<< Where do I get stiffer springs, and how is the stiffness rated????
I'm planning to shim them tonight to see if I can get rid of the
backfire at least.
David,
I am using 2 sets of springs in my carbs.One is a stock set the other is from
a dynojet stage one kit.I spoke to Mark Moisan at Pro-Star Columbus last
weekend and he claims he gets all his needles springs and jets from Dynojet.
Originally I had a Dynojet kit in my bike that required having the extra hole
drilled in the slide we plugged that hole off when we were dynotuning mine.
Feedback? I'm thinking I need a different taper needle to fix the
lean spot, but how are the tapers measured? I made a see through cover
on my airbox, so I know approximately where the slides are at this rpm
under no load. >>
You did exactly what my tuner and I were considering (the see thru cover on
the airbox).As far as needles I cant help you there as I am still using the
ones that came in my Dynojet kit when I did the pipe and jet kit.When you
find out something that works please let me know.
At least you have the benefit of the 02 Sensor I did all my tuning without
one.I think there is still HP to be gained on my bike with more tuning.But
after dynorun #110 then bike was running decent and I wanted to ride.
Good luck and if I can be of any help let me know.
