You're on the track and your throttle sticks WFO just before a jump (what do you do?)

Happened to me in 1992 on the practice track behind my house, first ride coming back after a broken foot.  Throttle stuck and I launched off a jump, tossed it away mid-air, landed and broke my right tib/fib.  

 

That cost me my trip to Loretta's that year as I got the cast off the Friday before and was in no condition to race.

Lack of a clutch caused one hard wreck on my Alta. Needless to say I bought the strongest left hand rear brake I know of for my Stark which retains the foot brake.

A few months ago at one of our hare scrambles there was a fast straight away in a field to a sharp left turn and someone's throttle got stuck supposedly and hit three people and two were life flighted out but ended up being mostly okay from what I heard. 

Something to keep in mind while spectating especially off-road races where its a free for all don't stand at the end of a straight away.

Had that happen once luckily it wasn't on the track. With this 1980 RM125 riding down the long gravel drive way we had. After a 5th gear wide open rip it stuck. 

Took me a couple seconds to figure it out. Pulled in the clutch slammed on the brakes. Skidded about 60 feet to a stop at the base of two big fir tree's. 

Turned out the cable broke part way and the frayed ends got stuck. Bound up in the throttle cable housing.

Pull the clutch.

Back in my school boy days i had the throttle body cover come loose in the first turn of a moto on my 125.

it was a mikuni TMX carb with 3 bolts that hold the cover and they hade come loose.

I rode the whole 20 + 2 moto with a full open throttle just using the clutch in the air and turns.

 

On a SX track it’s another thing but a pro rider should be able to pull in the clutch to prevent a loop-out.

 

There is legitimately no chance you did an entire moto stuck at WOT. 
 

Also, what amateur race, not being an amateur national, runs 20+2 in schoolboy?

Talk about a nightmare scenario!

What could/would you do to not end up going home in an ambulance?

You could pull the clutch but would you endo? Brake tapping drops the front end quickly so maybe just pulling the clutch and no back brake you could save it?

I had a throttle stick wide open when I was 15 years old racing on the Shadow Glen Track at Indian Dunes and my bike ended up hanging upside down on a chain link fence. when it happened I had no idea what to do.

For sure a rare event but having a plan just in case can't hurt

 

Had it happen once.  Keihin D slide carbs in the early 90s had an issue where a piece in the slide would break, and it could keep the slide from returning.  Happened to me in the LA coliseum in practice at a MTGP (quad) event.  The way these failed, you wouldn't know the throttle was stuck until you let off.  In my case two small doubles almost became a quad, I crashed hard, and was really sore but able to race that night.

Try not to die.  The biggest factor is the second or so it takes you to figure out it is stuck, then reacting to it!

Scrub it the best I can and prepare for a hard landing!

The only time I can remember having a throttle stick was due to a crash. The bike landed on the throttle and was WFO on the ground. I thought it was just stuck in the mud, so I picked up the bike in a hurry. Actually, the throttle tube was broken and had gotten wedged wide open. When I sat the bike upright on its wheels, it was in 3rd gear with the rear wheel spinning at 72,000 RPM or something akin to that. The bike wheelied right out of my hands, looped out, and thrashed around in the underbrush like a mountain lion with hot sauce on its eyelids.

I’ve had two big ones… first did a Superman and tried to land it but pulled my arm out of the socket followed by many front flips 

second same track my stupidly fast ktm 125 02 decided to stick open through a super fast jump section..threw the bike ended up in the corner having a nap for a while

found out on the forum ktms used to do that

ive never been reliant on the clutch so I never thought of it off a jump usually too late by the time you realise.. maintain your throttle haha

Some of you know my story, some don't. My throttle jamming open is what ultimately put me in a chair for life. I was racing arenacross in 2001 (I was 12 yrs old) in 85 12-13 & supermini class. Raced the same place the 2 years prior and did great so I loved the track and the vibe of being in a stadium.  

I had a bad start, working my way through the pack. Came up on that "Dunlop catapult" jump they called it, I had jumped it a hundred times before so I was very comfortable and confident doing it. The kid in front of me had the inside so I decided to rail the outside to pass him, I'd be able to make the jump and he wouldn't so I'd give myself some room after the pass. He tried to cross over to block me so I gave it some extra power to miss him but it was too much and I over-cleared the landing and pancaked it pretty hard. I had a works PC bike as a support rider so the suspension was the best you could get. I landed with the throttle WFO to cushion the landing best I could and without knowing it the throttle body had cracked and jammed.  Heading to the next turn I kept it wide open but when I tried to shut it down it wouldn't move.

