Here is the background info and the general issues around this bike up till now
Had a lowside last year and ever since the bike has not been quite the same again. The damage was mostly cosmetic with no major mechanical issues.
The stalling issue has been getting progressively worse, but that issue has raised its ugly head from before the low side.
I have now performed a major service on the bike including:
- Setting the cam timing using the OEM factory service tool (The cams were off by 1 tooth by the way)
- TPS set
- Throttle bodies balanced
- CO set at 4%
- Valve clearances checked (everything is within factory specs)
- Exhaust leak (slight blow by on the one pipe connecting to the back box) fixed
- Oil, filters, plugs changed (NGK CR9 plugs)
- The plugs showed slight richness but the end can is dry black
- Slight slack from throttle cables removed
- Battery is perfect
- Checked each and every electrical connection and cleaned her up.
- Idle is set at 1300 rpm
- Timing sensor gap is as per factory spec
- Fixed the fuel pump electrical connection (my fault)
- The bike will not run properly!!!!!
The bike will not start unless it is in neutral. No matter what position you have the side stand, unless it is in neutral it will not start period.
Once it starts up, it will either fire up on the first go – or it will turn / start to catch then die down, then the starter will automatically kick in and start up again and this cycle will continue until you crack the throttle a smidgen – the bike will either catch and idle or it will suddenly die like somebody smacked a piston with a 20 pound hammer on the upstroke. It is almost violent the way it stops. You can physically hear a soft metallic clunk as it happens and the compressed air escaping is audible for a couple of seconds
You push the starter button again and the cycle will repeat or it will start up and purr along with no problem in the world without you having to touch the throttle.
Once the bike is on idle you again end up with one of two scenarios
It idles perfectly and when you blip the throttle it will jump up in the rpm range and settle back down again or
The bike will do the violent stop stunt again
Put the bike in gear it will either run smoothly sometimes,
Or it will immediately do the violent engine stop as you put it into gear or as you start to pull away
You have to put the bike into neutral to start it back up again (and the first scenario then repeat itself again starting the bike) The bike will not under any circumstances start in gear.
Once you get the bike up and running it will either run smoothly, or you guessed it. The bike will do the violent engine stop as you change gears regardless of what speed or rpm you are at.
What am I missing? Why would the bike progressively become worse until it ends up in this state?
Any help or suggestions appreciated
