Hi all, I am the Slightly younger and shorter brother of Ace2479.
I have also finally got an XTX which I purchased 2 hours ago.

Its a 2010 model in black, will post pics once ive cleaned it.

It was a pleasant ride home cosidering it was mostly M25 and very windy, happy to sit at 90mph all day and almost no vibes. But............................. the jerkyness at slow speeds in any gear is unbearable, coming up to junctions or steady 30 - 40mph driving is horrible and I wont even mention roundabouts.

That alone makes we want to get rid already but I will have ago at ironing this out with your help. As far as I know its all standard apart from dual MTC cans, there is no popping from these (well at least with the baffles in anyway)

Can anyone help me or advise me on what I should do first to maybe get rid of this snatchy riding lol

Also the bike has 8 months warranty left with yamaha

Thanks in advance

Ok rang the dealer today, who said the bike is perfectly normal and not to worry about it, they all do it. Also said never to touch the TPS.

I said its very bad, so he said is there any mods, I said just the MTC cans. So now he said its the cans making it ride like this need a PC3.

Sounds wrong to me.

He said bring it in next week and he will test ride it

Sounds to me like your mechanic doesn't know his ass from his elbow mate....

Thats exactly what i thought to myself as soon as I put the phone down.

Would really like this surging gone.
What should I start with first, maybe the CO from the dash

I need your expertise

Hi bro,
i noticed that when i had ago its worse than mine,
what did you mean by playing with o2 is there something on the dash you can do, and was that the YAMAHA dealer that said that ????
somewhere on here is how the site started its an interesting read bro also said something about that serging when i find it again i will send the link, hope you get the help you need and quick lol,
laters and peace out

Step 1 - Join the XT-Supporter Scheme see how here http://www.xt660.com/showthread.php?t=1475

Step 2 - Send a PM to Kev and he will sort your surging out in the cheapest way possible with one of his inexpensive Kev Mods and a few tricks to apply to your bike settings.

Step 3 Ride away and enjoy ever after.

Yeah bro that was keys motorcycles.

Captmoto, Step 1 was the first thing planned for payday lol.

But yes I have read that there is a way to change the CO on the dash and has almost eliminated it but cant find it now.

Hi and welcome to the forum

think this is what your looking for

The CO settings do help but the best thing i found to sort out the fuelling was a stg 2 filter and kev fuel mod.
