Title: Fork protrusion
Post by: Fraser on 19 May 2015, 12:30:22 pm
Sounds like a very rude word !!  does anyone know the standard amount of fork protrusion on a 98 ( the bit above the top yoke )   I've lost my bit of paper with dimensions LOL
 
thanks

That's why I viewed this thread! :lol

I've only ever seen them flush on a :faz but I'm thinking there's nothing wrong with them protruding above the yoke provided you do both sides exactly the same, as I've done on previous bikes I've had, this will change the steering charatistics and handling of the bike though.

Fraser, i was trying to find the same thing - 1998 Service Manual  - section 7-47 installing the front fork legs, they say

"Make sure that the inner fork tube is flush with the top of the handlebar holder"

Download it and check it applies to your model....it might differ but doubt it

Will get  a few pics of mine when i think they are where they should be.....input from some more experienced would be good on this one....for my ref anyway

Usually the main reason for the tube protruding above the yoke is to lower the seat height for short legged people.  Have to make sure mudguard doesn't hit the bottom yoke or radiator on full compression but i guess you'd have a couple inches protruding before that happened

I think mine are ok, the manual shows a protrusion like i have, they are not flush.....how are other peoples......flush or slightly proud....

Mine are the same like on anutz pics and this is the same like it is shown in the manuals for all model years.

Is it interpretation of the above in the manual that Anutz has quoted coz the bit protruding in the pics is actually the cap aint it...not the actual fork tube.

yep so my cap is protruding, and the inner fork tube in which the cap sits is what i have level or flush....with the top of the yoke.....thats how i read it any way...

any lower and it would be compressing the cap so i am not sure thats a good thing....any higher i have no idea, i assume many people vary their settings....but manual wise the pics show what i did

Id agree with you anyway Anutz....maybe when folk fiddle about they think it is intuitive to have the cap flush but like you say that's a bit of an uneven pressure on something probably not designed to be clamped around.
