Possible upgrades?

BigNinjaDave · Post by **BigNinjaDave** » Mon Dec 18, 2006 12:40 pm

As I mentioned in the newbie section I recently bought a zxr400 h1 track bike but she has a few issues that I need to resolve. The suspension fore and aft is a soft as one of my granâ€™s sponge puddings. The brakes are in a bad way and the oil radiator & hoses are shot.

Now before I set about stripping everything down and replacing bits Iâ€™m wondering what if any improvements can be made? Parts used from other models?

As this will be my first attempt at striping and rebuilding forks / rear shock where is the best place to get the seals, springs, etc or does anyone do a kit with everything I am likely to need?

Cheers

Dave

there's usually cheap fork seals on ebay. springs I have no idea, mine seem stiff enough

I think the calipers are common among quite a few bikes of that age. People have also done upgrades with other types - gixxer ones seem common. If you do a search you'll prob find loads of threads on the subject.

don't forget to check out the fork rebuild posted in the workshop section.

For handling, i think most of the racers send thier forks off to someone to setup, i think its sloweracing who send them to a guy in Holland or Belgium! You can get an Ohlins rear shock for the ZXR, seen a few pop up on ebay a couple of times, not cheap tho!

For brakes, you can fit 6 pot calipers from a gixxer K4 (i think) with minimal modification. But dont know about better performance on that front.

ZX6R front end goes right in using the same yokes,

As for interchangeable parts, i know you can use ZX6R clip ons if you fancy fitting bar ends, not sre what else goes other than that. Most L and H parts also swap, but be careful cos not all!

I've started a thread for interchangeable parts

Right the track bike is starting to come together now!

I've managed to source a WP rear shock and some Maxton forks as well as picking up a sprint damper and refurbished front brake system.

The only problem I'm left with is the oil cooler and hoses which are shot. Anybody no of a decent after market one I can use without having to fashion new brackets etc?

I've seen a H1 for sale at a reasonable price so might buy that, take what I need and break the rest on ebay.

Not sure what model the shock is but it came off an L1 race bike. It was being offered at a silly low price so if it don't fit I'll make it
