WHOA! Not good. Hopefully you're safe and the bike is ok. How/why would a chain pop off?! Maybe start a new "build thread" and post pics etc. I am thinking about doing the same to cover the things I've been doing and will do moving forward. I'm very interested in seeing your progress, as we share a very similar bike. Best of luck

Are these bikes' back wheels as easy to move forward or backwards as easy as the enduros? Was the chain stretched to beyond useful/need a new one?

There's hashmarks on both sides of the swingarm that help get the axle mostly lined up, but it's always a good idea to check by measuring! The chain seems fine for now, but I will most likely replace it fairly soon so I have an excuse to buy a new sprocket! |

Does your bike have the EGR doodad? Since my bike has dual exhaust, I had 2 of them but they weren't hooked up to anything! The tubes from the egr units were just tucked up under my gas tank, there's also a connector near my seat that isn't hooked up to anything.. Still trying to figure out what it could possibly be! I definitely recommend taking off all the plastics and making sure EVERYTHING is hooked up!
And I also have the carbs running wide open, no airbox hooked up.. I've noticed a decrease in performance. And by "decrease" I mean at WOT it tops out at 7K rpms and it just feels really laggy. I'm assuming it's because it is now getting too much air and not enough fuel? I figured the jets were designed to be used with the restriction of the air box. Can anyone verify this for me? |

What are you using for air filters?

Well it seems to be better, I took the gas tank off and found I had a vacuum leak! Plugged the hole and it seems to be doing great now! But I did end up putting the box back on until I can get a couple Uni filters and bigger jets! But is there any size jets you could specifically suggest (main and pilot)?

I was just running the carbs with no filters just messing around, but I know it's not good for the engine so I went ahead and tossed the box back on!

You either need to install the original air box, or add external air filters. If you ride the bike without air filtration, you will add dirt to the fuel/air mixture entering the engine. This dirt will damage the intake valve and its valve seat, causing the valve to recede into the cylinder head. You can only experiment with carburetor jets after you have installed a good air filtration system.

Start with two sizes bigger than stock for starters.

Also, my bike has no air box. I do have a small filter attached to the end of my carb. Was yours different? Pics?
