Yes it has spark but bike is flooding. why?

I lot depends on the bike model and whether it is normally aspirated or fuel injected. Assuming no problems with a carburetor, opening the throttle too wide trying to start the bike. Choke on and start with a closed throttle opening and increasing to no more than a quarter turn.

Could also be worn out, badly gapped or sooty plugs. Wet plugs and sooty plugs (carbon is electrically conductive) don't let the spark jump as well especially under compression. Remove the plugs and heat them up with a gas torch or a ring on your stove. Put them back in hot.

My Susiki dies sometimes when I make a stop or slow dow suddently. Whats the problem?

I would start with the easy less expensive stuff first.
Check/Replace your spark plugs. Carbon fouled, sooty plugs don't like to idle.
Clean/Change your airfilter. Dirty air filters choke the motor. choked motors either stall or rev high.
Carburetor idle screw needs set.
that is adjusted after the bike is warmed up to operating temperature, then set idle.
If that doesn't have you cleared up then you'll need to have your carbs cleaned.

Have a great weekend

I swapped this fzr 1000 exup 1993 for my motor from a Gypsy about four days ago... It has been hacked into some semblance of a street fighter... except it has no.. speedo, rev counter, temp...

Hi, FZRFZRFZR for this situation I would call my local dealer or reputable shop's service/parts department and inquire about any possible quick fix, answers, or parts inquiry. If necessary, transport your bike to the dealer or shop and have a professional technician take it for a test drive, if it is in running condition, and give you a written estimate of repairs and answer any specific questions you may have about your problem.

Yamaha rxs 100 can anyone help its been fouling up spark plugs and doesnt bulid up the revs smoothly ( build up the revs and it pauses ) can anyone help please thanks

1) Is the choke stuck on? Solution: spray carb with WD40 and make sure it moves freely when you pull the choke on and off.
2) are you using the correct 2T oil? It may be that it is pumping too much oil through. TIP: Take out plug and look at colour. if it is brown/tan it is ok. if it is white then there is not enough fuel going in. if it is black and sooty then there is too much fuel (choke stuck on) if it is black and oily wet there is too much oil (adjust the oil pump as per handbook)
3) Could be ready for a decoke. How many miles has it done? Solution: REDEX teaspoon down spark plug hole, turn engine on kickstart with ignition turned OFF. Wait a few mins and start up bike as usual,a few revs should chuck out loads of smoke and clear its guts out.

I have a 2003 ttr225 I can get the bike to start with the choke on ihave to let it warm up for an extremly long time before I can push in the choke . once the bike is warm and I hit the throttle hard ,...

Sounds like the idle circuit in the carb is restricted. The engine is running on the choke only. When the engine reaches a certain temp the fuelthat does get is more readily burned allowing you to back off the choke. The choke probsbly can't be completely opened? right? Fuel quality is also something to consider Oil content in fuel affects combustion temps and volatility. _good luck_Ned_

Not sure what happened i started my 97 cbr600f3 ran it on choke for about 45 sec. it started to die,so i eased the choke off it died and havent been able to fire it up since.any suggestions

Remove plugs to see what colour they are. If sooty then too rich / clean / install.
If wet then flooded, dry refit.
If clean and dry, starving lack of fuel.

Bike not firing properly, plugs fouled

If you used the choke to start the bike last winter, you probably fouled the plugs. Depending on the age of the plugs, you can either clean and re-gap them or replace them with new, which also have to be checked for gap.
Secondly, if you did not run the bike out of fuel after starting it, chances are you have some build up in the carb jets. New, clean fuel and Techron or Seafoam gas treatment will help if it's not too bad. Follow directions on the can. I personally used Seafoam but Techron is recommended by Honda. Be sure to mix per instructions, which on Seafoam is 1 oz. per gal.
