had a 2009 yz450 project i picked up for 700 bucks. a whole new top end head, cams, piston. when finally get it back to running condition i switched my focus to the exterior components ie palstics, tires,wheels, ect. while i was waiting for parts i would occasionally go out and fire it up. after about a few weeks of this i went out and went to fire it up and it wouldn't start ...."hmmm thats weird". kick kick kick still no start. Valves? no wouldnt think so. "ill try to push start it". after about 20 minutes of frantically pushing it up and down my driveway i came to the conclusion that somthing clogged a jet. i losened the carb drain and nothing ...."hmm that weird ...why no gas" ...thats when it happend, my "aha" moment. i guess over the few weeks of just fireing it up in my garge had been enought to run the S.o.b out of gas.
God i felt like an idiot.

I was on the road on the East Coast traveling with the PJ1 Arenacross Series and had suffered a pretty big crash in the main event the week prior which folded my Renthals. So, I sat in the back of my van in the hotel parking lot with the propane heater on and switched out the bars. My bike was hardly dirty, but had a little dirt caked under the fenders and the number plate was peppered.

So - I decide to brave the cold and hit up a local outside carwash to spray down the bike so it looked as cherry as possible for the next show. I had run out of time on my wash meter so I stretched over to throw some more quarters in and when I did this the slack on the hose expired and pulled my bike over and slammed it on to the concrete - which smoked the brand new bars that never even saw the track.

Good times.

.At a big state race, father and I had a bit of miscommunication while adjusting my chain and WE forgot to tighten the axle nut. Nut fell off and the axle backed half way out. I thought I was losing my tranny and had a flat, but it was the wheel wobbling back and forth and the chain slipping on the sprockets. I still pinned it and got third, and was pretty freaked out once I got back to the pits and saw the axle! Lucky I didn't kill myself!
I did this....

I was adjusting my chain, when my then 5 year old son, came up asking to please start his bike for him. He had just gotten a new KTM 50 and was excited to get on the track. So I dropped what I was doing and took him out for a few laps on the peewee track to break it in.

Came back to the truck and threw my helmet on and proceeded to spin some laps. Totally brain farted on the chain adjustment/ axle nut. I got a couple laps in before the chain derailed and locked up the tire, on the biggest jump on the track !

I went straight over the bars and was lucky to only break my collarbone. Needless to say, my 5 year old was pretty upset that his few laps were all he got to ride... Laughing I felt really dumb !!

Years ago I sold a kid a 05 KX250 2t that I had. I assured him that even though it was raced the bike was top notch maintained and was good to go. Well, the kid had the bike for a month or so in which my phone rang one day. It was him on the other end screaming at me that I sold him a bike with a bad motor. He blew it up somehow. I asked him if he mixed the gas right, made sure it was ful of coolant, was he riding down thw road widw open, wct... He assured me he did NOTHING wrong and that I lied to him aboit the condition of the engine. So actually feeling bad for the kid I told him I'd take care of it offering to fix it at no cost.

So the next day after he drops it off at my shop I start the tear down process to see WTF happened. It took literally 4 bolts to find the problem. I removed the number plates and seat to find something I had never known possible... The air filter was in backwards. Yes, I know... How is that possible??? Well... it is. And when the kid took the bike to the sand dunes that weekend with his freshy cleaned air filter that wasn't sitting in there right imagine what happened? He had enough sand in the engine/carb/intake boot that I could have built a sand box for my kids!

Needless to say I called him up and said "you need to come over here right now." He showed up 20 minutes later to realize the valuable lesson on how to properly install an aor filter like it WAS installed before. He tried to argue with me that I put it in wrong but he knew his arguement was flawed when he looked at the other 3 bikes of mine at my shop. He also told me he had cleaned the filter before he went to the dunes.

I didn't fix the motor at "no cost" either. He wanted me to clean the bottom end as best I could and just throw a new piston/rings in it. My response, "nope, take it somewhere else." I was told that he took it to a dealership which cost him about 1300 to split cases and replace everything that was damaged. Haven't heard from him since he left my shop with his bike that day.

There are a few, but I'll give out this one as I was definitely embarrassed. Maybe not so embarrassed as just feeling like a moran.

Valdosta, Georgia...1988. I get the holeshot on my 1987 CR125 and am leading the race! Finally! No roost to deal with, just clear sailing. Man, my first lead! I like this!

About two laps in, I land off a jump and my handlebars collapse down and back. No more lead. In fact, DNF. It was extraordinarily difficult to steer with the crossbar hitting the fuel tank cap.

Why did this failure happen on the first time I ever led a moto (with a clean holeshot no less)? During the week, I had the bars off (this was so long ago the reason escapes me) and had put the right side bar clamp on backwards. That mistake was just enough to let them slip down in the speed of the race.

DOH!

A,friend brought his bike to me. Said it wasnt running right. I rode it and it was running way rich mid throttle sometimes, sometimes not.

I unscrewed the throttle slide and looked at the needle. I pushed on the needle and it slid into the slide without resistance. I looked up at him and asked if he had been "tuning" it. He said " a little". You probably figured it out by now but instead of assembling the needle clip between the slide and the spring plate, he reassebled the needle ON TOP of the spring plate so nothing was holding it in place. You open the throttle, it vibes off center and doesnt go back in the needle valve hole. Voila', instant rich.

