Im not sure about the sag yet. Now Ive just read that the fork legs need to be extended when getting the specs for the preload spacer. Correct, "preload" is the amount the spring is compressed when the suspension is fully extended. Yamaha George directed me here when I started looking into my front...

I'm just saying that while I don't have the personal experience doing the tuning (thats left to the applications guys), I have seen the dyno curves of Race Techs emulators and Harley Davidsons emlators using both straight rate and progressive rate springs, and the damping remains reasonably consista...

To continue my last post, this is very possible. Do you have any evidence to support it though? I still had quite a bit of preload when I set my sag on my progressives. I know the previous owner raced the bike but are you going to be using it for race or street? If it's race only I'm with everyone ...

My guess is that someone added the emulators cause they found them cheap somewhere and added the pvc spacer to help with the bouncy stock springs. Stock, the preload spacers are longer than that-about 6 inches (and steel-at least mine were-part # 1WG-23118-00-00). My '96 had straight rate springs f...

Yup, pulled one out. Slayer, either your springs are shot or the lady did not know what she was doing as those emulators DO NOT work correctly with progressive wound springs. Whilst RaceTech are nice the price I found a bit excessive and found a local (3 miles or so away) spring maker at about half...

No the bike is not stumbling while under load nor while free revving. I understand that you don't need to use a choke. However if the bike idles perfect while cold once the motor warms up it would be feeding an excessive amount of fuel into the motor under closed throttle. If this means that the ext...

Well the subject about sums it up. My bike's run awesome for the couple months that I've owned it. No stumbling or bogging. However I've never needed choke when cold, just a quick throttle blip and it settles right down to 1100rpm. Does this mean the idle circuits running rich? Will it hurt my gas m...

Wow! Great link George. Awesome information (with the exception of cutting the springs, they're wound tight and ground flat for a reason). Well I installed the springs with a little too much preload but holy crap just the spring rate change was amazing. She still dives pretty badly under braking but...

Thanks for the help guys! I really do (at least I like to think I do) know what I'm adjusting in the front end, I guess it would give me a better starting point if I had a rough calculation for my desired preload in lbs. I don't really think it would be too hard with the exception of how far up on t...

I picked up a set from progressive suspension. They list a 3.75" spacer but that doesn't seem right. My springs come up to the bottom of the threads and when I'm trying to install the cap I can only compress like 2.6" by hand with the forks topped out. guess I need to start working out.

Hey guys I just opened up my forks to drop in a new set of springs to find that my spacers looked short compared to other pics I've seen (the bike is lowered so I expected this). Does anyone know how long the factory spacers are so i can cut fresh ones to return the bike to stock ride heights? The c...
