i have enough parts to start an exchange or borrow program
for those with mis-matched numbers when a motor needs a rebuild, for a dollar figure and your old motor, a freshly rebuilt motor can delivered and the bike is off the road for a day or 2 instead of several weeks/months while you rebuild it yourself,
for those that have matching numbers the motor could be loaned whilst you get the original rebuilt, then returned, meaning your still riding the bike and not looking at it in a shed in pieces
the same can be done for carbs of different models, dollars and your set for exchange for a plug and play set,
would it be worth the effort before the dollars are spent or would every one like to do their own work
