custom coolant recovery tank

[moto9]

Here's a cheap and easy to make coolant recovery tank.
You can use any diameter or length pipe to suite your needs.
I used 1-1/2" pvc pipe
2) 1-1/2'' id end caps
clear tubing
2) npt barbed ends and some thread tape
Cut the pipe to length...you need
drill a hole in the center of both end caps
tap threads into the cap, I used a flare tap, and tapped so that the barbed fitting fits tight into the first couple of threads...that way you get a tight seal
tape the threads of the fittings and tighten them into the caps
use pvc glue and spread a thin layer into the ends of the pipe and assemble the caps into place.
Let the glue set for a while and attach to the bike.
The bottom tank fitting connects to the radiator over flow nipple just under the cap, the top tank fitting is a vent, that should route some where below the engine.
add a little coolant to the tank, that's it.
I got the pvc pipe free, I already had a tap and tape, so all I had to buy was the end caps, I spent about $5.00 on the whole thing.
