749 Nightmare to Start

[jangol]

Hi,

Not long had my new 749.. its a 2003 BP...

From cold its a nightmare to start... is this the norm or does anyone have any pointers...


Its not been ridden for a while (due to the weather etc..) its plug into an battery optimiser....

which I'm hopping should be keeping the battery charged...

Maybe stale fuel

Do you know if the fuel filter has been changed? Lots of places quietly skip it as it's a pain to do. But in my experience an old, clogged fuel filter is often the reason for poor starting which wrongly gets put down to battery, plugs etc.

Mine did this even with a fully charged battery , turned out to be a poorly attached earth to the battery. Worth giving it a tug and seeing if it comes off

Thanks will change fuel filter as a start!!

First of all, check (clean and grease) all connectors between battery, relay and starter motor; also clean connector on earth wire bolted to engine and earth wire fitted to ECU.
Next step good battery, gel would be better than acid.

Stuck a set of plugs, cleared out the air filters.. put all back together, started 1st time...

Was over the moon..:)
