I have a couple questions,I know with stock springs you want the oil 7.5" from the top of the fork.... fork fully compressed right? Also,when you guys specify a volume of oil, is that per fork,or total?? Reason I'm asking is i followed the instructions on Rex Hefferan's webpage (thanks Rex!) and he says close to 420ml if drained the way he specified. Incidentally I used Bel Ray 20w fork oil (I'm 6'4" 300lbs) And might try longer spacers until I get some new progressive springs. Service manual is first in line though! TIA! Steve

Hi Irrespective of volume fork oil height is quoted at 190 mm +/- 2 mm the quoted volume is 420 mL +/- 4 Volume is per leg. Height is measured with the leg fully compressesd....YES. It does not matter if the tubes are in the clamps or not as long as you take the level in the center of the rule, better if you are using one of the graduated fork oil tools, but a steel rule works just as well if you put it down the tube to say 300 mm and then deduct the reading, you don't need to add much oil to change 1mm maybe less than a tablespoons worth. Sorry but my spring rate chart goes off the top for 300 lbs but it would be up in the .5kg/mm range or more. Try calling someone like race tech on 909 594 7755 Oil viscosity only sets rebound damping. You could try pre loading the springs up to 20mms, but I would try and get the right rate for your weight and then they do not need to be progressive, which is a compromise Brian A14 TE 410E Honolulu, HI [Non-text portions of this message have been removed]

Hi Russ. Many years ago as I was waiting in line at the tech inspection at Bonneville, I noticed that the tank of my CR110 Honda was dripping fuel. Terrified that the inspectors would also see it, I was at a loss of what to do rather than push out of line, remove the tank, drain it, and try to weld it closed, and waste a whole day of qualifying. At that point, a nice little old man noticed my problem and walked over to his motor home and returned with a bar of hand soap. He discretely rubbed it on the offending pin hole leak and it stopped leaking. With occasional re applications during the rest of the week, it stayed dry. I have carried a small bar of soap in my tool box for the last 25yrs just for that emergency. If your fuel tank is under warranty, and at 600 mi. I guess it is, this might be a cheap fix that will save you a few bucks. Good luck, Terry
