|   Shiver DC oil level - info and general rambling on... | klein444
Dec 9, 2003 3:33 PM | | Did a post a few days ago asking about oil level for 195lb rider.
klein444 "03 Shiver - help with oil level & understanding tech..." 12/3/03 1:38pm
Thanks for all the info - I wanted to share what the final numbers were:
Marzocchi: Tech email 85 from top of slider
Marzocchi: Phone call to them "...65 from top of stanchion tube..."
Marzocchi: Phone call #2 to different tech guy "..75mm from top of slider"
Marzocchi: Tech info on website 75mm from top of slider
I asked each tech guy what the distance from the top of the slider down to the top of the stanchion would be (so I could subtract that number from the 'top of outer tube' responses and get a 'from top of stanchion' number) one said it was 20mm and the other 15mm. Consider this then take 15mm-20mm away from any 'top of slider measurements and I get 55-65mm from top of stanchion.
Responses to post:
...about 62mm with heavy springs from top of stanchion
...65mm from top of stanchion, 80mm from top of OUTER TUBE
...60-80 from top of outer tube. med springs = 60mm range w/heavy springs 80mm
Seems like 60mm-65mm will be a good starting range. At this point I have too much time on my hands :P
I think I'll go with the 65mm from top of stanchion.
Guess I really don't have a question. I just wanted to post this so it would help with future searches on the topic.
Thanks again!

| the problem is that there is no set oil level for your weight | Jm_
Dec 9, 2003 4:10 PM | | because the oil level should be ajusted so as to prevent bottoming if you have the correct springs. This means you start at the minimum suggested oil level, and if you are bottoming you add a few mm of oil, if you have the correct springs and for some reason the fork is not getting all the travel(too progressive), then take out 5-10mm, but that is a rare situation. The point is that the fork will work just fine, and the oil level has a profound impact on the progressiveness on the fork.
You get the correct springs for your weight, verify you have the correct sag(if not, you probably don't have the right springs) and then add oil untill it doesn't bottom. If it doesn't bottom with the stock setting, fine, but that usually doesn't work for most people, they usually have to add a little oil, that way marzochi forks can be "softer" than their counterparts, and still not bottom out. |
| the problem is that there is no set oil level for your weight | shiver me timbers
Dec 9, 2003 5:28 PM | | I am 215 have a med spring 7.5 wt oil 75 from the top. Works like a champ |
| theres no way those are medium springs.... | zedro
Dec 9, 2003 5:46 PM | | i'm 165lbs geared up and ride a firm and medium spring kit with about the same oil height. You'd be running way too much sag regardless if you bottom out. |
| Meduim or Heavy springs come stock?.... | klein444
Dec 10, 2003 10:37 AM | | I saw a post awhile back that said Heavy Springs were stock in 03 shivers.
The tech guys at Marzocchi said medium springs.
Anyone know?

| nobody knows!!! | zedro
Dec 10, 2003 12:29 PM | | my bud who got an '03 Shiver with heavy springs, but i dont know if he ordered it like that. |
| Picking bike up nxt Monday - Guess I'll find out then | klein444
Dec 10, 2003 5:29 PM | | Thanks - I'll check sag when I pick up the bike. I have read that there is no color coding so I'll just see how it sits & rides.
I went with the 65mm from top of stanchion measurement for my LBS to check/add to.
Seem like if it is medium springs I'll need that level and if they turn out to be heavy springs I may need to remove a little .
Anyway I am very psyched about the new ride - it has been a long time coming.

Dec 11, 2003 9:55 AM | | Hmm, I installed a 2004 Shiver and bottomed it hardcore the first ride. I'm 160 lbs. Went and bought some 10wt oil, added some to each leg (with stock 7.5wt) and now it's perfect. I'm not exactly sure how much I added. It was 5 caps of "Shock Nectar" 10wt to each leg. I think I just got lucky, but I feel the pain of not knowing how much you're supposed to have in there. What do I do when I need to change the oil? Grrr, salt to taste I guess. |
| RE: What to do when it is time to change oil... | klein444
Dec 11, 2003 10:46 AM | | I bet we could do some calcualtions to try and determine what viscosity you have with 5 capfulls of 10wt mixed with 7.5 etc...
Better off maybe in measuring the oil height as described above (seems the from top of stanchion tube is most accurate) that you are at now before you drain the fork then when changing oil add back to that level. as for what weight oil to use - I would probably go with the 7.5 stock since I doubt your adding the 10wt has changed the overall oil make up that much.
