Hi All

I'm a new owner of a 2013 XTX. The bike is brilliant and great fun but as many others it suffers from surging a lot. I've been reading through posts and mods on this forum in the past few weeks and the tips were very helpful, thank you.

I bought the bike from a Yamaha dealer with only 2400 miles on it, had 2 previous owners and had Leo Vince exhausts fitted. According to the dealer this was done at the 600 mile service. The bike was always service at the same dealer.

Last weekend I tried the CO mod and I've seen that it was set to 19. I'm wondering if the previous owners played with these settings as it seems a little high (according to other posts).

Is there a way to reset it to it's factory settings?

By the way, I upped the setting from 19 to 22 and it feels like that it made a small difference. Now it looks like that the surging has "moved" from 10-30 miles range to 20-35. I'd like to up it a bit more but want to find out first if it has been modified.

Also, how high can one go?

Thanks
