Hi Crit (@Crit),
Thanks for being a customer and nice comments.
Early Sr3 were mostly carbs, as we bought base production line motors only directly from Suzuki Japan, we could not buy with Suzuki injection systems, that was handled by another dept.
The keihin flat slides gave a very easy tunable performance increase, and simple to install “off the shelf “.
Jenvey really did not do an injector body to suit and we worked with them together to refine and produce an affordable solution along with MBE .
The motor management systems took a big step forward when we fitted first life racing system ECU’s around 2006/7 after we had worked together with Life racing on the LMP2 SR9 project – I am still using them today, Mike Lancaster and Mark Colby are two of the brightest people I know on engine management.
Hope this helps.
