450 XCF Fan mod.

First off, thanks for the idea Sergio!

Started off with some free CPU fans from mom. (she works with computers) Thanks Mom!

Toggle switch, inline fuse, and some ring terminals from Radio shack-$10

Simpson strong ties from home depot-$3

34896 414065064266 763134266 4393138 3459447 n

34147 414065129266 763134266 4393140 4138084 n
I cut the little nubs off these tabs and drilled a hole through the tab. This allowed me to through bolt the brackets I made on the side of the radiator.
34147 414065134266 763134266 4393141 4145347 n
The custom brackets.
34896 414065069266 763134266 4393139 6894417 n
right side...
34896 414065059266 763134266 4393137 8383492 n
Both sides.

All wired up but the switch is just zip tied to my handle bar...Need to come up with a better way to mount it. I might get some more use out of that strong tie...Unless I can find something a little more "refined" at cycle gear.
Some engine ice and she ought to be good to go fer this Texas heat.
Cheers.

Good man. You need to clean and lube your chain lol. Looks like what we did on sergios bike. But we used aluminum diamond plate for the bracket lol. Gotta have that bling. Also don't forget to make sure the direction of the fans are correct.

That's what I was expecting you to say. EXCs come with a lighting coil and a battery, and any MX bike or that is electric start will be able to jumper right to the battery. However, any bike that is powered by magneto/CDI (kickstart only) won't be able to use this mod unless they install a battery just for fan purpose, which isn't a bad idea, actually. There are a few of these guys out there watching, so I wanted to point that out.

They probably can if they have lighting coils on their stator. Like if they have a headlight but no e-start. But you're right. If you don't have an e-start or a headlight. You can't run these just off the ignition coil from the stator.

Ive read a bunch of reviews on TT and they all say they don't have any problems with water. And I believe Pimpdaub has little to no trouble with his regarding water.
