replacing springs with racetech

[erok011]

I put in my weight and it told me to use:
FRSP S3534095 RT FRK SPR 34.7x340mm .95kg $109.99

That is the cost for both I assume. Anyone know of a better deal (cough..cough.. Tmod) What else should I replace wjhile in there, fork oil and dust seals? anyhting else?

Terry is the man to talk to. It depends on what you are looking to get out of the machine.

Most people will drop in a set of cartridge emulators as well.

As Steve pointed out, the mods done to the suspension really depend on what you want to get out of them. I see you already went to RT's site and got the correct spring rate for your weight.

Yes the springs come in a pair, so you buy one set and they cover both forks. So tell me what you are looking to do and I may be able to offer some direction you would need to go to get what you are looking for.

well, I ride on the street, no track. I occaisonaly ride 2 up. I am taking the forks off anyway, so I figured that should be the first suspension mod. I can only afford to do about that much money, cant afford to do emulators too (and dont want to braze anything either). I am 200 lbs, so I would like a little more firm front end mostly. I do like to ride the onramps and occaisonal turn hard where possible (its FL they are few and faw between)

If it makes you feel any better, I had to buy 2 plain old torsion springs for my snowmobile for $172, and they were just coiled steel....................

ok, i just ordered the springs. Is there anyway to change fork oil without a special tool to measure the oil?

Make a tool using vice grips, some hard brake/fuel line, a piece of rubber hose, and a big syringe.

Clamp the vice grips on the hard line at the right height so that the tip of the hard line would be at the correct fluid level with the vice grips sitting across the top of the fork. Use the rubber line to connect the hard line to the syringe. Now you just overfill the fork slightly, and suck the excess out with the syringe.

Did you use the discount for Katriders.com in the deal section here?

Use a piece of welding rod or some straight thick wire and put a mark on it, Then use that for the height.

I'm not trying to steal this thread, but Racetech only offers front suspension parts for post Kats. Is it worth fixing the forks and not the rear suspension? Is the bike's handling noticeably better with just adjusting the forks?

Springs are available from Racetech for pre kats as well. It's the same spring for all the 600s, and you choose the year range for the 750.

It's worth fixing the front, but if the rear has not been touched/adjusted at all... the front will definately show up the rear (make it more obvious you need to upgrade it). It's not going to really perform any worse, you just have a better performance from the front and it's obvious.

See Tmod's thread below. He's been in cahoots with Racetech regarding the rear shock.

Racetech does offer the G3S shock and they do rebuild the stock 750 post shocks, Could the post 600 be rebuilt? I am sure it could but it is a emulsion shock and you would not get the performance improvement or adjustments that you can get from the post 750 shock. You can also can get any spring you need for all year kats, You just need to know what you need.

If you look at Racetechs site be warned that the spring rate for the rear shocks is incorrect and I have been reminding them that it is incorrect and they need to fix it. Any questions on spring rate for the rear just post up here and I can give you a idea on what will work.

Tmod, hope you see this, lol. When I put these springs in I weighed 205lbs, and i got the 200 lbs spring set. Well, now I'm 175lbs, will it matter much? Will it just make the front end a little stiffer? Should I go on HGH and try to put 25lbs back on?

[Tmod]

Just take a bit of preload out and you will be fine, It will be a little on the stiff side but nothing that will kill you.
