DIRTY FUEL: MR. KNOW-IT-ALL

GREEN SPOOGE Dear Mr. Know-It-All, I’ve cleaned the carburetor and flushed the tank on my kid’s 2002 TT-R125L at least a dozen times, but I continue to get green debris in the jets. The bike had been sitting for years. Where is all this nonsense coming from? Josh via mrknowitall@hi-torque.com Josh, Josh, Josh, use that […]

BIKE STANDS VS. CENTER CASES: MR. KNOW-IT-ALL

ROCK THE CRADLE Dear Mr. Know-It-All, I have been an off-and-on subscriber to Dirt Bike Magazine since 1982. I have a new Suzuki DR-Z125L. Since that bike has no full cradle, it uses the engine case as part of the cradle, much like the old Honda XR80 or the new Yamaha TT-R125. Is it okay […]

WHY SO MANY THROTTLE CABLES? MR. KNOW-IT-ALL

Dear Mr. Know-It-All, Why do TPI bikes come with two throttle cables? I’m starting to see aftermarket kits converting them back to a single cable. My specific bike is a 2021 KTM 300XC-W TPI. Steve Baum via mrknowitall@hi-torque.com   It’s a safety system in case the spring on the throttle body fails. The second “push” […]

PEG ADJUSTMENT: MR. KNOW-IT-ALL

HIGH OR LOW? Dear Mr. Know-It-All, I am installing some Fastway Evolution pegs on my machine and am wondering which position to put the pegs in? The collar provided allows you to run them either in the stock position or a lower position. Have you had any experience with this? Marv Stuller via mrknowitall@hi-torque.com This […]

COOLANT LEAKAGE: MR. KNOW-IT-ALL

DRIPPAGE Dear Mr. Know-It-All, My 2002 CR250R is dripping coolant from this tiny hole under the water pump. What on earth is this hole, and how do I go about fixing this? Max Sheldon via mrknowitall@hi-torque.com That little orifice is a weep hole. It’s a sort of safety valve alerting you that your seals and […]

USED BIKE CHECKLIST: MR. KNOW-IT-ALL

CHECKLIST Dear Mr. Know-It-All, I’m going to look at a 2003 CR250R. The bike looks fairly clean, and the owner says the engine has never been rebuilt. What are some things I should look for to ensure I’m not buying into a mechanical nightmare? Herby Tonks via mrknowitall@hi-torque.com Great query, Mr. Tonks. Used two-strokes are […]

INJECTOR CARE: MR. KNOW-IT-ALL

Dear Mr. Know-It-All, I’m doing a top end on my 2021 KTM 300XCW and was wondering if I have to remove the injectors from the cylinder to slide the cylinder off? Ron Hector via mrknowitall@hi-torque.com Removal of the injectors is not necessary to remove the cylinder. Just unplug them, noting which plug goes to which […]

KTM STEERING-HEAD BEARNINGS: MR. KNOW-IT-ALL

STEERING CLEAR OF DRAMA Dear Mr. Know-It-All, I think I have a touch of play in my steering stem. I can hear it click when I’m just rocking back and forth. My bike is a 2018 KTM 450XC. It has fewer than 30 hours and was never abused. Do you think I’m in need of […]

TWO-STROKE WARM UP: MR. KNOW-IT-ALL

Dear Mr. Know-It-All, With the overload of “expert information” available for the proper warm-up technique for my 2020 KTM 300XC TPI, I wanted to go directly to the source of true knowledge to ensure I am doing it correctly. Currently, if the temperature is below 50 degrees, I pull the cold-start knob and allow it […]

BETA SHOCK BODY: MR. KNOW-IT-ALL

Dear Mr. Know-It-All, My 2021 Beta 250RR Race Edition’s rear shock literally came apart at the top of the shock body. I notice there is a seam where it broke. All of the oil had blown out of it in the process. What could have caused this? Harvey Monatt via mrknowitall@hi-torque.com This is an unusual […]

SUSPENSION TUNING: MR. KNOW-IT-ALL

TINY DANCER Dear Mr. Know-It-All, I have a ’20 KTM 300XC, and because of my size (240 pounds), I went to a much stiffer rear spring. My problem is that now it returns way too fast. I added rebound damping to slow it down, and all it seemed to do was wreck the feel in […]

SAVE THAT PIPE! MR. KNOW-IT-ALL

HITTING THE PIPE Dear Mr. Know-It-All, I’m an off-road guy and ride a Husky smoker. It’s a little weathered but hauls my carcass through the woods just fine. On a recent ride, it started running poorly, and when I finally stopped, I noticed a slight issue with the exhaust pipe. I must have caught it […]

SUPER HUNKY IS FINE AND DANDY: MR. KNOW-IT-ALL

Editor’s note: We got a voicemail from Rick “Super Hunky” Sieman concerning the fact that a number of his fans thought that he had passed away based on something they read in the August 2021 issue of Dirt Bike. It came from a reader’s question to “Mr. Know-It-All” lamenting all the old Dirt Bike times […]

DROP-OFF TECHNIQUE: MR KNOW-IT-ALL

Dear Mr. Know-It-All, Waterfalls and drops scare the daylights out of me. My kids ride down them like nothing, but I resort to bull-dogging most of the time. I have more confidence to ride up them rather than down. Any pointers for a washed-up geezer looking to keep up with his kids? “Old and slow” […]

NEGATIVE FORK PRESSURE: MR. KNOW-IT-ALL

Dear Mr. Know-It-All, I made an interesting mistake and require your insightful knowledge. As usual, the night before my ride, I load my bike into my truck. I use a fork brace and tie down the front end, then purge the air from the fork with my quick release. During last week’s moto ride, the […]

KDX CLUTCH WOES: MR. KNOW-IT-ALL

CHATTER Dear Mr. Know-It-All, I was riding my 2002 KDX 200R the other day, and upon pulling in the clutch, the bike started releasing a disturbing chattering noise. It was only when the clutch was being pulled in. It got progressively louder as I rode home. What on earth could be making this noise? Rich […]

THERMOSTAT, IN OR OUT? MR. KNOW-IT-ALL

SO COOL Dear Mr. Know-It-All, I recently picked up a 2019 KTM 300XC-W and had a question regarding the thermostat: run it or replace it with a straight-through hose kit? Vern Hatch via mrknowitall@hi-torque.com To be quite honest, Vern, we have had no issues with our long-term KTM TPI machines, which are running the thermostat. […]

SET-UP CHOICES: MR. KNOW-IT-ALL

Dear Mr. Know-It-All, I am an aging rider that is primarily riding off-road now on my 2004 YZ250 two-smoker. I had my suspension set up for motocross from Pro Circuit in my younger, more energetic days. I absolutely love the suspension, especially when I am on the gas through the rough stuff; it’s amazing. Now […]

KTM STAND MYSTERY: MR. KNOW-IT-ALL

Dear Mr. Know-It-All, I have a 2020 FC450. Husqvarna supplied a side stand that has four small clips on the front. I figured those clips were to attach the side stand to the bike while pushing it around, like hanging a T-stand on a footpeg; however, the clips don’t really fit anything obvious. So, what […]

KTM TPI BOG: MR. KNOW-IT-ALL

Dear Mr. Know-It-All, I’m having grief with my 2021 KTM 300XC. For no apparent reason, it started bogging and running a bit rough at all throttle openings. I’ve changed the inline fuel filter and cleaned the air filter. Not having a carb to clean, I don’t know where else to start. Please help! Lyle Durst […]
