R1 1999 offset

Ok, i have a R1 1999 and i have mounted a front fork (legs), brakes and wheel from R1 2005.

But like i know the legs are 15mm shorter than the old.

How can i extende the new forks to the missing 15 mm?
Or is there a easier way?

I have read a lot about the "head shake" problem.
I can't try my bike yet becuse of snow so i have to trust everybody ho have done this swap.

But i can't find enything how they have fixed the problem.

I've done the same change to my '99 with 04-06 R1 forks. You can set the top of the fork outer tube flush with the top of the upper triple, and the fork cap will be the only thing above the triple. Here is a pic of mine, my tubes were raise in this pic.

I see that you use another triple tree.
Is it same offset like triple tree from 1998-01, 2002-03 or 2004-06?

Have you changed the triple clamp, or just the forks?

I have the 98-01 is 35mm offset, 02-03 is 25mm and 04-06 is 30. Then it varies again on the newer bikes. There is no perfect offset, everyone has their own preferences, stability vs turn-in, etc.

Sorry, I meant the OP. But I think he's answered the question now.

I have the standard forks and triple tree. My plan is to have the forks revalved because I want to keep the bike looking original.

Most people replace the triple tree because the 98-01 bikes have quite aggressive steering geometry. Either 02-03 or replace the complete front end from a 04-06 - everything including wheels.
