Hello all...Just purchased a 1987 Beluga Cv80T. I has 89 original one owner miles. Has been sitting for years, never was used by original owner much after his wife tipped it over! After getting the inside of the tank completely cleaned of rust, I am having a few issues. 1- fellow I bought it from had a small 12 volt battery installed that worked fine but I have removed it....I have a 6V ordered...Since everything works I assume no damage from 12 volt? 2- I have cleaned bowl, checked diaphrams, cleaned lines in carb that go to top of cylinder.. cleaned / checked jets.....bike starts fine but surges at idle. Not sure of weird vacuum operated petcock but was wondering if I could bypass it and run straight from tank to carb? I have noticed that the idle screw is turn in very far to keep a idle.....Also, original air filter was junk so I have a sheet of UNI foam ordered and will cut my own.....Any thought from you guys is really appreciated as I bought this for my wife!
Thanks, Todd

That's a sweet scoot. The crappy idle is probably carb/choke related. The vacuum actuated petcock is a pain, and should be replaced with a manually controllable one. A straight line to the carb won't work, it's too powerful of a stream and the weird old Mikuni carb isn't adjustable in that regard.....

If you want ease, replace the carb with a more supported Mikuni like a roundslide 15-19mm. I use Dellorto carbs, they work great too. OKO carbs are cheaper and copies of both. They all have manual chokes too, very handy!

You will make it work fine if you go one step at a time, don't change too many things at once until you get a clear understanding of how it all works.

Ask more questions as needed.
