New Rider, 2007 Boulevard c50 problems

Hello,

I'm a new rider and certainly not a mechanic by any stretch of the imagination, so I find myself hear seeking some help with a problem.

I recently purchased an 07 Bouldevard c50 from a private seller which, at the time, seemed to be running just fine. He did say that he'd left some fuel in it for a month or two, so there's the possibility this is all because of bad gas... I rode it home from his place with out issue. The next day, I had some trouble starting it. It wouldn't start without applying a little bit of gas to coax it on. This sort of behavior continued for 4 or 5 days before a new issue arose.

A couple days ago, I noticed that while riding, I was struggling to deliver power to the engine and it began lurching while riding. Even while in neutral and applying some gas you can hear the engine rev up and then the rpms would fall off temporarily before reving up again. This would continue as long as I was applying gas. I had the battery tested, which turned out to be fine, and I added some SeaFoam additive to the gas to see if that might unclog any debris build up in the fuel system.

Last night on my way home from work, I was having some very strong jerking while riding, and I couldn't get the bike up over about 45 mph, regardless of gear. At a certain point, no additional power would go to the engine despite how much throttle I applied.

This morning, I was going to ride around the block to see if the additive had made any progress overnight, only to find that I cannot even get it into first gear! Applying more than a small amount of gas causes the engine to stall out. Letting out the clutch (while applying some gas to prevent a stall) causes it to stall out as well.

I'm at a loss at this point. I've ordered a service manual to hopefully disassemble parts of the fuel system to hopefully find out where there's a clog, if any, but until then I'm not sure what to do or if I'm even on the right path.

Any suggestions?

Thanks in advance!

[SIZE="a"]These issues weren't obvious when I bought the bike, and the owner may not have known that they were there. They may be nothing more than a clogged fuel filter, resulting from the fuel sitting in the tank for awhile. I don't think there was any malice in selling the bike to me, just the perfect combination of neglect and ignorance...[/SIZE]

So spit balling ideas i go way outside the box and let the really smart people here refine my thinking with Logic. SO dont listen to me 100% im just trying to shoot out some ideas.

1. Clutch and throttle cable adjustment. - Clutch cable would lead to the stalling and lack of 1st, throttle might enplane the lack of power and the pulsing you fee. once you get t your guide the steps are simple to adjust both of these.

2. Bad gas mixed with clogged fuel system. - i wold say pop the tank off empty it and start with fresh gas (also drain as much of the system as possible let it idle till it dies) mix in a carb and FI cleaner Seafoam is awesome but from what i know it is more for carbon buildup not fuel gunk(someone correct me if im wrong).

3. way left field bad Fuel pump - just seems like it has a problem delivering fuel.

Hope this helps narrow down the issue, and im sure more people will chime in and help out.

It's an 07 so it's FI. It's possibly a dirty injector.

I can head East or West, it doesn't matter as long as it's on 2 wheels.

Here's my 2 cents...

Do the 07's have the same fuel valve as my '01? They are vacuum actuated and the small vacuum tube deteriorates over time and loses vacuum and starving the fuel pump/engine of fuel, leading to some of the same symptoms our new member (Welcome from Boston!) is having.

Can anyone confirm this fuel valve is the same? THX


This work thing is beginning to seriously interfering with the much more important fun parts of life.
I need to get my priorities straight!

Fwiw, this is my pump filter assembly. I'm not sure if it's dirty or not by looking at it, but there was a sand like substance in the plastic piece containing the filter. Could be the sea foam additive or something else.. not sure. Any ideas?