When I was 7 years old in my first year of racing my Dad took me up to the track for a race day, we got there early so we could walk the track and get set up and everything. I get all my gear on and go to get on my bike to go out for practise, when my Dad abruptly realises he has forgotten to put the chain back on my KX60, because it was sat back at home on the workbench!

that's why i use WD-40 (and have used for years)


the alternate part of that story is that i've over-done it on the WD40 and my grips were more slippery than the inside of a van full of fat chicks on the way to the Ricky Martin concert

^^ "That sucks Doug, feel your pain!

Funny, the one time I did that race, I had a rear flat on the first lap.. what was funny is I really didn't feel it until I was coming onto the pavement on Main st. So, I pull over and check it there in front of everyone, yep, flat.. but I'm hearing the announcer dude commenting on me and it sounds like a movie.. "uh oh, is it flat? Yep sure is" cause he's talking about me..lol Very surreal.

Edit: Mine was Elsinore GP.. lol
Awesome, Outsider. Smile
That announcer was most likely no other then Tom White...
I also made the announcement speaker, but in a bad light. Tom White gave me a very hard time for stopping on the lip of the water jump one year and swan diving into the water....I was in 2nd place at the time, but what he didn't know was i was paying tribute to my best bro who shattered his foot on that jump the year before. I told him I would do it for him..i just had no idea I would be in 2nd place when it happend. damn it! lol

WD and safety wire, I'd run them without wire if I had to. WD lubes and softens the rubber so they stay put. They come off clean, no having to scrape off the glue. Jim Jannard and Dana Duke both used to carry around WD40 with an Oakley label on it before they were a billionaire and a ___________ respectively.

My last year on minis was rough on top ends. My kx 100 went through a handful of cylinders. so, when my bike bogged to a stop about 30 minutes in to a muddy hare scramble, I knew I seized it again.
After the race, and halfway home, my family and I are bs'ing around the trucks in the parking lot of the Mexican restaurant. I'm looking over my once again disappointing bike. Then I see it......The spark plug is hanging by the plug wire. I obviously didn't get it tight when I rebuilt the bike. I don't remember if I fessed to it or not, but my heart sank.

After a year of racing, I decided to go to the Red Bull last man standing. I went through my yz250 and prepped it. You don't spare any expense when you're prepping a bike for the "world's toughest race". I spent bookoo bucks gettin this thing fresh, no details overlooked.
I go through qualifying, get my bib, and get ready to go racing. The bike was prime. My taller gearing was killing me on the crazy fast qualifier course, but I knew everything would be good once we hit the gnarly stuff. Race morning I'm sitting on the starting line, full Red Bull spectacle......film crews, helicopters, and the big starting cannon. I'm psyching myself up, warming up the bike and my hands on a chilly Texas morning. I've got my hand behind the silencer, when all of a sudden, I hear a "pop" and feel something. I check out my hand. My palm looks like I just rubbed all the glitter off a local stripper. I was holding the fragmented remains of my new piston.
My new crank was backordered so I put the bike together, figuring the crank was more than fine after a year of racing. I was just trying to cover my bases before the big race. Apparently I was wrong. Lower end locked up and sent everything wonky.
That was a pretty shitty walk back to the truck. Pushing my bike off the line in front of all those people suuuucked.

I bet wd-40 smells better then the inside of that van.

I was racing my 95 YZ250 one weekend on Saturday and Sunday at Baja here in d14and it was muddy as hell on Saturday. I go home and proceed to wash the hell out of my bike and go back to the track the next day. First lap of practice I hit the whoop section they had at the time with some gusto and got a few in and needed to chop the throttle but when I did I could feel that the cable wasn't going anywhere and in that fraction of a second I realized that my slide wasn't returning to the bottom of the carb body and I ejected...lol. I get the bike back to the pits and take the carb apart and discover a gooey residue mixture of filter oil and water. I didn't take the filter out and put in the cover when I washed it and forgot to at least put a new filter in for Sunday.

Yes, I believe it was the 05' race where Tom White called me out. I was told he announced the race for years.

I recently picked up first 4 stroke and am realizing they may vibrate more than 2 strokes! First time out the bolt that feeds through the holes in the front brake pads to hold them on backed out. Pads fell out on the track. Second time out, while sitting in the pits looking at the bike, I realized the rear axle bolt was finger loose and halfway off. That would not have been pretty!Loctite everything I guess.

Brand new 05 YZ250 (the one to the left) probably 3rd time riding it went to a race...wouldn't start, missed practice, kicked and kicked changed plugs swapped ignition boxes towed it up and down the pits with a quad....nothing. I was so mad. Got home and it had a rag in the air box. Right where I left it. Oldest stupid move in the book and I did it.

When I was a kid I was bad about tightening my chain and cleaning the air filter. I finally broke a hub that took me weeks to pay for...soon as it was running again it blew up from the dirty air filter. I learned the importance of maintenance the hard way

Back in 03 I did a top end replacement on my 03 cr125, everything went fine putting it back together. During assembly, I had moved my pail of radiator coolant aside, I mean way aside. After finishing, I started the bike up and let it warm up for a minute or 2 than started blipping the throttle, things started to heat up fast, then I remembered that I forgot to put the coolant back into the radiator. After I cussed myself out, I filled the radiator and fired her up. Luckily there was no damage Unsure
