    either clean the plugs with carb cleaner or replace them ! plug caps could also have too much resistance , check them all also with multi metre !

SOURCE: drz 400 sm starts but i cant give it any gas or it dies

Can you slowly increase the revs? It sounds like an accelerator pump or debris in the carb.

SOURCE: i need to install a voltage regulator on my sportster.

IT IS YOUR IGNITION MODULE. Drill out the rivits and remove the plate that shows the 5 speed. Then pull out the inner plate and there is the module. Its like 200 bucks but worth it. Then under the bike, there is a plug. Un plug it and cut the cable. Save the pin out on the plug so you can match the new one up. Then reverse the removal for the install and turn the ignition on. You should see a red blinking light on the new module. It will start and you will see a solid red LED. Button it up however you want, just make sure its tight and right.;

My fzr 400 will start when it's cool engine and when it's hot will not start ineed help

If your driving and it gets warmed up and shuts off and wont restart it may be a float problem in your carbs. The float needle will get corroded and let gas constantly flow while the bike is on and while you try to start it after it cools you burn the extra gas it only starts cold. Ive had personal experience here. New float needles.

Motorcycle dies after 5min

If it's dying that quick because the battery went dead, it might be a charging problem.

Get a MultiMeter:

Make sure the battery is charged, and start the bike.

Put the multimeter leads across the battery terminals (red to +, black to -)
You should be getting 13-14 volts, with the voltage increasing as you rev the motor.

If not, either an alternator or voltage regulator problem.

IF the battery is going flat in that time WITHOUT the motor running, you have a "parasitic" drain somewhere, that is draining the battery when it's off.

My fzr 600 1989 wont start off the start botton nothing at all is happeanig black really not clickin and i have put new battery on and solenoid

Hello mike, first check all the fuses, make sure none are blown. Check the kill & safety switches. Clean the contacts on the starter button. These are the basics.
I hope this helps.

I have a yamaha 1987 fz 750 ran great put up for winter but now wont start drain gas and cards put new gas in sill wont start backfire 1 or two times got spark

If old gas sat in the carb.s for more than a month it starts to dry up. As it drys up it leaves behind a varnish like film that stops up some very small ports and pin holes inside a motorcycle carburetor. It is also very hard to get out. You can try this before you pull the carb.s for a full cleaning. Use a product called Seafoam, get as much gas out of the carb.s as you can. use a turkey baster and force the seafoam into your carb.s fuel line that you took loose from the fuel tank. Let that set for days 1 or 2. then hook up the fuel tank with a mix of good gas and seafoam, (not a lot but enough to start it up. Move the cycle outside as the seafoam will make a lot of smoke if it does start up. If that does not clear up the problem you may have to pull the carb.s and remove the blows to clean the inside. If you have to do that do not DO NOT MESS with any adjustment screws, DO NoT MeSs with any screws. Just take the carb. bowls off keep each one separate and number them so they do not get mixed up. do not mix up any internal parts. It is best to work on one at the time so nothing goes wrong. Work on a large sheet so if you drop a small part you can find it, you do not want to be missing some tiny spring or screw. Hope this Helps.

I have a 91 fzr 600 recently did oil change, spark plugs,didnt ride bike for 2 days then went to ride it today and wont start, thought it was the battery so i jumped it and it started but started running...

you will need to try a new battery, unfortunatly sometimes jumping of a larger battery can spike the regulator, so when the new battery is fitted put a mulimeter across the battery, should read just over 12v engine stopped and rise to 13.5-14v with the engine running.

Bike wont start

You have to check the starter motor,prolly the brushes are gone . Also check the connections from battery to the solenoid and from the solenoid to the starter.

Good Luck.

Too much oil in engine

The cutting out is just a coincidence. Go with the correct amount of oil. The piston is splash lubricated. Too much oil kills the splash and the cylinder gets poor lubrication. If your model has a carb, ( as opposed to fuel injection ), then clean the carb and air filter then put in a new stock NGK spark plug. This should take care of the problem.

Please rate this solution. Thanks niknak!
