I’m Josh from the Cornwall branch of the motoguzzi club (currently living in London) this is my first post on the guzzi forum and sorry its such a monster …
I would like to ask for advice about my recently restored V50 which seems to be fairly ill.
Ill give as much information as i can about the issues and the lead up their occurrence as i can. I should also mention that i am still fairly inexperienced as a both a rider and DIY mechanic but am looking forward to improving in both areas in the near future.
My dad and I restored his old V50 MKII this summer and had it running pretty well. It had a few trips to the garage to totally overhaul the charging system and check the electrics + get and MOT and have a carburation tuneup. We did a full carburetor overhaul using the wonderful guides on thisoldtractor (am i allowed to do that) and gave it our best with the electrics and the cosmetics.
I decided the day after it was all legal to take it from Cornwall to London to live with me at university. This was its first real ride out however since being restored. It had only done short 5-10 mile stints leading up to that trip. A few days after i had arrived in London i started it up and started to ride of, it stalled a few times and i put it down to needing to warm up/bad riding and persisted on my journey. However after 500 meters i realized it wasn’t getting any better, maybe even worse i couldn’t get over 20 mph and this engine thumping laboring was occurring along with jumping uneven revs. it finally conked out when i was trying to escape a bus up a hill at about 10mph coming back home so i pushed the rest of the way.
So summerize - The current problem is as follows: the bike starts and idles OK (perhaps less perfect than it did a few weeks ago right after the restoration) however when you put it under any load it has no power, the revs jump around large amounts at the same acceleration, and you can feel some kind of ‘jumping’ pulsing trauma coming from the bike. It moves but is impossible to ride and when i have been fiddling and ride it around the car park nearby it feels very much like i should be so i push it home …
I have taken of an checked a carburetor which had a minor leak from the inlet and filter area (which seems to still be occurring)
Taken of the plugs and tried to clean them up a bit, they where and are still very black
Checked what electrics i can, pushed in the fuses and checked earthing points that i can find.
Ive asked around wherever i can, a couple of people think it could be carburation, others fuel supply and others electrics and ignition.
I am hoping to ideally solve this problem myself but i have got RAC rescue as an option to get the bike to a garage. But even then i would like to be present when the works are happening or informed of what was wrong so that i get a better understanding of the bike.
If anyone can offer advice, or recommend a good mechanic in the north London area (in N88AE crouch end) i would really appreciate it.
If you made it this far down the post thankyou and i look forward to any responses !
