GR650 Fork Spring and Oil Replacement

[mnferwerda]

I used Mike'sXS emulators on my GR650 and they work well. The front now feels planted.

After putting it all back together, I put in a layer of grease on top of the stopper that covers the circlip, because you will be back in again sometime.

Kind of late on this but, when replacing the springs what additional parts would you recomend buying ahead of time, seals O-rings ect. If I go with Sonic springs what other parts should I have on have on had so it could be finished all at once.

Depends on condition/mileage of the bike.

Are the seals leaking at all right now? How many miles on the bike?

[DrDankNuggs]

Pretty low miles 8,500 was found at estate sale, no damage anywhere aside from damage to chrome from rust, but drained less than a ounce out and it was pretty dark no leaks though, although there was no air in them so adding air my expose a leak.

Well, the oil went somewhere.

i'd order seals and do them at the same time. Are the fork tubes pitted at all?

No pitting, but I should have Clarified, I only drained less than a ounce out to check the condition of the oil, there was more that would have come out if I had allowed it. didn't want to drain fully until I had all the proper parts in hand to complete the job. I put some air in there and that did help quite a bit, as of last night didn't appear to be any leaking.

If the seals aren't leaking then no good reason to replace them. Just do springs and oil. No air with the new springs.

Perfect thanks for the help Rich, last thing which spring set would you recommend for a 6'3" 230 guy.?

[RichDesmond]

I’d go with 0.90 springs and 10w fork oil.

I’ve been using Yamaha brand oil lately because it’s available at the Yamaha shop close to my house and relatively cheap and I like supporting local businesses.
