I ran a 16/32 on my 750 twin for a lot of years. You have to get a custom from a place like sprocket specialties (?) and it's pricey.

Knowing what I know now, I would recommend going with a ratio of about 17 front and 35 to 36 rear. Using a 32 rear makes the chain rivets hit the rear wheel hub and the chain bangs on the swing arm.

Your problem sounds just like a bad connection between the Stator and the R/R or R/R to battery.
On the 550 I had in the past, the 4 way connection on the right side of the bike behind the side cover, down near the swing arm pivot, was cooked. Replaced this and cut the wire back about 2" on each side to get to good wire that had not been heated. Cured the charging issue with out any other new parts. Got more voltage to the ignition also, which cleaned up the plugs and the bike ran much better.
Good Luck.

Sorry to hijack but does anyone know what hub I would use on a gsxr 600 swingarm I found a company that sells a complete front rim but not one for the rear and I'm not sure what rear hub I need.
PLEASE HELP!!
sorry again for butting in

im planning on running all the gsxr components as far as calipers and rotors

also wondering how mounting the swingarm came out i had some ideas on how to run the kz pivot bolt by creating a slug and some spacers but i was a little iffy on that, not knowing the strength of the stock pivot bolt and if it would hold up
any more info on that would help
thanks again

I have the swing arm mounted on a parts bike at the moment, it was easy to do! The stock pivot bolt is plenty strong enough, most of the force I believe is on the shock not the pivot. Your plan with the spacers and slug sounds like exactly what I did.

the bushing i need is like the one on the left(google pic)..from what i believe its called a pilot bushing..its for my swing arm..i need the ID to be for the original Kz mounting bolt and OD for the swing arm
ID-1615
OD-27.95
Length-36.04

The larger OD of the female fork tubes provides more area for the triple clamps to clamp to, The end result is a fork assembly that deflects less then a conventional fork. Most inverted, or male slider, forks are built around a cartridge damper which is superior in almost every way compared to a damper rod fork.
If you have the time and money ( lots of money) male slider forks are a great modification for any mid 75s and newer motorcycle. Lots of money!

Without a doubt, but at what point does the wonderfulness of the newer forks get overwhelmed by the weakness of the antique frame?

Only your wallet knows the answer to that question. I have found that it's the forks and swing arm that cause most of the flex in 70's eara motorcycles. Stiffen those two systems, align the wheels, invest in proper rate springs and modern damping and most (not all) mid 70's and newer bikes handle very well. Especially when they are kept on street tires.

sorry if i posted under the wrong category..
so i got my swing arm from a vfr, single side swing arm. got it to fin in the frame, still using the original swing arm bolt.so i need some bushings to fit the bolt to the swing arm..if anyone can make them at a reasonable price or knows someone that can please let me know. thanks

Lack of cash has kept me from doing much on the bike this Summer, but I've still been looking for inspiration on how I want to really build it back up. I like the street look, but it's just too 'common'. I ran across this picture today and it has me thinking, but there are some questions...

I have a 16" rear wheel, but I see an 18" was available, and I kinda like the look of the same-sized wheels better. Does anyone know if this wheel would be a straight bolt-on, or if I would need to replace the swingarm or brakes or anything else? (Also now I'm curious if this bike actually has the larger rear, or if it's just an illusion of the photo)

I like the look of the duck tail without the fender, but the one from the 70's KZ1000's feels a bit long to me. The tail from the KZ650 has a nice lip at the back and appears shorter. Is it actually shorter? (And yes, I know that frame is different and I will have to make mods to add a tail on mine.)

That seat... I've never seen anything like it. It gives the look of a "badass biker" but it's a double seat. I'm not so sure how that thin of padding would feel on the rear after a couple hours of riding, but it has me considering what it would take to make my own seat pan... Anyone have tips or links on making a custom pan? Anyone seen similar seats for sale that I might buy?

I had to get confirmation that MotoGP Werks was remanufacturing Cal-Fab swingarms as seen in this article: www.motorcycle.com/top10/top-10-things-motogp-werks.html/8

Red got back to me, and yes indeed, he purchased the company and Cal-Fab swingarms are being manufactured once again!!!

The article is true, the price will be $599. A 150-series rear tire will fit easily.

Right now, they're only manufacturing a disc brake version for Z1s, unless they get 5 to 8 pre orders for the drum version. I'm interested in a drum brake version as I like the lines of the drum on the back of an old KZ, and I do not plan on ever doing a track day on the old bike.

I wanted to put out a feeler to see if anyone else was interested in a drum brake version as well. Let me know if you are!

Thanks!

Oops, sorry guys I thought you already new this. He started with the Gixxers and is now making one for the KZs.

Haha yeah, this is news to me! I've been concentrating on my ZRX lately, but as I finish the mods I intend to do to that, I'll start focusing on my KZ again. Miss my old gal!!!
