One fast CRF.... Yoshimira Motor Mods??

Recommended Posts

Probably just rode the fastest CRF450 I will ever get to ride. I friend of mine bought one of Kyle Lewis's 04 supercross bikes, and yes, its genuine for all you skeptics. Ive got to tell you, this thing is crazy, crazy fast, but still pretty rideable. The track we ride at in town, is pretty tight with lots of corners, some hard pack, but its mostly a sand mix, and there are only a couple places I could even think of twisting it to the stop, from the bottom to the top in the revs, the power is seamless, and endless. I practiced a few starts with it today, and it made my motor feel like I was riding a XR, we've all seen that his bikes are fast, I just had no friggin idea they were this fast.......:cry: :cry: :cry:

They stuck a set of his Noleen mod'ed outdoor suspension on it, it works damn good too, I figured it would still be so stiff for a mortal that it would rattle your teeth out.

One thing I noticed however, was the lack of engine braking compared to my 04, Im not sure how this is accomplished, but I like to hear from the motor experts on how thats done??? Its by far the fastest thing I have ever ridden, hands down...

A guy that works for him has bought a couple of them in the past, not sure how that dude got to know the people at Moto XXX, it cost the same as a new bike, the rims have some dents, but other than that, the bikes fairly clean. I though he was nuts for buying it, that was until I rode it a few times:worthy:

I know what you mean about fast 450's....a juiced up one is just...insanely fast...the part about trying to hang on to one for a 25 minute moto (much less 35 minutes!!!) is true. You have to AGREE with it on certain things...or it will eat your lunch.

I am making the 250F my bitch, compared to the 450 making me it's. :cry:

slipper clutch.

Really, I'll have to get him to check that. Ive heard a couple times that lots of the teams are using those on the 4 strokes.

One things for sure about that motor, you had better be pointed in the right direction when you pull the trigger, I had a couple moments today on it, and I thought I was being pretty smooth. One corner on the track is deep, soft sand, I was layed over pretty close to horizontal, and the thing was pulling the front tire of the ground, it made me laugh and shake my head, just couldnt believe the power that thing has. I definately do not need anything that fast.....

I'm also pretty sure it's a slipper clutch. A slipper clutch is a special clutch that disengages the clutch under deceleration so that engine braking isn't applied to the rear tire.

      I just bought a Magura hydraulic clutch for my 2014 CRF450R.  Bought it thinking install would be easy, and I'm not sure that's the case now that I have the product in my hands.  I have searched the forums, YouTube, etc for install help specifically for my model year (2013 and 2014 are same really), and haven't found anything specific for the 2013-2014 model install at all.  Instructions from Magura are TERRIBLE, and are not specific at all to the Honda - generic instructions - so I'm debating if I want to return the product, cuz I don't want trouble or a big install job.  Question: for the 2013-2014 CRF450R install ONLY of a Magura Hymec hydraulic clutch - other model years are different and thus it won't be helpful for other model years - do you have any tips or feedback?  My concerns are below...
      1.  The 2014 model has a sleeve behind the clutch actuation arm that the Magura clutch slave cylinder fits into.  Stock, the sleeve holds one end of the cable, with a nut on the other end to keep the cable end tight in the sleeve.  The Magura slave cylinder, however, slides into the mounting sleeve  - but does NOT have a nut: the tension from the clutch actuation arm pulling on the metal Magura slave cyl tip end is apparently supposed to keep the Magura slave cylinder tight in the mounting sleeve.  Q: Will the Magura slave fit in to the mounting sleeve easily, stay tight, and is there any adjustment needed in order to keep the 4-6mm of freeplay that Magura recommends?  How easy is it to get the Magura slave fitted into the sleeve and the metal tip in place?  Is there enough freeplay between slave and tip end to mount in actuating arm AND the holding sleeve, so that the holding sleeve doesn't need to be unbolted?  
      2. The stock clutch cable and OEM setup runs out of the mounting sleeve (see pics marked "metal starts", and then runs through a metal sleeve that routes the cable through the engine compartment - keeping the cable away from the hot parts of the engine case, so as not to melt the cable insulation (I believe).  That metal sleeve is about 6-8 inches in length.  The Magura clutch cable, on the other hand, exits the Magura slave cylinder at an angle - yet has no such metal routing.  I don't think the OEM metal routing sleeve will accept the Magura cable either, so a) the OEM metal routing sleeve would have to be removed first before installing the Magura - and then b) you have to hope that the Magura cable can be routed in such a way with zip ties holding the hydraulic line that line will not touch or be close to the hot metal engine casing as you route it through the engine.  Q: how easy was it to get the OEM clutch cable and metal routing sleeve out?  Easy as unscrewing the nut on the other end of the OEM cable, on the other side of the black rubber cable flange in my pics?   
      3.  My stock clutch pull isn't bad.  I just like the feel of a hydro clutch.  Any feedback on how much better feeling and easier pull will be with the Magura?  What's your feedback on the difference?  FYI, I'm leaving my clutch plates and springs stock.

      We have a 2016 CRF450R with about 11 hours out. never ridden hard always check the oil and change when needed along with the air filter. Took care of the recall that was required as well. Well when riding the bike was stalled out. Went to try and kick start the bike again. the kick start lever just back up jamming my knee into the handle bars and some how ended up cracking the case right by where the kick start goes through the case. Has any one had this happen or heard of this happening? What is the cause?

      Any advice on what should be replaced while I have the top end off for a valve replacement. Will do headgasket and springs of course, anything other parts you would recommend while I'm going at it?
       
      Thanks!

      The dirtbike is on it's forth year right now on the same motor job. I have to jump start it. Is it worth me trading for a 2009 650 brute force with7000 miles? Need some expert advice. Thanks

      Just wondering what you guys do to remove black marks on your seat. My 08 crf450r has the red/black seat, and after each ride there are some black marks on the red from my riding pants. Not scuff marks, more like patches of black residue from my pants rubbing on the seat. I’ve tried the magic eraser which seemed to do the trick, but lately they seem like they aren’t coming off. Also tried scrubbing bubbles with a brush and no luck. Not too worried cuz I have an spare OEM seat, but I’d like to keep this one nice. Any ideas? Maybe I shouldn’t wear black pants?
