The pipe will definitely be original. Our plans are to use a portion of the k5 head pipe, and the rest of it will be hand coned by Robl Engineering.

Whatever Troy comes up with i'm sure it will kick ass

Just don't be taking too much of his time away from developing intakes and air boxes for our 250r's! :lol:

We'll play around with the pipes. I'll start with a hodge-podge of the original pipe and the old pipe from Elly as a baseline. I also have an LRD big bore pipe that Pete loaned me that we may try as well. Nice thing is I have my own dyno so we'll dial it in. As far as new hand cones, we'll probably do some dyno pipes based on the simulation software I'm using then take what we learn there and make one snake thru the frame. ..basically we're going to experiment a little. This will be a torque build (i.e. MX/XC) not drag bike.

Look out.....

You guys may try getting a hold of a Zilla Lrd pipe and talk to Jerry about some of his designs for ideas both are a torque mid range to top end pipe.

This is my 500R pipe I build for my Saber MX bike, Elly. I like making my own pipes. This one was designed around the CR500 porting specs.

Will for sure be keeping on eye on the build. Currently on the lookout for a KX500 myself, want to build a "Team Green" replica desert racer. If I could pull the motor out of the bike and install it in a quad chassis, even better, think I would prefer a TRX450R chassis though, since I have two of them sitting in my garage.

Troy, about how tall is a KX500 motor? Want to compare to a 450R motor.

Doug it's definitely shorter than a 450r motor. It fits the r frame rails without modding the upper rails... It's very similar in size height wise to my saber. We'll have to pull the tank to swap plugs. The neat thing about this engine is it's super light even compared to a 250r motor. Were going to try and avoid moving the pivot bolt, cause the 250r anti squat is pretty good but there is slight interference with the peg mount tube or main tube. We'll pocket it to fit. The 450r pivot is a little higher which would be would help for that issue, but poses a higher cg....

I know a guy that put a kx500 in an atc 250r frame and it for in there really nice. He used the stock pivot location but had to mod the cradle a little. The chain alignment was a little off. It should fit in the quad real nice. Those kx500 motors with the power valves are complete different animal than anything else.

I'm going to have to meet up with you at Little Sahara when its done to see it run!

Kx500 is a little over 14 inches tall

Any progress on this? I would like to see the results!

My uncle is putting the same motor in a ATC frame it's going to be wicked fast!!!
