flywheel for Kokusan ignition system

[jpitz31]

Hello,

I made the change to the Kokusan ignition systemm I am looking for the newer two pickup flywheel. Does anyone know which flywheels are compatible with a 1990 750 sport. There is a 900 ss flywheel currently on ebay. Just wondering about compatibility?

Thanks

900ss flywheel will work.
You may have to swap the flywheel holder if it is an early Paso with a coarse spline flywheel hub.

of course it should be from a carbed 900SS not a SSie

Do you have a 6-spline or multi-spline crank on yours?
750 Paso cank-flywheel works w Kokusan.

I would download spare parts list f various models fr years like yours.
There are several parts that need to match,
f e w another flywheel, starter gear/sprag may be different.
Alternator is another issue.

I hope I don`t start any confusion, but my P750 is a 86 and an aftermarket flywheel intended for Supersport/Monster fitted perfectly. There was just one thing. There were some bolts that needed to be changed. I don`t really remember if they were the bolts from the flywheel or if there were some below the flywheel. I only remember my dealer telling me these needed to be changed with newer ones with a flatter had otherwise they would touch. So be careful and turn over the engine by hand before starting it.

OK, all should be fine w that flywheel then.
I just had some experience where f e different starter gears weren`t interchangeable
even between 900`s and 600 don`t fit 900 etc.

Hello All,

I have a related question on the kokusan flywheel. There are serveral flywheels post 1998 on ebay. But I cannot find any pre 1998 flywheels. I have the 4 pickup flywheel.

What would be the feasibility of milling off the two upper pick-up points and leaving the two lower pickup points on the flywheel (as show in the maintenance manual when the #1 cylinder is at tdc)

I can locate another 4 pick-up point flywheel from a paso.

I have been running the 4 pickup point flywheel with the kokusan ignition and I think this could be causing my high speed bog.

Thanks

Joe

note the flywheel is balanced so removing parts will unbalance it causing vibration and some damage sooner or later.

[Tamburinifan]

I have 2 pre -98 flywheels f Kokusan to sell. Where are you located?
Do you have 6 spline or multispline crank?

Milling would need rebalancing to work as Gerhard states.

Hello Tabmurinfan

I have the 6 spline crank.

You can PM me with the price and shipping. I have a bid on a flywheel that paso750 found on ebay. If it does not go through I will more than likely purchase one from you.

Thanks

Hello All,

I changed out the old flywheel with the new one I purchased on ebay and that fixed my high speed miss.

So the Kokusan ignition change out was successful.

After all of the troubleshooting I went through it was really nice to get the bike running properly.

So I decided to tear it completely down and clean it up.

I did read a bit of interesting article on guzzitech.com on proper testing of the dual pickups.

Here is the link:

I will be posting some pics of my progress.

Thanks
