    So i dropped the triangke down the forks about 30mm so i could fit vortex clip ons on the bike right above the triangle tree, i put im emulators and the forks are a little stiffer but the bike has much less rake and trail now so when im going 60+ it feels terifyingly unstable compared to how it was stock. What can i do to make it more stable other than a home made mounted steering damper? Im scrared of highsiding and dieing like iv herd in so many storys:shock:

    not that I'm a suspension, racing, or ninja expert...

    but could your clip ons go just under the top triple like on a super sport instead of over?

    that would give you a a touch more "race-y" position, and stock suspension geometry

    Wut?

    30mm is a lot to raise the forks in the triple. Put the clip ons below the triple tree.

    i was thinking of that, my only concern is my front brake fluid box not having room being under the tripple tree. ill see if it fits though

    Those clip-ons are probably designed to go under--meaning you don't raise the forks at all.

    Vortex should have some type of instructions that describe this. Call them if they don't for some help.

    Mainly familiar with Woodcraft equipment and been extremely happy with the type of fit, quality, and instructions that come with kits such as these. If there are other adjustments to be made, the kit instructions have usually included notes about other adjustments.

    Sometimes clip-ons are only meant for race plastic, not stock bodywork.

    If you need some additional help--get a hold of Barry/April at KFG.

    Let us know how this turned out...

    Clip ons go UNDER the top tree, not over. That's your issue. cjohns hit it on the money.

    That depends on the bike. My 650 actually has clipons on top of the triple, but my forks are longer than his. I think you will have a hard time fitting clipons under the triple with stock bodywork. It will clear with catalyst race bodywork, most of the other race bodywork I know of requires you to cut for clearance.

    With a stock shock on the back and the original forks you will want about 10mm of tube above the top triple. 30mm is way too much.

    You can pick up different master cylinders with remote reservoirs and smaller reservoirs. All are fairly cheap.

    Can you run non stock master in SS?

    Edit: I assume you want to race not just do track days.

    iv read somewhere that you can drop it up to 25mm safely and i just measured and adjusted it, it was at 40mm actually. i dropped it to 30mm and now the top 1/4 of the clip ons aren't touching fork. it feels ALOT more stable. I'm starting to consider a steering damper, i herd if i weld a bracket on the frame i can mount something.

    If you drop the front, it is always wise to drop the rear the same amount and have a shock modified to limit the travel as to keep the same geometry.

    A job at bowing? There's a butler program at Everett CC I think.

    My bud used drag bars at first. Then Barry at KFG did a 636 fork conversion and put on a Penske. Viola, badass little bike. I'd suggest trying those first.

    636 fork would put it firmly in superbike territory, probably not a good move if he plans to ever race SS.

    I'm not an SV setup expert, on R6 rear was up a few mm and front was lowered, running 211gpa. A few mm here and there was all it took, when you're talking 25mm-40mm it sounds pretty excessive.

    25mm is still a LOT. I have 25mm of fork tube above my triples on my 650, but I also have 636 forks that are 10mm longer than the 650 ones. My shock is about 4 mm longer than the stock 650 shock as well, though. You should not use a steering damper to mask a geometry problem.

    Keep in mind though a bike like an R6 is a lot closer out of the box than something like an EX650, EX250, or SV250.
