My 2003 Speedmaster has been sitting for awhile and would not start. I replaced the gas, main and pilot jets but I am not getting gas into the float bowls. What should I do?

    I put an inline fuel filter in after the petcock since the filters on the petcock themselves are dried up. I am getting gas out of the petcock ok but it is not traveling down to the carburator float bowls. Can something be clogging it up so that the gas is not going into the float bowl? I pulled the floatbowl cover off and I could not see much other than the float itself moves up and down ok.

Turn on the fuel to Reserve or Prime position, does fuel flow to the carb? remove the line to verify this, If it does reconnect the gas line to the carb and see if it starts. Let me know.

You may have a clogged tank vent. Open the gas cap, then try to start the bike again. If your bike still does not start then replace your fuel filter. If the fuel filter is clogged, the sentiment will settle on the bottom and prevent your bike from starting.

Xl250 r 1987 where is the pilot jet located

Remove carburettor bowl and the pilot jet is just forward of the main jet and emulsion tube. If pilot jet is blocked either carb clean or strand of electrical wire will clear it then blow out with compressed air. Fuel mixture screw is just forward of float bowl. Start at 1& half turns out from seated.

Only runs with full choke, I bought the bike last week and the float needle was stuck and I think it had bad gas. so I changed the gas, cleaned the carb, reset the float needle. I also set the main slide...

Hi mate reverse the needle clip position back to factory setting this issue is pilot circuit for sure - If you have cleaned carbi you need to replace or clean the pilot jet and compress air clean the hole where the pilot jet came out of to clear the circuit. Running only with choke on is classic symptom of block pilot circuit...
Also check you fuel air mix screw this may have been altered trying to correct this issue it should be 1.5 - 2.5 turns out from fully closed..
all the change of needle position clip is doing is allowing your bike to run off the main jet (not good)
and reason for running with choke on is it is changes air fuel mix with choke on compensating for lack of fuel from the pilot jet blockage

I have a 98 kx 250 cleaned carb has good spark and its not getting gas wont start?????

Please check your jetting ( main & pilot ). Are they work. Check also your floating valve for stuck. A stuck floating valve will not allow the fuel flow.

My bike has been sitting for a year and I put fresh fuel and oil in it but I can't get it to start without starting fluid, I'm trying to check the carb float for gunk or something but I can't figure out...

the fuel inthe carby will have gone off and blocked the pilot jet. you will need to remove carb and clean out. to do this you need to remove seat,tank, raise the rear sub frame so you can get out carb. once carb removed you will need to clean out needle valve, main & pilot jet, may even need to put fine wire through pilot jet to clear blocked jet. reassemble and bike should run,I do a 4 a week with this problem.

I have a 1990 suzuki rm 125 starts first kick, but boggs alot, every once and awhile power band kicks in and it runs good. I checked spark good and blue, checked reed valve in good shape. pulled head...

I'd start by thoroughly cleaning out your carb.,...check/replace the main jet with a leaner, [higher #], jet...change/clean pilot jet also,..spray carb cleaner in all holes and blow out w/compressed air. Re-check your float height and/or any damage to the float pin+tangs etc. Maybe try a 50:1 gas:oil mixture. Perform a leakdown test,..air will cause boggs as well. *[p.s.; does bike blow oil out exhaust?].

Almost like getting no gas

How long has the bike been sitting?? From what your saying i would start with cleaning the carb. as gas sits it will gum up and block you jets. the carb in bike and most bike have 2 jets pilot and main the pilot the is idle jet and is hooked into the air/fuel screw. it is the smallest of the jets that pick up gas. when you have your choke on it lets the gas " bypass the pilot and feeds gas to the motor when you turn it off it is all up to the pilot jet and if it is gummed up your bike will not idle.
Take a look at the microfishe if it looks to much for you i would take it to you local shop

I have a 2001 yamaha v star 1100 starting, but not firing it has been sitting since last summer i have replaced the plugs, but it still has teh same gas in it. Could the gas sitting that long with no...

The problem is most likely the pilot jets in the carbs are clogged. As gasoline sits, it changes its form to that of a varnish or jellied state. This can take as little as 3 months or less. There are a collection of jets in the carbs designed to effect specific parts of the throttle input, but your main focus is the pilot jets. These are the smallest ones and are easiest to clog.
When you disassemble the float bowl area (bottoms) of the carbs, remove ALL the jets and soak them in carb cleaner. Using compressed air, blow through all of the passages in the carb body. Remove the jets from the carb cleaner and blow compressed air through the jet orifices. Carefully reassemble the carbs and reinstall them on the bike and you should be all set. :)
If you get stuck give me a call. I'd be glad to help!

Misfire and backfire at low rpm, runs rough at low rpm

You did not say whether or not this was a carburater engine but from the sound of it one of your jets may be sticking, a good cleaning of the jets will most likely fix the problem, the likely cause is a small build up or piece of debris on the jet.
