Hello everyone! Does enybody have experience with TP pro series engines? I also wondering is my engine original on my 1999 Vintage Sport or it was replaced? Will appreciate for any technical description of TP pro series like HP, Torque, Compression rate etc. If you compare TP 107 with S&S 107 what is better?
I’d start with the engine serial number before assuming it’s original or a replacement. On a bike that old, there’s been plenty of time for an engine swap or rebuild, and the paperwork/build sheet would probably be the best confirmation.
As far as TP versus S&S, I’d be more interested in the condition and exact build of the motor than the name on the cases. A healthy, properly set up TP 107 can be a great engine, but the cam, heads, compression and tune will make a huge difference in how it actually performs.
If you can post the engine numbers and a few clear photos of the cases and heads, someone familiar with the TP Pro Series may be able to identify exactly what version you have.
