Heavy duty front springs

[gareth]

Looking for a pair of heavy duty straight wound springs. These were an option back in the day for full dressed bikes. Despite knowing the risks, I purchased what appeared to be NOS on eBay. They were tightly wrapped in the box and I guessed that they were as listed. But, as you can see if you do an eBay search, most of these are the OEM progressive springs that have been removed and placed in the HD wrappers.

If you look at the photo, ( which I pulled from an xs11 thread that warned me about this problem...) the straight rate hd springs differ from the progressive style. The progressives have a section of tighter coils at one end.
The HD springs, the ones I need, have a consistent coil pattern from end to end.
I just purchased Racetech emulators for my 79F and a straight rate spring is recommended.
Let me know if you have a set for sale.


Thanks.

No help here, but using Racetech emulators and HD straight wound springs IS the better option from those here that have used that set-up.

Traxxion Dynamics in Woodstock, GA will hook you up. Mine were custom wound for $125. http://traxxion.com Call them.

Was hopin' you'd jump in there with some help Marty.

Thanks for the heads up. I saw these on the Bay this evening, listed as being from a 1980 xs. Squinting carefully at them, it appears they are straight rate springs, but I could be wrong.
If it turns out that they are out-of-spec or unusable for whatever reason, I will just return them and call Traxxion to get sorted.
Racetech also sells their own springs with a couple of options for spring rate.
For the moment though, I would just like to get some sense of the effect of the emulator installation at minimum cost. I was able to get the s3301 emulators at a discount so it started me down the road.
The bike needs fork seals anyway, so I might as well while I'm in there.

Regards.

Thanks, Phil..
If that's $85 per pair, plus choice of spring rate, and the quality is there, then that's really a bargain, spring-wise....

Yep, I run the .90kg ones with my FJ fork conversion on my 79F with emulators, huge improvement in handling and anti dive. Their customer service is excellent as at first I ordered the 1.0 kg rate and rode with them for a week or two and realizing they were too stiff. They exchanged them for a lighter rate quickly with no charge or hastle.

All the bits arrived this morning.
Should be interesting to see how the whole system works together.

I don't know for sure what your instructions say, but make sure there are at least six holes in the damper rods, IIRC.
