I have a 2004 polaris 330 magnum. It doesnt want to start well. hot or cold it wont start properly. It just grinds some and may eventually start. Runs good after starting. Also does it with fresh gas. I'm thinking maybe spark plug may need replaced. Its got 400 miles on it. Also curious about engine braking. This one doesnt have much or any. Is there anything that can be done to help this out. It needs to be safer. Thanks

 

Is the air filter clean? If its dirty and plugged up, thatll make it hard to start.

 

do u mean it grinds wen u begin to turn it on? if it does that means ur starter might be going soon...atleast thats wat our 400 did before it locked up

 

it tries to start but i dont grind it long,then i will try it again and it will start. like a vehicle when its out of gas. i got me a spark plug today. going to try that first. i will also check and clean the air filter. after that i will not know what to try. i've had it since february and it has been in the shop 5 times because it would quit while riding and then backfire. it would do it while starting to come to a stop. had it back about 3 days and it hasnt done it yet.keeping my fingers crossed.

 

ya i think its the starter...our 400 did that it would grind for 5 seconds when ur trying to start it then u would stop wiat a sec then do it again and it would go grind gridn grind then start right up. and wen its warm it just makes the gridn noise like once and starts

 

ya it is the starter the same thing happened to my 400sport on the 2 strokes polaris puts the starter on the bottom of the case to it is exposed to mud and water if the seales go bad water gets in the starter not sure if they do the same thing with the 4 strokes, i just took mine off to save weight but if you just like to trail ride you could get it rebuilt or buy a new one
