I have a atv tgb blade 250 when I go to put the work she don't work but the engine runs, but I have noticed that the candle is not current. what can it be? Could be the cdi?

you bumped the kill switch on handle bar.

See if the videos or articles help. It seems an electronics issue though, a relay perhaps.

most starters are not sealed as such but collect oil from the back of the flywheel ( torque converter) where the crank shaft rear seal has failed
oil in a starter interferes with the brush contact and causes starter operation problems

Shouled tell u on tyres

what do you mean she dont work?

put rocks in where? if the gas tank then your petcock filter is probably clogged

clean the carb. look for air leaks.

Do you mix oil into the gas?? Is there a place to check the oil (a dip stick). Is there a special place to put 2 cycle oil for a self mixer?

If you don't mix the gas with oil and there is no special place to put 2 cycle oil, you have a 4 cycle engine.

If there is a place on the side to check the oil level, you have a 4 cycle engine.

Next question will be ... how do I check the transmission oil? If you have a 4 cycle engine, the engine oil is also the transmission oil ... rule of thumb.

You are showing a picture of a motorcycle and asking a question about a ATV, but not mentioning a model number. I don't think Yamaha is currently making a 2 stroke engine for their ATV's (there are several sizes - not including assorted models for sale around the world ... and I don't know where you are writing from (and please don't say).

Maybe the best thing for you to do is call the Yamaha dealer on Monday morning and tell them the model you have and ask the question 2 stroke or 4 stroke. There will be no more guessing on your part then.

Make sense?

Thanks for your question @ FixYa.com
