Well, I do believe my carbs are running rich and that is causing my non-starting issue. I changed the plugs today, and my old ones were pretty black. Since the last time I pulled them was at night to check for spark, I guess I didn't really see just how black they were.

Also, I pushed started the bike to get it running and then parked it in the garage while still running. When I rev it to 5-6k and hold it there, then blip the throttle up to 10ish, there's a nice big puff of dark unburned gasoline coming out of the exhaust. Yummy.

So, since I know nothing of tunning carbs, I need to take it somewhere to get the carbs tunned up. I can only think of Colemans and possibly Whitmans Suzuki in Manasshole. MFI seems very anti Suzuki, so I don't really want them tunning my carbs if they don't usually work on Suzuki's to begin with. Any other suggestions as to where I might take my bike for some carb work?

Did your bike run right in the past? If so, they don't need tuning, probably just a good cleaning. How's the air filter? Dirty? Pull it out and see how the bike runs. Let me know what happens.

Bike ran fine, never had any misses or dead spots in the power band. It never had any other problem besides having a harder and harder time starting up until the day it just wouldn't start anymore.

I'm sure the filter is dirty. I haven't changed it in the 2.5 years I've had it. Yes I know I'm bad for that, I was planning on buying one anyway since I've replaced everything else.

I'll pull the airbox/filter tomorrow and run it and get back to you.

Ok, took the stock air box/filter off (which is no small feat) and the bike starts up! Yippie!!! It runs rough, but I'm sure thats because the carbs are nakid with no filter. The bike still needs the choke open to the first possision to get it started, but it starts.

The filter is filthy. Like a used porn star kinda filthy. I'm on my way out to pick on up from Whitts Suzuki in Manasshole.

buy a new filter dingus!


Get a stock one. K&Ns are not so good on those bikes.


If you drink and ride, I have no pity for you. At all, ever.

Yeah, I feel quite the dingus right now. And yeah K&N's aren't really worth it unless you're rejetting.

So things look fixed. My old filter was nasty, new one looked sexy. In fact, the old one was some sort of spunge material, while the new one was your typical rippled papper element filter. After install, the bike started up without the choke!!!. That alone is amazing. I did have to put jumper cables on it, due to my battery getting abused with all this starter action. The battery would not start the bike on its own, it would only turn the starter over.

So now, the battery is on the charger and hopefully it will start up just as easily on its own. I do have to say though, I think my filter got clogged on a specific road 2 weeks before this all happened. Joplin 619 had just been paved on the side I was riding on and I didn't notice it at the time, but there is a heavy black substance sprayed under my tail and up on the back of my battery/shock/swingarm area. It looks like if I had been doing a burn out. And my stock air box opens facing back toward the rear tire. Just a guess.

Either way, thanks for your help Travis and Twiggy.
