XT600E Cutting out under acceleration
Only seems to do it under acceleration, engine stops firing dead, usually about 5000 revs. Once you've lost 20 mph and a couple of thousand revs (if your lucky) it bursts very suddenly back into life.

No splutter cough or hesitation, it seems electrical, on/off like a switch.

Any ideas what it could be?

Thanks

Suspicious #1: Sidestand switch. Disconnect it from harness and connect the two wires from the main harness. Good luck.

This sounds EXACTLY like the problem I had with my 600E.

In the carb, under the float valve, there is a little fine fuel filter. This gets clogged up and stops the carb filling up with enough fuel to accelerate.

It should be checked/cleaned anyway so definitely check it out as it's an easy fix.

It's the same on the TT600R - it is a tiny thing that doesn't have much surface area, hence the clogging.
Ditch it and fit an inline fuel filter upstream of the carb. is a good solution.

Thanks folks. I've posted on a couple of other forums too, and the carbs do seem to be a reoccurring theme, though over on the ABR forum people are pointing at the secondary carb not the filter.

I am reading about the YDIS carbs as I'm not really sure I understand exactly how they work and how the secondary carb is bought into operation (I assume it's intake vacuum pressure?). As I understand it it's basically a standard CV carb, with an SU carb (the only one of those I've ever stripped was an Austin Maestro!) bolted to the side?

I've plenty of time to learn, etc, because the bikes for me are toys and I have two cars. I'm soon to move house and my next few weekends will be taken up with packing and moving, then by the time I've got that over with, I'll be getting my Triumph Daytona out of hibernation for summer, so the XT is going to sit in the garage for a couple of months until I get time to look at it.

Yeah it could be the secondary. If I remember correctly the second carb opens under vacuum pressure. Check all the little rubber hoses don't have any holes in them.

Also, there is a rubber diaphragm in the carb which may be in poor shape.

You should be able to lift the carb plungers up with your finger and they should fall back to their resting position smoothly..

Cutting out
It may also be worth checking the carb inlet manifold as the rubber sleave tends to part company with the aluminium base, this allows air to be drawn in through the split rarther than the carbs (worse at high revs), take a close look it is often not obvious.

You have time on your side so I suggest you download the manual for this bike which is available in a sticky at the top of this forum.

I used a similar manual for the TT600R when I owned one of them and it is amazing how much I have forgotten!
The workshop manual is a great read &

Yep, already got it thanks mate.

What I'm not sure I have is an up to date wiring diagram. The one I downloaded when I got the bike shows shows a CDI unit, mine will have a TCI unit.