 The turn ahead was a big berm with a vinyl net on top to keep riders from going over to the other side where the first turn was. After that was a big cement wall covered with a black tarp where seats were taken out for the extra space. Now in hindsight I should have grabbed the clutch and slammed the brakes but shit happens SO fast and not only the panic from realizing your throttle is jammed wide open but also I was a little shook from the hard landing so I went full speed up to the turn. The net caught my bike and buckled, absolutely no damage to the bike. I was shot over the top like a slingshot, flipped upside down through the air and slammed into the cement wall about 10-15 ft high then fell to the ground, like a bug on a windshield. I hit the wall upside down sort of on my right side and rolling to my back. Broke 6 vertebra, arm, shoulder, ribs, sternum, concussion. 

I've only had one other time ever before where my throttle stuck. It was at the top of the hill at Hangtown on a long straight but I had enough time then to pull the clutch and brakes, no crash. Back in the pits my Dad pulled the throttle body and had a tiny crack in it. Crazy how a couple years later I'd have the same issue but it was my mistake from over-clearing the jump. No idea why it was cracked that first time though.   

 Watching what happened to Chase made my stomach churn because I had been there before and when he was laying on the ground it brought back that memory. This sport is brutal and shit happens but luckily he'll be fine and will ride again. I can't help but imagine he might have some demons in his head for a little while though going up jumps. This sport is such a massive mental game but the only way to get over it is to get out there and get that confidence back. If it didn't put me in a chair I can guarantee you I'd be right back out there as soon as I healed up racing again.

Happened to me back in 2003 at the old El Cajon track approaching the big double in the middle... My weight was to the back of the bike due to me not expecting to be WFO. No chance of saving it so I chucked the bike, rag dolled upon landing, jacked my back up but I walked away.

Last thing I would've been thinking was to pull in the clutch, it was just sheer terror. Grinning

I can answer this from experience....

Crash into the side of the burger van, parked just off the track.

Luckily it was on a 125, it was uphill and I was still a kid 😂

As an adult, the only time I can remember  was whiskey throttle scenario not a true stuck throttle this time, and I just pulled the clutch.

Also, what amateur race, not being an amateur national, runs 20+2 in schoolboy?

In Sweden all youth classes 85 and 125cc run 15 or 20 + 2 motos at all the local races/series.

Hell, the whole europe run the same.

And yes, i ran the whole moto like that. I passed my dad at the mechanics area wide open with my right arm in the air the first lap.

I don’t see why it’s that big of a deal? Just pull in the clutch when you should have let off the throttle otherwise.

The bike sucked in a fair ammount of dust so for the second moto i had no compression.

Stuck throttle in 2001. Landed on the gas from a down hill double. When I went to chop the throttle going up the small single going into a left hand turn….. it didn’t. I jumped off the back, broke my left tibial plateau and the navicular in my right foot.  Luckily, the ambulance crew saw the damage, and got me the Hartford Hospital who had amazing surgeons.  But a very painful long ride.

I did the exact same thing in 2015 and ended up just like Chase.  My Asterisk knee braces were destroyed, but not my knees.  I had not seated the air filter correctly and there was sand (MMX Marysville) in the carb.  Took 6 months to get back on the bike.

I wonder what AJ Cat or MX Factory would say about this. 

4/23/2024 10:44am Edited Date/Time 4/23/2024 10:47am

One of my friends had his throttle stick on his 300 at day in the dirt a few years ago. It’s where you came back onto the MX track, so you drop about 10’ into the track and then have a huge straight away running to a big tabletop that you ran opposite, so you’re going up a super tame incline. He dropped into the track, grabbed 3rd gear and wound it out and the damn thing just kept screaming. By the time he realized what was going on he was able to pull in the clutch right as he was going off the descend of the jump. He wadded pretty bad and it’s really messed with him since. He maybe rides 10x a year now and no where near the pace/intensity he did before.

If his throttle stuck open then why wasn’t the bike going when it hit the ground?

Easier said than done to think fast in that scenario lol

The tibial plateau is a very nasty injury, and so rare usually.

Rear brake because the clutch can be hard to get to

Why would i lie about that just because you can’t wrap your head around the fact that there is people in this world that can do things you can’t?.
