WR250R Won't Start

Facts:

WR250R - Supermoto'd out.

Bike was put away last November with a fresh full tank of fuel and put in Stabil.

Battery was pulled out and brought inside to warm storage and is fully charged.

Bike turns over really well, but isn't firing. Fuel pump does make the priming sound.

Any thoughts as to why it isn't starting. This is a friends bike and I haven't looked at it yet, these are the conditions he's describing to me. I'm checking it out tonight.

Prior to winterizing it, bike fired up stupid easy, consistently.

3xxxx miles on it.

Any thoughts?

water in the gas

stabil usually will take care of that, unless they got some funky gas when they last filled up?

spark?

and at that mileage there could be some loss of compression. there was a thread recently on a wr that had really low compression with that same ballpark mileage.

Bikes with bad fuel pumps will also act exactly the way you are describing.

You can hear it prime, it will crank over just fine, but it won't start.

Of course check all of the simple fixes first. Spark, bad gas, air box, etc., but it certainly could be a bad fuel pump.

Service Honda has about the best prices I've seen on replacements.

Typo on the mileage... its 3xxx whoops....big difference.

Thanks for the input. I'm going to look at it tonight. The owner isn't very mechanical sooooo I *get* to work on it.

He's my boss...so in a way, you could say I'm wrenching my way to the top.

I had the same thing happen to me, I took the whole bike apart, checked the spark plug and what not. Then I read that starting the bike with the throttle wide open might work. Tried it and the motorcycle fired up with some sputter the and died, I tried it again and it started fully this time. Ever since it has started no problem.

AT almost 40,000 miles (2008 model)-----------mine has never failed to start.

But about 3 or 4 times since new---maybe after sitting for a month or so in cold weather without starting it------it didn't want to start. And I got it started by holding the throttle wide open.
Seems like once I remember I had this problem after washing it at the car wash and not completely warming it up to boil off any water on the motor. Now---after washing I always run it till it gets good and warm before shutting it off. This is a good idea for any bike.
