XR650L - Pitkin to Buena Vista - Hancock Pass COBDR 

Thanks for the clarification!

@@Megakoolguy357 You're welcome. I ride the area quite a bit, since it's only about aa 2 hour drive for me.

I have thought about the forks, but I just can't bring myself to abandon the old style forks. They are too reliable, cheap, simple and work well enough

Thanks! My tried and true combo is Daves mods with 55 pilot, 158 main, and shimmed needle. It runs great to 5,000 ft, okay to 8,000 ft, second gear tops for climbing hills at 10,000+, and first gear only for climbing hills over 11k. The key, in my opinion, is to use an adjustable pilot screw and shim the needle a tiny bit lean. That way your wide open throttle (where predetonation is most likely to occur and heat builds quickest) is still rich enough at lower elevations. Keep the throttle at 0-50% open and you'll be cruising as best as you can be up high. There is a bit of a hit in performance at your most common elevation when jetting for elevation change, but I'm willing to sacrifice that for a bike that can take me from the beach to the colorado nountains.

@@Megakoolguy357 Thanks, that helps alot. I appreciate you taking the time to thoroughly respond.

Lectrons are stupid expensive. I have read several posts where people say they can hurt the powerband on 4 stroke engines. I imagine that is because they are designed for use on 2 stroke dirtbikes or MX 4 strokes. The stock carb does well enough for my taste. I think a grand misconception is that bikes with a miracle carb or fuel injected bikes are immune to elevation changes. That is not the case. For a more detailed explanation, check out Fortnine's video on carburetors and fuel injection. In short, all engines are affected by elevation changes. To what degree that affects the ride is dependent upon a huge variety of factors, but the fuel system is definitely an important one. If I could get a Lectron for $400, I would certainly try it out. I just don't think that it would ever be worth $800. My XR runs well from sea level to 6 or 7 thousand feet. After that its performance is drastically decreased, but you can absolutely jet for bias, or pick an ethanol fuel if you plan on riding in an environment with less air. I can reliably ride to over 10,000 feet with the stock carb. Is the bike a speed demon at that height? Nope. All that said, I would love to find an XR with the Lectron already installed that would prove me all wrong. I want to be wrong so I can install something that will make a 10% improvement on my machine. It would also be interesting to see if I could modify the stock carb or needle to improve performance. Modifying the stock carb beyond Dave's mods seems like a lost art. It sounds like something a guy would have done in the 1970s. I find that there are many times where the old ways can work just fine, though. Thanks for watching!

Thanks! I found out later that the kit I used for my rear shock was missing the top bushing and my bike was lowered with an aftermarket link. I can't believe how well it did considering that lol. I fixed it for the UTBDR. We rode the COBDR in early August and the UTBDR in early July. We got extremely lucky with the weather both times. You can ride around Moab during more of the year, but pretty much all the BDR routes have passes you will want to ride in the summer. It sucks that you won't be able to get out for a trip this summer! Glad you got the XR out! I am thinking about trying to get mine out of the shed this weekend, but we'll see what the weather does.

@@Megakoolguy357 Yes, not enough seniority, so looking like March or April ? No idea where I’m going but I will follow the warmer weather for sure. Honda was so cool to ride, I messed up the video?? Oh well try again. 🤣😂 I will get the Lexx exhaust on this week and hopefully have a quieter XR650. I enjoyed the ride, lots of side by sides, they are everywhere out here too. Great to see you posting again.

Thank you!

I have a Clarke 4.7 gallon tank, but I think the COBDR could be done with a 4.0 gallon tank as well. The stock tank probably isn't enough. I run IRC GP1 trials-type tires as they are still reliably made in Japan. They are just a tiny bit better than the Kenda k270.

I don't appreciate the attitude in your comment, but I'll answer it anyway. The BDR routes are quite well established at this point, and there are many places you can jump onto and off of difficult sections based on weather. My group has been quite lucky with the weather each year, but we have all been in it before. Everyone has his threshold for difficulty and danger. We had a great time in Colorado, and I remember this as one of my favorite days.

@@Megakoolguy357 hahahaha.... Enjoy yourself out there!
