Backfiring is typical for 'lean' conditions and stuck inlet valves.
check also the spark plug condition, replace them if any doubt on their age exists.
Check compression to discover open valves.
Clean out the carburettors.

Can I get fuel and vacuum line diagram for a 1989 Suzuki katana 750f? Thank you email is danlco19891@gmail.com


Im pretty sure the two bigger pipes are the fuel pipes and they go from either side of the fuel tap to the carbs one is on and one is reserve.then the smaller pipe goes on the fuel tap to the smallest outlet and then goes to the top of the 3rd carb diaphragm cap.if it's the same as what we call a gsx750f in the UK.

Don't use cold start.it will not solve your problem.Try running it with out the air cleaners ,it may be that you have an air intake problem and not getting the right Air / fuel mixture .
