my bonnie project started when i joined the new triumph Bonneville forum, playing with jets and exhausts, that kind of stuff.
A guy called Jorgen Lindskog was the pioneer for hotting up bonnies and he did a fuel injection conversion then turboed his bike. I got on the band wagon and joined the megasquirt list which deals with diy efi.
I miniaturised the design (i was a printed circuit board designer) then converted my bike to efi using suzuki gsxr 750 throttle bodies and injectors with a gsxr 1000 fuel pump. The project worked and i was able to ride and tune my bike using a wide band lambda probe, a laptop on my back and rich lean buttons on the handlebars with the lambda display reading the exhaust. I dynoed it on a rolling road to set the last bit up at 72rwbhp. By then Jorgen was over the 100rwbhp mark taking it to 120 before building a purpose built drag bike.
In its
form now he is running 160rwbhp with a 1/8 mile of 6.1 or 9.5 1/4 mile all from a bonnie!
I rode my bile to sweden and let him do his magic, it was easier for him as i'd already done the efi and the software he used was compatible.
My bike runs at 0.6bar and has around 95-100rwbhp, a plug on the turbo can increase the boost to 0.8 bar but i'm still getting used to the power as it is. The front comes up in first easy! i came out of a roundabout the other day, gave her a big handful in 3rd and the front went very light! amazing the torque, from 3.5k (don't want to load the engine to much) open her up and she pulls like mad.
I had the carelo (sp?) conrods fitted, big bore kit 905cc and the rev limiter adjusted to 8.5k. while it was being done i had jmc make a new swinging arm as well,
next is a new paintjob

many thanks
