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

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...

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 think? :ninja:

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

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.

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.

LOL!!!!
I changed mine by 5mm and it made a significant (noticeable) difference in the handling and mid corner behavior.... what you did was just wrong... and like you are noticing, dangerous.

I almost don't believe this, because it is just so wrong.... did you also put a car tire on it for improved contact patch area down the main straight?

This threat is blowing my mind. The fact that you don't even remotely understand bike geometry tells me you certainly should not be racing, let alone track days. Go sit down with any of the local suspension gurus and get your shit straight before you hurt yourself or someone else. Or, better still sell your bike for the winter and learn a bit about bikes in general and buy a new one come summer.

No kidding
Yet another shining example of someone getting on here that has no clue what the fuck they are doing and refusing to listen to those that do.
Amazing
I hope you don't fuck yourself up too bad in the crash that is sure to follow

Dude. Just leave the bike stock, and do some track days. You may actually feel more comfortable riding the bike the way it was intended to be ridden. Those bikes were BUILT to be more comfy than a supersport.

If you really feel the need to spend more money on it, than look into getting the stock suspension worked for you by a shop. DO NOT screw with the bike if you are not sure what things will do.

Honestly, leave the damn thing stock, and you daily rider. do some track days, and see if it's something you REALLY want to do. if it is, start saving some money, and buy a cheap track bike.

I would hate to see you get hurt due to lack of experience man. Be careful please.

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
id like to race but i dont think i can afford it yet. im going to do more track days and try tog et a job at bowing to support the costs
I like all of these things that you call stuff.
You get a dot the color of the highlighted words. Also for paying attention, acknowledging and accepting advice and being willing to admit that you're best off getting a professional to sort it out and advise you.
You don't need to be able to build a bike to have fun at track days with it even if it does help.
You win the internet for the rest of the day.
Do with it whatever you wish.
