If rumor is the 06 has FI, then why none in the 450 supercrossers

Recommended Posts

read plenty of rumor threads on FI for 06 but has anyone spotted that on a supercrosser. personally after having a 2003 cbr1100xx it never took more than 2 seconds to crank hot or cold and never hesitated from a cold start to 100+mph

in my opinion there will never be fi on a straight up motorcross bike. you will have to ad weight with a pump and various other sensors and a larger ignition module. i think that there could possibly be fi on the off road models like the crfx, drz, wr, but deffinetly not on the motorcross models.

FI isnt going to be on 2006 production bikes. Rumor has is that maybe they'll have it on the 07's.

Keep in mind FI was also "rumored" to be on the 04 and 05 models. Rumors are just that.....rumors.

Why? Its most likely not going to be a closed-loop EFI like on a car, so it wont reprogram itself and if that is the case I will be surprised if them manufacturers make reprogramming easy or cheap.

I'd rather stick with a carb.

I pointed it out in another thread but I'll do it again. Go look at www.usmontesa.com A trials Honda thumper with fuel injection. Not its not big heavy or bulky and no it doesn't have a battery.

I don't expect to see FI on a MX'er for a few more years though (my guess is 08). Honda probably wants to work out all the kinks on a small volume market first. It will come its just a matter of time, market pressure and the corporate bottom line.

Not to mention that at .13 micron feature sizes (pretty typical these days) you can add a few million transistors to the ECU and never and the difference will be like 1 square centimeter and a couple nanograms. I'm thinking FI for a competetive MXer will add too much cost so Honda is foot dragging as long as is legal.

Well guys remember the Cannondale, they have FI I dont know what type of FI it is but it has it. If they (Cannondale) can put it on a bike why can't the Jap's. I'm sure they can. I believe that they will, eventually. On a diiferent note, if 4 wheel disc brakes are very good, to which i agree, then why don't all vehicles regardless of make put 4 wheel disc brakes on their products. Yes it's the cost, we will probably have to pay more for FI, but the more research and developement that is done on FI the cheaper it will become. Hopefully we won't have to wait to long for it. Just my two cents worth. :cry:

Honda IS experimenting with FI. If you look close at this photo from the Jap Nationals last autumn you can see two wires going from the exhaust header....

Just because there is an oxygen sensor in the exhaust doesn't mean that there is a FI unit on the bike. It may be there to help with getting the carb fuel/air ratio setup.

Ride on

The Montesa trials bike is Honda powered and FI.

Trials bikes are ALL about light weight. Look in to it, it is a very interesting setup.

The FI unit powers up from kickstarting.

      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?
