Just a look at the Rekluse
used in another type of bike. In the Yamaha
400~450's it works well but.....
For the tricked out XR650R -> What a piece of junk!!!!!!!!! It lasted less then a year in race conditions. 1200 miles. I know there are riders out there that like it for trail riding and I have said, 'it works for that" so before the few of you flame on me that use it for that, I want to say for racing it sucks!!!!!!!!! Two bikes the CRF250 (bored) and 680cc XR650r with cam have had nothing but, trouble. The XR650R Finlay busted off the tabs of the clutch basket. I talked to Al Youngworth many times and he seems like a very nice guy. I called within the 30 day to return it but, he talked me into keeping it and he would send me a newer model to try that disengages the pressure plate like a real clutch. He didn't and I called many times. I never got a newer better nothing. In the end I had a clutch basket get destroyed and it is defiantly caused by the Rekluse
clutch. It applies the pressure mostly at the top of the basket and not evenly over all the disks. I am not happy with the out come and think that I was right in trying to return this clutch for what I was going to apply if for. So, in the end, if you are going to race your bike or put it through it full potential Don't use this Clutch!
Well, I am sure I have lugged the bike at times but, not in higher gears. I do keep the rev's up and am usually all on or all off "balls to the wall" rider. I do not think I should have to completely change my riding style to make an after market piece of junk work while racing. The shock from coming out of orbit and going to WOT is what ripped this clutch basket apart. Would never happen with a stock clutch setup....never. I am not going to baby the bike coming off a four foot drop off into a wash because the clutch can't handle it. It was nothing but trouble to drop two in the heat of the moment and this time the clutch (Z-start) is fully responsible for the destruction. It applies almost all the pressure on the disk just below the pressure plate. I was in the air off the side of a hill mid~upper third got about 4+ feet of air from the bottom of the tires and landed 54 feet from take off, on landing I grabbed the throttle to lock (WOT) and the z-clutch applied all the pressure to the first plate and that plate took out all the posts off the clutch basket. Yes, I agree if you are not going to uses all the bikes power in every and anything coming at you this clutch will work but, anything close to either extreme (lugging or racing) forget this junk and move on. Al Youngworth has a good idea on the clutch I never got and I would have loved to have had it but, I was forgotten and I got tired of calling trying to make it happen. He didn't keep his word and I was dropped. If it would have come about and worked it would have been good advertising but, this clutch stinks on the DRZ400E also. Pastrona used it for a while and had nothing but, trouble shifting. DRZ and XR650R do not have a tranny that was designed to handle clutch-less shifts well. The CR, CRF, KTM are also in the rpm's almost always, very few times will I find myself anywhere near 3000rpm or below on these higher strung bikes so, wearing the clutch disks or scorching them isn't as much of an issue. One other major issue I have with the Rekluse is the throw-out bearing! This was way toasted on mine and caused much play in the pressure plate. Not designed to handle the bike just made to work with what they made. They have a good Idea and made it work without infringing on other patents not engineered something to withstand the full power of our bike. I am mostly unhappy because I was led along so I wouldn't return the thing inside the 30 days of the money back guarantee. I believed he was making a tricked out auto clutch and I was going to get to test it. I called, wanted to used it in three different Baja races but, in the end it all turned out to be a snow job.
Just to give insight to the throw out bearing, I did have a clutch perch adjuster - thing. So, yes, I would try to use it to slip the clutch at times and hammer it when I needed it to down shift now, in a hurry, hoping it would help release the clutch sooner. It does help but, at break neck speeds sometimes you want the clutch to disengage now!
