Here is the issue. RAW engines kits keep claiming to "Be the best" yet they have not pointed out how they are "the best" and in fact keep talking in circles when asked how they are "the best".RAWS are good. Built 2 w/ no motor issues.
Maybe in China pi is really 3.6 instead of 3.14??? That'll get you to 79.524ccDude,
66cc, 80cc who knows? Maybe it's Hong Kong math?
For the 80cc it reads: 47mm bore X 40mm stroke = 80cm3 If you do the math it comes out to 69cc. The advertised bore and stroke are correct. Their math used to arrive at the cc value of 80 is not!
Yes...Yes, In the shop you can make proper parts that drastically improve these kits.I have used three different kits from three different supplyers. One of them was a Raw. They were all basicly the same. I didn't seem to have any real trouble with any of them. The one from thatsdax seems to run a little smoother. I do replace alot of the parts, such as mounting brackets and chain tightner, with my own made in my machine shop.
