Hi Guys,

OK - question #1: what exact history do you have of the bike? Was it running regularly before you bought it? If it's been sitting idle for years, and if you're a total novice to Laverdas you could be in for a bumpy ride!

Simple things first. Make sure the choke plungers seat fully when 'off' - that means at least a few mm freeplay in the cable at each carburettor. But your mention of carbs off and thorough clean would be a priority if the bike has indeed been sitting around gathering proverbial dust. In fact, treat it as if that's the case and go over the ignition system while you're at it as well.

Hi had it about 4 months done maybe 300/400 miles was fine although never ticked over, did a similar thing about a month ago but cleared after about a mile this time didn’t does start even when hot put requires playing with choke & throttle

As above, check all cables to the carbs and find out what jets are in them, check the floats and level, along with a full carb rebuild. Also check the timing, fuel petcocks and inside of the tank, and what plugs are you using? Remember to turn gas off when not riding it and use ethanol free gas. Do a compression and leak down test and inspect the cylinder walls with a boroscope, all of which will indicate state of the motor.
And change the oil and install a sump cover with magnetic drain bolt from DAM Classic Racing.
