Nice! Thanks for posting this!
For those who have not yet seen this site it`s worth a look....Yen is about 10 to the $ at the end of August `13.
This site has oil filter cover diverters for fitting of an oil cooler.
And for oil coolers and related: Pit Bike Engine Parts - Oil Coolers & Oil Filters - TBolt USA, LLC
Also: Yamaha TW200 Parts and Performance - ProCycle
Watch out for those exchange rates for the Yen, it changes often but not much at at a time...
The dollar to yen is NOT 10yen to the dollar. Its 96yen to the dollar. Here is the math. It cost 110yen for a can of coke. Does that sound cheap to you. Not to mention shipping in Japan is ridiculous.
You can buy an oil cooler kit from LizardBreath. He was the MAN to do the research and get it to happen. Support your local TDubbers.
The Lizrd cooler is sweet, I love mine!
Only a fool would attempt it, and God help me, I am that fool!
