Try looking over there.
I don't think the petcock I bought would fit yours as it's for 2007 and earlier tanks.
If it is the same petcock and you have trouble finding one, I can sell you this one.
After all, I won't be using it since the tank I bought was only a backup tank in case I mess my tank up.
And even then, I could take the petcock from my tank if it doesn't get damaged and put it on the backup tank.
I just went on that auction site and found a brand new on off res gravity for $29.99 with free shipping. Eagle mikes was going to be $32 with shipping. Oh well, I tried him first but had to go elsewhere.

Yup. That's what I'm using.

That's what I'm using also.

I chose a 660 Raptor ATV year at random from the list of years on the Ron Ayers web site.

The 660 petcock has a shorter main intake (i.e. less reserve capacity) so I lengthened the main intake with slip-fit brass tubes from the hobby shop. Glued with "Seal-all" chemical-resistant glue.

Need help ASAP

I think I screwed up big time tonight. I have been commuting 25 miles to work every day and usually check my oil as often as I can. I have an 08 that has only 5000 miles on it but it has had a rough life sitting outdoors due to no garage. Anyways, I totally forgot about checking the oil this week when I filled up with fuel. I left work tonight and had no issue's. I ride on highways the whole way so I can't hear noises that great. I pull off my exit and stop at the red light and hear a ticking noise. The bike stalls and cranks back over REALLY hard and finally starts back up. I limp to the gas station and ended up putting in.......please don't hate me...... 2 quarts to bring it back up to full. It started up easy again but still has the ticking noise when running. Speeds up when I give it throttle and slows down when it idles. Valves must be ****ed. What do I have to do now to get it back to like new condition? I see the 685 kit but that doesn't help the valve issue. This is my only vehicle right now so I need help asap.

Men say typical catastrophic oil-starvation involves trashing the machined camshaft journal surfaces in the head . . . probably would require examination to determine if this is the case . . . most expeditious repair mentioned in this instance is head replacement, camshaft(s), also, if necessary.

More optimistic outcomes may be possible (a "ticking noise" might result from the greater catastrophe). Hope the problem's easily diagnosed and corrected..

What would I need to do if the worst case scenario is true? I am trying to get an idea of what I need to order. Am I better off buying a whole new head for $700 and just bolt it up and go or are there easier options?

You need to pull the valve cover first....worse case your $700 option is best. Though you'll need piston/rings as well at min.

Well with having to add 2 quarts you may have more than just upper end problems. Your oil also lubes your trans and clutch, and crank bearings. Hope it is not any of the latter problems.

If it turns out to be as bad as all this "worst case" scenario, I think your best bet is just buying a used motor off ebay. I have at times seen them for about $500 or so, with probably $75 in shipping. Would be cheaper than just the head, not to mention piston and all the other stuff that could have been messed up in there.

But, that is my opinion of the worst case. Take it apart and see what you can see, or post up pics.

Trun Signal T'shooting

Gents

I've got an 05 KLR650, equipped with an Afrika Light Switch Assembly (allows the head and tail lights to be turned off).

I have no turn signals whatsoever -- thehy do not come on when the switch is activated.

I'm preparing to dig into the scoot, but want to know if there's a common failure mode for the signals on these beasties (new to KLRs, not to bikes or wrenching)..

Thanks!

I started pulling my bike apart and noticed the spark plug was really loose so I had a .01% chance of hope. I tightened it back down and fired her back up. Tick still there. Removed all of the parts in the way of the valve cover and took it off. I am not a crack mechanic but even I can tell it was bad. Exhaust cam on right side is toast. The other side of exhaust cam looks ok but that really doesn't matter. The other cam is stil in good shape so that is somewhat good news. Journal on the head is toast. Break the bad news to me. What do you think the cost will be? should I do a 685 also because of chance of damage to piston? Keep in mind I need the cheapest way out of this. Have a look.
