Hard Starting even when it is warm out

[yamban88]

I just had my top end redone and I can't seem to get it started. It will start one day and the next day I go out to do some more adjusting on it and it won't start. I thought that it was my fuel mixture cause I mixed it a little heavy to break everything back in. So I drained that and remixed at 24-1. It seemed to help up until today.

 

I went out to start it and nothing. The compression is good the carbs are clean the plugs look normal and I have good spark. If I spray a little starting fluid in it it will start and I have no problems the rest of the day. What could my problem be?

did you put the hose back on that conects to both carbs.sounds like an air leak possibly.check both carb sync windows make sure the plastic piece didnt fall out rare but it did happen to me.undo fuel hoses at carbs turn on fuel real quick make sure yuor getting fuel to them ok.probly just a fuel delivery problem.you will prolly find if you remove your plugs and pour a little fuel in each cylinder it will fire as well

Well tonight I checked everything over again and I am getting fuel into everything. It will start for a few seconds and then as soon as I give it a little gas to help it idle it floods out, it also popped a couple of times out of the silencers when gas was applied.

 

I rechecked my carbs to see if the slides were sticking or and they are not. Nothing is plugged either. Fuel runs out everywhere, all the clamps are tight between airbox carbs and reed valve. Carbs are in sync.

 

It ran the other day but had a lot of blue smoke but I figured it was my jetting. I had stock exhaust on. Today is when I had all my starting problems I put fmf pipes and silencers on and rejetted it and again it starts for a few seconds and then quits. Help!!!! I have already stuck a lot of money in it and don't want to take it to a shop to have them figure it out unless I have to.

first, i think you mix your oil too rich, that might be why it starts and then dies, but does it start with the choke on? and if its backfiring out of the pipe you need to look at timing, plugs, coil cause it is probably misfiring

It was starting easily with the choke on before I put the fmf's on. Usually first or second kick. I have tried different plugs and that doesn't help either. I knew the fuel was still a rich but it should still be able to start shouldn't it? This is the first banshee I am trying to fix myself instead of taking it in, but am getting extremely pissed at it. Would I be better off draining all my fuel and mixing it lighter to see if that works? I am stumped everything tests out fine everything is clean. Please Help!!
