fork springs

[DeanR]

Anyone know if Heavy Duty fork springs (2H7-23141-10-00) for a standard will fit a special?

no

Hey Dean,

Well, here's a list of part #'s for the years and models, and you can see that they are different between the Standards and Specials throughout the years.

81H: 3H5-23141-00-00 SPRING, FRONT FORK

80G: 3H5-23141-00-00 SPRING, FRONT FORK

81SH: 3J6-23141-00-00 SPRING, FRONT FORK

80LG: 3J6-23141-00-00 SPRING, FRONT FORK

79SF: 3H3-23141-00-00 SPRING, FRONT FORK

79F: 2H7-23141-00-00 SPRING, FRONT FORK

78E: 2H7-23141-00-00 SPRING, FRONT FORK

The Specials are longer upper tubes, and so require a longer spring. However, I extended my Special's upper tubes 4" and all I had to do was add a 4" PVC spacer tube!

So....With the shorter Standard springs, I would think that it would be just a matter of adding a spacer to take up the difference in length for your special, just compare your OEM's to the NOS heavy duty ones!

However, if the NOS ones are gonna run close to $50.00, then just buy some Progressives instead!

They caught my eye on ebay and are at $6.50! at least at the moment.
Hey TC, the core number is the same thru your list so what does the '3H5' etc. indicate?

[John]

The 3H5 prefix tells you what model and year the part was first introduced. Let's use the TCI module for an example...the first three digits of the P/N are 2H7. Using the serial number chart you'll see that the part was introduced on the 78 xs11, and was used until 1981. That's why the number never changed. In 81 Yamaha changed the module, hence the 4R0 P/N. The core number will remain the same no matter what year/model the part was originally issued. Many parts are off the shelf and were used on different size bikes. tail lights, turn signals, brake components, etc. Use Yamaha's online parts catalog to find a P/N,or to check if a part from one model is the same as another model.

Dean;
The other thing to check is are the springs new old stock? If they are used, don't bother!! Age and the weight of an xs1100 sitting on the springs WILL make them almost as bad as what you have. Progressive springs fit, and are new, so they will work well for the next ten years or so.
Just my $0.02

I passed on the springs. They were new and went for $20 but these seem to pop up on ebay quite often. Mine are original but seem to work fine however if I put new ones in, sounds like I would probably notice a difference.
