  1. I'm looking for information on how to route the carburetor hoses on a 2005 Honda XR650L. It's a California model, but it has the smog stuff removed and blocked off. It's uncorked and has an FMF slip on exhaust, along with Dave's Mod done. It would be nice to have a diagram, but pictures or even just an explanation would work. Just looking to see how best to set up the carb hoses. Thank you

    DR250SES Fuel Problems

    Okay I've read a bunch of past threads and I think I have this down but need some confirmation as I am a relative newbie. I bought a 1994 DR250SES third hand. It has an aftermarket Acerbis desert tank. Ever since I bought it it has been sluggish starting in 1st gear, at least until RPM's are up. A couple of months after purchase, and not a ton of riding, it started really hesitating, stuttering you might say. I have pulled and cleaned the carb 3 times, inspected the diaphragm (fine) and each time it seems like its fixed, only to start the whole thing over again. I have even removed the petcock and inspected it to see if the filters were blocked. They were fine. Yesterday, on a dirt ride with my son, it really started acting up, but really only after it got hot. It would stutter and hesitate on acceleration. We hit the pavement for a return to the vehicle and it just flat out died, and no amount of holding the clutch in and revving would bring it back. It seemed out of fuel. I let it sit a minute or two, it started up, and I got it to the car at high speed, but it still hesitated in first gear when I started out. So--I think this is my problem: The aftermarket tank does not a have a vacuum line on the petcock and the vacuum port on the carb has been blocked. The boggy/hesitation in first gear especially seems like a symptom of the lack of vacuum, since I understand that is what the vacuum line is supposed to address--giving a quick shot of fuel to the carb on quick acceleration when the carb can loose vacuum momentarily (is this right?). As to why it seem to be more fuel starved after it heats up---I am at a loss unless it too is related to the absence of the vacuum line. Am I right?
  3. My dad and I have two XR650Ls, one is a 2005, the other is a 2008. We've been trying to get the carburetor tuned, but we've been having some trouble finding the right way to route all the hoses. Both of them have had Dave's mod done, and they've been uncorked and have an FMF Powercore 4 slip on exhaust. They're jetted at 55 and 158 at about 6,500 feet above sea level. Fairly often, when I'm cruising around 40 mph, the exhaust pops and the bike loses power for a split second. That's the main problem that I've noticed. Also, on my bike, if I let off the throttle without pulling in the clutch, it pops a ton. I know some popping is normal, but it seems like it's a bit excessive. If anyone has any tips on routing the carburetor hoses, or any other tips to get them running right, it'd be greatly appreciated. Thank you.

    DRZ wont stay running

    I was riding the other day when my DRZ sputtered out. I pulled over and found the vacuum hose disconnected from the petcock. I reconnected it and rode home. Fast forward a few days, left the house and the bike sputtered out again. This time not only was the vacuum hose disconnected, it was gone! Pushed the bike a mile back home. Noticed the petcock leaking a little fuel and the smell of fuel in my oil. Ordered an OEM petcock, installed it, drained the oil and put in fresh oil. Installed a replacement vacuum hose. New spark plug. BIKE STILL WONT STAY RUNNING. It will start if I prime it but wont stay running, sputters out after a moment. Is it my carb? Could the vacuum hose coming loose while riding damage the internals of the carb? I drained the float valve, fuel stopped coming out after a moment. It was idling fine before all this. Fresh oil, new petcock, vacuum hose intact. I'm pulling the carb tomorrow. What should I be looking for? Thanks in advance.
