Please don't say in the forks : )

To all the member that have changed their fork oil, where did you get it? I have been looking online for vendors that sell the recommended kayaba G10 oil, but searches have been unsuccessful. Should I just go to my dealer to get it?

Also, how much do I need to buy? I know that the oil is measured from the top of the fork when it is fully compressed, so an exact amount is hard to say. That said, when I changed my engine oil for the first time I only bought one bottle of oil, and I would like to avoid making that mistake again.

Any help would be greatly appreciated

Did you try your local shops? They would have it...I gar-Raun-Tee- it...

I used BelRay High Performance 15w when I did my Progressive upgrade...the front end is a new bike...Stock Sucks! For a liter is was $12.00

Does it make sense to just upgrade to Progressive fork springs until I can afford some shocks?

Do the Progressive 412 shocks significantly improve comfort & handling?

Last week I bought about 32 or 33 oz of fork oil from Cycle Gear for about $7. Any bike shop should have it.

You'll need approx 16oz per tube.

Thanks for the info. Now I just need to find the time to do it.

Not trying to sidetrack this thread but I use graduated baby bottles to measure the fork oil.

Simmons, NewBonneville has fork oil, as do many other vendors. Any dealer should have it, and any reputable brand should be alright.

If you have a Bonneville, it will take a bit less than a liter to do both of them, the spec is 484ml each, but you actually set it by measuring the air space from the top of the tube to the top of the oil with no springs and spacers in it, while fully compressed. 120mm is the stock spec, although some people go lower when they replace springs, up to 150mm.

If you're removing the fork tubes to do this, you should consider dropping in a pair of Hagon springs, which are the same length as the stockers (and therefore will use the same spacer) and provide a big improvement. Bellacorse has them, and there is an excellent illustrated guide to doing it (by Keef) elsewhere on this site.

It would be helpful if your year and model of motorcycle were somewhere in your heading or signature.

do not up the wt. of the oil in these forks, unless you are putting valves and linear springs in them they are already Over Dampened, from the factory and this only makes it worse. Order sonic springs for the sv-650 suzuki from the following wt. table then cut the spacers level with the tops of the fork tubes, as a starting point, you may have to shorten them a little more to get the correct sag. The good thing about going this route is that you can do cartridge emulators and you will have the correct springs already.

Anyone ever just siphon out the fork oil out of the fork tubes for a spring swap out?

Was wondering if anyone did and if so, what was used?

Just by looking at it I see i have to take off the wheel, front fender, front fender struts and the brake caliper.

I would rather not do all that. I am lazy

Yes I used the search function but this didn't really come up.
