No carb change has fixed this...that is why I think it's not the carb.
Unusual. I'd think about a leak down test just for laughs. Any oil use?
This sounds stupid ... but are BOTH plugs working? I left one off once by mistake ... bike runs but slightly 'weak' . Since you've been through so many Carbs ... maybe NOT carb related. I'm stumped. Best of luck sorting things out.

Grifter, ER70S, Jayhawk, et al locals - I can pay in beer and whiskey so you won't have to pay taxes on it.
I'm in California ... but will help anyway I can. We've got several great DR guys in those states ... hopefully they'll chime in and can help out.
What is wrong with your bike?

(Love the Beer and Whiskey offer ... but you forgot GUNS! ...just kidding ... reminds of when in Antarctica ... the brass would check in with us over HAM radio. Before signing off they'd ask "... hey, anything you guys need down there?" Yea ... Whiskey and Guns! Somehow the big bosses were not amused.

My bike got 54 us mpg first tank after lowering the needle a notch from the 3rd groove. Got about 45 before that. That said, adding sails (wolfmans) and 50 pounds of shit has brought it back down to about 47. My first thought reading the weird behavior was a vacuum leak- like a torn boot from the carb to the head? To cause so much variance though it would have to be big, and that doesn't explain the wide range in gas mileage. Mileage variations scream carb, but you seem to have eliminated that. Maybe some issue allowing the cam timing to change thereby making you use the throttle more, but it would still be more consistent (cam chain jumping a tooth). The ping screams lean or too advanced- maybe a fluke problem with the cdi? Your issues do sound strange indeed..

Yet another set up question.....

One of the last jobs to be done for the DR is getting power for the following up at the bars.

Heated grips
GPS
LED Spotlights
Cigarette lighter - marine version?

Any advice on the best way to do this? Was thinking of a fused power source from the battery via the ignition switch to some sort of switch block and then running each of them off that? Having never done this sort of thing Im guessing there is a better way to do this.
something like this is nice if you can afford it and find somewhere to locate it. means you only have one extra wire from the battery to the front of the bike, can use properly rated fuses for each device and can easily choose if you want each thing running off switched or constant voltage.

You can get a three fuse block from many auto parts stores for $10. I got mine from O'Reilly. I think Pep-Boys have them too.
Put it under you headlight fairing, one wire to the battery or pick up a live wire in the mix up there.

How new can it be considering it's already plated?

I'm a fan of Eastern Beaver stuff. Ready to go, your choice of fused circuits, etc. Yeah, you can build one but I'd rather not experiment with the electrical since I'm just not comfortable with my skill - or lack of - level.

New but sold I guess, that's pretty standard here.

Yes, I thought that it looks like a Staintune with the STD heatshield. It hasn't really come out in the pic but I could see behind the side panel where it went down to join the header pipe it wasn't like an aftermarket pipe it had a CAT on the end of it like a smaller version of the original. And it's not listed as a used bike on their website so was assuming it was new.

Wish I could help you with this but I work on my own bikes, I'd think there'd have to be a decent shop or two in Albuquerque, I can't vouch for any in Taos or Santa Fe.

This may be silly - I am no mechanic. I had a similar problem with a torn petcock diaphargm on my Honda Superhawk. The bike would smell of gas. It would run rich. I would get much worse fuel mileage as well (30mpg). It was a $20 fix rebuilding the petcock which was buried under the tank on the superhawk. Mileage immediately improved from 30mpg to about 40mpg. Does this bike have it's original petcock? You can find a cheap new aftermarket or Yamaha petcock (I think Raptor works) to check. Just a thought
I have the Raptor (bought from Procycle).

Does your friend want some work?

Replaced the boot....

I almost picked up a cdi on eBay but I have a 2nd DR now so I can use that bike to troubleshoot the first one. I just have zero time with work/kids and training for upcoming Bike MS ride.

Hmmm, that gives me an idea....maybe I'll take all the entire intake/exhaust parts from DR #2 and put it on DR #1 and see if mileage stays same. If it does, then I think you could say it's either electrical or the engine and I'll then move the CDI and ignition coils over and see if it stays the same. I would think at that point I can safely say it's the engine. Otherwise, I'll know basically what part 'fixed' it and can replace that on DR #1. I am still willing to pay someone in the Boston area to do this...just too busy right now.

The only mechanic that I can vouch for is Dillon @ Zen Moto in North Scottsdale. Good luck with your move, there's some great riding out there.

Isn't that a DRZ250 tail light? And, it looks like the turn signals are mounted directly to the rear fender. Lastly, the license plate support looks totally different from o.e. I'm thinking that's a modified DR and not brand new.
