Banshee wont cold start

[drave199]

i have a 99 banshee. some mods (exhaust, cool head). i recently had the carbs rebuilt and had the same issues like not idling and no cold start. once it is warm it starts just fine and runs like a beast. i took it to a shop and they said the carbs weren't synced. they synced them and made sure i was jetted right for where i live. now it runs even better and even idles, but still wont cold start.

 

BTW, compression is good 

 

any help or advice?

Do you use the choke to get it started?

[Jereme6655]

what jets are in it?  You asked the "shop" what they put in it correct?  I bet either you have an air leak, a too small of a pilot jet, or your not telling us that it got extremely cold since you had your bike taken to a shop and that is the reason.

[drave199]

yes i have tried various different ways to attempt to start it.

 

to be honest i dont know for sure what jets are in it. what i am thinking and have heard is maybe my pilot jets are getting flooded in between rides because it usually some time between each ride. i unfortunately dont ride every weekend.

Pilot jets don't flood. Id bet they are too small. Quit taking it to the shop and get your hands dirty and start messing with it yourself.

what do you consider as "good" compression, mines a pig to start but i know its due for a freshen up

sounds almost like your rings are sticking.. time for a top end

I would assume your float bowls are on the wrong carb. To operate the choke it must have the float bowl with a cross drilled choke tube hole.

Look at the front if each if your float bowls. One should have a small brass ball pressed in the front if it. This bowl needs to be on your left side or choke side carb.you can look while carbs are on bike.

If this is correct your out of luck. Lol

Well I had the same issue. Took about good 50-60 kicks to start when cold. I checked the compression and it was good so I cleaned the pilots jets with a piece of wire brush and cleaned the carbs with carby cleaner then it started within 2-3 kicks every time.

it gets below zero where im at you have to watch what mixing oil your useing im a huge fan of castor 927 but i can not use it in the winter time because ive been told that below a certain temp. the shit actually will seperate from the gas so that might be something to look into if all else is still failing

[rocketracing]

if the carbs are clean and everything is where it is supposed to be, and jet sizing is right, you might need to adjust your  air/fuel mixture screws. I would start at about a turn and a half.

^^^ is very true.

 

How old are your spark plugs?

 

Do you know how many turns out you have on your airscrews?

Tired/chipped reeds will make a 'hard starter' too.... Something to consider as well.

It doesn't have to get cold for the 927 to separate. It happened to me after my bike sat a couple of months. You can tell if this is the case by opening the bowl drain and see what comes out.
