  1. I’m 14 and my rm85 smokes so much and my power valve is making a lot of rattling noise. I took off the cover and it had a lot of black residue and there was a puddle of it under my power valves and so I cleaned it with contact cleaner and took out the power valves and looked at them and they had little scores on the top and some (but not too much) carbon on the top and bottom sides. So I cleaned them off and put some oil on them and popped them back in and I started it with the cover off and they were barely doing anything except for rattle I got along with EVERYTHING else. The previous owner honed it out and it is nikasil so idk if that has anything to to with it smoking of not but I haven’t had the chance to go get it replated because I don’t have $250. I ran it all sorts of ratios and the manual said to run it 30:1 but when I run it 50:1 it still smokes a lot and way too much and I use motorx oil. I’ll add a video on YouTube and copy and paste the link here.
  2. So I'm one of the local tracks recently waiting for racing to begin. I'm trying to read up on proposed improvements to next years motocross bikes and my Wife is going on about something or another but I'm not quite sure what it was. I know I heard the words foreclosure and Sheriff and something about being forcibly removed, but I was distracted. Pulling into a nearby spot is an unbelievable race rig with a matching trailer in tow. Although I am at the track every week, I have not seen this particular cashhole before. I ponder the possibility that this is a current or retired famous pro rider traveling the country in secret to try out new tracks and surprise adoring fans. Is it Dungy? Charmichael? Villopoto? McGrath? After the air brake blew out the ear drums of some little kids playing in the sand nearby, out comes a man and woman with Factory KTM pit gear on. "Testing 1-2-3" one says into a headset with a microphone. Thumbs up from the other. Communication;Check. Little kids running around screaming holding their ears;Check. With the dramatic entrance complete, slide outs extended, and headsets working, its time to roll out the equipment. Many side stretched motocross eyes have fallen upon the developing pit site who's stewards are moving with the sense of purpose and authority of a Federal Hazmat team. Up go's the KTM tent and it looks like a factory mechanic is checking the spark plug gap on the power washer. Weird. These guys are serious. It looks like about a dozen people have gone into the trailer. Its starting to resemble one of those clown cars. I can hear the sound of an air compressor, tool chest draws shutting. As the bike rolls out, I feel the collective air come out of a hundred people. Its a 50cc KTM pisser! WTF! My testicles shrivel into a raisin in protest. Well OK, after a few wrinkles straightened, I decide to go with optimism, after all, a super talented mini rider is fun to watch. Maybe I can pick some brains and take in some knowledge for my own kids benefit. Moments before the first moto, I first lay my eyes on the center of all this commotion. I'll call him little Mikey Moto, 9 or 10 years old. As he surveys his kingdom and the commoners around the track, he looks like the type of kid who eats boogers and tortures animals for fun. With an air of indifference, he walks up to his mount which has already been warmed up for him by a KTM clad person who seemed unwilling to make eye contact with him. If this was his Father, he was not admitting to it. I was half expecting the kid to throw a sack of coins at the poor soul like they would in medieval times. There seemed to be some sort of problem with the clutch. After twice stalling the engine, the bike was flung on the ground and the kid started to kick dirt on it. With an obvious bike set up malfunction, the KTM team bound into action. A twist here and a wiggle there, and the problem seemed to be identified. A man who seemed to be in charge would continually stare at something on the bike while bringing his eyes closer, then further away. There seemed to be a consensus that whatever the problem, it was able to be fixed by staring at at intensely. Little Mikey Moto had calmed down and kept himself busy by scratching his name into the side of the RV with a rock while his KTM clad Mother said "Oh Don't" and walked away, presumably to make another highball. A quick wipe down of the bike and Mikey was off to the starting gate, this time with the help of a push so he could get used to the optical clutch adjustment. The intensity at the gate was palpable. Little Mikey stared down his opponents like ants he was getting ready to burn with a magnifying glass. I stood taking notes, not wanting to miss out on the chance to learn the highly sought after upper crust dirt techniques. He throttled that little 50 just like the pros do. It's go time and the starting gate sounds like a hive of angry killer bees flying at full speed ready to kill or be killed. The gate drops and all eyes are on the holeshot!! I'm not talking