It obviously sounds like its being starved for fuel, you said that you replaced the pump and the filter, what about the carbs ? has anyone checked them out ?

If the bike has been sitting over the winter and the carbs were not drained or if the fuel wasn't stablized then you might have some dirty carbs, you can try draining the float bowls and then adding fresh fuel see if that helps, if not you'll likely have to pull your carbs and clean then. Todays fuel doesn't las that long before it goes bad.

The pilot jets need to be removed and cleaned along with all internal passages. Boil the carbs in lemon juice, check float heights, new o rings, sync and you will be good to go...

Troubleshooting moto guzzi stone


Just a thought as you asked...sounds like a poor throttle position potentiometer ... throttle cabled to butterfly most likely and if ECU dosen't know throttle plate moved you will see this symptom . If electric throttle , can you see(hear) plate moving whilst twisting , if so measure resistance/voltage on pot. . I do not know if resistance of position sensor can be measured while twisting throttle or pushing plate (bike off , battery disconnected or ignition off)

With the engine ticking over ,then when pull I the switch to run the blades the engine stalls. What is the problem.


Hi. You have to increase the throttle to about half before you engage the blades otherwise the weight of the blade assemblies will stall the engine. I hope this helps. Regards Phil.

Bike starts fine on choke then ticks over when choke off. within 2-3 mins the revs decrease to the point of stalling. have adjusted tick over to around 900 revs but as soon as engine warm the problem re...


If your bike has ever sat for more than a few months at any time, the carburetors could be plugged with gasoline residue. If so, they will need to be disassembled and cleaned.
Otherwise, make sure all of the normal tune up items have been performed; valves adjusted, air filter, spark plugs, etc. And make sure there are no air leaks between the carburetors and the engine.
Finally, if the above things are all good, then I would perform a compression check. With the throttle held wide open, you should see at least 140psi of compression, on every cylinder. Anything lower than that will cause an erratic idle quality and overall poor performance.
