Question about 2003 Yamaha DT 125 R

1 Answer

I have a 2003 raptor 80 that spins over but now will not start. It started before consistently, then sometimes,now it does not. I checked spark, charged the battery, changed spark plug and ran fuel system cleaner through it. You can hear and feel the air coming out the tailpipe when cranking it. Gas is in bottom of carburetor and will not start even with starting fluid. You can even feel it pulling air in through the intake air supply as I removed that to check and verify it was getting air flow into carb.

Raptor 80 started turns but does not engage motor


sounds like the starter clutch is bad. the rollers get worn or the sprag gear gets worn so it will not grab and start the motor. check that out. you will have to take the engine side cover off to see it.

Yamaha 2005 raptor 80- clutch not engaging


ever put a clutch in? 100% sure you have the discs in right? It could very well be that it is adjusted too tight and won't release the clutch. Usually happens when you go from a bad bad over adjusted clutch to a nice new one.

2003 kia Sedona won't. start


If this is a sudden occurrence and nothing suspicious happened prior, you most likely lost either gas or spark to the engine. You need to check for both.

Do you hear the fuel pump in the gas tank buzz on for a couple of seconds when you turn the ignition key to ON? Unless the fuel pump turns on and puts gas under high pressure at the fuel injectors, the engine cylinders won't get gas to start. Correct fuel pressure is crucial to know if you have a fuel pump (or fuel filter) problem. If the pressure is correct, it is probably not a fuel problem but a spark problem, although there are less common instances where a fuel injector circuit may malfunction.

The ignition system not producing spark at the spark plugs is the other common problem of no starts. Buy a cheap spark tester at a parts store, plug it into one of your spark plug wires, then crank the engine over and watch for a strong blue spark. You might need a helper to do this. If you see a consistent spark, the ignition system is probably good, although you should probably check more than just one plug wire-sometimes one bad ignition coil in a coil pack will cause no starting. Good luck.

Have a 2003 ksf-80 qaud has good spark and its getting fuel but it will not start. the plug seems to be wet from fuel each time i check it, this problem started after one day the kids road it and the next...


i believe that model quad, like many smaller kid quads, have an electronic choke. sometimes the electronic choke valve stick. try unplugging it from the connector or tapping on the side of the carb with the back of a screwdriver, that sometimes work. or you might just have to replace the choke.

Cant start my 2004 80 ws raptor


Most likely, the head gasket is blown.
Check the compression on all cylinders that you can reach.
Compare results. If 2 adjacent cylinders have low compression, then that's the head with the blown gasket.

Hope this helps!

Get a compression tester to see if she has plenty of compression or take spark plug out ,put your finger over plug hole and turn engine over. you should feel a pressure forcing your finger away.
