DR350 REPLACEMENT: MR. KNOW-IT-ALL

RANDOMLY BIZARRE Dear Mr. Know-It-All, Now I am ready for an all-new motorcycle. One I can buy and not fix it. I just want to ride it tuned to me—sag, tire pressure, fork oil, seat grip and handlebars, actual pull on the pipe and off,…

REMEMBER THE RMX! MR. KNOW-IT-ALL

YELLOW BOOST Dear Mr. Know-It-All, Hi, I’m looking to get some updates on the latest way to uncork the 2019 RMX450Z off-road bike. What is the latest way, parts, mods, to unleash the beast? You guys ran some tests and mods back in the…

BRAKE HEAT MYSTERY: MR. KNOW-IT-ALL

BRAKE TIME Dear Mr. Know-It-All, Should I beg for you to impart some of your great dirt bike knowledge? The way readers had to beg for a response from Rondo Talbot in the mid-’70s? I have a Husky, a KTM, and a new GasGas. When braking, I…

KTM HEAD INSTALL: MR. KNOW-IT-ALL

MY HEAD HURTS Dear Mr. Know-It-All, I just purchased an S3 head for my 2020 KTM 300XC and have a problem. I opened the kit, and I see the included head O-rings and crush washers, but I have one extra O-ring; it’s a smaller size. Where on…

TRIAL BY AIRBOX: MR. KNOW-IT-ALL

BOXING WITH AIR Dear Mr. Know-It-All, Can I delete the airbox on my old Aprilia (Rotax 277cc) two-stroke (trials bike) and just install a clamp-on K&N air filter to the back end of the carb? Some people say the box is there and can’t…

READ YOUR REEDS: MR. KNOW-IT-ALL

Dear Mr. Know-It-All, My new-to-me 2007 RM250 won’t run properly. It runs super rich and stalls on every downhill. I can’t keep the thing running for the life of me. It has fresh fuel and a clean, well-jetted carb. It is a new issue that…

BEAN OIL BLUES: MR. KNOW-IT-ALL

STUCK IN THE MIDDLE Dear Mr. Know-It-All, My exhaust valve in my 2017 300XC was absolutely stuck shut. Lacking snarl was an understatement. I was using Maxima Castor 927, partially because I liked the smell. You can’t use that oil. Darn…

HOT BRAKES: MR. KNOW-IT-ALL

Dear Mr. Know-It-All, At one point in time, I got myself some brake pads that had an extra piece that I assumed was some sort of thick heat-reducing pad. It went between the pad and piston. This was several years ago, and I have continued…

KLX300 CARB CLEAN: MR. KNOW-IT-ALL

Dear Mr. Know-It-All, My 2005 KLX300 has been running horribly, and I have nowhere else to turn. I figured the carb was just dirty and have cleaned it spotless. But, even still, the bike’s idle is inconsistent, and when you get on the gas…

POWERVALVE MESS: MR. KNOW-IT-ALL

Dear Mr. Know-It-All, My 2020 KTM 300XC has been making a horrible mess right around the power-valve cover. I’m not sure what kind of oil it is, but I’d expect that a new bike shouldn’t be leaking this bad. Please advise. Hoyt Oswald Via…

TRAIL CLOSED: MR KNOW IT ALL

CLOSED UP TIGHTER THAN A… Dear Mr. Know-It-All, I’m sick and tired of trail closures. Every time my buddies and I go to our local zones, there are always more trails fenced and closed each time. We ride respectfully, and most riders in…

RACE SAG SET UP: MR KNOW-IT-ALL

SAGGY Dear Mr. Know-It-All, Recommendations on rider shock sag are specified to the millimeter, yet my rider shock sag varies 5mm or more depending upon where I sit. Is shock sag measured when all the way up on the tank for cornering or…

MY 300 LACKS SNARL: MR-KNOW-IT-ALL

300 LACKS SNARL Dear Mr. Know-It-All, I purchased a 2020 KTM 300 XC TPI, and while I love the machine, it feels a bit docile when trying to get up on the pipe and revving the bike out. The bike has plenty of power, but lacks that snap and…

MR. KNOW-IT-ALL: FUEL QUERY

FUEL QUERY Dear Mr. Know-It-All, I can’t remember a time before your column was in Dirt Bike, and I have been a reader since before Super Hunky left, yet I have never before asked a question. What is the order of preference concerning…

MR. KNOW-IT-ALL: THE 300 MYSTERY

THE 300 MYSTERY Dear Mr. Know-It-All, Why are all the current large-displacement two-strokes 300cc? I see that 250s exist because of racing-class rules, but why don’t we have 350cc or 400cc two-stroke off-road bikes? The old Husky and…

DROOLING WR: MR. KNOW-IT-ALL

Dear Mr. Know-It-All, My 2008 WR250F has been sitting for over six months, and I had drained the fuel in the float bowl before I stored it. I’ve never had a problem with clogged jets, but this time when I turned on the fuel, gas was…

OLD LEAKY: MR. KNOW-IT-ALL

BIG-TIME LEAKER Dear Mr. Know-It-All, I recently performed a complete rebuild on my ’02 CR250R. While all turned out great, I have one stinking issue. A few hours after throwing the bike on a stand following the break-in ride, I began to…

FAT FRONT TIRES–MR. KNOW-IT-ALL

FATTY FRONTS Dear Mr. Know-It-All, I’m an off-road rider who is older and chunkier, but I love to ride in the desert. I have been seeing a lot of coverage on these “fatty” front tires. What do you think? Would one of them be a good choice…

CRAMPED BAR SPACE: MR. KNOW-IT-ALL

Dear Mr. Know-It-All, I recently bought a Beta 390 RR-S dual-sport bike. I love the bike but don’t care for the handlebars or the cramped riding position. The Beta top triple clamp has three holes for bar adjustment, plus the bar clamp…

OIL SPILL: MR. KNOW-IT-ALL

BETA OIL SPILL Dear Mr. Know-It-All, I have a 2020 Beta 300RR. I recently noticed after my last ride that there was a bit of oil seeping from behind my countershaft sprocket. I confirmed that it wasn’t excess chain lube and was indeed…
