It ended up being the tether switch, to much resistance

If you ride where there is any water puddles or mud you should keep your air box.

I decided to use my air box but I had to do some modifications to get the air box boot to go over the carb plus it had shrunk down because it was not as long as it used to be.

I do finally have a few hours on it so at least I can break it in without it being way over to rich. Hopefully I can get to the point soon that I can start dialing the carb in.

I am having the same problem with my stock carb that countryboy is/was having. I bought a carb rebuild kit and have adjusted the float and replaced the needle. (shindy carb kits are of terrible quality). It is still leaking. Carb was thoroughly cleaned and inspected. I even installed a hose and put it to my mouth, blowing air into the carb with the bowl off and would move the float manually up and down...it worked great. However, it still drips when gas is running through it.

Mine acted like it had some mismatched parts for some reason. It was like the float was not designed for the carb I had. I put my 38AS on and it took some modification to get it to fit but it runs much better now.

Part of me wonders if the ethanol in the gas has done something to the carbs, but I don't know.

I thought in order to run a 38 a/s carb you had to remove the airbox or at least the lid....Is that not the case?

The only problem I am having is now I have some major kick back when I try and start it. So much so that my shin is finally healing after 3 weeks and have just pull started it with another quad. I got an OEM used CDI box and it does the same thing so I am going to take the flywheel off to make sure the flywheel didn't spin on the crank. Any other suggestions?

Hey guys and gals,
I bought an 87 250r at the end of Jan. I did a complete tear down with most bearings replaced in the transmission, new hot rod crank, was factory bore and was bored out to the next step. I was having float issues in the carb so I put a new 38AS on and now I have really bad kick back when I try to start it. My shin is still black and blue from just about 2 weeks ago and at this point will not try kick starting it until this issue gets resolved.

The kick back is much worse with the new carb, I could barely tell it with the factory carb. It actually runs pretty good and just needs the carb dialed in. I have only taken it to about half throttle since the rebuild. I was wondering if I would maybe need higher octane gas? I wouldn't think so since the motor is for the most stock specs.

Hey guys,

just an update and question. I got my carb and cable. I was able to put the carb in the intake boot but the boot from the air filter box has shrunk down and shortened. I am thinking about just replacing that boot and air filter. Whats my best option for this? I did run it and it made a world of difference. Its not jetted perfectly but it runs way better and no fuel overflowing.

The only thing I am concerned with is the idle speed is to low. I have the adjustment all the way up, maybe I will need to get it warmed up and make sure the pilot jet and air screw are right to.

its up to you. like stated it will press tight into the stock intake manifold without machining, but the boot on the air box side i do not know, it may need machined on that side, that is if you are running stock boot between airbox and carb. perhaps someone else can chime in.

I think I am going to get their airbox eliminator kit because the boot I have has shrunk down and I could use a new air filter anyways.

Getting ready to place my order, I see at ESR there is a 20 dollar machining option, I am guess that is for machining it so it fits in the intake boot better. Is that a good option or could I do that with some sand paper? Or just skip it altogether.

Looking at getting this carb as well! I have a similar setup. .020" over with a fmf "rev" pipe and vforce 2 reeds. Should we be changing our pipes if we go with the A/S or will the FMF's be fine until more motor work is done?

I am hoping are pipes should be better with a bigger carb, hopefully someone will know.

Thanks, will get an order in now. Hopefully I will have it by the weekend. What should I start with for my main and pilot jet? I just bored the cylinder over .020". The pipe is a FMF gold series Fatty.
