times I've said that, I must own FZR's)...

 

Yep got all those for the other torque wrench so all set. Will hopefully have the timing set up tonight ready to put the engine back in tomorrow!

 

Might seem a silly question, but the timing marks on the cams (the little dots) to they align on the magneto or the clutch side...? The FZR250 is opposite, t mark one side timing dots the other but according to this it looks like same side:



Damn I can't remember. @maelstrom with your 400 would you know please? surely they're opposite sides like the 250...?

The second photo down appears to shown the marks lining up above the magneto which is the same side as the T-mark.

 

No they seem transferable both ways. I've sussed out what I can and I believe the marks are the same side as the magneto... seems to line up correctly.

 

Second photo shows the timing marks on the LHS - that's the inlet tracts visible in the upper portion of shot above the gasket edge and the exhaust studs visible in the lower part of shot below the gasket edge.

All three photos in that sequence are from the same directions/orientation
