Hi Guys. Wonder if you can help me out? Bought an XV750, as mentioned in previous posts, and it conked out on the way home after 30 miles. Green flag obliged and I cleaned out the concrete-like blockages from all of the jets, bowl etc and managed to run it intermittently sometimes on one cylinder. Forked out £160 to have the carbs rejetted, cleaned etc and it ran fine for a few miles then started chugging. Checked the plugs and they were choked up with carbon preventing sparking. Cleaned and started resetting pilot jets and running in between until I had them turned out 3 and a half turns. Still fouling! Did that paper test thingy on the remote Mixture Control Valve. No vacuum throughout the engine rev range from 1000 to 5000. Sourced a used one and tested. No vacuum still but sucks paper in when revs let off!! What's it all about???. I fitted 2 new standard Plugs as per Haynes and the air filter is clean. Read on a forum somewhere about removing the MCV and blocking off the two vacuum tubes. Is this an option or a total fantasy?? Apart from stopping every few miles it is obviously using a lot of fuel so it's no laughing matter!! And, to be perfectly honest I look a right twat stood at the side of the road tinkering or sweating like a Sumo Wrestler in a Sauna as I push it home in my leathers and Damart Thermawear!! I have been trying to do this alone but I am completely flummoxed and would appreciate any help you Heroes can offer. Regards

Hi Guys, I just bought an XV750 1982 so I joined your club to find out more about it and to see if I can pick your collective brain. It has, what I gather from extensive reading, are usual problems associated with this model, about which more later, after I have perused your forum for FAQ's Regards
