My buddy has a mid 90s Kinetic TFR that he wants me to "beef up" a little. I figured that slapping an old Polini country exhaust I have on there and drilling some holes in the air box should be a step in the right direction. Does any one know what number the factory jet in a 90s kinetic is? I'm thinking that with the new pipe and more air I should bump up the jet about 4 sizes. Does that sound about right or am I way off?
Never mind. I did a search (I should have done that first) and according to an old post it is a 45. I'll get a 50 and see how that works.
you are right about the jet, you can open up the holes in the restrictor dish in the air box, but you might want to get a handfull of jets up into the mid-50s range. Other thing is the polini long country will give it a bit of power and a few mph at the top end, but it kills the low end so it kind of sucks with the one speed, works ok with a variator so I would suggest that (variator and rear transmission from variated vespa), or a tecno estoril which is a good low-end pipe.
I already have the Polini pipe and I'm not planning on cutting and welding a pipe to fit with the pedals. (nice work on yours by the way) I'm just helping out my bro and he's a career college student with no money so we're going to do this with $10 worth of jets and some elbow grease. The polini pipe has to be better than stock. I think I am going to buy a few jets. Thanks for the input!
