I hear you - I'm spending some reasonable money on my 900 as I intend on keeping her for ever. I'll have to bite the bullet and pay for some dyno time on mine as with the 40mm carbs, ignitech ignition, mwr air filter, silmotor 45mm headers and 2/3 lengths cans its going to be all over the place
Like a fool I bought a ww2 jeep just as I was going to properly make a start on the Monster so I know the hazards of "toys"
