Reply To: ST7 (GV650) F1 light due to clutch lever switch ???
Hey Steve,
Clutch Switch will cut sparks off anytime if it plays up, I’ve experienced this myself more than once on my GTR bikes , so much so , that even today we have had 2 orders in wales & dorset for clutch switches to be sent for GTR bikes.
It would be wise to replace it and get 2 of them (1 for spare) , if your local dealer can’t help , just email us.
Keep in mind, ST7s have longer bars than GTs and GTR’s , so don’t try to use their switches as it simply will be 50% too short! – Some terminals may change too!
I would not recommend bypassing it, as fake neutrals “can” happen , so you want to guarantee yourself the clutch is squeezed in before starting.
Also it is very important the side stand switch is Bypassed! (the most annoying object on the bike!) , bridge the wires , and tape it very hard so there is no chance of water invasion , lest it rots the wire and you’re back to square one.
Regulator = I pray the regulator is actually doing 13.5 during idle and 14.5v during 5k revs , otherwise , time to upgrade to shingdens! (Like this one) , the stator too.
Carb bikes can get away with a poorly reg / stator for a short while, but EFI bikes are power thirsty (with zillion sensors all over the place with a fuel pump that draws a lot of amps!) , you want to make sure the charge system is future proofed. Less costly than replacing a delicate fried ECU and ST7 ECU’s are too difficult to buy.
