I suppose it is a possibility and wont take much effort to eliminate. Ill replace the entire fuel line with a piece of clear line i have left over so i can still watch for fuel flow.
Thanks for all the replies.

Now you know why I don't take pictures in my garage, the same people that look through your medicine cabinet when they go to the bathroom...

Well the chain guard is from a DRZ that I got a while back from Ebay by mistake... and wanted to put it on the KLR... So I got another swing arm and took it to my local welding shop. I had a friend that took lots of pics of how it was attached to his DRZ... I took the Swing arm, Chain Guide, rear wheel and the pics to the shop.

They got it done but I wasn't real happy with their work. I figured that a professional welding shop would have done a better job. I use to weld aluminium for a living...if I had the equipment I could have done it myself and done just as good or better a job then what they did.....

It is what it is... F it... Its done...

Back to fuel flow...

How does the fuel flow out of the tank if it is a vacuum system? I turn my petcock on and no fuel will flow until you start the bike and then it flows. I see a number of posts where they say the fuel flows on gravity...have they gutted the petcock or something along that line?

Thanks for any replies

Yep. Vacuum line opens diaphragm valve for fuel. You can gut the sticker or get a petcock for a 660 Raptor

I see, so they're making it into a gravity feed system. Thanks!

It is a gravity feed. The vacuum petcock shuts off the flow when the engine is not running or, hence, the loss of vacuum.

By the way, when open full throttle riding into a strong headwind on the freeway (80 mph) will cause the bike to feel like it is starving for gas, which I have attributed to the vacuum diaphram.

I haven't gutted my petcock because I like having the vacuum shutoff.

I disabled the vac fuel cutoff on my 09 with no issues no matter how full the tank is... Google, "KLR hurricane mod" and you'll get several write ups on how to do it. Never had an issue on mine so it sounds like you have a vent issue.

Good luck!

Lots of folks toss the vac petcock cuz it's a possible point of failure. Manual works just fine. It all sounds too complicated to me. Just burp the tank if you think it's a vacuum lock. Extra key in cap and pop it open when the engine sputters. If Engine revs back up then you got a vent problem. -FB
