want to get a big bore kit, which one? looking at hpd 558, nicholas cycles 558, or hotseats 600cc, who has one and how reliable are they? i have a pipe, hotseat intake kit with 210 main jet, with procomm cdi. i can hang with yfz but not the retarded cam yfz's. want to run with them , thanks.

 

nicholass cycle.....i have the stage 3 kit and it's crazy quick!!!!

 

From what I hear Nicholas Cycle is the Predator horsepower king. If you want to be satisfied I would go with Nicholas and stay far far away from Hotseat. My experience with Hotseat customer service was extremely bad.

 

the hotsat 600cc kit is good, just you need to send it to doug to install cause it needs a few other mods to get the most power!

 

I would also say go with Doug's kit.....he will give you everything you want, including customer service......He will build it to your wants/needs too.



If you want real power, get the falcion kit.......I think it is a 627cc.........Doug will build that too.......
