Turn choke on.Turn the throttle 4-5 times. Kick with your hand off the throttle.

It should start then die. Turn 2 more times kick again.

I have an 04 with about 12 hours on it. It always starts on about the 10th or more kicks since new. Only when it is warm does it start on first or second kick.

My 04 almost always fires 2nd or 3rd kick. Once I learned how to start it.

First, take exhaust plug out. Something I always seem to forget.

Turn gas on, pull choke out, wait a few seconds, then twist throttle 3-4 times. Bike should fire, idle , then die. Twist 2 more times, Kick and bike should then fire and idle. Sometimes I have to start a third time with NO twists of the throttle.

Also, for those coming off a 2 stroke, you have to learn how to kick it also. Smooth stroke and follow thru. Don't jab at it. :) My buddy just picked his 04 up new years eve. I had to start it at the dealer and for the first part of the day the following day. He was starting it fine by the end of the day.

My 04 fires up first kick, all the time. But didn't always do that. I had an 02 CRF and it fired up so easily it was ridiculus... made everybody else jealous. The 04 wasn't so easy at first and it aggravated me. Installed the powernow, JD jet kit, and ZipTy Racing fuel screw - and it fires up easier than my sons XR50. Funny thing to watch out for, when I installed the ZipTy fuel screw, I realized the stock fuel screw had fallen out! Gone. Nothing. That was why my bike was running lean too. Now it's perfect.

Start procedures are exactly as described above:

- Exhaust plug out - I forget that all the time too.

- Gas on.

- Choke on.

- I slowly kick it through a couple times just to get things moving (this is a holdover from my CR500 days).

- 3 twists of throttle.

- Full kick from TDC with NO THROTTLE.

- Fires up then dies.

- 2 more twists of throttle.

- Full kick from TDC with NO THROTTLE.

- Fires up.

Good luck.

"First, take exhaust plug out. Something I always seem to forget."

That fires my ass when I forget to do that! I have 40+ hours on my rig, no valve tweaking yet and it will fire first kick cold if you put it through the routine...choke, blip blip, kick kick, KICK and FRRRRRRRRTNAAAAAAAAAAAN

Actually my bike has always been a bear to start on cold mornings as well. Recently I put the JD kit in. I was in my garage changing my oil and my bike didn't have any oil in it, or the gas turned on, or the choke on. I pushed on the kickstart to get some of the old oil out of it and it started right up! Of course that kind of sucked but I killed it right away. Good thing I run a good synthetic that tends to really cling to those internal components. Anyway I now have the jet kit pretty dialed in (the technical support and directions for my conditions were pretty useless) and that bike definitely starts a bit easier as well as hits a bit harder and pulls a bit longer.

Yah, I know but the thing has always been real tough to start when it is cold outside and the thing hasn't been ran in awhile. Then I kicked it at about half speed. Oh well, it wasn't long enough to make any difference at all. Everything is still completely coated w/ good 'ole Mobil 1 for a good few seconds even w/ the oil drained out of it. Live and learn I always say.

There was a letter in the paper in the auto section from a guy who wrote in bragging how he would drain his oil and then start his car and run it for a minute to get ALL the dirty oil out...some people. The columnists mockedhim and told him that he must tell people he did that when he sells the car!

ALSO, make sure your Idle is not set too high. It will always cause hard starting if it is.

like i said this is my third CRF 450 02, 03, now the 04. none of the other CRF's exibited this starting trait when cold. I have been religous about valve adjustments with all the bikes just because of how high they rev. I live in anchorage ak and would like to stud up and ride the 04 in the winter just like I did with the 02 and 03, but I'm concerned that the bike wouldn't start by the time i transported it to the track when it's cold outside. when the bike does finally start, it backfires and pops until warm, then starts(even in gear w/clutch in)and runs perfectly.

Make sure your fuel screw is still in place. Mine fell out and caused the bike to run lean - hard starting and lots of popping until warm.

      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?
