Yamaha XT660X - who's got one?

[titirangi]

Well the results are out for the XT700 conversion, I am still testing a few different camshafts over the next few days, so more dyno sheets to come.

Those charts look great. What sort of difference has it made to the ride?

Have you ridden the KTM prestige - I wonder how this compares power and flickability?

I also wonder if this mod would affect the fuel range as I am looking for a daily commute and this is important to me.

Great work - really helpful to motard noobs like me, cheers.

The bike pulls real hard from the mid range all the way to the rev limiter, loosing only 2HP off peak power at the limiter.

I am back on the Dyno tomorrow testing different cams, I am looking for more torque in the low to mid range.

I have not ridden the KTM.

I have a LCD Dyno jet display & can change fuel maps on the run at any time or speed, it can store up to 5 different fuel maps. I have set up 2 different maps for this mod, map 1 fully mapped between 12.8:1 to 13:1 air/fuel ratio for best performance & map 2 good fuel consumption 13.5:1 in the mid RPM range for work & back.

hi guys,

I am really getting desperate with my new XT660X 2008 and I hope someone can help me

2 months ago a problem begun and while I was driving, the bike was choking like it was going to go off and then switch on again... I took it to my mechanicer and put it on the computer and found that there was a problem with the ECU... 6 MONTHS OLD BRAND NEW BIKE AND HAD A PROBLEM WITH THE ECU
Anyway, he fixes that and the bike was fine for two months or so...

Yesterday however, while i was driving again, the rpm suddenly increased and whenever I left my hand off the handle, the rpm were still high... I am not happy at all until now and I problem keep coming i will have to sell it...

The thing is I dont want to because I love driving it... It is so fun to drive...

my mechanicer is really testing my patience telling me that I am stressing too much.. I wouldn't be F****** stressed if you fixed the problem and pay attention to my concerns...

Anyone having the same problem?????????

Throttle position sensor. There was a recall on earlier bikes. Simple replacement, should be under warranty.
