    2008 Kawasaki KFX 450R Service Manual
  3. Tagels


  4. So i recently bought a Honda TRX 450r 05 kick start model i am the 3rd owner. this bike ripped when it was running but i ceased it.I freed up the piston but there is little compression now. i think i ran it out of oil but it was like 20hrs or so since the last oil change. My real question is that i heard you have to rebuild the top end every 15 hours is this true? Now i have bought a new big bore kit to replace the cylinder and the piston but i dont really want to have to rebuild it every 15hrs.
  5. I'm brand new to riding. Also brand new to fixing and/or maintaining a vehicle. I picked up a 2008 KFX a couple months ago and just realized that a wire was hanging. After downloading the owner's manual, I think I may have narrowed it down to the "Inlet Air Temperature Sensor". It fits in a slot underneath the seat, in the air filter housing. I'm not sure how long it's been unplugged and, honestly, I have no idea what it does. How important is this piece? I'm going to the track this weekend. I'm not even sure how to reattach it. Any help is greatly appreciated. Videos here: [ame]http://www.youtube.com/watch?v=kvoRJexYDYc[/ame] [ame]http://www.youtube.com/watch?v=NRLYFFfu-Mw[/ame]

    2 Problems at the same time

    Took my 05 for a ride yesterday after getting it dynoed and tuned and it scared me. I had a dead empty tank before I started it (brother needed gas ) and when I was riding it at steady throttle I could feel it giving up a little and it was popping way more and backfiring on decel. I was riding with a friend who was also having problems with his quad when mine just gave up and died in 5th gear so I pulled in the clutch and popped it in 4th so it would start. It started and seemed to run fine after a while at a stop sign talking and worrying. Seemed to not "give up" on steady throttle after a while. I was thinking this all could be the result of a dirty carb since I had an empty tank (all the garbage at the bottom). Any input? Part 2 : Ever since before the dyno and tune my quad ticks steadily when I'm letting it out of first gear. Why would this be happening? Its a 2005 Honda 450r with a pro circuit full exhaust, k&n filter, no lid, no pre filter, and sprockets.
  8. I have a 450r and recently bought two hotdogz full exhausts for my 450r even though I have a pro circuit one(its really dirty anyway). I swapped them yesterday and it sounds a little lean (popping while giving steady low throttle) which seems normal because this pipe looks less restrictive. I don't think i'll have time to jet it before this Sunday so MY QUESTION IS: is it okay to run it for a few hours if the jetting isn't perfect?

    My 450r overheating?

    Well, I rode my 05 450r yesterday like I always do, maybe a little harder than usual. But then again I never beat on my bikes. Seemed to get really hot, but the fan didn't turn on! Nothing crazy like coolant boiling out of the radiator, but it was HOT. Ever since i bought it, it hasnt used a drop of Anti-freeze that's in it. Any help is appreciated

    450r swingarm question

    I recently bought my first 450r from a buddy of mine its a 2005 with a JD widening kit(i think thats the brand), pro circuit full exhaust, jet kit, k&n filter, outerwear, ITP rims, front bumber, AC six pack rack, custom seat, and i think its +4 on the swingarm. Would the swingarm give me trouble at an mx track? im definitely going to take off the lowering/widening kit
  13. I felt like making my 450r look a little more unique so i decided to paint a few parts. Tell me what you think of it!
  14.

    Kawasaki KFX 450R Intake

    Got my FCI intake today cant wait to put it on and see what kind of power gains it gives, if anyone is familer with this install and knows any tips let me know, I image it wont be to bad.
  17. Heres some pictures of my TRX450R after i got it all back together today, still need a grab bar though. I was just riding it around a while ago and WOW being 50" wide made a huge difference, definitely worth the money. And the new tires are SO much better then the stock ones, i feel like i actually have control over the quad haha. Also you can see me and my brothers moto-4 225 in the pics, we have beat the #$&! out of this thing and it just keeps on chugging! gotta love detuned utility atvs lol, plus we got it for free and it just needed 1 piece welded and a seat cover, which we made out of a old golfcart seat

    Unison VNX 450R

    The last couple of years, the Taiwanese based company, Unison has been working on a 450 racer. They are getting ready to release them. They actually teamed up with a company called Metrakit. Metrakit is a Barcelona based company that has been huge in the GT mini racing. Those 2 along with Fuji Heavy Industries, developed their racer. The motor was built in Japan by Fuji, which is the parent company of Suburu. The powerhouse is a 448cc DOHC 4 valve, liquid cooled, with a 36mm carb. It has a 5 speed manual with reverse, 520 O-ring final drive. Dual A-arms up front with preload adjustable piggyback shocks with 8" of travel. The rear is solid axle with rebound adjustable gas shock. The biggest problem I see with it is the weight, it comes in at 445lbs. DRY WEIGHT!!! It has a very similar look to the KTM in the hood and front fenders. The fenders are removable for the shaved look. Comes with nerfs, doesn't look to bad. The quality tends to be shakey at best with these off brands, I have a feeling that quality levels have been stepped up for this one. Seeing how they worked with 2 other companies that would not want to hurt their own name by releasing poorly made equipment. Unison, Fuji (parent of Suburu) and Metrakit really stepped up the off brand quad market this year.
  19. Hello I just bought a new KFX 450R 2009 and have been looking for a exhaust for it I am looking at the Lexx Exhaust it is just a slip on but the stock head pipe is pretty good so I think that's all I need. Anyone have any input on the Lexx or any exhaust for the KFX?

    Thinking on buying a TRX 450R??

    Hey guys I have a 2008 KFX 450R but am thinking of buying a new TRX450R who rides one and what do you like and dislike about them thanks!
  22. Hi I have a KFX450R 2008 model it has been great but I was riding the other day and I let off the throttle and it just died so I tried to start it back up and it would not start unless I gave it a little throttle and then would die again if I let completely off the throttle?? as soon as the machine cooled it will start fine without any throttle?? Keep in mind this is fuel injected so you shouldn't have to give it any throttle any help would be appreciated thanks.
