a quick one on fork oil....

[Dappa D]

im just under 14st... ride a 2000 curvey...only changing the front fork oil...

is 15w the way to go?

ps..tried search, if anyone can tell me how to search multiple words that would be good as put "fork oil" just brings up fork, put "fork and oil" or "fork & oil" or "fork+oil" same thing....

thanks

At 14 stone you'll be rather heavier than the stock springs are designed for. I just put clean, fresh 10 weight oil on mine, seems fine so far.

fork+oil would be the way to go but words of less than 4 characters are discounted. Try fork+setup or similar...

Edit: use the advanced search and accept results only from "SV Talk, tuning & tweaking" and possibly "Bike talk" if you're after an answer to a tech question.

Automatic transmission fluid is around the same viscosity and would also be suitable if you want something around SAE 10W.

as standard is 10w im going to put in 15w and see how that feels....

can anyone recommend an amount or should i stick with standard amount???

[21QUEST]

Dappa D, without getting technical, with regards to the numbers on bottle(ie 10w, 15w etc), my advice IMHO is, don't use 15wt . Stick a 10wt in there. It will work better....especially if you do ride in the cold/winter ;)

Make sure you tell them, that you want the air gap, set in the proper manner. A lot of shops just stick in the amount listed in the manual and don't actually check the air gap......

EDIT: do you know what brand of fork oil, the shop would be using?

Hi Ben,

yes mate use it all year round for work, basically the mechanic at the garage will be doing it, hes not a specialist suspension tuner, I cant afford that aswell as the other stuff i need done,

but he can change the fork oil no problem, he has asked me what weight i want in there and what amount i want in there (if different to standard).....by putting in a certain amount in (what amount?) will this automatically make an air gap?..my knowleage is carp on this subject im afraid....

oh and ill be keeping the standard springs for the foreseeable future im just trying to make it handle a bit better....any advice appreciated

Edit....i dont know but im sure i could request a certain brand as its not in untill next wednesday.....(not one thats going to jack the price up by loads tho!!!)

Ask him to put the standard amount in and check the air gap properly with a steel rule. a feww cc's of oil more or less makes a big difference to the air gap, which affects the effective spring rate from compressing the air and the spring at close to full compression. He doesn't need to be an expert, just have a ruler.

Dappa,
Re air gap, it'd be easier for me to say, print out the relevant section of work shop manual and hand it to him.

That said a good mechanic should know how to set the air gap, the correct manner. All he/she needs, is air gap numbers.

Ask him what fork oil they use in the work shop. I don't want to complicate matters(ie thread) unnecessarily but if you post what brand, it might be beneficial too :)

Wish it was that simple......we'd all be errr :o ;)


Ben

[Dappa D]

right then so general advice would be ....

put 10w oil in..

(i dont know much about oil but as this is already whats in there as standard i guess oil deteriates over time so new oil even tho the same weight will feel better?)


put in the amount in ml? cc? thats standard (says in the haynes not got to hand but can look later) and make sure he gets the amount spot on so the air gap is correct?

preffered brand??....

think thats right? right?....

i am confused tho i hear of people saying put heavyier fork oil in all the time on this forum.....

[Dappa D]

was typing while u were ben ill find out mate....

the only manual i have is the haynes....

[21QUEST]

I just fully compress the forks, fill it to the top, bleed the them(pumping them slowly) and then measure the air gap(jambos post). Then do other leg.

Don't worry too much about 'prefered' brand per se....just find out what brand , the shop uses and post it here.....more than like, be well within standard spec(either side of it) but good to know.

I use Hyperpro 15w with Hyperpro progressive springs, similar weight to you.

cheers DD...money is very tight at the moment, further down the line planning on getting the hyperpro kit (springs/oil) from twinshack but has to wait at the moment so just changing the oil....still not 100 percent sure what viscocity oil to use with the standard spring....15 or 10...

Ben/jambo, spoke to garage they use rock oil....also said about the airgap...he said he wont just top up the standard amount as some may be left in when he bleeds them so he always goes by the airgap not the amount put in so sounds good....

he did say rock oil not top of the range or bottom od the range but good enough...
