Can anyone tell me how much oil should be in each fork leg on a 2TK and what grade is reccomended.

To stiffen up the front end a little, change the oil and replace with 15wt to a level of 100mm (no springs in when measuring). If still not stiff enough, reduce to 90mm.

Standard oil is 10w.

Cheers, put 15wt oil in to 100mm, seemed to stiffen things up a bit.
Unfortunately one of the fork tops was completely seized up and it got very chewed up by the time I'd got it out. £50 for a new one and a month to wait for delivery. Ouch!!
