After reading the preceeding post about fork oil and levels I phoned my local Suzuki shop to ask them about 81 GS850G levels as my manual mentions only 8.5oz. The tech found the factory manual, looked diligently at it while I was on the phone and said his book only mentions the 8.5oz as well. It did mention using a special tool (suction) but gave no measurement that he could find. Does anybody have this info out there?
Thanks, Bob
 
Its in there...although he tried he didn`t look at the correct place. I`m sorry I have no info on your bike. Measuring the oil from the top is the only accurate way to do it. I simply take a flashlight and a small ruler to measure mine. Do remove the springs and compress the forks...I pump them up and down several times to make sure I have all the old fluid out and then do the same when refilling. Good Luck!
 
For US types (80 GS850GT), my manual says 251 cc's (sorry, but you'll have to recalculate to oz) or 140 mm measured from the top (160 mm for GLT).
 
Thank you

Thank you

OK, the tech did have this information after all, he just didn't know it. On my piece of scrap paper I have 140ml (maybe he said mm and I missed it). Thanks for the assistance JoJo. Bob
 
Hmmmmmmmmm. In the previous post concerning fork oil capacities, I voiced the fact that I had been told 145 ml/cc's for my GS425L. I was told this by a parts man, (which always leaves me a little bit suspicious), and now I'm wondering if it was really 144MM????? Me thinks we need to research this a little bit more.
 
Just for the record 251cc =8.48732 ounces. so 8.5 is correct.

I must have missed that post.
Although I don't know the correct fork oil levels for a GS425L, I don't think that 145 cc's is enough. Must have been 145 mm's, measured from the top.
 
Yes, jojo, I'm beginning to think that this may be the truth. I observed that, even with leaky seals, the amount that I drained out was almost exactly what I put in. Also, the forks seemed somewhat "squishy" both before and after. I may just try the measuring trick at 145. I am a rather proficient automobile technician, but I am still a little bit puzzled by some of the instructions given here for fork oil level. Do you measure the depth with the bike on the center stand and front forks completely unloaded? That seems to me like the sensible approach, but I'm not sure at this point. Advice, anyone? P.S. - I don't have an owner's manual and am, obviously, somewhat of a novice where 2-wheelers are concerned.
 
As far as I know, the level is measured with the springs removed, and forks compressed.

A manual would tell you the right amounts. I only have one for my GS850.
 
The measurement is with the fork removed from the bike in a vertical position, springs removed and upper tube fully compressed.
