View Full Version : Bad Habit or problem with the bike - engine dies.

I need help with this one:

Sometimes, when I am coming up to a junction with the bike in second and clutch pulled in coasting along, the bikes rev's seem to drop and very occasionally it stalls. I really am struggling to replicate it, but just as I pulled into my drive this morning it did it again. I can't work out if it is something I am doing or something with the bike. i.e am I letting the clutch out slightly. However it does not jerk it just slowly dies with the revs dropping. It only seems to do it when I am coasting up to a junction.

Any ideas anyone?

Why are you leaving it in second? If you're going quick enough to be able to pull out of the junction if it's clear then I'd have thought you would want to keep the clutch engaged, if you're planning on stopping, or almost stopping before being able to go then why not go down to first?

I suppose it might be down to some clutch drag, does the engine still die if you knock it into neutral?

Yes the engine still idles when knocked into neutral, what are the symptoms of clutch drag and what is the remedy?

When stationery and engine running in neutral pull the clutch all the way in and put bike into gear. Do the revs fall and the bike feels like it's trying to go forward? Another easy way to spot it is it's hard to find neutral with the engine running and the bike stationery.

I know this is a slightly tangential answer, but I wonder why you're coasting in second? I only ever coast when I am in first and just about to come to a complete halt (so I coast for all of about half a second). At all other times, I've got the clutch at least partially engaged. The only other times when I coast are by accident when I either find false neutral (which seems rare), or the bugger pops out of second into neutral when I haven't kicked it up hard enough (not so rare!)

It can be down to your idle speed being slightly too low.

Can also be down to running a bit rich, but if it runs fine in neutral then probably not this.

Curvy or pointy?

As said, what's your idle set to? Might be too low.

I had my curvy doing something similar when I forgot to switch the choke off.

It's an 2010 Pointy so as far as I know there is no idle adjustment?

What is the idle speed in neutral? Does sound like clutch drag, also sounds like the bike is almost new so you could ask the dealer if they'll adjust it for nowt. There are two adjustments, the lifter itself (this is done once in a blue moon so should have been done properly when it was new, but who knows) and the cable, which is for you to set as you feel most comfortable as long as it doesn't slip or drag. Anyway try winding the cable adjuster (handlebar) out a turn or two and see if it makes any difference.
