After some research it looks like Ohlins doesn't carry a shock for the original modular bikes anymore.
WP Suspension looks like the hot setup for the rear. The front looks like it's going to get a race tech rebuild as well. All the old reviews remark about the way too soft suspension so perhaps my suspension is just about right on the mark for these bikes in stock config! I'm a 250 pound rider and it's way too soft even with full preload and both rebound and compression 2-3 clicks out in the front. The back is at full preload and still sags 2 inches with full rebound cranked in as well. The suspension is balanced this way and the bike handles OK but would be much more confident with stiffer components.
Found lot's of conflicting information about carbs and the airbox. Some say it's a resonator and removing it will cost lots of hp. Others say K&N pods are a hot setup for it but sacrifice some mid-range to gain top end ( a typical issue with pods).....pods look great and sound good so I may go that way even with no gain.
The ignitor on pre 96 models also seems to be possible to alter by cutting a wire making it a "750" ignitor that allows 2000 more RPM on top - no additional power but the bike will supposedly hold the peak power (roughly 100hp) across the extra 2K of RPM making it much friendlier on the track.
I'm also looking to find sprockets for a 520 X-Ring chain conversion. This should remove a few pounds from the chain as well as shortening the gearing.
The bike was super cheap $1800 and I hope to build a nice twisty road \ track bike. It's low cost lends it be "disposable" in case of an oops. The cartridge fork means it's relatively cheap to have it rebuilt with better internals. The rear may be expensive though.
Thanks for the responses and help. Any other thoughts are appreciated. I did check T595.net but very little information about the T3 models was available.
I'd like to find frame sliders for it if anyone can tell where they are available.
