    Slightly broken clutch assymbly

    The bike had only about 12 hours of "wife" riding on it when I changed the flywheel weight out. With in 2 more hours is when the part let loose. Other then that there was no other work done that would have impacted the clutch or related parts. Oh by the way, it has been fixed <G>.

    The case had parts of it twisted down that scraped the outside of the case. The pieces are not there any more in these pictures because after the ride, every one in camp kept playing with the pieces and finished tearing them off. The spring / bolt / boss was no longer around by the time we found this issue. We found this had happened because on the ride home, we stopped for a break and my wife noticed oil all over her boot. I just think that since there is not a lot of metal right in the area that broke it either broke from a bad spot in the metal or I could see if that one bolt was over tightened it could have weakened that area. Since this happened on the first "real" ride after the FWW was installed, I still think that had something to do with it. In any case, I figured I'd show the handy work off.<G> DW

    I guess I should have posted these first as well as the other pictures<G>. http://helibuf.com/dirt/crf150r/Clutch%201.jpg http://helibuf.com/dirt/crf150r/Clutch%202.jpg This did not happen because of some thing loose. I took this part to a metallurgist we use for work and there is a small spot where the metal had a bad spot in it. This allowed the "stem" to break off and rattle around with the spring / bolt inside the case till it finally came through the rather large hole it created<G>. Where this broke there is only 1/8" or less of metal and is the "week link" in the design in my opinion. (I'm not saying it's a defective design). In any case my thoughts are that the heavier flywheel weight caused this because of the flywheel effect and when you drop the clutch hard (the wife likes to do that) that this put a bigger load on those stems. While this is only my theory on how this happened and how it is related to the flywheel weight. So any ways, I thought I would just show the after math of my wifes abuse<G>. DW

    Slightly broken clutch assymbly

    This is what happened to the wife’s crf150r back in July. Sorry it has taken so long to post. http://helibuf.com/dirt/crf150r/kodak%20028.jpg http://helibuf.com/dirt/crf150r/kodak%20029.jpg I had just installed a heavier flywheel on her bike and we went riding for the weekend at Kennedy meadows. We were about 20 miles into a 25mile trip and the side of her case blew out. After inspection the bike you could tell where the clutch broke and this let the bolt / spring assembly bounce around in side the case. This of course didn't last long as it blew the side out. While I’m not implying that the heavier flywheel had any thing to do with it, I’m just not wondering if between that and riding slow rocky trails didn't lead to the clutches demise. The worse part is that when I purchased the bike I bought an extended warrantee and of course in find print says "it does not cover any thing to do with the clutch or clutch system". I found that out after taking it into the Honda shop to be fixed and had to give them a deposit to look at the bike and would be reimbursed if the extended warrantee covered the work. Well, since they didn't cover it, the repairs ended up being extremly expensive. So I will never purchase another warrantee again or if I do... I’ll read the fine print first. Lesson learned<G>. Doug

    this is how I did mine. http://helibuf.com/dirt/acerbis%20rally%20pro%20handguards.htm Doug
  7. So after reading a few old post about people replacing there clutches and leaving the "jutter springs" out, I'm finding my self wonder if I should use them or not. I just purchased a new clutch and it is made to not use the jutter springs, all the fiber pads are the same. So I'm looking for thoughts and experience on leaving them out and what people have to say about how the bike handles not having them. My biggest worry would be if not using the springs would end up being to much strain on the pressure plate and end up cracking it. I only worry about this because my wifes new crf150r broke the pressure plate after some trail riding and i can see how this might be a weak link in the design due to the partial mounting surface that the spings sit into. Thanks. doug
  8. I'm looking for some input on which weight of oil to order for the tranny side of my 250x. I'm not sure which weight I should use. Thanks Doug

  10. I'm looking for an alternative to Honda hp4m oil and was wonder what would be Maxima's or belrays equivalent oil be? thanks Doug
  11. HI I have a accident case involving a 04 klx-110. However we I need to find one to test speed / performance of the bike. So what I'm looking for is to do some acceleration tests and some speed tests with the bike. This testing will not take very long, maybe 1 hour or less I would think. We will not be doing any thing destructive with the bike other the a few short runs for speed / acceleration. We can reimburse for your time. We are in the Valencia area of Los Angeles and can set up to meet some place convenient, either during the week or weekend. Please either post any questions and or send a PC. Thanks Doug

  13. this is for work. some guy biffed in it and I'm trying to find out if it was safe to use. that is why I'm looking for the maker to see if it was indeed approved.
  14. Hi I'm trying to identify this "ncr racing helmet". however I'm not even sure if this is indeed the manufacturer. could you take a look at these 2 photos and see if you recognize the make / model please. also any idea if it is dot or snell approved? any useful information on where to search or find more info would be helpful. http://helibuf.com/dirt/helmet%201.jpg http://helibuf.com/dirt/helmet%202.jpg thanks Doug

    jetting for Kennedy meadows (6000+ altitude)?

    I ended up jetting the bike with a 130main, 40sj, stock needle 2 clips from the top. the bike ran more then decent enough to ride all though it was just a bit rich off of idle. i probably could have turned in the idle screw a bit but just for a weekend of riding it wasn't that bad. however, as luck would have it, one of the springs / bolts broke off of the clutch basket and tore a 3 in hole out of the right side case.
