Gents, Parked up the 630 around 10 weeks ago and all was fine, trickle charged the battery so it has plenty of juice but now the starter turn and the bike coughs but will not start. There is plenty of petrol in it so before I rip everything apart I was hoping there might be a few simple things to check first. I have a 25 ltr safari tank and Scott damper (which I hope I don't need to remove to get the tank off - haven't tried yet). Next stop is try to bump start it, then I guess pull the fuel line to see if the pump is working then who knows. Any ideas of simple things to check before I get the spanners out?
I had similar problem, hard to start, but eventually did. Turned out to be a dead coolant temp sensor. See if it will start eventually without using the cold start lever. If it does, thats it.
If you can put your hands on iBeat it might show something. I agree, it sounds like symptoms of coolant temp sensor. Do you have the stock fuel pump? .
Might be an idea to replace any old fuel in the tank and system with fresh fuel if you have not already done that. I have had a similar symptom. Drained fuel system, refilled with new fuel, and all smiles again. It might have just been an issue caused be the fuel supply system you guys left us colonials, but worth a check Power on regardless
Stock fuel pump in the Safari tank. Haven't replaced the fuel as only been stood around 10 weeks and the BMW fires up first time and been stood longer. Going to borrow a battery that I know is good in case the winter killed mine then next stop try to find somebody with diagnostic equipment and somewhere here that sells coolant temp sensors, not as easy as you think.
