Default success on fork oil change?

     

I have an 03 crf 450 that is do for fork oil change. My seals are not leaking. Do your seals hold up to the teardown and reassembly? If the success is low, I will replace the seals. I weigh 175lbs. What weight work best? My ability is upper intermediate. Any help would be appreciated. BERM!!!

You'll be safe. I've had the same seals in mine for two years now and I've had the forks apart a few times. If you pull the seals off the slider just be very carefull when putting them back on. A little oil and a sandwich baggy go a long way here.

I have one. I just put in motorex Racing 5wt fork oil and I love it.

Noticable difference. About $11 a bottle and you'll need 2 if you are doing the inner and outter chamber.

PS. Props to Faded since he's the one that changed the oil for me in mine, and he's the one that told me how much I would need.

I don't recall what stock is, but I went with 390cc's.

The range is something like 360 - 412cc's

Another good fork oil is Mobil-1 ATF Synthetic. Shocknut turned me onto this. It runs about $5.50 a quart and is found at Auto Zone.

The only catch to this fluid is it runs thick. I think he said they were figuring it to be anywhere from 7wt to 10wt.

I did some research lately on the subject, and for twin chambers the hot setup is: Motorex 2.5w inner chamber, and M1 ATF(15w) in spring chamber.

Hmm.. that's interesting. Are you going to go that route?

If you do, let us know how it goes and what you think.

Me?
I sure am gonna try it.
First the M1 Atf is a little bit thick to run in the IC. It has some very good qualities though; like the ability to stay clean and prevent internal wear-exactly what you want in the spring chamber.
For the Inner chamber I was recommended to use Motorex 2.5 because their products are a litle bit thicker than most other in the industry. People who are used to Motorex thicker viscosities usually put the 2.5w in Showa IC and the 5w in Kayabas
It would be hard for me to give a ride report soon. I'll be happy to report what I think of this setup this spring. There is snow everywhere 3' high. Right now I'm riding my sled to survive winter : .
Take care.
J-S

I wouldnt recommend the ss7 to anybody (except the guys I race against...).

I use the HP 5w fork oil and it is a good fluid at a reasonable price. I tried some ss 5 in my shock and it was trash...
