Hi there,
This is my first post, although I have been lurking for some time.

I have had my FZR for a few years now and have kept promising myself a overhaul and upgrade session at some point. I have now started massing parts for the overhaul which I'm hoping to do at some point in the new year (after a 9,000km rally to Africa on a pizza delivery bike, but that's another story).

I use my bike as my daily rider out and about around Sheffield, and a bit of hooning around the peak district. The roads in Sheffield are terrible and I have just noticed I've bust a fork seal. I was thinking of putting in some progressive springs now, as I have to take the front apart, but can find little to no information about the size/rate of the 3EN1 springs. I did use the calculator on the Racetech site which gave me some numbers, but I was unsure, as it doesnt specify model numbers. Hagon do progressive springs for the RR, the SP and the 86>(3BF/3TB?) models. Would the latter springs be the ones to go for?

Needless to say I am a little confused...

Have you got a budget in mind ?
I think Hagon springs come in a bit under £100 and are usually sold with oil.
I'd look at the springs from a FZR600 3HE

But here's what I'd do ....
Have a look for some FZR600 forks from a later 3he and also get the brake discs (298mm). They should drop into your triple clamps, the front wheels should fit and your calipers will bolt up too and you'll have bigger discs.

Alternatively there's Kayla's front end from a YZF750 on the bay http://www.ebay.co.uk/itm/Yamaha-YZF750 ... 3a6ad4ee13 bung her an extra £30 and she'll put a different stem in for you so it will bolt straight into your bike ... That's upside down sussy's 320 brakes calipers the lot ... which is nice.

ive got a set of forks with new seals, oil and progressives in that i'm selling. will split for just springs if you are interested, pm me!

He might as well buy the forks to save the trouble of fixing his

just for another take on the spring thing,

i never rated the progressive springs that much as there just a generic spring (albeit progressive) for a particular bike and not rider orientated
i'd go (and did) with maxton replacement fork springs and spacers made to suit your weight and style and only about £20 more than hagon progressives, you gotta get your own oil though

or those rather sexy 750 forks of kayla's, all depends on your budget

I put 2litre ford granada (pinto) valve springs ontop of the standard ones and cut 15mm off the preload spacer tube. I did have loads of springs, but cant for the life of me find them anywere, but they make the forks feel great. Give them a good clean inside while you got them in bits aswell.
Cheap upgrade if you have any kicking about!
Cheers
Ian

Agree. Use the correct springs for your weight and rider style, rather than progressive springs. They were a big thing back in the day, but conventional wisdom now suggests correctly set up linear springs work better.
