KXDINO:
did you ever do the frame angle mod or less off set triple clamps to fix the handling on the 07 ? i did heaps of development on my 06 , i treated it like my own personal works bike , it now a keeper. dont ride it much any more as i have 11 bikes , as i getting older i tend to ride the easier to ride kxf 250 and 450 bikes , and the kdx 200 for forest work were u need rego.

What offset triple clamps help the 06s?  I know you said relaxing the head angle to 26.5 helps, but could you fix it with triples and not have to weld the frame?

I havent done it yet. Every time I think Im ready to do it something else pops up and takes cash away from the project. Hopefully sometime this year. I also have a couple other bikes to ride so it sits alot.

KXDINO:
i never tried a different offset on 05 on wards but i read somewhere they did and they used rg 3 which not 100 percent sure were 21.5 mm, i think std 25mm . i also see pro-circuit are doing a run of new clamps for these bikes but they dont give out what off set they are ,if you ring them they should tell you , i personally would just do the frame mod as 26 degree head angle is to steep , as most bikes are in the range of 26.5 to 27.5 and handle good , kawi went from 27 on the 04 to 26 on 05 onwards and didnt change the off set at all as well it sits up in the rear as well , i like the 26.5 frame mod with the 3mm longer link gold valve front and back and change the small base valve spring from std 2.58 to a 2.2 spring this is a good improvement for plushness just in it self while u got the base valve apart replace the plastic free pistons with rt alloy ones as i replaced many a set of kyb plastic ones on yz and kx that have smashed them self to pieces , these forks work a lot better after this, about the engine i tell u personally another day there a bit in that.
