Tried to start my SP2 the other day after it being left in the garage on paddock stands for a couple of months. The engine turned over ok but coughed and sputtered a lot and when releasing the start button the engine stopped. If i opened the throttle a bit it would run ok but again releasing the start button the engine stopped. The only way i could get it to run was to press the start button, open the throttle to get the engine to run at about 3k rpm and then release the start button. Took a few attempts to get it to run. Once it has been run for a while it would start straight away. Anyone else had this issue?
Is it a low battery voltage issue? Did you add any fuel stabilizer before you parked it up? They would be my initial thoughts. Try putting it on a battery tender, and putting some fresh fuel in it (if possible).. ie if it is half full, fill it to the brim with fresh fuel.
I do keep it on a Lithium Optimate all the time. The engine turned over ok but just didn’t want to run when releasing the start button. I have never done anything to previous fireblades when parking them up for winter and they have started fine after too.
I started mine after 2 months and it took circa 10 secs to settle at a decent idle. I would guess that it would be fine after a decent heat cycle, and been out for a run. Mine has fuel stabiliser in now, and waiting for weather to warm up.
No mechanic but it almost sounds like the starter motor wasn't disengaging? Not sure how the starter works on blades as never bothered to look but maybe the spline may have been a bit rusty if been damp and wasnt easily disengaging so when you release the start button the idle wasn't enough to turn the starter motor over and the engine? Just thinking out loud after a few beers
how about the fuel going off? specially if your tank wasn't full and your garage humidity level is the same as your outdoor which has been 90~100% in england since october
Also summer fuel chemistry is slightly different to winter one which I beleive is more volataile. doing a full ecU reset may also be a possible solution
Thanks for the replies. I guess the fuel could have gone stale just never had this issue before with previous 2012 blade. I’ll start it up a bit more frequent and see how it goes. Cheers
Tried bike again at weekend and this time it fired up straight away and ran perfectly. Looks like i need to not leave it for too long between start ups.
