WR450F PISTON REPLACEMENT? Dear Mr. Know-It-All, I am a slightly overweight, 50-plus-year-old slow guy who has enjoyed my 2005 Yamaha WR450F since purchasing it new in 2004. I religiously service the bike myself, including regular oil and…

STUFFED POTATO Dear Mr. Know-It-All, My 2003 KX125 has started running as if someone stuffed a giant Idaho spud down the throat of its exhaust. It’s super rich and loads up badly. It has a fresh motor all around from top to bottom. I…

BAFFLED Dear Mr. Know-It-All, I have a 2002 KX250. I love the bike, but recently it has started running very rich. It’s not losing transmission oil, so I know the crank seal is okay, and I’ve played with a million needles and pilot jets…

A FASHION RISK Dear Mr. Know-It-All, I have a fashion question for you. Do you know of a vented/warm-weather off-road pant that has a slimmer-than-normal knee area for those of us who don’t yet wear knee braces? The local shops have a…

SHE HAS A BLEEDER Dear Mr. Know-It-All, I recently changed the coolant on my 2001 KDX200. After pouring in the fresh coolant, I was skimming through my shop manual and realized the bike has an air bleeder on the cylinder head for the…

A 480-POUND POGO STICK Dear Mr. Know-It-All, I bought a 2015 KTM 1290 Super Adventure new, and I love everything about it except the suspension. The rear suspension has exceptionally light damping to the point where the bike just pogos up…

Dear Mr K I'm a two stroke guy who hasn't owned a two-stroke in years. Somewhere I gave in to peer pressure and got a used Suzuki RM-Z250. Unfortunately, I love it. It's unfortunate, because I have now ridden it for over 250 hours with…

TELL ME WHAT TO DO! Dear Mr. Know-It-All, I have a 2020 KTM 250XC TPI. Love the handling and suspension. Only “like” the motor performance. Stock, the motor is spluttery at partial throttle openings from low- to mid-range…

Dear Mr. Know-It-All, Last year I purchased a 2019 Beta 300RR, and while I am loving the bike, I recently had an issue with the oil injection. The oil light on the computer continues to stay on as if the oil level is too low, even after I…

Z 250 RING-DING PINGS Dear Mr. Know-It-All, I have a 2009 YZ250 that I race on both tracks and off-road. The bike runs extremely well, but I get some detonation when I put a load on the motor for long periods of time. My jetting is on the…

The KTM 300XC-W TPI isn't that different from a conventional two-stroke. We've been dealing with fuel-injection for over a decade now on four-strokes, and the rest of the bike offers no real technological differences from a bike in the late…

Dear Mr. Know-It-All, I have a 2017 Husqvarna FE350 that has around 1,200 miles on it. Upon the last ride, the bike started losing power and felt as if it were going to seize. This was at moderate-speed, fairly easy riding. I immediately…

Dear Mr. Know-It-All, I’m sure this topic has been beaten to death, but figured I’d ask anyhow. On a two-stroke bike, is there any harm, no matter how small, in allowing the carburetor to run dry? Thanks. Ken via…

Dear Mr. Know-It-All, My thermostat is leaking on my 2019 Beta 390RRS, and the bike is out of warranty. I’m not sure if I should replace the part or buy a hose kit to eliminate it altogether. Can you feed me your thoughts on my dilemma?…

SCRATCH THE ITCH Dear Mr. Know-It-All, I’d love to go riding this weekend. I have a new set of tires for my bike, but I’ve never changed my own tires. I attempted to do so, but only managed to get one side of the tire off and pull the…

Dear Mr. Know-It-All, I recently purchased a 2020 Husqvarna TE300i, but I didn’t receive the map switch that is supposed to come with the bike. I took the bike anyway, knowing my dealer would send me the part when it came in. My question…

GIVE ME A BRAKE Dear Mr. Know-It-All, I went to install new brake pads on my CRF450R, and when I put the new brake pads in, I couldn’t get my disc to go back into the caliper. Are these new brake pads the wrong ones or too thick? Is that…

Dear Mr. Know-It-All, I’m looking to make my tire changes at home easier, so I don’t always have to take them to a shop. I struggle holding the bead of the tire down in one place and end up chasing it around the rim while I’m installing a…
