RE: KMP F-7F Tigercat

I have a set of OS 120 sp (super charged) 4 cycles that I was thinking if I got sick of the E setup I could put in my Tigercat but it would be a minimum of 3 less HP and that would make me sad. :(

RE: KMP F-7F Tigercat

I just bought my 2nd NIB OS 120 SP. It’s the best 4cycle I have ever owned . If I get tired of the electric set up on my t-cat I might do an electric to glow conversion!
