Hi all i'm desperately looking for some parts for my newly purchased 1986 fz 400 project restoration bike.
I need to get 3mm valve stem seals 16 in total and compression and oil ring kit for all four cylinders.
Any help will be appreciated and also if you know any site I can purchase them from I would appreciate it thank you.

I think it will depend where you are. I think most of the guys on this site are in the UK.
Sourcing them locally will usually be the best.
Most parts seem to still be available in the USA but the shipping might cost more than the parts.
The valve guide seals are 1WG-12119-00-00 according to
http://www.boats.net/parts/search/Yamah ... parts.html
They also have rings listed, not cheap.

Welcome to the forum, yes piston rings don't come cheap but then again you'll need to do it once. You'll be honing the bores and getting the head / barrels skimmed huh ???

(one thing though 1 post in 1 forum is all it takes )

Hey thanks and thanks for the heads up

Hey is there anywhere else besides boats.net?

Fowlers in Bristol - ring them up but you need to give them your frame number (on the V5 as well as the frame) before they'll serve you.
Make a list and buy it in one hit, you'll save money on postage.

Hey thanks so much sorry for the late response will get to it today.
