Another XT700 dyno result
I had the pleasure to test another XT700 today.
This one is running a stock XT660 sleeve, but it was bored out to a 102mm bore and re- nikasiled. I believe it has a 11:1 Wiseco piston in it, with a stage 1 raptor cam and the head was gasflow/ported.
Unfortunately it was running a dynatek fuel injection controller, instead of the powercommander I normally use, so the midrange fueling is bad and resulted in a bit of power loss.
BUT, none the less, this little sucker is STRONG!!!
It clocked in on my dyno at 56.1HP. Yes, similar to what Kev got in his build, but keep in mind my dyno reads lower than Kev's by around 10 to 12%. That 56.1HP on my dyno would give around 62 to 64HP on the same dyno Kev used.
I posted the dyno run of the 56HP xt700X (686cc) in RED and the blue and green lines are from a stock XT660X (blue) and the green is the same XT660X but with DNA stg2, powercommander and Leo Vince pipes. 47HP form a DNA stg2, PCIII, slip-on bike would give around 52 to 53HP on Kev�s dyno.
As you can see, the XT700 destroy the xt660. I am sure with the installation of a powercommander and correct fueling, we can sort out that midrange drop the XT700 has over the XT660 at around 4000 RPM and make it either very similar and slightly better in power.
Wish Yamaha built the XT's like this from the factory.
