  1. Same here. I have a YZ450F but it's heavy and getting harder to ride and start in the technical stuff. It needs a Rekluse clutch.
  2. Nice! The pictures you posted though didn't show the clamps up close.
  3. I bought one of those 10 years ago, thinking it was made in USA, kind of a surprise to see "Milwaukee" next to "Made in China." Well at least it's well-made and still running.
  4. That sounds like a good idea. But one of the reasons for the pivoting bar risers is on the CRF230, the bars are too far back. So you need a riser that moves the bar forward and up.
  5. Very funny but true. If I'd hit something I would remember it. We were riding some very technical terrain with up to 24" ledges. I crashed one other time earlier that day climbing a steep rocky hill and remember exactly what happened. It was completely flat where I crashed the second time and I was very focused. And no I wasn't drinking, but I did stay in a Holiday Inn Express.
  6. Think about what you're saying. If your handlebars come off while accelerating, do you know how long your bike will continue on a straight line? When you turn, how much do you have to tweak the handlebars to go a different direction? It's miniscule. Have you ever hit a hidden branch with your handlebar and landed at the bottom of a draw faster than you can say wth? Or been riding on snow or frozen dirt and suddenly hit a patch of pure ice? If not, then you need to come out and ride western Colorado or eastern Utah instead of that sissy stuff. The day I fell, we were riding some very technical terrain with up to 24" ledges. It was flat where I crashed, and you're right, I would remember if I hit something. No, I was talking about the Chinese knockoff.
  7. Likewise with a lot of Chinese stuff. Shopping for cheap lithium batteries, there are so many vendors competing with each other, many vendors will out and out lie about the watt hour rating to make it appear they have a better product, when really they're all the same. Most of these unethical vendors are located in California. I bought a backup battery last winter that was rated something like 10x the actual storage capacity. Part of my personal product testing. There is some good quality stuff coming from China but it's the exception not the rule. Some BMW motorcycle engines are now assembled there, but I'm sure the company has a lot of oversight in the process.
  8. I did look and saw that before I bought. Even though the ad said CNC and T6 6061, it looked cast to me. So I spent some time researching the difference between cast and CNC. I only found one article that explained that even CNC milled comes from something that started out cast. What it really comes down to is the quality of the alloy, and is it forged.
  9. You're absolutely right. The eBay vendor where I bought the Chinese junk says they're made of T6 6061 alloy that is CNC milled, which is an obvious outright lie. As for the real 6061 T6, I'm pretty sure that's what the original triple clamps are made of, which the factory bar clamp bolts to. So the Rox risers should be as durable as the factory setup.
  10. I did my homework before buying these. There were some nice CNC ones made in USA for around $45-70 and cheap Chinese knockoffs for $17-30. I only found one review that said to stay away from the Chinese knockoffs but it didn't say why. Looking at the design, I assumed that maybe they would loosen on the pivot point before they would break, so decided to try the Chinese knockoffs from eBay, and mounted them on my CRF230. Yesterday I finally had a chance to try them out. Performance-wise they worked great. Having the handlebars moved 1" forward and 1" up really made a huge difference in riding this bike, as did a new rear tire, 1" fork spring preload spacers, repairing a leaky fork seal and replacing the fork oil with 15W. About 2-1/2 hours into my ride, I was going pretty fast on a straight smooth stretch, and all of a sudden I crashed very hard, my helmet slamming to the ground (with my head in it) and sliding for about 10-15 feet and banged my upper left rib cage, forearms, right knee and shoulder in spite of wearing all the protective gear. It really knocked the wind out of me and knocked the goggles off my helmet. I laid there dazed for a few moments wondering what happened before slowly moving around and feeling my body to see if I was injured. Other than a few cuts and scrapes I was okay. I looked over at my bike and noticed the handlebars had somehow turned and were parallel to the bike. In my confused state I was thinking of how bicycle handlebars can rotate on the stem, wondering how that happened on a motorcycle and how I hit hard enough to bend them. I finally got up and looked around to see what I had hit and was surprised to see it was relatively smooth and there were absolutely no obstacles. I noticed the handlebars were not rotated but had snapped cleanly off at the bar risers, right where they clamp into the triple clamp. That's when it dawned on me that I had not hit anything, the handlebars just snapped off at the risers; that's what caused the crash, and was not the result of it. Fortunately I had my tools and was able to remove the risers and replace the bars in the original clamps and ride out the 25 miles back to the trail head. Lesson learned. So here are some photos. I wish to warn anyone else before buying these, stay with the US made CNC ones like Rox (sold on here) and other brands. Some Chinese stuff is okay (like the amazing CNC milled ASV-type levers sold on eBay that you see on my bike, they worked great), but don't risk your life with these. I feel very lucky not to be in the hospital today. I should add that I sent a request to the Chinese eBay vendor that sold me these for $17 and asked if he would like to not only refund my money, but pay for a new helmet since mine is damaged pretty badly. This morning he offered me a $5 refund which I rejected. Ha! We'll see where that goes. I've already ponied up the extra money and ordered the Made in USA risers. This is the worst I've ever banged up a helmet. Can you imagine if I wasn't wearing one? You can see from the separation this is very cheap aluminum casting, with low quality alloy. Here is where I crashed and you can see I've already replaced the bars with the original clamps Here is the actual picture from the eBay ad where I purchased these killer bar risers.
  11. Zero. Nada. Nil. What's your point? Should have been dead way before I started MX riding.
  12. You're all wrong. It is "MOTO-CROSS" not "MOTOR-CROSS." From wikipedia: "Though known as scrambles racing in the United Kingdom, the sport grew in popularity and the competitions became known internationally as "motocross racing", by combining the French word for motorcycle, motocyclette, or moto for short, into a portmanteau with 'cross country'." https://en.wikipedia.org/wiki/Motocross So because it's from France and U.K. it's cool (not a redneck sport) and you can tell all your lib-tard friends to chill and stop their bitchin.
  13. Sorry Aymen, I must have been speed reading. It wouldn't hurt to double-check the float, altho I know it is a PITA getting the carb out. I've had the float bend on the trail and had to remove and readjust in 100 degree + weather while my buddies laid in the shade taking a nap. Also, I've thought I had the float adjusted perfectly but it still leaked. You can test that with the carb out of the bike.
  14. I can't believe no one has mentioned that you have to adjust the float, not just inspect it. Sure the needle and seat look fine. That is rarely the issue. The VERY COMMON issue with carburetor floats is the tab that positions the float gets bent and does not shut off the fuel flow like it should. Here are some guides to get you started:
  15. I would try the Chinese exhaust, although I doubt there is that much power improvement over an uncorked "straight through" OEM exhaust or even FMF etc. China is where Japan was in the 1970s. In the 60s "made in Japan" was synonymous with junk. By the 80s they were the best. I've gotten some Chinese stuff that was excellent, and some that was junk. I love the design on this exhaust system.
