Need help !!!!
1.Have a 93 R1 ,when driving the car breaks down as it starts to boost.Initial start up the car will rev clean off load but as soon as it warms up it will start breaking down at 2500rpm and higher.When driving if i cut the ignition and switch it on the car will boost to.4bar and straight away start breaking down.I have replaced all the vacumm hoses and removed the emission solenoids (no emission laws in South Africa) but still have had no luck.
2.where is the check engine light located ? ? ? ? ?

Any suggestions would be appreciated .

The check engine light is on the instrument panel toware the lower left corner (right next to the seatbelt warning sign) You should be able to see it light up every time you crank the engine.
What kind of vacuum are you pulling at idle??
