  1. Hey! My name is Kyler. So recently my bike overheated like 3 times, then finally one day it quit on me. After draining the oil, it turns out there's shredded metal everywhere. So I tore it all down. Now I'm not sure whats the problem. So far all that I found is the little rectangular reed valve was missing 1 out of 2 screws, and around that area down there is where I found the most of the shredded metal. also, I'm not sure if its a problem but the actual shaft on the crank has the slightest bit of play. Mainly I just don't know what to replace so please help! I don't want to put it all back together and not replace the main prob. Thanks in advance!
  2. Hey. I just got a 94rmx with a complete rm makeover, but I don't have the tools to fix it yet so I've not ridden yet. I was wondering if anyone has tips about riding. And if anyone has some spare tool they could give a beginner. I'm pretty poor so could be some time till I get them myself. The pics my beaut
  3. I have a Honda crf50f and its been sitting for 6 years. I just got a new carburetor and it's now running, only 1 problem. It wont idle when the choke is on or up position, it will only idle if choke is in the down or off position. Any help on what it could be? Thanks.
  4. I got a question. I own a 2016 KX 85. It ran amazing after it first bought it used. I was riding one day with a bogging issue and about 35 minutes of riding I shut it off to take a break. Came back 20 minutes later and it would not start.I changed the spark plug, cleaned out the carb,checked the reeds,and tried hill starting it but nothing .When ever I try to hill start it I can hear it trying to crank and It starts for like half a second but then dies.There is spark coming from the plug though.I took the cylinder off and the piston and cylinder are &%$#@!ed.The piston rings were stuck in the grooves and I had to use pliers and a screwdriver to get it out.There was a ton of blow-by and the cylinder was scored.I bought a new piston already but how can I fix my cylinder.Im thinking of getting it repaired and replayed by either millennium,PowerSeal USA, or usnicom.This is my first time owning a 2 stroke.Any answers or tips.
  5. The RM125 seems to be in good condition. It has recently had a full engine rebuild. My CR85R is in good condition and I just rebuilt my top end and put a new rear shock and wheel assembly on it. Do you all think this would be a good trade and why or why not?
  6. In my last post, I shared details about how the two-stroke cylinder works, in today's post I want to provide an overview of how a performance two-stroke engine's exhaust system works. Adding a performance exhaust system can be a great way to increase power and/or alter the power delivery of an engine. I would also argue that optimizing a two-stroke engine’s exhaust system is equally as important as ensuring the cylinder’s ports are correctly designed for the given application. Not all exhaust systems are designed to do the same things, and much like cylinder port design, exhaust designs are intended to alter power in specific ways. Having a basic understanding of how an exhaust system works can go a long way when it comes to selecting the right exhaust pipe for your engine. Two-stroke exhaust design is complicated and there are many different variables that must be considered when designing a pipe. I don’t intend to go into all of them, but I will share a few of the most critical. Each time the exhaust port opens to release spent combustion gases, pressure pulses are created. Modern pipe designs harness this pulse energy and use it to help scavenge and fill the cylinder. The process starts when a positive pressure pulse is created once the exhaust port opens and combustion gases leave the cylinder. The positive pulse travels down the pipe until it reaches the diffuser, at which point part of the pulse is inverted and reflected back towards the cylinder as a negative wave. This negative wave is very beneficial in pulling spent exhaust gases out of the cylinder and fresh mixture up through the transfer ports. The remaining positive pulse continues on its journey towards the end of the pipe where it encounters the reflector. The reflector acts as the name implies and forces the positive pulse back towards the exhaust port. Once reflected back, the pulse remains positive and, if the pipe is designed correctly, will reach the exhaust port just as the piston is about to close off the port on the compression stroke at the desired RPM for maximum power. Any fresh mixture which has escaped out the cylinder will be forced back in by the positive pressure pulse. The tuned length of the pipe is dictated by the exhaust port timing, RPM of max power, and the speed of sound. Pulse length and amplitude are governed by the angles of the diffuser and reflector. Generally, steeper cone angles create pulses with more amplitude but shorter duration. Shallower angles generate pulses with less amplitude but longer duration. Given these variables, it is easy to see how a pipe could be tailored for specific applications. An engine converted for road racing may utilize a pipe designed for peak power which incorporates steep diffuser and reflector cone angles so that pulse amplitude is not sacrificed. This peak power would likely come at the expense of a narrowed range of power. An engine tailored for woods riding may feature a pipe with shallower cone angles, resulting in less pulse amplitude, but a broader spread of power. The last parameter I want to touch on is how the tailpipe, which is sometimes referred to as the stinger, influences the pipe. The tailpipe creates a flow restriction in the pipe which allows the pipe to have a certain amount of back pressure. Enlarge the tailpipe and the back pressure decreases, make it smaller and the back pressure increases. As back pressure increases or decreases, so does temperature and ultimately the speed of sound. As the speed of sound changes, so does the resonance RPM of the pipe. If the tailpipe is sized too small, cylinder scavenging will be inhibited. When this happens, the cylinder, fresh mixture, and piston will all be overheated. While engineers and tuners can estimate starting pipe dimensions and tuned lengths, a great deal of trial and error testing is usually still necessary to fine tune the exhaust pipe and optimize the design. Unless you intend on building your own exhausts, this work will have already been done for you. When selecting an exhaust system, you need to focus on how the exhaust alters the power curve. Exhaust systems are tailored to deliver more bottom end performance, top-end performance, or performance throughout the power curve. Selecting which system is right for you will depend on how you want your engine to perform. If you’ve chosen to modify your cylinder ports, installing an exhaust system that compliments the porting can be very beneficial. You might be wondering about slip-on mufflers. If you’ve followed along with my explanation of how exhaust pipes work, you’ll notice I made no mention of the muffler. While the muffler can have a small effect on performance, it is not the primary factor. Upgrading a muffler is a good way to reduce weight, but there won’t be a slip-on out there which significantly increases power, in the same way, a properly designed expansion chamber can. I hope you enjoyed this write-up on key features affecting the performance of two-stroke cylinders. As for Two Stroke Handbook news, we received our first printed proof of the book this week! Needless to say, we are inching closer and closer to an official release date. To stay updated on The Two Stroke Dirt Bike Engine Building Handbook we created an email sign up for our readers.

