Modified Wiring Harness

[859davidt]

Anyone know of a modified wiring harness without all the extra nonusable wires for an mx bike. I have an 05 450r and would like to keep the fan running. I have seen CRF ignitions with clean harness, but then they had a battery to run there fan. Any info would be greatly appreciated.

I just removed all the wires from a 05 450r for a guy last week. You need to find a manual and follow the diagram and remove all that isn't needed.

Did you shorten it up to keep all wires up front or did you run them to the back? I did my 400ex in 02 with the battery up front under the hood, took a few days but I got it. I am unsure on what if any would run the fan if you take to much out. Is it possible for the 450 to run without the rectifirer???

[hondaracing_13]

I just opened the wireing and removed all the light wires, brake light switch, bar control wires and key ignition. I think you need to keep the rectifirer. I may have some notes I used, I will have to look when I go to the shop.

I took mine to toby at moto-xperts.....he did mine up all nice and clean, wired the fan to run constantly. I'm very happy with his work. I don't know about you guys, but i have nightmares about electrical problems so I leave it up to the professionals and now I know I won't have any problems

I just built some of the 04/05 harnesses for cutomers. eliminated everything not needed and put kill switch plug in and located the rectifier up front. on the 06/08 I eliminate all the electric start stuff and put in the condenser. Thanks, Rich 17 racing. email me at dajrrich@gmail.com

Baldwin did my 450R harness when I had it for $45. He wired in my tether and we relocated the rectifier to the front shock tower. Super clean setup.

patrickj75 or billetrich, were you guys still able to run the fan?

[skyeryder]

Yes you'll be able to run your fan all the time, you can do a search on here and it'll find the thread that tells exactly how and which wires

Baldwin can do wiring harnesses, give them a call

Yep, the fan still worked. Took out the key also. The tether was my only kill switch. I'm sure you could also wire in a handlebar mounted button also.

we have an electric start, what wires can be eliminated? and still keep the key and fan? what is a good start button to use? any plug in systems?

Rich17 Racing did my harness and it works great. He convereted my 06 electric harness to a kick only harness and cut out everything that was not needed and relocated the rectifor to the front. Great clean work by Rich17.
