Every year I hit Doug Ruth up for his latest "wiggle" in motor work. He works very close with many of the top engine builders around the globe and because of this there is always something fresh... Being an "early adopter" by nature, I love trying out the latest and greatest. To date, with all the Poo 1200 triples, CR500's, and straight up twins I have yet to be let down. Just amazing, he knows his stuff!
This experiment is derived from what has worked very well the past few seasons on the boosted Poo motors; which gave the turbo'd motor increased bottom end without giving up top end perf. So, the old big bore, war wagon, rolling lab had to give it a try Supposed to give some increased crankcase compression, better low-mid, and not hurt top end.
I love the machine and porting work he does.....thought you guys might too..... I gave him my motor and let him "have at it". Below are some pics, notice the head, it has the "bathtub" style of combustion chamber used by Union Bay Racing (where he ported for almost 10 years) and now adopted by Power Addiction Racing. Proven to give low-mid torque increase.
A plug thread would not be complete without a link: www.ruthpower.com
Other motor work he has done for me over the years....
