my bonnie project started when i joined the new triumph Bonneville
forum, playing with jets and exhausts, that kind of stuff.
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.
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.
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
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
