Suzuki GSX 1100 EFE Streetspecial

Hi, here are some more pictures of my EFE for your very nice website.
The engine has seen a lot of action on the dragstrip in the last 12(!) years.
In it's current state it has got what qualifies as a de-tuned Pro-Stock engine, measuring 1428cc's.
For street (ab)use I've built an off-set starter engine and recently a Ducati generator (and I thought Italian electrics were crap? - Mr.7/11)
At the time I was the first one using an extended swingarm and a homemade powershift system.
On a streetfightereshow in Leiden (Holland) we measured 172hp at the rear wheel. Later, with some heat into the engine it gave 176hp but after that we had to stop because the generator-cover started leaking oil.
First we thought the rotor had run loose, but later it appeared that the leftmost cranktap had started to crack and gradually detatch itself from the crank.
I've rebuilt the engine with a properly aligned, welded and balanced (which are all entirely different procedures!) crankshaft with a featherlight Ducati generator-rotor.
It now has so much torque and power that lately I prefer my '90 GSX-R1100 to prevent a nervous breakdown ;-)
It allready used to produce more power than a Hayabusa with a free-flowing exhaust system (I recently saw a Hayabusa with an Akrapovic system produce near 170hp at the back rubber - Mr.7/11) at any given RPM.
Best E.T. so far has been a 9.941 / 229km/h but I am convinced that it will break into the 9.8s.
I will make a serious attempt at that at Drachten this year but finding grip is the biggest problem at the moment.

Warming up the rear tire... yep, grip is hard to find


In his private workshop... needed for loads of rebuilds ;-)


Private dragstrip in the garden (1/100mile)


On the dyno at the Streetfightershow in Leiden... 176hp and strongest atmospherically fed bike (LOUDEST TOO!)
