G15 Fork Length
Hi
I'm after a sanity check if anyone can help me please.
Having stripped, inspected and re-assembled a set of roadholder forks for my G15CSR things don't feel correct when I fit them. In order to attach the damper rods to the top nuts I have to compress the forks by about half their travel which then really restricts the fit and function of the gaiters.
Before I strip the forks down to measure individual components could anyone measure the distance from the top of the upper crown to the wheel spindle centre when the fork is fully extended please? I have 29"
Regards Mick
Edited to say: The forks will be stripped again tomorrow, I suspect I have the wrong dampers, 7 5/8" as opposed to 10 3/4", fitting the correct ones would result in a fork length of about 32" - does that come close?

Re: G15 Fork Length
Cannot help with the measurement I am afraid as the G15 is firmly strapped down on the bike lift awaiting replacement of the magneto.

Hi
A bit further with this one now. I was using the AN website as a reference Peter but couldn't find all the info I needed, on your advice I spoke to one of their Technical help guys, (brilliant service), and determined that I have early Commando damper tubes - too short.
New items on order - should increase the length of the forks by around 2"
Another step forwards - I hope

Sorry the pic is so darn BIG - but you can see at least that the fork length looked about right after surgery. Before, the gaiters were well-squished.

Hi Bill - Funny old world - I've drawn up a set of modified damper rods just in case the longer damper tubes don't fully resolve the issue. Should keep the springs and dampers functioning the same whilst extending the forks a tad

That was my thinking Mick. . . . . Great minds thinking alike - or Fools seldom differing??!! (Oh, and it's a no-cost get round, which is obviously the best sort when far too much has already been 'invested', ha!)
