MZ/MuZ Riders

so i let my mz baghira run low on fuel and whilst on reserve i put 5 litres in it ,only a small amount because i'm mothballing it for the winter, anyways , i switched peticok over to ON a everything was fine , then down the road a mile she spluttered on then engine failed , pulled over and put her back on reserve and away she went , noticed now at low revs she's boggy a bit like she's running out of petrol again??I think i remember i've had this issue before with it not working well on reserve,,any ideas,befor i strip her off. whats the total amount for reserve fuel?.Am i right in thinking if fuel is being starved from the peticok the it can equate to a low float level in the carb

had a bunch of problems with my rt125 on reserve found that there was a bunch of crud
in the bottom of tank from the small amounts of E gas ..i used
i run pure gas most of the time

some tanks are shaped funny and have a spot where old fuel gets trapped

i usually remove and dump the tank at least once a year and park it with pure-gas

and start it often in cold weather

we have some nice days in the middle of winter here so i like to take it for a blast some times
