check gas cap to see if it's bad check to see if it's vapor locking

Take the bike out for a ride and when this happens pull over and open up the gas cap. If it starts back up and keep on running then you have found the root cause - your gas tank's vent is clogged, you will need to have it cleaned out and serviced. Basically a clogged gas cap vent causes the bike to vapor lock and prevents fuel from flowing.

alarm! immobiliser?

If it runs, or at least wants to run when using the starter fluid, then I would think that it is a fuel delivery problem. This could be a carb problem (blocked jets, incorrect settings etc.) or that the fuel is not getting to the carb (blocked filter, line, faulty fuel tap). Make sure plugs, air filter, fuel filter and fuel itself are all as they should be as often it is the little things that are the main cause of problems.

Hi Tony what was problem with original ECU? They don't usually cause this problem. An ECU either works or it doesn't check the plug and lead to see if they are breaking down and allowing the spark to jump. Regards Jim...

how to turn up idle on 2008 Mini Cooper S

The bike has a sidestand interlock that prevents you from riding away with the kickstand down. That interlock is not functioning properly. Could have been bent or moved, unplugged, or perhaps the relay has failed. If physically activating the switch does not work, and connecting the wires with a jumper does not work start looking at the turn signal relay, some bikes have that circuit integrated into the relay.

Most of the safety systems use a diode pack in the loom to stop clutch and side stand switch etc from back feeding each other. Maybe this has failed. If not could it be in the loom, a broken or shorted wire. Look for a tight bend in the route the loom runs and external damage to the tape.

Check out the side stand safety switch, check if the switch is sticking remove any grease or dirt that may prevent the piston returning

I would suspect you have an ignition problem. Diagnosing over the net is tough without hearing and feeling it - you know what I mean. Is there any recent history with the bike - was it layed down, worked on, modified, run really hard, has it been in storage - what kind of recent history do you have for this bike?

Clean or replace air filter..then if the doesn't do it, go to Autozone and purchase a can of Sea Foam fuel treatment and pour in 1/3 can to 2 gallons of fuel, purchase or clean up your fuel filter and then dump out the fuel in it, now pour some Sea Foam into the filter and then start it up. if it doesnt start up, then push start it, and get on it and go! Ride for about 10-15 miles on and open highway where you can get on it occasionally to let the stuff work its way through the fuel system. If this did not fix it, then check all your vacuum lines, spray around the carb areas and lines with some carb spray, if the rpm increases ..then theres your problem. Can you rate this! thanks

ceased or your rings have gone an got stuck in your piston barrel
