SOURCE: My XB-300Li motor cuts out after riding about a mile or so

Sounds like overheating alright. How is the weather? If its over 80 it might only be that. If it is cooler, then if you are running the recommended volt/amp battery pack you may have a bad temp sensor on your control board. If you are using a higher powered battery to boost speed then you will have to cool the motor or get a more powerful one that can take the load. I do not have that mode bikel, so I can not say if it is a common problem, It is not a problem with my 24 volt Lafree.

Spray a small ammount of starting fluid into the aircleaner. It will fire much easier and should start if your ignition is ok.

hi mate are you mixing the bike with 2 stroke if not buy a mixing bottle with a ratio of 32/1 on ebay and buy 2 stroke and mix it up with petrol and oil if not the engine will seize also take the spark plug out and give it a clean with a wire brush and check the gap is ok and then put it in the plug cover and put the plug against the cylinder and turn the engine over and see if there is a descent spark if not replace the plug good luck

I need help with my rm 125 1995 it has a perfect spark iv cleaned the carb and it don't start but wen I take the spark plug out then I kick it then screw the spark plug back in the kick it it nearly...

the way you explain this, the fuel and air mix is wrong, is the spark plug wet, if it is check the carb air mix screw. remove the mix screw and use a can of air and blow it out. before doing this remove the air filter and the spark plug then spray some wd (brand name) in hole and do again with the air can. then screw back in. leave the air filter off. and put spark plug back in and start the engine you will need to adjust the screw until you can get it to start. when it does give it a few good revs and keep it running for a bit. replace the filter and start engine and you will need to adjust the air screw till the engine sounds right again.

Take to long to start.. takes almost ten minutes of kick starting... electric starter wont turn over to start bike yamaha ttr 125

The TTR-125 Carburetor's Run Lean by design. Mine had the same issues till I found a post on on Carb and air box Mod. This is a good starting point on gets; 110 and 112.5 main and 17.5 pilot. But you must check spark plug coloring to make sure the jetting is correct. Check spark plug after the bike has been ridden for a wile. I also took out the stock baffle and replaced it with exhaust tip and now it fires up after a few kicks and worms up in a few minutes.

My bike wont start electricly.i have to bump srart it and it just backfires and after a few attemps it starts and then cuts out after 5 or 10 mins....

Try taking the jets out of teh carb and soke in carb cleaner and get a tiny wire and THOUROGHLY clean the jet holes. You may be able to see through the holes, but if there just a tiny bit clogged those holes are not allowing enough gas to get to the carb!

has the bike been sitting for some time? Sounds like a classic case of gummed up low speed jets in the carbs. Pull the carbs and clean then out.
