Blueproof mod gone bad - SV650.org

07-08-06, 12:21 AM

I completed the mod. But not she wont start up. I turn the key, get all the lights, then when i press the ignition. It does nothing, like if the clutch wasnt in. Is there some safety I'm forgetting. I put the airbox back on, closed it up, and it still won't start. I checked the fuse, its fine.

the bluepoof carburetor mod is this,

I recently was talking with northwind about it. The kill switch is the red button next to the throttle which cuts the engine out. When enabled, the starter does nothing. Maybe you call it something different on the other side of the puddle.

Yep, that's the killswitch they meant, and you just described the problem you have, so is the killswitch set right? You wouldn't be the first.
If it feels like an interlock is stopping it starting, then that would seem like the most obvious place to start looking. There are interlocks on the clutch, the side stand and the killswitch.

Trying to think what this could be... The actual work you were doign doesn't have any part that ought to kill the bike entierly, I think- you could leave a bit off and have it not run, or run like a sack of spanners, or bump a HT connector, but nothing that'd stop it from turning over entirely as you're not messing with the electrics at all.

I wonder... Sidestand cutout switch runs up the left hand side somewhere, can't remember exactly where but I don't think it's far off where you were working. Possible that it's been bumped The clutch cutout is pretty much seperate, and I don't think there's any likelihood it's been bumped loose in the work you're doing- runs on very different lines.

Maybe this is related, maybe not. But it seems my horn no longer functions as well. Are horn and starter on the same circuit? Is there a ghost in my machine?

Check that when you disconnected the circuit that connects to the throtle position sensor, that you did not disconnect any other wires running down the side of the bike, there is also a couple of connectors in front of the carbs, check them as well.

Start with the clutch safety, make sure it's in neutral, check the sidestand safety. Still nothing? Look at all the connections between the airbox and the engine. Could you have dislodged one of the boots making a huge vacuum leak? Are you sure you haven't removed the vacuum from the petcock some way? On first generation bikes the vacuum also powers the fuel pump.

Retrace your steps.

I read the referenced instructions and have two comments:

1. If you are using vacuum gauges they will bounce a lot. You can buy in-line orifice restriction tubes from the local auto parts store in the same place they sell automotive tubing, tees, connectors, etc. The orifices help calm the bouncing. You can also pinch the tubes a bit.

2. It does not matter how long the tubes are nor how long they are relative to each other. One can be an inch and the other five feet. Won't matter. Try it out sometime.
