Question about 1989 Suzuki DR 750 S

1 Answer

Starting and general running

Engine does not start with starter motor. on pressing the start button the motor will swing over once and then rotate once very slowly, and by keeping the button in continues to give one quick rotation and one slow rotation. motorcycle was towed and eventually started, but would not idle and then cut out. what should i look for ?
also the previous owner removed the petrol tank, and did not know how to put it back correctly. is it possible to send a diagramme of the fuel system from tank to carbs.

regards
Doug

The fuel system should just run directly to the carbs through filters. The starter though, sounds as though the cannot turn the engine over. And if it was push started and didn't run.....then I would guess there are internal engine issues. That is just a worst case prognosis. There are a few options otherwise. Try a new starter. Make sure the battery is fully charged. If that bike uses a coil system then the battery has to have a charge in order for the coils to keep the bike running.

Power getting to stater but wont crank over


No mention of model...so these are general comments.

First, when you say there is power to the starter, do you mean the actual starter or the starter relay (or starter solenoid). On most Yamahas there is power to the starter solenoid from the battery at all times.....power leaves the relay to the actual starter motor only when the key is on, the interlocks are satisfied and the starter button is pushed.

So if you actually are getting power at the starter motor and no rotation, and the battery is fully charged you have either a starter motor issue or an internal engine/clutch problem. Is the bike physically in neutral ...rear wheel spins? Remove spark plugs and attempt to rotate engine with kick starter if equipped, or access rotor bolt and rotate with socket...if it rotates fine...remove starter motor and inspect,

If the starter relay is not sending power to starter motor....check Kill switch is in ENGINE RUN position, bike is in neutral, and indicated on dash, and retry. If you have no neutral light showing, but it is in neutral, you need to flip the sidestand up...pull in the clutch and retryt....as there is a sidestand switch and a clutch switch that are part of in gear starting interlocks.
No neutral light indication requires testing of the neutral switch aand wiring but tryt to get the bike running first.

Hi I have a 2005 ultra with 58 k miles, when started to ride or warm it up, it starts fine then at no given time you hear a chatter noise as if the starter is engaging and then disengaging. Could this be ?...


If you'll look just behind the rear cylinder, there is a black thing with a large cable running to it. This is the starter on your bike.

I could be your starter hanging up. When you press the start button, the jackshaft is pushed out by the solenoid part of your starter and it engages the ring gear on your outer clutch drum. The starter motor starts up and turns your engine. Once the engine fires, the jackshaft is now turned faster than the starter motor can turn it and the starter clutch allows it to "free wheel" until you let off on the start button. Once you let off on the start button, the solenoid demagnetizes and pulls the jackshaft out of engagement with the ring gear.

If you think the starter is hanging up, you need to take it to a qualified mechanic and have it checked. Since you don't know where the starter is, I would be hesitant to tell you how to try to repair the starter. Have it checked out before the starter clutch locks up and the starter is destroyed and cause damage in other areas as well.

My BMW R1100RT is difficult to start. Must use full choke, give full throttle once and then hit the start button. It then starts just when I let go of the start button. Often it refuses to start and then...


The choke actually just opens the throttle bodies a little (the bike is fuel injected). Try using putting on the 'choke', then pressing the start button, but dont touch the throttle. Does it start ok? Also, when started, if you use the 'choke' does it increase the engine speed? If it does not, then you need to set it up correctly.
Let us know how you get on.

Engine wont start...


since have change new battery, will the motor turn over? if the engine turn over or crank, check if you have sparks, by pulling the plug out and ground it to the metal to the bike and turn the motor over and see if you getting spark, double check if you are getting fuel, two items to make the engine run, sparks and fuel. if the stater dont make any sound when you press the start button it may be faulty serenoid to the starter, check starter and starter switch. you can get a light tester and test positve and negative contact to your serenoid/starter by hold or pressing start button to see if you get power to the starter. hope that help some

Kawasaki zzr600e wont start


If you are not getting the starter to wind after pressing the start switch check these probs.Have you checked the fuses for the ignition switch? Check all fuses. Track the wiring from switch and check all plugs and connections.  Turn ignition on and try clutch starting the bike to see if the motor will run once it is cranked over. If you need to bump it, make sure all your connections and wiring are all making good contact. You must conduct a process of ilimination in order to rectify the fault. good luck.

Honda Deauville will not start.


Hi and welcome to FixYa,

The click is significant. It indicates that the starting relay is engaging but for some reason, the starter motor is not cranking. This could either be a faulty starter relay (particularly the contacts) or a faulty starter motor (specifically, the carbon brushes). To determine which:
  • with the side covers off, expose the starter relay particularly the 2 large terminals;
  • have somebody start the bike normally using the key and button start switch;
  • determine if indeed the clicking is coming from the starter relay;
  • while the start button is still pressed, jump the 2 big terminals;
  • if the engine cranks, then the internal contacts of the starter relay are corroded or burned;
  • if the engine will not crank, then the starter motor is faulty or it can not turn the engine..
A few additional ideas:
  • externally charge the battery;
  • drain the tank and carbs of stale fuel;
  • refill with fresh fuel;
  • remove the plugs, center stand the bike, engage 1st gear, rotate rear wheel to exercise engine.
  • Good luck and thank you for using FixYa.

Hi and welcome to FixYa,

Initially, determine if there is a clicking sound when the START button is pressed. The click is significant. If there is, this indicates that the starting relay is engaging but for some reason, the starter motor is not cranking. This could either indicate a faulty starter relay (particularly the contacts) or a faulty starter motor (specifically, the carbon brushes). To determine which:

  • if the engine will not crank, then the starter motor is faulty.

Starter problem


most of the times recently the auto start does not work . I contaced the service man he is now recharging the battery . Did the wrong usage of auto start ( pressing the button and accelerating at the same time ) cause the problem only later I knew the pressing of button only suffices the start ,Generally speaking, revving the engine at start-up isn't good for the motor. It's best to let it warm up a bit before cracking the throttle. It sounds as though the battery was just weak. The only thing that will result from pressing the starter button and twisting the throttle at the same time is additional wear on your engine (and maybe the starter motor too).,,,