  7. I have a 2016 kx250f that is hard to start when the engine is cold, and when it does start you have to be wide open for the first 30 seconds or so and it sounds like its dying. and yet it still won't idle until its completely warmed up. it's not the valves because I had them reshimed at the end of the last riding sessions. I noticed it doing this after i replaced my grips, is it possible that I stretched a throttle cable? Or am I just completely wrong.

  13. Hello, I'm a beginner to dirtbikes and would like to know which would best suit me. Weight: 70kg Height: 5"10 Use of dirtbike: Just around a farm and will also be used to round up cattle and sheep. Won't be going fast at first but will increase speed as I get used to it. Budget: Doesn't really matter - I'll buy the one that suits me best. Thanks.
  14. Hi I'm looking at buying a 2010 CRF450R and wonder how often it would need to be rebuilt and have work done on it, if I use it for trail riding, I know it has about 110 hours on the engine and was rebuilt at 75, as I said I am only looking at it for trail riding, as it is a good buy for the money, I know the oil should be done every 5 hours and filter about 10, I'm just wondering about the hours for top and bottom end rebuild if i only trail ride it. ?
  15. Hey guys, Me and my team have built an Ice Racing Bike for the 2019 Numb Bum Ice Race. Due to the strange warm weather we've been having, and the lack of any info on the internet; does anyone know if the Ice Race is still on, or is there any other ice races in Alberta that we could attend so that we don't waste several thousand dollars in modifications.

    ohio Tires

    So, Im looking for a good rear tire to put on my KDX200. Ive thought about a hybrid tire but here in Ohio we have lots of mud and loose gravel. I was wondering what tire would be best for loose gravel filled hillclimbs but also works good in slimy type mud. but also works decent in hardpack. Main concern is the loose gravel hillclimbs, been thinking about a soft terrain tire as well such as a Metzeler MC360 Mid-Soft tire which has good reviews. anyone from Ohio have any good suggestions? not looking for a DOT tire though either.
  17. Jones Creek in Washington was where I first started riding in 1976. Today, its got a strong contingent of followers and an organization that does a great job of keeping the trail system alive and thriving. Recently, two more trail sections were added and there is more to come. I took some time and put this promo piece together for the organization. I hope you are able to take some time, watch the video, and come out to Jones Creek and ride. Your involvement is what helps keep these areas open!!! Enjoy!
  18. Hello, I have been looking for a new bike for awhile and have come down to either the TT-R110E or the TT-R125LE. I am 160 lbs. and 6 ft tall. Are either of these bikes good options? also is there any big pros or cons for any of them?
  19. Can I put regular car oil in a 2stroke transmission. My bike manual says to put 10w30 or 40 and I want to know if I can put regular car oil or do I have to put a special kind? My bike is a kdx80 bored out to and 85 if that's important.
  20. i have a 2004 crf 230f it had a NGK-DPR8Z plug and i have a new NGK-DPR8EA-9 plug will that work
