further more as i got the practically new engine for only 375$ USD, it leaves me a budget to pick up the 314cc big bore kit when i get back out to asia...

Hope people recall this number when $600+ for a new 167fmm is tossed around. you are entirely correct, the price for this low performance engine in the US is at least 4x what it should be because there is little to no desire for it.
