This might be incredibly obvious, but are your valves too tight? My V65 (which is similar in some ways, not so much in others) would exhibit the exact same behavior when the valves (exhaust) needed adjustment. As the engine heated, they would tighten just enough to kill it. After a hard run down the mountains, I would arrive at the base and stop at a stoplight, the iddle would hunt down until it stalled.Adjusting them to the loosest spec would remedy the problem for several thousand miles
Both air screws should be bout 1/2- 3/4 open not just one. Maybe TB's are dirty, if airscrew is all gooed up it will be worse when cold.I clean my TB's every 10Kmi, it makes a difference. Make sure valves are set at .006" intake & .008" exhaust, not 4 & 6.
I suggested to him checking the stepper but he replied to me that in this bike, with 19.400km, it's hard to believe that this is generating the problem.
Stepper? Like an Idle Air Control valve?!?Because there isn't one on a 2TB smallblock. That's why you have a fast-idle lever on left grip.
Ups! I expected to have a stepper valve. So does the idle relies only on the air intake by sacred screw and bypass? Usually adding a little fast-idle lever fixes the problem. Thanksfede
Make sure you are looking in the correct bike manual like Kev says, it is not like the other Guzzi's of that era. More like a California model.That's why I mentioned the Valve setting, book say's one thing but it is too small and finally updated in 2012 or so. The mechanic should know that if he's been at dealer for a while. For a higher idle you could open airscrews equally a bit like 1/8 turn more, usually done w/carb sync attached so to be equal. Make sure they are not closed. It will run rich mixture when closed.
Did the shop check the fuel pump? Especially the 1/2 plastic fuel filter. Fuel filter should be an all metal one. Some had a bad fuel line that would slide off pump. Sounds like it runs out of gas & dies or fuel pump shuts off.
That was in a bulletin here to swap out for a blue/orange one. Free from importer, free flowing but a membrane to keep in fuel. It is on a line to tank and to the inside of LH throttle body, most likely a gray plastic part. There is also a hose for the cap drain that goes down. If you search here you may find pictures of all this, might be in archives from 09-10.
When idling fine, you can maintain idling unplugging any of the plugs. (I didn't find a failure in cylinders).
What do you mean by this ?Are you suggesting that it will idle one one cylinder, dragging the dead one ?
Hi huzo thanks for the message, When the bike is idling in a good manner, its able to still go on if you disconnect one spark plug. It does not matter if it's left or right. I agree with you that sometimes seems like there's one cylinder failing. I am checking at the moment everything related to fuel system. Would you give me any advice for checking related to electrical? Spark Plugs are NGK BR8ESI purchased them by amazon https://www.amazon.es/gp/product/B0000AXR7A/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1ThanksFede
Ok…Next time it misbehaves, take one plug lead off and see if the apparent problem goes away..Try to ascertain if you have one cylinder failing or both..(I think one).If you can find which side, you are on your way.If the bike dies immediately when you remove the (left) cap, then the right cylinder is the failing one.If it does not die, then the left cylinder is the failing one.Personally, I would obtain two timing lights and try to get the bike to fail in the darkness. You should see the hesitancy in the indications of the lights.That of course does not rule out plugs, but you have renewed them.Attaching a timing light would indicate if your issue is fuel or spark.While typing, I wondered if you have a sticking valve.That would link the issue to a hot motor and also provide some context as to why a sharp blip helps to clear it.It REALLY sounds like one pot laying down gently to me….
