question about timing advance

[Truck Tech]

I know what the timing advance does, but how much differance does it make say with a five degree advance.

It is supposed to give you a "sharper" throttle response. However, since many motorcycle engines are already running at the edge of efficiency at high rpm's, you will probably be over advanced and actually lose top end power. The Kat's run happily on regular grade gas so you could get some power back by running premium fuel but since it burns slower you also lose some of the responsive feel you gained (not to mention lightening your wallet).

You will notice quicker throttle response, faster warmups and better mid-range pull. Top end I don't think you will notice anything one way or the other.

i agree with everything except the quicker warmup, i think it made mine worse untill i jetted it out. Huge diff in the midrange and slight increase on top end on the 1100.but i also only run 93 octane fuel.but i ran 89 once with no pre-ignition.

would you guys recommend this for a good mod.

Personal opinion, NO. Big waste of money for very little gain in reality. Put your money into a Factory Pro jet kit instead, along with a slip on if possible and grind the header welds.
You could also do the budget advance mod, do a search, and get the benefits without money outlay.
