dry plugs is not enough fuel and running too lean check jet blockage , float levels and fuel flow problems

the sades are different sizes, should only go on one way?

it maybe sucking air around intake boots

No. That box fits the VV engine onwards - with the red cam cover. This has a single plug - you need the twin plug Cdi box

I suggest you stick with the stock tire size. If you don't, the speedometer will not read correctly. With a smaller tire if the speedo says 65 you will really be doing 55 or so. The actual mileage driven will be off as well. The lower profile tires also do not cushion the rim as well. The spokes are more likely to get out of whack. It is also harder on the brakes since the brake disk is spinning faster to go the same distance as a stock tire would be turning.

Everything you want to know about the bike can be found in the VIN number (letter). In this case pay attention to the 10th digit (reading left to right). This may help too: http://www.suzukicycles.org/Bandit-series/GSF400-Bandit.shtml Good hunting....

breakers yard or suzuki dealer !

The positive lead in the one going into the coil . The negative is the one grounded or shown bare on the outside of the coil.

Maybe some water in an electrical plug. Remove the tank and dry it all out with compressed air or WD40. Work around the coils and other wiring. Also where the wires come out of the engine case.

blocked carbs, get a good fuel system cleaner, if you in USA get Berrymans B12, double the dose and mix in tank. run til hot then leave to stand overnight. also if you can remove the air cleaner to get to carb intake, get spray carb cleaner an chuck a load in there. also check to see if you have a fuel filter inline

dear,

not to worry for the same .

the new chain assembly often gets loose for the first 150 miles and needs to be adjusted.

get it adjusted and look for the lock nut and the clip at the end of the rear fork .
then the problem might not happen

thanx

Normally, a knocking sound in a specific gear set indicates a broken gear tooth. When replacing a broken gear, replace the gear(s) it engages with as well. If you don't replace them you will have the pleasure of doing the repair job all over again when the weakened tooth on the existing gear(s) breaks off. Remember, whatever caused the problem in the first place put pressure on both the broken tooth and the gear it was engaged to at the time. Most likely is a tooth on a slider gear.

i think the fuel filter inside the tank is dirty, or the fuel on the float bowl of the carb is low that when you give gas the fuel in the bowl runs out.

ur bike is 20yrs-may be time for a rebuild--crankcase gasket cud be leakin or bolts loosin their torque-get a tech manual to see if ur comfortable in this maintenance

sounds like you have a stuck open float in one of your carbs,try cleaning the float needle and its seat,inspect needle while disassembled if the needle has a ring on its tip,replace it and seat with a new set

Ure side stand switch is jammed or not working properly depress pin and try again or disconnect or bridge

Once you remove the gas tank, it will be very obvious. Cable easily comes out of the thumb mechanism easily when you take it apart.
