Hello Kev,

Just installed the stg1 cam and the PCIII,OHHHH man the bike is great a lot of power in mid going all the way to rev limiter,there is a loss in the botton but nothing so bad.First I`ve installed the stg1 with the Kev mod and went for a ride the bike runs well but with a lag in acceleration between the mid to the top so i�ve installed the PCIII with the CCC big bore Frans new map and the bike got worse than with the Kev mod felling to rich I thing because the comsumption was too much ,so I send your custom map XT700 big bore +stg1 and guess what the bike is great smooth no lag in acceleration and fuel comsumption is in 20Km per liter can you believe it.I will dyno my bike soon to see if the the guy can make a better map that I thing is difficult, the bike is almost perfect pushing hard and smooth at the same time with a incredible fuel comsumption. the bike one time hited the rev limiter in 5th gear 190Km for my lucky I weigh 60Kg This make some difference

Very good news.

I will move this thread to the main forum from the Ask Kev Section for everyone to read.

I new the Kev Fuel Mod would not work with a high lift Cam & did mention this to you before, but thanks for trying it anyway & reporting your findings.

You must remove the Kev Fuel Mod & only run the PCIII.

Please post the dyno run results with HP & Torque & send me your custom fuel map once it has run on the dyno.

With this Stage 1 Hot Cam my bike starts to pull hard from 4500RPM all the way to the rev limiter. My top end is reach very quickly, normally from 95MPH the pick up is very slow, now it just pulls hard all the way to the rev limiter.

Can you also list all the mods on your bike as well as your ECU number, so we can give everyone the full picture on how your bike goes with all it's mod on the dyno.

Well done.

Yamaha should release the XT like this from factory a lot better i can say exciting .As soon as I had my bike on dyno I will send you the map and my bike specs,The bike is so great that i�m afraid the guy mess up everything ,but I will run the bike on dyno like it is and see result,and then make the new map to see if there is some gain.

Hi there,
I see all the pictures and you writes, I have xt660x too, but how can I find hot cams??? and I visit hot cams page I didn't seeanything about xt660
who help me about the high lift cams???

You need to buy a complete Raptor 700 camshaft with sprocket & decomprssioner, then you buy a Stage 1/2/3 Raptor Hot Cam off Ebay & fit it to your XT660.

I have a complete Raptor camshaft for sale if you are looking for one.

This is how it is done.
