Good evening all,
I'm new to this forum and my first question is does the 280 W Nippon Denso stator fit as a direct stator replacement for the Kokusan? And is the stator the only thing i have to change?
I stumbled over my old GT 550 cafe racer in the garage very recently. It has been standing there since the early nineties untouched. I got inspired as i got my hands on some really powerful cylinders, heads, fuel injection rods etc. Over 100 hp already in stock form. And it looks like the package fits the old Suz block. (only minor machining needed) Will post some pics on the tuning side when i start having all hardware and can start the project. The old GT 550 is in for a huge conversion but I am in desperate need for more el power.
Any other good suggestions?

As you can see from the parts diagrams, the brush holders are different.
You will need to switch out both the stator & rotor for Nippon Denso parts.
Different voltage regulators are shown, but you can use either or an aftermarket unit.
GT380s & GT550s used the same alternators, so you can use an alternator that was from either bike.

Re: Upgrade for Kokusan on my Gt 550
Thomas,
That should be an interesting project. As far as I know the rotor, stator and voltage regulator all have to be swapped out. If you are making extensive changes to the bike, maybe it's appropriate to look at the alternator from a more modern bike. GSXR has lighter alternators that generate more power, but at high revs and they need a stronger (thicker) crank nose.
I would look at any modern bike that is not high revving. Say maybe a Ducati or other twin might be a suitable donor.
