v-star 1100 wont rev up and started poping through carb

[Extrememotors]

help i have tried everything to fix my bike .I have a 2003 v-star 1100 it started poping through the carb then it wont rev up but will idle fine.i have taken the whole motor apart.check the valves for leaks arounds the seets put new plugs in it,new gas, check the valve lash set it to factory .and check the timing compression is good .I don't know about the sensors maybe it could be a sensor.can some one let me know what they think or if they has a similar problem with there v-star.help it has to be something dumb.

I have the service manual. Let me take a look tonight or tomorrow based on your symptoms. Will get back to you.

This sounds like a blocked pilot circuit or possibly incorrect float level. I would suspect the carbs to be the problem. As Bigs has the manuel see what he comes up with as there well may be a sensor somewhere that is playing havoc

Good luck

Sorry I haven't replied sooner. Sick toddler in the house. Ok, first let's start with the obvious. Is the engine light staying "on" or "blinking"? It should come on when you first start the bike (self - diagnosing for any problems), but then go out if all seems ok. If it goes out like normal, we have a few sections in the manual for troubleshooting items. They are: Starting failure/hard starting, Poor idle speed performance, and Poor medium-and-high speed performance. I am guessing by your symptoms, it is the last one. If this is the case, it could be one (or all) of the following: Carburetor (faulty diaphragm, improperly adjusted fuel level, and/or clogged or loose main jet), Air filter (clogged air filter element), Fuel pump (faulty fuel pump). Let me know what you think.

From what Bigs has posted and your earlier post of the symptoms I would suggest a very lean condition when throttle is applied. This is obviously a fuel supply issue. If a fuel pump is fitted I would start there...check the flow and make sure the pump is running consistantly......could even be a loose wire/bad ground connection. Next check the float height...Ask Bigs to find out what the setting should be. If nothing has been recently changed in the carbs and you didn't fit anything else then move onto blocked jets, pilot circuit would be my guess. EasyRider reckons Berrymans Gumout is good so try that or a similar product. Give these points a try and let us know how you go.

Good luck

Measuring and adjusting the fuel level,
Correct reading: fuel level (above the line on the float chamber) = 4 x 5 mm (0.16 x 0.20 in)
Stand the motorcycle on a level surface
Place the motorcycle on a suitable stand to ensure that the bike is standing straight up
Install the fuel level gauge (part YM-01312-A, 90890-01312) to the fuel drain pipe
Loosen the fuel drain screw
Hold the fuel level gauge vertically next to the upper face of the float chamber
Measure the fuel level
Note: fuel level readings should be equal on both sides of the carb assembly
To adjust if out of tolerance:
Remove carb assembly
Check needle valve seat and needle valve
If either is worn, replace them as a set
If both are fine, adjust the float level by slightly bending the float tang
Install the carb assembly
Measure again
Repeat adjustment steps until fuel level is within spec
