Hi,

MY 650 does not start instantly, but takes 2 or 3 full turns (compression strokes) before starting.
This surprises me since every other vehicle with Fuel Injection and electronic ignition I've tried, usually starts on first compression stroke.

I took the bike in for the 30k service last week and mentioned this, but the service made no difference. The mechanic said "probably due to a weak battery".

OK, so he could be right, but there are no other symptoms and the starter spins merrily enough.

Anybody got another idea beefore I fork out for a new battery?

Mine usually starts as soon as the starter engages. Your problem could be a number of things a weak battery being one of them. Before I forked over money for a new one I would find someone that can test your current one for you.

Thank you Buffalo, I can do most stuff like that myself but won't have time for weeks, I'll see if I can borrow a battery somewhere.

The problem isn't that serious, but if it's on the blink I don't want a failure in the wilderness.

I really wanted to know if the situation was normal, and your reply suggests that it is not.

A worn set of spark plugs can cause this as well.

Like Buffalo's, mine starts almost instantaneously. I agree that having your battery checked is probably a good idea.

I have a 2009 Executive and mine takes a couple of revolutions before it catches like the OP's. I have owned it for a little over a year and it has always started like this. <shrug>

My 09 generally starts a 2 or 3 revs. when cold and generally instantly when warm.

What I was thinking too. Sure sounds a lot more likely to me than a battery. If your battery has enough grunt to spin the engine smartly there should be way more than enough juice to light the sparkplugs. With todays electronic ignitions even a low battery should not have anything to do with out much spark that it is getting.

My '09 650 (3,000 miles) turns over two or three times, quickly, before it starts.

Should start in one crank, in principle. Could be several things -- weak fuel pump, dirty air filter or injector, out of tune engine controls, and lastly the battery.

Four of us have them where I live and they all crank a couple of times on cold starts. 05,06,07,09.

See my signature: "Whir-chirp-chirp, purr..."

Two compression strokes, maximum, when the battery's good. More than that and I start to suspect a weak battery.

Well thanks for all the feedback everyone!
I have the full service history for the bike and can see that the battery has not been changed in the last three years.

Since I no longer have a car (I scoot all year) I need to be able to rely on the Burgy, and since I have very little time available I'll change the battery first (changing sparkers looks to be a nightmare and they are the iridium type).
Personally my money is on the injectors - but I'll bet they cost a pretty penny!

My 07 with nearly 96k starts instantly and has a new battery.

Could also be a starter itself, thou i doubt it
