K100 not starting

I just got my bike back after a 3 1/2 month of seperation (not my fault) and days after I got it she will not start. I've pulled plugs and checked various this and thats. So, here's the question: With a little over 40k on the clock can the Fuel Pump (mounted in the tank) suddenly go bad? I am picking up a new fuel filter today, but it's awfully odd that I road the bike 45 miles from the paint shop, parked it for 2 days and now it won't start. The starter turns like it should and the choke (idle advance- it's fuel injected) is operating, but NO crankie. Who's got a K bike and can tell me if I'm on the right path. I am not a mechanic- I just have limited mechanical aptitude. HELP!

I know on my E-Glide, I can hear the fuel pump wizzing before I start it, so I know it's working. Could you hear yours before and not now? Need to check 3 things. Air filter clear, gas getting to motor, and the spark plugs are sparking. All easy checks.

Urk, sorry to hear that Kirk! It's a tough one to guess on...but LR has the right top three to check. Spark would be #1 on my list.

I understand that the fuel pump/oil pump are on the same shaft and are notorious for blowing a bearing. My friend with 8 Beemers has his K100 torn down as I type this for that very problem.

Hope this helps and you get it fixed and achieve all the wonderful things you want in life. Have a nice day!

I notice we're all being so nice after PO'ing that skydive guy...then again, it is good old acecycleins!

Well, I was going to suggest your "dunking-it-in-water" technique, Ken, but ACI probably doesn't have any water!

We're really dry here as well, but nowhere near as bad as the folks in Northern Alabama and Georgia.

Cured by doing nothing!

OK- so the bike won't start for 3 days- I decide to poke an led flex micro flashlight inside the tank and see if the wiring has come loose. No loose wires, I close the filler cap and turn on the key for shyts and giggles and low and behold the [email protected] thing starts. Why? Have no idea. But, alas, she has sprung to life. So, I will close the agency early today and celebrate with a ride around the loop. Thanks for the responses- hope everyone has a wonderful weekend.

well, I'm late to the party again, you can hear the pump run when you turn on the ignition, sounds like you have a vent hose pinched and your getting vapor lock. I'd pull the gas tank and make sure all the vent lines are not pinched.

When I got the Concours, the guy I bought it from told me that every time it sat for more than a week, it was next to impossible to start. Sure enough, we cranked it till the battery was nearly dead to get it running the day I bought it.

When I got home, I started reading the owners manual that came with the bike. Turns out the pet**** had FOUR positions rather than the usual three. OFF, ON, RESV, and PRIME. Said right there in black and white: if the bike sits for a while, turn the petpenis to PRIME to start. Got to try it waiting for the rebuilt alternator. Started instantly after sitting 6 weeks.

Say what? The electric fuel pump is in the gas tank. Just what kind of a shaft would run from inside the tank to the oil pump ???

After nearly 200,000 miles of K bike experience my guess is that he simply needs new spark plugs.

Oops. You are right. It's the oil pump and alternator on the shaft. Never mind.

Remember it's dangerous to use a flashlight. Always peer into the tank using a match.

Lifting the fuel cap cured your vapor lock.

... to BMW owners it is also wise to remind them to inspect the rear drive hub frequently.

You just LOVE that BMW drive hub thing, don't you? I miss my Concours shaft. I'd love to see somebody make a line of drive pulleys and belts for DLs like the Uly has.

Yeah, I admit it.

I get a big kick out of all the people who pay premium prices for the pure myth of German superiority.

Someone makes belt kits for Triumphs. Why not V-Stroms? Start a letter writing campaign to one of the belt accessory companies by V-Strom owners.

There is a reoccuring post on the SV 650 forum with someone developing a belt drive for the SV. How far off could that be for the 'Strom?

"Ok." (chirp chirp...chirp chirp) "Good Tip."

Hmm,that's good news. I'll have to search the topic on the forums. As far as I know, the bikes are identical except for the obvious displacement difference and then some "features" like the hydraulic clutch. Frame, swingarm, etc. are the same. The pulley size from the Wee to the Vee would undoubtably have to be different, given the variance in gearing, HP, and torque.

Thanks for the tip!

Ken,

This guy apparently focuses on Triumphs, but you can see the possibilities.

Thanks Pushrod. I checked it out. I saw such great results with belts during my time at HD that I'm a big fan.

whats wrong with chains? you can get those gold ones with anodized black sprockets and they look cool as can be specially on a blue Suzook with black wheels and an alloy swingarm. it's the asthetics you see, it has to look cool as well as actually work
