I recently went through my carbs again because the regular orings I used on the fuel inlet seats failed. As most of you guys know Yamaha will only sell you the needle, seat, and oring as a set for not cheap each. I went ahead and ordered proper viton orings but had to buy bulk and wait. I finally got them in and installed and confirm the fit is excellent so I'm offering them in sets of 4. Selling sets for 10$USD stateside and 11$USD to mail to England. Paypal preferred
That was strange as I went to our local Seal supplier who are 20km (12 miles) away from where I live and they will sell you however many you want.
I discovered afterwards that a bearing supplier 5km (3Miles) from me would have got them for me also in packs of 5, 10 or 20.
The fellow in the bearing suppliers was really helpful and informative and gave me this information
Viton®, Dai-El and Technoflon are brand names for FPM polymers also called FKM. All of the designations stand for one single base material, which is fluoro rubber.
This has two standards associated with it
FPM is the ISO designation and FKM is the ASTM designation. ISO is the International Organization for Standardization
ASTM is the American Society for Testing and Materials
They have a term called shore hardness associated with the seal and medium Hardness is 80 which is best for use in the carbs.
Were these o-rings replaced during Mike’s ivanising days as part of the work?
I don't believe it was part of Mikes brief at the time. The O rings failure is starting to become more and more of an issue now due to the age of the bikes and lack of use with many. The ethanol content in the fuel nowadays doesn't help in the failure of old O rings either
Thanks Unfazed. Mike did my Slip On kit and the carbs haven’t been off since despite winter lay ups. Always try and use Esso 99 and some Stabil during these periods. Drained the tank last year and didn’t get any water out which was a relief.
This place sells them in whatever quantity you need:

Don't take this the wrong way, but I doubt no-one on here is going to buy from a new member, especially from USA.
We're having a reoccurring issue with scammers on F/Book Fazer group claiming to be in the USA.
We can source any bike components in the UK. :thumbup
