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

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 Thumpertalk.com 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!

To keep my engine running i have to pull the throttle obviously to rev it, else it the engine cuts out, and when i ride it splutters and cuts out, so i kick down a gear n it starts again but then dies...


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.
