Something light for the drags i guess, i didn't know you could change it

Not designed as a rebduildable unit. Of course anything can be reconditioned, just not worthwhile to do so when better aftermarket units are available.

People have been rebuilding, reshiming & changing the oil from day one on them for drag racing & run into the 7's. $10.00 for oil & 1hr of my time is alot better than $1000 for a "better" shock. Leigh

umm if it were that simple suspension gurus would be out of business.Yes alot of shocks are rebuildable but shim stacks and valve hole sizes,oil viscosities,bleed needles etc all affect each other.A thicker oil for example can lead to less control as less oil flows through the valving and more bypasses via the shim stack.Take it to someone and tell them what you want to acheive and it will still be cheaper than a new shock but the results for overall performance won,t be as good,Ive been there and done that with standard shocks before.Hats off for having a crack but theres a bit to learn to save a few hundred bucks.

Dont want to revalve this one, just strip, clean, inspect, reoil & regas. Leigh

I often use the racetec site for reference,, product search will list a recommended weight oil (and the complete racetec range thats applicable to your bike..) it will list as US1 etc but there is a x reference there somewhere to let you know what that is in real oil numbers