about the bikes, I'm referring to the parents running full speed from the gate, like a pack of wild hyenas, to the preferred viewing area, with Iphones and Ipads recording 15 inches from their face, while plowing down anything in their path. The winner of the 50cc parent holeshot went to a Tile Mechanic named Joe who was wearing a t shirt with his kids name and race number. He was able to win the holeshot while carrying a push broom, foot blocks, a camcorder, and an umbrella while simultaneously screaming GOOOOOOOOOOO!!!!!!!!!!!!! By the time he stopped, his temples had pounding veins protruding and bulging eyes that resembled a bulls immediately after castration. He almost ended up in second, but the other guy had to stop and take a couple of Nitroglycerin pills. God Bless them!! Anyway back to Mikey. After the standard 20 bike pile up in the first corner, I search the pack for our newest Factory KTM Phenom. I don't see him. I follow what looks likes long s in the track from the starting gate into a bale of hay, where Mikey is laying on the ground getting attended to by Medics. After some fuss, little Mikey finally got up to a rousing applause the likes of which I have not heard since 3am during Big & Tall night at the local strip club. Anyway, after an animated discussion with Mom, Mikey stomped off and away down the driveway to the track. The KTM crew was huddled around the bike in intense discussions about what went wrong and what changes could be made. I believe the final determination was that the addition of anodized valve stem caps was what threw off Mikeys balance. I made notes about this so that I would not make the same mistake. I decided to try to help the situation and asked the Mom if she wanted me to go after Mikey and bring him back. She replied that he had simply gone home. Seeing that I was puzzled she explained they only lived two houses down from the track.
  3. I went with a friend of mine to look at and ultimately purchase a used 2007 CRF50 last week. While originally checking it out, I noticed that the idle would hang a bit after letting off the throttle (basically after the throttle is open and then closed, the engine will stay at a high RPM and not settle back down to normal idle for different amounts of times - sometimes just a few moments, other times up to 8-10 seconds), I figured it would be something minor like the throttle cable or gummed up carb, so I told him it was good and he bought it. I took it to my house to go over it and see if I could figure the issue out, but have been unsuccessful. I changed the oil, spark plug and filter (the filter and interior of the air box were pretty sopping wet with oil when I first opened it up). I also took the carb apart and rebuilt it fully with an all balls kit. None of this changed the mannerisms that I described above. I checked the cable and it seems fine, I also could actually see the slide opening and closing with the throttle tube in the carb. I've been told that this issue might be due to an air leak after the carb. I sprayed carb cleaner all over the intake in an attempt to find a leak, but I wasn't sure if I did. There were a few times that I sprayed and the idle hopped up, other times it didn't. I did set the fuel/air screw and idle screw at the factory setting after the rebuild as well. I feel bad because I went to look at the bike with my buddy and told him it was good, and now I can't get it straightened out for him. Any help or suggestions would be much appreciated. I can give a better description or put a video up of it if that would help. Thanks!
  4. Hey all. My eldest son has just got keen into moto. He is 6 has had a ttr50 for the past 12 months or so. Recently my brother has a left a used KTM50 mini at our place and he is mad keen on it. I want to buy one rather than use this one because if he rides this one and wrecks it or really likes it ill have to replace or buy one anyhow. My questions are in the mini range what are the signifigant model changes and years. Mini, mini adventurer, air cooled, water cooled, disc brakes, shockies etc...? Basically im just after a timeline on the 50 mini. Is there a throttle stop screw arrangement available like on the ttr or crf? Also when i do get one for him, is there a good source for parts and service manuals and? Im thinking at this stage i might try and get an older air cooled one which is hopefully a bit tamer and not as expensive to buy or repair. Thanks Heaps.
  5. Hey everyone, I have a small Azusa Minibike kit that I put a Harbor Freight Predator 212cc engine on and I'm having some issues with the engine. I had taken some components off it after hearing some strange noises now the rip cord locks up solid when you go to pull it to start the engine. It is not seized up because when the spark plug is removed it can turn 100% freely. You literally lift the bike up when trying to pull on it, it's completely locked up. Any ideas or has anyone had this/ a similar issue? Let me know, Kind Regards GriffDog
