Question about 1987 Suzuki RG 500

1 Answer

Starting problem my bike has difficulty starting in the morning. I tried with and without the choke, with and without throttle. I would try to start in the morning but engine just keeps cranking only. I would wait an hour or so and try again, and it would start. Some mornings it seems like it would start when I push the start but only for a second and then continue . I check the plugs and is dry. Float bowl has gas. Any help is greatly appreciated.

I use to have the same bike as yours 4 months ago. It is a good bike and very reliable. When using choke, do not use the throttle, just cranking it and it will start. Another way is spray couple shots of "Starting fluid" in the air box.

Turns over but dose not start, spark plug sparking ok


Check you have petrol if the bike has not been run for sometime replace the fuel. Petrol ages and causes all manner of problems.
Are you trying to start the bike but it has gone onto reserve, move the fuel tap to the reserve position then try to start it. If the above fails, then try these:-
Is the spark plug wet when removed. If dry it sounds like the petrol is not getting through. Try opening the filler cap and leave it open, make sure the kill switch is in the run position. Try starting with the throttle full open. Does the bike have a manual choke try to start with the throttle shut, choke off, then full on, then while continuing to turn over move the choke lever in stages from fully on to fully off. I find on my Yam TW125 (winter and bad weather hack) that if I have not used it for a while sharp twist the throttle a couple of times no more than a third of a turn. Hope this helps.

How do you cold start?


If everything is in good working order many newcomers to their bikes make a mistake when starting them cold they tend to open the throttle when the motor needs a richer mixture to run and start, now here is the secret lol full choke and do not touch the throttle do not open it when cold cranking the bike,once it starts then as it warms up ease off the choke then your good to go.

Hard to start how do the choke work


The choke is automatic. If the bike is having that much difficulty starting you need to have the bike serviced and the carburetor gone thru.

1996 Kawasaki VN 800 Vulcan Classic hard to start when cold


Hi, Pete before you start it in the morning, pull the spark plugs and sniff them. Do they smell like gasoline? Are they wet? If so, you may have fuel leaking past the needle and seat in the carburetor and flooding the cylinders.
Use a voltmeter on the battery an hour after you shut the bike off. It should be at least 12.6 volts. Check it again in the morning. It should still be 12.6 volts or more. If not, something could be drawing current when the key is off.
If it's a carbureted bike and the ambient temperature is warm, you may be over-using your choke/enrichner. Try cranking it with the choke turned off first and then try half-choke, and then full choke. If you start with too much choke it will flood. After it starts, shut the choke off after 15 - 30 seconds and then use the throttle to keep the bike running until it warms up. Over-using the choke will soot up your spark plugs.
A fresh set of properly gapped spark plugs can make a lot of difference in how easily a bike starts.
Engines need a richer fuel mixture when they're cold. An intake leak can also cause hard starting because it leans out the air/fuel mixture.
After you get the bike started, spray some WD-40 or carb cleaner around the carburetor intake manifold seals. If the RPMs change, you have an intake leak.

this is not a complint. Only cold starting problem. Either you warm up the engine by closing the choke lever half and opening the throttle slightly or try with closing the piolet screw half turns, in this case you get less milage for your bike.

My 2003 suzuki gsxr won't star has been sitting in the garage for three months without starting it cranks over pretty good, did I choke the engine with too much gas trying to start it?


Hi from Spain,

no way to choke this fuel injected bike in theory....but by my experience try to start the bike with fully open throttle several times, take care do not flat the battery, if the bike has not much fuel do not try with the bike on the side stand so the fuel cannot reach the fuel pump inlet.

BR,

Emilio.

Sounds like the battery may be weak, recharge and test, maybe replace. As far as starting, most Hondas will not start if you open the throttle any at all. Shadows being liquid cooled are generally cold natured, but you should be able to ride away with the choke on in 1 or 2 minutes, you might have to ride as far as 4 or 5 miles at highway speed before you can take the choke fully off. If it is taking longer than these times, you will need to remove and clean the carbs. the low speed jets may be partially blocked up.

2008 KTM 530 EXC is a bugger to start.


While it's generally considered a cardinal sin to touch the trottle on a thumper while starting. I found my pumpkin liked to have a quick squirt (little blip of the throttle) before trying 1st. Got luck I discovered this after many hours of head scratching.
