Good day. I am interested in casting bigger barrels cylinders for a yamaha banshee. I am interestes in 300cc ktm barrel with the powervalve housing. The banshee is a twin cylinder so this would make it a 600cc two stroke. If you can make similar barrels to fit the bashee casing? If you dont do this Type of manufacturing can you please provide me details of a company that manufacture such items. I will highly appreciate it!
