I've recently purchased a 2007 (facelift) 660X and I'm having a few problems.

The bike starts and runs fine on tickover but it doesn't seem to pull clean through the revs, I can only explain it as having a huge flatspot?? If you give is some revs it will go through the flat spot no problem.

Also when its been running for about ten minutes it losses all power and won't start easily, when it does start it'll tick over then cut out if you try to rev it, if you don't rev it then it'll cut out on it's own after about 10 secs??

If i sit there for a few mins it'll finally start and run again.

I know all the usual issues they have as this is my 4th 660X

Any help would be greatly appreciated.

P.s the bike is standard with the exception of Pipeworx cans and snorkel removed
