Starts hard but runs great?

[maxtrax]

I bought a Banshee earlier this summer because the carbs were all screwed up. When I first got it it started first kick every time but ran like crap. Here is what I did to it.

 

Put the proper slides in the R/L carbs

Installed proper air jets as they were different R/L

Jetted from 220 to 300 as I put on 6"UNI filters and it had FMF Fatty Golds and PowerCore2 silencers.

I run 93 octane and Maxima Castor 927 oil in it.

 

It does bobble a little at about 1/4 throttle but idles good and runs great wide open. The problem that I am running into is that it doesn't start good after sitting for more than a couple hours (starts fine when warm). It pisses me off when I want to ride and it wont friggin start :mad: I am going to do a plug chop but can't find the link and haven't had time.

 

Thanks

Andrew

try a bgger pilot possibly a 27.5 or 30 i had to put a 30 in my banshee whe i had the procircuits on it it was a pain to start till iput that in

Seems to be a bit of the norm around here cause I have seen several posts about it. I did everything that was suggested and to no avail. I would just put alittle fuel down the jug and it would start right up.

What he said.

[SCEADU]

Iwas running a 30 pilot in mine and it still did it. I tried a 25,27.5 and then the 30 the problem never changed.

weird thing i noticed is that there is no main in the carb now? will that cause no idle and hard starts?

[maxtrax]

I will try increasing the jet to a 30. I think that when I got it that one of the carbs had a 30 in it but the other was a 25. I put them both at 25 to make them even but am thinking that may have an effect.

 

Does anyone do a cool at the end of their run? I am wondering if because I usually do a little lighter lap before parking that that may have an effect?

 

Thanks for the advice.

do you have your air screws adjusted at all?

i'd set them about 1.5 turns out from lightly seated

and go from there.

[maxtrax]

That is where they are set at. I have tried a little out and a little in from there too. I also found the other day that one of the screws was missing the spring from underneath it and installed one. A while back I had 310 mains in it and thought that it was too rich (which it was) and that 300 mains would fix it. That fixed the richness problem but not the starting problem.

your starting problem is in the pilot circuit.

have you tried turning the air screws in almost fully seated?

[maxtrax]

No I have not. I will try that tommorrow.
