Well I almost bought a Kingquad 750 but came across a used 06 700 Kingquad. Had mudlight XL, clutch kit for (larger sized tires) although 25 " mudlights are on the Kingquad, and a copperhead VDI. Question is that I dont see any differnece in the low end, mid range is slightly better and top end I am slower (64 mph) was my fastest run in about a quarter mile. Its my understanding that there are different maps to download in this copperhead VDI. What should I expect and is there a certain map I should put in it. What is the map? Also i read there is a fuel injector that will enhance the VDI? I looked up velocity devices and was going to send an email with my questions but for some reason I could not open the email address.

Raced a stock 07 700 King and I beat him slightly at take off but he pulled away from me early in the race. 06 650 Can Am just whooped both of us by about 3o feet. Well any information will be greatly appreciated.

 

i just bought my copperhead ECU,havent got installed yet but when i ordered it they asked what size tires im running so they can program it to that size. This may be why its running slower. If it had larger tires on it and a clutch kit, it may have the copperhead programed for the larger tires.

 

well i wouldnt worry about that too much, cuz ur gonna have no problem whooping him in the long run (reliability) and in any real offroading
