    Just bought a 02 and it won't start

    Sounds like the timing is off

    2009 CRF450R Top End Torque Specs

    Welp, he thought he had a blown head gasket because it was puking coolant out the over flow. He tried a different cap and that did not cure it. He brought the bike over and showed me what was happening. He had the over flow tube connected to the barb for the crossover...5 minute fix. Still needs a top end though.
  4. I am helping out a friend and putting a new piston in his 2009 450R. The problem is that I know my 2002 engine and have a service manual for that generation but I do not have anything for this bike. I was hoping someone could help me out and give me the relevant torque specs. Also, his rebuild kit came with some blue rubber nub looking deals, I suppose I will figure out what those are when I pull it apart, any clues? Any other tips or weird things on this engine?
  5. Look into the Rekluse clutch. I have never ridden with one but I hear its awesome.
  6. like he said, auto clutch and a left hand brake is the way to go. you could do this with off the shelf parts fairly quickly and easily. it would honestly probably give you more control over the bike than the stock configuration.

    Building a shock dyno

    We do have data aquisition. Which admittedly is the aspect about which I know the least ammount. I am aware of how the current shock dynos work. I have looked at several and almost built one but cost was the number one factor this this design. We will be using a load cell and a LVT to measure force and velocity. As long as these are measured and sampled at the same time, what does it matter how the shock is cycled? When the shaft is moving at 5 inches a second it should behave the same no matter how it accelerated to that speed (baring any cavitation or any funky business like that) Also, since our shock is linear in nature, once the high speed dampening takes over (at about 2-3 inches a second for our shock) you can extrapolate out to what ever speed you wish. Look at this graph produced by a $8,500 dyno for our shock If we can produce something close to that, I will be happy. For this dyno, I am not after replicating real world forces the shock will see. A much better way to do that is onboard vehicle DAQ. This dyno has a different use.

    Building a shock dyno

    I havent been updating this thread. But I have been working on this project. I was able to slap it together tonight and give it a little test. http://www.youtube.com/watch?v=1jY_qBRZfCQ
  9. ~80-95% less depending on what bulbs you are talking about

    White smoke after installing FMF

    the smoke is likely from the new pipe. mine did the same thing and will go away shortly. its white smoke coming out the pipe after you shut it off almost like something is burning inside right? you also need to rejet like others have said.

    Building a shock dyno

    I see the dyno being used mainly just to verify that the shocks are balanced and don't require a rebuild, not necessarily shooting for the functionality of a $5K+ machine. That is if it gets used at all. I do not see a huge safety issue here. I am not sure on cost yet, it depends on what my team is willing to spend, if we can fund raise any, if we can get any materials donated, etc. I am unsure which model shock it is exactly.
  12. place a weight on it and measure the change in length.
  13. I am designing a shock dyno for my senior project. Ideally, the dyno is going to be used for the BAJA SAE and Formula SAE teams at school. The Baja team (which I am the VP of) runs Fox Float ATV shocks while the FSAE team (I was drivetrain lead last year) runs mountain bike shocks. I just have some questions for someone who has experience with shock dynos. I am currently trying to set up a meeting with an engineer at Bilstein and/or Fox since my location in San Diego makes that relatively easy but I am not getting my hopes up. I also have to pay for this project all myself so I can't get too crazy with it unless I get some sponsorship money. As of right now, I am thinking of a simple design like this http://www.shockdyno.com/ If anyone knows what kind of timer that dyno uses I would really appreciate it. I need a way for this thing to automatically start timing when motion starts and stop timing when motion stops. I would rather do a design based off the fancier machines using an electric motor and a load cell but that increases the complexity 10 fold and also drives the cost way up, but it would be cool and could be done. Plus I would get a chance to learn about electric motor control and a better understanding of computer programming. Something like this would be really cool and is in the realm of possibility but cost and complexity (time) are limiting factors. https://www.youtube.com/watch?v=Sz-vaZzTB1g
