GRiSO 1200 non start

hi guys, can anyone help please ? bike was running fine when i last used it, i put it in garage, lifted it up with hoist with bar in center holes, cleaned it,and covered it up, went back to it today, but it turned with starter, but did not fire, i tried this three times, now it wont turn over, the battery is fully charged,(on constant trickle charge )i can hear the start relay working when i press starter, also, the lights are not on when ignition switched on ! i have tried disconnecting battery, but makes no difference ! any advice greatly appreciated.

When you hit the button does the dash blank out?

hi pete, no, dash stays same, the stater relay clicks goes off after about five seconds ! i wondered if it has an angel bank sensor, and i upset it when i raised bike ! regards, john.

Check the main 30A fuses but otherwise it just sounds like standard 'Startus Interuptus' add a direct feed to the delivery side of the starter relay.

IIRC, when the tip-over sensor is active, you don't even get a 'click'. However, it's always been after I've dropped the GRiSO, so I'm not sure that's a reliable statement. I always need to release the pressure in the tank as well after a lay-down.

You say the head light isn't on? Bad relay or blown fuse.

Had this problem before and positive plug on battery wasn't making a solid connection/blown main 30amp fuse.

headlight will not come on until the engine is running...

That is incorrect, Tony.


The headlight assembly consists of two lamps. The main beam (item 4) is active after the engine starts. The parking lamp (item 5) is active at key-switch 'on'.

Only the pilot/park light comes on with the ignition. Main beams don't kick in until the crank is spinnin'

Still part of the headlight. fuquen semantics.

He said 'no lights come on'.

Pedants.

shit, I'm outa here - you blokes wield razor blades pretty well.

That's us!

Fixed it anyway!

I reserve the right to be contrary. And cut you.

thanks for all the suggestions guys ! it was the parking lights that were not working, i checked all the fuses, and found fuse B in box was blown, this is for parking lights, passing, and ignition relay ! i replaced it with spare 15 amp fuse, and it was ok, i tried a few more times, and it blew again, so i need to check wiring to see if i can find the fault, but its good to know its nothing too serious, regards, john.

The ecu on my former 85 K100 would not turn the fuel pump on without the minimum voltage being present. Bike would turn over at a slower speed than full charge but no ignition/fuel. A "safety" failsafe I think. Trickle charger during storage can also help prevent the 'cobwebs'.

Blades coming---------------------------WE DON"T CARE ABOUT BMV's, junk shit.

I believe in free speech. How's your COVID lockdowns doing? Your country was a lot better in 1980. What happened? Don't cut yourself.
.

The two control systems are completely different which means that something that one may do as part of its engine management may be utterly irrelevant to the other. That is the case here. Although, as I understand it, there are a lot of similarities between the Bosch and Marelli systems there are also major differences. Especially when talking about generations of controllers separated by decades.

Stop dragging up 8 year old threads for no valid reason.

You lot are legends. I just had the same problem. My battery is original (2012 SE) so I changed that, no luck. Read this thread and fuse B blown.
Not bothered re the new battery is was well over due.

Thanks Pete. I saw your box of cams , tappets ,and shrapnel. There's nothing I can say to make this better. I will pm you when I go through this bike . There's nothing I can trust from one end of it to the other. But I love it anyways. AF 1 is 1.5 hrs away and this bike is now capable to get an appointment. A couple more things to check out first. Yes. The engine heat sensor is flat out gone
Nothing but a threaded hole where it should be and yes the Service light has been on constantly since I bought the bike. Back yard Harry just shrugged and you know the rest.

In all honesty I'd just part it out and purchase another machine.

It's been so thoroughly fucked about that it will not be economical to recover it. New throttlebodies alone are $2K+ then there are missing sensors and stepper motor, a hacked up loom by the sound of it. God knows what else will turn up.

We both know that would be the ultimate end. But I'm stubborn. I'm a bit fascinated with the injection and will tolerate the warts and scars of its previous life. I will buy the heat sensor and wire it back in if necessary. I can relocate that racey catch can as it is doing its job with no drool from the vent end and the entire engine exterior is dry as bone. The brakes are the best I haver ever had and the rear brake is set right to not swap ends. I use a medical cardiac stethoscope to listen to all sorts of things. It is really useful for throttle plate settings and idle air flow. The priority of noise is in the ears and not all the other engine sounds you would normally hear without the scope. Yes you can sort of do this with a long screwdriver touching the different areas of the engine but not as well. I listen to combustion as I make adjustments dull and rich to sharp and lean. No. It is not as accurate as the computer screen but I get it closer than the botch job it was. Keep in mind they (the manufacturer) do NOT want anyone changing the sealed engineering that is usually set to lean and clean. Guys like me are called "nut tweekers" quoted from a Kawasaki engineer at a big bike show. I drilled and pulled the plugs pressed in over the idle mix screws on my Concours and found none of the carbs matched each other let alone all four balanced. So I will learn some new stuff and use some old school. I have full title in Texas now on this bike and when I sell it my log book will go with it. But I am enjoying the beast as it has a lot of potential.

Please, anybody else reading this. Under NO CIRCUMSTANCES should you attempt to 'Tune' your fuel injected engine by any of these hare brained methods.

You cannot  'follow me. No disrespect  to anyone reading this. I am not looking for arguments or attention that I don't get anyplace else.  For some reason I am intrigued  and challenged by mechanical things. I could give examples but I  have met very few people that are as mechanically "reckless" as I seem to be.
 Why would I take a match to an intact motorcycle;  or any other thing that seems hopeless to those that feel helpless about a situation?  Before I give up I will modify to make it simpler and perhaps better...for me. There it is.
The only person at the controls of anything;  you see in the mirror every time you look there. I would not change any of my try and fail to walk a straight but narrow path. All of the bikes I have,  have been given up on by some previous owner (s). Each one of them is different in many ways. Just like us. There is nothing new that hasn't  been tried before. Then there's  combinations of what could be. Look at music. Combinations of known notes that continue to create something new.
