660 Yamaha grizzly Into 450 Yamaha Kodiak Engine Swap

Recommended Posts

Just a quick question, I was wondering if anyone knows if a Grizzly 660 motor can be fitted into a Kodiak 450? My motor needs rebuilt and I figured I would see if that could be done instead. Basically will it fit, work, and can be used with the same transmission?

What year is the Kodiak? Since the transmission and the motor are encased in the same body, you don't need to worry about the Kodiaks transmission, the Grizzly motor will have its own. As far as fitting the 660 motor in the Kodiak, where there is a will there is a way, people put 4cylinder streetbike engines into sport quads. The question is not so much will it fit and work, but can YOU do it.

Alright thanks, it's a 05 auto 450 4X4 IRS.

Could it be done fairly easily and I would like everything to work correctly, like my stock screen and such.

Where's the best place to find a motor?

I had an '04 Kodiak, nic emachine. This is a first, but I think it may work. I would check out diagrams of bolt patterns, etc...first. Go to a site like BikeBandit and look at the two machine's engine diagrams. Bolt pattern is the first thing to look at.

Ajmboy has a good point, those motors could be very similar, especially on the bottom end. I would search ebay for a good motor, just make sure that you only buy from people with an excellent sellers rep. As far as it being easy, unless the engines share the same engine case, no, it probably wont be easy. Most engine swaps require a good amount of planning, fabrication and you need to be able to improvise. You will most likely need to be able to weld, or know someone who can.

      Unfortunately I didn't notice some of the rust hitting the undercarriage of my 2004 Yamaha Grizzly 660, but saw it the other day when I was doing some maintenance, oil change, air filter, spark plug, etc. The left side footrest broke and that's causing the plastic to hit the front wheel. It broke right at the welds from too much rust. Looks to me like what I need is (looked this up on yamahapartshouse.com):
      YAMAHA FOOTREST BOARD 5KM-27481-10 Left side (broken)
      YAMAHA FOOTREST BOARD 5KM-27488-10-00 Right side (rusted and will probably break eventually)

       
      Does anyone have a less expensive source? I did see on ebay a couple of listings but it still comes out to @ $50 each,

      x   just bought this expedition 425 and the Speedo needle does not work. The lights work for the shift indcator. So is this an electronic Speedo or cable? Is there a way to fix it or will I have to replace the unit? Thanks for any help you can provide.

      Hi guys I'm in the market for a new ATV.  I narrowed my choices down to King quad 750 Grizzly 700 and Rubicon 520,  I own a 2006 500 Rubicon right now and I like the reliability and power for plowing.  However it is not a capable ATV.  When quading with other guys it falls short with ride quality and ground clearance.   I also have a 500 King Quad 2015 which I like and will keep it for my wife.  It is very strong and reliable also.  However my plan is to sell my Honda Rubicon and replace it with a 2020 of one of the these mentioned above.  Can anyone give me their take on one or all of these machines and why you picked what you picked?

      I know this tooic has been addressed by many, I’ve looked through many forums and pages. I did not find anything like the problem i have.
      I have a 2007 Kingquad 450. I have a new fully charged battery. When i turn the key, the dash flashes and seems to struggle before getting fully lite. We can hear a small relay near the computer clicking, i think it is the fuel pump relay. When i turn off the engine kill switch and press the starting button relays click and all the power shuts off, i turn the key off, engine kill switch then start over, power is there. Atv will start with pull start, but not elextricly. if i try to use my winch, all power cuts and engine dies. 
       
      Can anyone tell me what it may be? or has anyone fsced an issue like this before?

      I have a 2018 Kodiak 450 EPS that just this past Sunday I ran through a bit of water.
      After the puddle the belt was slipping, so I pulled over and drained the ultramatic housing and the slipping problem went away. This was all in L and everything seemed to work fine. Later when I got on a road, I put it in H, but it still rode like it was in low... i.e. I had to rev it up a lot just to get to 30mph.
      When at home I pulled the ultramatic cover off to inspect, and it looked okay in there. Not much dirt, belt and everything are clean, but when I rev up the engine (with cage in place, of course), the belt doesn't get to the top of the clutch (maxes out about an inch or 1.5" from top of clutch, so maybe it is normal).. I put it back together but same thing... H seems like L still.
      Do you think the clutch needs to be further dissected for cleaning, or could this be an issue with the gear selector?

      I have a 2018 450 and the digital gause has started flashing on an off while driving. The backlit also goes on and off. It is worse when I hit the gas. The battery died a few weeks ago and I jumped it but its been fine until last night. Called the dealer and showed them a vid and they recommend replacing the gauge and its like 600 bucks. The machine has less than 100 hours on it. I would really hate to have to change it out. also the unit sometimes has trouble starting. Any ideas?
