Race Tech springs

So one of my fork seals blew on my beloved 03 919. I've decide to replace the seals, oil, and springs.

I can get Race Tech springs through a friend that works at the local dealer but would like advice on proper spring rate.

I weigh 215-220 without gear and ride moderately with the occasional aggressive day.

The RT calculator gives a range of choices and I read on the forums the online calculators are usually wrong. I'm guessing I need a .95.

Would that be correct or should I go down to .90?

Thanks.

IMHO, I would go with the .90, I'm around the same weight and I installed .925's and wish I would have gone a little lighter.

Ok. That sounds reasonable. Thanks.

BTW- I'm running a stock rear shock if that makes any difference.

Do yourself a favor and upgrade the shock first.

He has to go into the forks to fix the seal. Great time to chuck those stock springs.

I weigh around 185lb in street clothes, and went with .95 Racetech springs.

You'd be welcome to ride it, but you're a whole Pacific Ocean away.

How do you like that spring rate? How aggressively do you ride?

I like the spring rate just fine. I have an aftermarketshock in the back [YSS] with a pretty firm spring there too, so overall some might find my bike quite stiff-legged.

I did the fork-stanchion zip-tie test after installing the springs to check on the amount of travel I was using, and it seemed ok - same at the rear, where I get surprisingly close to bottoming out, although the spring rates around 1200 lbs, I think.

The aftermarket shock is slightly longer than the standard one, so the rear end runs a bit high, and I pre-load the front to make sure it's not too nose-down.

It's the only bike I ride, so it feels fine to me, but someone who rides lots of different bikes back-to-back might find it steers weird, or rides too hard, or whatever. I like the firmness of it, but that's just me...
