Thanks Mantis
LOL
You know , you could easilly do it in an afternoon. Had to wait on some other unrelated parts and tires. Oh when you add in work, homework and the most important thing, HUNNY DO LIST it took a little longer.
Oh the HUNNY DO LIST

I had my 03 GSXR 750 front on a G2 frame. What must be done to put it on a G1 frame? The top bearing race has a smaller diam... I'm concerned with the drop in trail by going to a GSXR fork compared to stock because the offset is smaller and the fork length is reduced. The stock trail on the SV is around 98 mm; I suspect that simply bolting on the GSXR unit is going to result in a very squirly front end.
One solution is to run 70 series tires (we run these race tires anyway on the stock sv and actually drop the triples 7.5-10 mm which more or less brings you back to stock) and get GSXR fork extensions. This makes up for the shorter forks but still doesn't address the low trail....

Steve this is exactly why i posted in the 2000 SV tech section.
Im running 88MM of trail and was looking for advice on opening it up some. I didnt know that exstenders even exsisted. I am currently flush with the tripple and dropping is not an option. Take a look and tell me what you think?????
I am running 70's and the measurments are taken with that tire.
Def looking into the exstenders...

The bike must be very twichy @ speed. The fork extenders are from Race Tech or Traxxion but not cheap @ around $100 each. Another solution is to increase offset between the forks and the steering stem - requires good machine shop. Not sure that the GSXR front end is worth all the trouble. I'm actually running G2 forks with ZX6 cartridges. Add a Brembo master and EBC wave rotors/Extreme pro pads and you'll have a better front end without the higher weight of the GSXR unit.

Finally you can send the cartridges to Zoran from Twinworks who can do internal lengthening - unfortunately only 5 mm in the newer forks (before, 10 mm were possible). Gettin the cartridges adjusted by Zoran is a good thing anyway, the way i hear it.

Its not necesarry. The 1st gen chassis works very well with the GSXR front end with no problems. The GSXR front end is .75 lbs lighter. (this is the average from 7 GSXR front ends weighed against 2 SV front ends.) No matter what you do to the brakes on the SV they will not be as good as the GSXR. That being said, lots of guys dont need or cant use the extra brakes. Fast lap times can be had with either front end, though the stock front end runs out of talent until you drop a set of AK 20s in. And in the end I firmly believe the GSXR front end is capable of more.

Put it on the track this weekend and it felt great. The bike was responsive with quick and smooth turn in and no front vibs or twitchiness on the straights. I still have a lot of fine tuning to do but I am very happy with the up grade.
Had I not had the combo of new front, new track and rain I could have been able to be a bit more aggressive with it but I got a month to go thru my notes and impressions and apply them to the bike so that the next day at the track will be very productive.
