Quote:Are the fork seals rubber?

If so make sure you use proper red rubber grease.

Ordinary HMP grease with attack rubber and cause it to swell and cease to seal.

I had a rubber bush on my VFR swell by at least 25% because the previous owner greased it.

There are a lot of greases out there for specific purposes.
 

 

So if I put HMP grease on something it swells in size.

I can't believe it is so long since I sold my TDM and stopped postinghere.

 

It does have to be rubber so guess if it pleases your wife you won't be involved.

 

Seriously I have recently serviced the rear calliper of my VFR and a rubber guide had swollen by about 25% because of the wrong grease being used. There are different greases for so many uses. I have at least six different types of grease all for different applications.

There is also Alumslip as in copperslip grease for greasing bolts in aluminium. There is also grease for drum brake parts, very high melting point. In short it good to read up what the correct lubricant should be and what damage the wrong one can do.

I got a lot of this info from the VFR site.

The Yamaha service manuals are great for showing the correct grease/loob to use on specific parts. Smile

Thanks Daplep. 

 

Did you mean linkages or have you been through some cow shit and not cleaned the bike?

Hi Guys. Great thread, really useful as I'll be doing a front end refresh over the Christmas break. Going to lube the steering head bearings while I'm at it.

 

What's the opinion on fork oil weight to use on my newly acquired '03 900?

 

I see some use 10wt as recommended others go for 15wt or a mix.

 

Not sure which way to go, and would appreciate some guidance before I go buy the oil.

The best thing about being old is we did all our stupid stuff before the Internet was invented, so there’s no proof.

Sphere.....very personal thing that, I found, depends on your build....errr...weight and riding style and probably a few other factors.

Personally, i've gone from 10wt to 15.....tried a mix (12.5) and gone back to 10 after being told at MoT that " your suspension setup is very hard"

So back to you!!      Good luck!

"10w" pickled onion water is not 10w new oil. So maybe start with 10w and then adjust next time based on a baseline of new oil and not pickled onion water.

As usual Dappers, cut straight to the chase with clear, logical, well thought through advice.

EDIT....no emojis available, but I am winking and smiling....

Thanks for the guidance chaps, I'll go with the std 10wt and see how it feels.

 

I'm not that 'well built' but expect to add a few lbs, consuming cake while fettling. :cake eating:

Be aware that there is no standard for "weight" in fork oils, and different brands' "10W" can vary considerably.

 

Go see this item and the table and comments at the end:- http://www.mototribology.com/articles/su...on-fluids/

 

To compare different weights you should do so within a single brand according to that. Other similar tables are available.
