Re: Oi Mates! - Calvin W. Cline
Yes, my suggestion is that if this is your first motorized bicycle that you forego the aftermarket parts and build your bike as simple as you can. You need to gain experience and deal with the inevitable growing pains before complicating the build with so-called, 'performance parts'.
The jury is still out on the advantage, if any, of the booste bottle and the shift kits can complicate the installation of an engine kit.
Start simple and then after you've gained some experience move up from there. You'll have enough to keep you busy with the basic engine kit without adding anything.
But then, that's just one opinion.
Along with that, welcome to the forum.
Good luck and ride safe.
