I was riding it around my house then the engine cut out and I thought I ran out of gas so I checked and had over half a tank... Tried starting it and won't start I drained my battery trying to start it. I don't know what to do. I thought I might of bumped the kill switch but nope... Please help

Just changed the spark plug and still doing the same thing. The old spark plug looked nasty

once the stock titanium intake valves start wearing good, they will tighten up so fast you wont even know what happened and it wont start. Happened to me a couple years ago. Not saying this is what happened, but good possibility if you still have stock valves

Push start it, it starts up time for valve adjustment/new valves.

but new valves were JUST installed about 3 months ago...! :angry: I clean my uni filter every 2-3 rides.
btw @ pwalston25: They are stock valves. If this is the case and the valves are worn then I will just go ahead and throw on the ported head from racers edge with +1 ferrea valves+kw springs that i bought off of mypowersports2012

Im sure they need to be adjusted then. When I got my valve job done, they had to be adjusted at about 20 hours. Its no big deal

How many hours since new valves? Figure this: I just had my whole head redone and have approx 10 hours on it. My intakes are just a smidge tight...

Problem fixed. The needle was all corroded and now it got cleaned and now its good as new and running again. Should I run Seafoam in it from now on?

I wouldnt run seafoam all too much, it will clean stuff nicely but it can cause problems should you use too much.

I would make sure to use different gas and not let any stay in the bowl if you park it for awhile.

So are you saying that I can use seafoam all the time but not too much of it? or just every now and then would be fine?

No. What Im saying is I wouldnt run it all too often. I generally put about a good splash in my gas tank once a season and thats it.
