Hard starting 1 Month, 2 Weeks ago  
Ok, I got this beautiful 07 sitting in the garage that I just picked in seattle, but it's being a real pain in the @ss to start. Granted it's cold out there but it should fire up easier than it does. With the enricher in various positions I basically get nothing and throttle position doesn't seem to matter either during the start sequence. But yesterday I'm fooling around and notice that if I twist the throttle to activate the accel pump, it wants to fire? With enough pumping it eventually fired up and once it's running I notice that pulling the enricher doesn't seem to make any difference in how it runs even after it's warmed up. Now my gut tells me I've got a massive intake leak which would explain most, if not all of the symptoms I'm experiencing and might also explain why the pipes are so discolored. Even though the bike has less than 6k miles I'm planning on pulling the intake manifold to have a look but is there anything else I should investigate while I'm doing that?

I got maybe half way through your description & my first thought was 'leaky intake'.

I'd give that a shot of carb cleaner while trying to start it.
The fluid will (usually) form a temporary seal to correct the air fuel mixture.
If it still won't start but you even notice a difference I bet that's at least part of your problem.

I'd also definitely give it a massive shock treatment of Seafoam to knock some snot loose.
I'd bet dollars to donuts there's some seriously crappy gas in there with so few miles in a 2007.

This fits in here, right? I mean, I can make this fit in here ... right?

Start simple. Drain all fuel and clean the tank and carb. Seal the intake manifold and install new exhaust gaskets. Dont rush and start making carb adjustments.

Make sure the enricher is working other than that continue down the path you are going. My thought is that if the enricher was working at all it should make a difference when pulling it out, especially if you just have an air leak.

Yeah my brother suggested the same thing and I concur. Since the enricher appears to make no difference in either the starting sequence or after it's running I'm already suspicious. The downside to buying a bike that's been "Customized" means finding out what they might have screwed up along the way.

Damn, and I just filled the tank to put it away for the winter. I'll get a set of gaskets on order and go through a checklist come springtime. Thanks!

Drain that $15 of gas into a can and use it in something else over the winter. Then you can fix the bike over the winter.

I was reading your other thread about when you got the bike. You mentioned pulling the baffles out, so I'm assuming you started the bike at that time 'cause you mentioned no more rattle. Was the bike hard to start then or is this a recent development?

Hard to start from the get go, but I figured it was just me not knowing it's quirks and an empty tank of fuel. After I fueled it up it was obvious there was something else going on because even hitting it with starting fluid didn't have much of an effect. That's when I discovered rolling the throttle on multiple times in quick succession got it popping. So either the enricher isn't hooked up or I've got a massive air leak that requires the use of the accelerator pump to overcome. Could be several problems at the same time causing this to happen...it's just going to take some time to get it ironed out.

My guess is you have old ethanol gas in the tank, fuel pump, fuel line and carb that has turned to gell and won't let the new fuel move through the system. Don't think too hard! Things don't get out of adjustment by just sitting since it was running OK. When did the seller say it last ran well?
