Engin kits vs engine kits? (2 stroke for bicycle)
What's the current status on the differences between engines?
I've partially read a thread from 2008 on this forum, but believe that a lot of the info may be outdated.
I know there is the 49cc, and the 66cc (aka 72cc or 80cc) kit.
I've also seen some kits with different color engine.
I believe to keep the engine as cool as possible, to keep it naked color, not layer it with an insulation of paint.
I'm not looking for those differences, but the differences between the quality of the materials used.
Like, sometimes you find sellers selling an old kit with worse parts for a new kit's price. I don't want that. I'm willing to spend a few bucks extra, if I can know why I'm paying more (eg: improved engine design, better parts, improved performance, etc...)
Any other differences between engines (eg: are there good engines and bad ones, or are about all engines the same where ever you buy them)?
