I have a bit of a problem. I've just picked up a second hand 2005 VStrom - it had a few issues like a sticky ignition but nothing too serious.
After a few days of riding it started to refuse to turn on with the F1 error. I read here how to put it into dealer mode and read the codes it was sending: C41 (Fuel Pump Control System (Fuel Pump Relay)), C44 Heated Oxygen Sensor (HO2S), C49 (PAIR Control Solenoid Valve).
I called recovery who prodded around the bike but they couldn't get it to reset - disconnected the battery and reconnected to come back to the same errors. Recovery brought it home.
I couple of days later I go back out and try to start the bike - it starts fine.
I got a friend to have a look and found the voltages in the battery were a bit low, so we replaced it with a new one. We found that we could replicate a similar condition reliably by turning the bike off with the kill switch (something I never do normally.) After a few seconds the error code would pop up C32 (Injector Signal #1 ( Front)), C33 Injector Signal #2 (Rear), C41 (Fuel Pump Control System (Fuel Pump Relay)), C49 (PAIR Control Solenoid Valve.) These errors could be cleared by turning the key off then on again.
We looked at the other kill switches in the kickstand and the clutch. The kickstand kill switch had the same effect as the red kill switch - same error codes, same ability to reset with the key.
The clutch killswitch did nothing, the bike starts with the clutch out - the switch must be broken.
I brought the bike home again and everything is fine - I'm feeling pretty good about it. Hard learning in brain to always turn the bike off on the key.
Next day I go out to put some GT85 into the sticky ignition and boot (gotta pull the key towards the handbars to turn it.) I try to turn the bike back on and get an F1 error.
I flick the kill switch on and off, nothing, I play with the kick stand and the the gears, nothing. I eventually disconnect the clutch sensor - and the error clears, bike turns on.
I turn it off, turn it back on and it sometimes errors out, sometimes fires up - connecting and disconnecting the clutch sensor stops having an effect.
I get the bike running and take it out for a half our drive - after about 20 minutes when I bring it up to traffic lights and it goes idle it starts struggling and eventually stalls. It might be the dying grumble of the engine and a compelte red herring but I'm pretty sure I can hear the (I'm not going to guess what it is, it's the pump that whines for a few seconds when you first turn the key - fuel primers?) going which is a sound I don't usually hear. Might just be drowned out by the engine usually though.
This is the first bike I've owned - I had a feeling I shouldn't have brought privately first time round due to my lack of knowledge but it was recommended to me by someone who knew the bike. I'm an engineer by trade so know my way around a multimeter, but have never dug around in a bike before - I know someone who maintains his own bikes and has offered to help, but he's never worked on a VStrom. It's booked in for a service but the mechanics are all booked up for weeks so that's a long way off.
Any help or recommendations of what could be wrong would be greatly appreciated.
