Welcome to the world of big, single cylinder crossers.

You want to try it with a 500cc 4-stroke.

Its easy this one ! try the following in this order
The fuel is evaporating from the carb, make up some sort of heat shield that dissipates heat away from the float bowel, ie small bit of thick rubber or plastic .

Change the plug, make sure it is the correct one as per manufacturer reccomendations.

Still now working ? take off carb and check floats (correct height is eesential) . Clean out jets, Clean Air filter, use fresh new fuel and a good oil.

Check pick- up connection , may be loose or damaged .

Thumbs Up

what year is the bike ?
