My 630 is a pig to start, recently draining the battery. It wants to go, but doesn't. I'll look at the spark plug, and have been told a water temp sensor could be the issue. Anything else I should check for? Also, what's the lever on the left near the clutch. I've been told 3 answers. A hot start, a choke and a decompression. So what is it?
The small lever on top of the clutch is an enrichning lever (some call it a choke) When starting cold pull it all the way back then engage starter button. Because your having a problem starting it use jumper cables from a car battery. Possible weak battery. Check for enough gas in the tank. If you can hear the fuel pump pressure up then quit it should start. Later George
Starting lever.Mine i just pull it in and hit starter button and it fires up.But i to had an issue where it wouldnt start.This went on for days it was a cow to start,then one day i turned on ignition and fan came on and neutral light was flashing,when it was stone cold.TEMP SENSOR.Now sorted.
Does it fire at all? If not, pull the plug and check fire. Do you smell fuel in the exhaust after trying to crank it? If you've got fire, and you've got fuel, chances are the temp sensor is going bad and leaning it out too much.
If the radiator fan runs when the bike initiatally starts (cold engine operation) the temp sensor is bad and causing your starting issues.
Mine used to just popped and farted when starting,and was a nightmare to get it running. But then a week later it developed into as Fast1 has described above.
Infact the part number has changed on the temp sensor,i believe there is an updated one.Someone on here will verify that.To be fair well worth fitting one ,not dear and a 5 min job.
The 630 is normally a fast, easy starter. I have never needed the start lever (on the left) it starts at the first touch of the button. If I had a problem, I´d look at those useless safety switches (on the stand, clutch etc.) to see if they were the issue.
Here in NJ, my 630 only starts up on cold (50-degree or lower) mornings when using the fast idle lever on left side. I also have the oem battery on battery tender when in garage.
