Re: I find the Tanak PF-4000 ear shattering loud !
Yea !! Can you belive it. I had the belt drive kit prior to this. When I bought that around 2002, it came with the Zenoah 25.4cc It had a surprizing amount of power. We had us and camping gear totaling 450 lbs on board plus the bikes weigt itself and engine weight on one trip. We've climed steep hills too. Not on the same day with the camping stuff.
I'm going back to that engine. The sound level was more like a common stringtrimmer. The Tanaka 40cc sounds like a very loud chainsaw. And I'm talking more like a big 20inch or better saw. I had a 3.3 cu in. ( about 57 cc ) Poulan chain saw and its louder that.
