3/4/2021 3:44am Yep it was the co sensor I talked to the local Yamaha dealer and they said it's a factory fault in some of the the 2020 wr250f they went 10% richer from the 0-2000rpm range and it's completely fixed. No backfire today even when I was running the Keefer map, even starts way better then it used to.

I had that same issue on my WR 450 and mapping would not solve it. I had to take it into the Yamaha dealer and they used their diagnostic tool to change the CO setting. My issue was popping going downhill and once they changed the CO setting it made the popping stop and also made it easier to start. Their Yamaha tool they used changes the setting from 0-2000 rpm and mapping only effect from 2000 or 3000 rpm and on I think. So in the end they made it richer from 0 to 2000 rpm. All the 2012...

I currently am running a very Rich mapping to stop this but feels like I have really dulled the power . Has anyone else experienced this problem with an aftermarket...

I took a chance and tried the 53 coming off the AT81. Terrible off road tire. I ride/race eastern PA single track with roots and rocks. Does not work, period. No grip at all. Went back to the AT81 and all is well again.

I've been running the rear 120/80 on my 450 at the track for Mid-Hard condions and those tracks almost always have sand sections. The tire works excellent at 12.5-13 PSi or with a Soft Bib. I run them in the front out in the Dez or on true 'Hard Pack' & they work pretty damn good. For all other conditions, I think Dunlop fans should probably run the 33 frt. My normal set-up is 33 front/53 rear. However...the BEST "all around" tire for my money? Metzeler Mid-Softs for about $145/set delivered to my door from RMATVMC. These tires work well...
