Remove and clean the carb. Reassemble then adjust the pilot screw. This screw is on the bottom outside of the carb centered L & R and forward of the main jet. The screw is nearly recessed in the carb. Turn the screw out 1/2 turn to richen the mixture if the cleaning alone doesn't do the trick. Also, move the clip on the jet needle down one notch for better low speed response. Reset the idle speed as needed.

We understand that your problem is: Me have a Yamaha v-star 1100 custom. He parked it for 1 1/2- 2 years in a storage unit. This whole week we've been working on his bike trying to get it started. We...


When you first turn the key on, you should hear the fuel pump come on and build pressure - it will be a ticking noise. When the pressure is low the pump will run continuously, when the pressure comes up, the ticking will slow down and the pump will stop. The fuel pump is located behind the lowest cover on the left side of the bike - but you can hear it normally with the cover in place. If it's not working, check the fuse - it's in the same area as the pump if I recall correctly.

Also - check your fuel filter - it's under the seat behind the first plastic cover you'll see when you take the seat off.

If none of that works, you might want to drain the tank and pull the petcoc(k) and check the filters on it.

My cbf250 honda will not idle. The engine speed will vary between 1500 rpm to 3000 rpm without any input. Also if the engine is reved whist the bike is on the stand the engine speed will not drop back...


First check to make sure that both of the chokes are not sticking closed after the bike is warmed up. Also check if the throttle grip freeplay is comfortable (2--6 mm) when it sits in idling position. If both are fine then most probably the carburetor may need adjustment & should be left to a trained technician.

My gs500f is back firing through the CARB. the carbs where removed and cleaned they where in good codition.when the suzuki mechanic reassembled the bike and started it the bike dosent want to adjust down...


Lean mixtures burn very slowly, at times slowly enough to continue burning through the power and exhaust stroke, causing a backfire when the intake valve opens, and that flame gets a shot at the new mixture charge.

In normal operation, as the engine slows, the fuel delivery from the main circuit falls off, and the idle circuit is supposed to take over. If the idle circuit flows insufficiently, that becomes a transition to fuel starvation.

You can try pointing an unlit propane torch into the inlet air, and see if you can get closer to an idle while supplying a supplementary fuel source. You will need to do this in a way that gets propane to both carburetor inlets, maybe rigging a Y with vacuum hoses and electrical tape...

This started with work on the carburetors, so the fuel system would be the most suspect. That, and the fact that it will run at higher RPM would seem to rule out fuel delivery.

I was looking around at photos while developing this answer (needed to know whether this was a twin or a 4-cylinder), and one resource said the idle speed should be 1,200. I don't know if that's right, but maybe 1,000 RPM is too slow for this motor to keep it together. (I do doubt that, though.)

When I wrote that last sentence, I started to second guess myself, thinking "What if the fuel shutoff(s) is/are vacuum operated, and as the bike approaches idle there is insufficient vacuum to hold it/them open?" But the I rejected that, because there is even less vacuum at cranking speeds, yet the bike starts.

My 400 ss is reving high when it is warmed up


First check entire length of throttle cable for kinks, crimping or binding. (especially near steering head) Check function of twist grip, it must rotate smoothly and spring back when released. Ensure choke is turned off after initial warm-up. If no change, turn out idle screw fully,(owner's manual refers) start bike and keep throttle at idle speed and screw in idle screw till it engages.

Revs itself


You have an air leak at the manifold. Over-tightening can warp a manifold. The best thing to do here is to get a set of manifold gaskets and replace the old ones. Tighten the bolts evenly in three stages. Seven foot lbs of torque is proper.

1991 CR 500 (reving to high on idle high serges)


take some wd 40 & spray around the carb boot while running to see if the idle drops for a few seconds. sounds like you have an intake side air leak causing a lean condition making the motor rev high.

My idle keeps reving to about 15000rpms


well if the idle is surging(going from 1000 to 1500) you probably have air bubbles in your radiator. i had the same problem. just run your car and then fill it with anitfreeze and let it run without the cap on so all the airbubbles to get out.
and if it just stays at a constant 1500 you can just turn the idle down. a mechanic can do it pretty cheap
