Kfx 440 bg bore

hinebaugh5 · #1 08-09-2007, 03:34 PM

I was thinking about putting a 440 big bore on my 05 KFX and im not sure what the best compression ratio would be for me. Ive been looking at the 12.5:1 and 13.5:1. Im not that serious of a rider but i do enjoy racing on occasions. If im not racing i still usually ride a track but also ride trails alot. any suggestions would be nice thanks.

You can run high octane pump fuel with either one. Go with the 13.5:1 for a little extra snap.

Sorry, I'm not horribly familiar with quads stuff, but you can't really go wrong with a good company like Wiseco. What are the other options?

You might also think about just upgrading to one of the 450's.....

Might save you money in the long run..
