hack of the dj-drive mod: apply it on VX 800 with swing arm rework

hello dear all,

i am planning a hack of the dj-drive mod: apply it on VX 800: i allready have bought

- vs 1400 final  drive hub
- vs 1400 swing arm and some little parts

question do i need to use the vs 1400 Swing arm !? or can i use the swing arm of the VX 800

Love to hear from you
btw: i want to rework the swing arm to  fit a bigger tire - to lower the rpms

background:

I commute 50 miles a day and love using the bike for the fun factor and fuel mileage.
Most of my commute is between 60-75MPH, which is in the 3700-4700 RPM range.
I have been considering different methods to lower cruising RPM's, specifically a taller rear tire/rim
or different rear drive gears. My specific requirements are a happy medium at highway speeds.
Here are my opinions on what I may need to do this:

1)optimum efficiency is typically at max torque RPM, which in this case is 3500 RPM according to Suzuki.
2)I would like to run 65MPH (average of different cruising speeds/most highway speed limits) at 3500 RPM.

In order to accomplish this, I would need:

A)a bigger tire - eg. a 30" tire, compared to 26" stock tire. This is a 4" difference, which is unlikely to fit under the stock rear fender.

B)Final drive reduction of 3.00, rather than the stock 3.503.
Now my question's to all of you is this: Are you familiar with any company that manufactures different rear differential gears?
Also, is there a different Suzuki (or other brand) gear that may fit the c50's rear diff housing that is closer to a 3:1 ratio.
If there is not a gear already manufactured, I may be in contact with a local high-performance manufacturing facility to see
if they can manufacture a 3:1 rear drive gear.

so is there anybody familiar with reworking the swing arm!? I want to do this!

no idea sorry, Sounds like a massive job to me, You're probably better off looking into buying a different bike.

I'd tend to agree with Simbo to be honest mate.
My VL800 has a VS1400 drive fitted and the bike now spins around 3250 rpm at 65mph in 5th gear.
Prior to the 1400 drive being fitted, it turned approx 3750 rpm at the same speed. If you're looking for 3500 rpm at that speed, assuming that your gearbox has the same ratios as the VL800, is it worth all the effort & expense just to drop 250rpm ?

hello dear all - very interesting thread - i like it.

can anybody give me the detailed data of the vl 800 gearing.

How are the steps - is there a full overview on the data!?

love to hear from you
