I have a Rk-tek head for a 800 Mountain Cat or ZR/ZL. This head has both high and low elevation domes. This head WILL work without a fuel controller box. With the high elevation domes you need to run 91 octane at 6000' and above. At low elevation, if it's ran for any length of time above 5000 rpms, you need to run 110 octane. The low elevation domes, at low elevation you just need 91 octane. I ran this head for over 1500 miles at high elevation without any problems. This Mod is a must! It makes all the difference in the world! Sold the sled, head must go.
1 head and 2 sets of domes $275 + shipping any where in the US.
Feel free to PM me with any questions. Pics can be e-mailed to serious buyers.
Thanks, PIEGUY
