Fork oil

[lwinders]

Can someone tell me how much oil is required in each fork on my '83? And what kind of oil do you recomend? I found a thread about forks with progressive springs, but mine has the stock springs.

Should be 10 wt or 15wt if you want it a little stiffer. Put the progressives in and you will love them.

Thank you KIC. Do you know how much to put in each tube?

[utadventure]

I put in Progressives. I agree, you'll love them!

 

I found the 10wt. a little soft but didn't want to go all the way to 15wt. so, I put 7 oz of 15wt. and 6.5 oz of 10wt. and enjoy the ride very much (total 13.5 oz).

 

Big key is to put equal amounts in each.

400cc per tube per the Yamaha service manual. Several years ago a fellow from Toronto experimented by starting out with 380cc and kept adding 5cc and reported that there was a somewhat noticeable difference. Less oil, spongy ride. More oil, stiffer ride.

 

Anyway, the book calls out 400cc or 14.1 Imperial ounces, or13.5 US ounces 10W...
