Hey everyone,
I am considering building my first motorized bike and have doing some looking around the internet to figure out what would be best.
So far it appears that Grubee (SkyHawk, SkyFire,...) are some of the most highly rated products. Anyone have any thoughts or recommendations on what engine to buy? What is the biggest difference between these and some of the cheaper kits you can buy?
I want an engine that mounts in the middle of the frame (like the 2-stokes do), not something that has to be mounted on the back of the bike.
I live in Albuquerque, NM at an altitude of 5200ft. I have heard that the small 2 strokes don't perform well at high altitudes. I will just be using the bike to commute to/from work mainly, and not doing many intense hills or anything. What engine/setup would you recommend for this type of use.
I had someone recommend buying the 80cc(really 66cc) engine, as well as a shifter kit, and a Dellorto carb (for better idle, low speed, and transition to high rpm). My question is this, how much will the shifter kit and carb affect the performance of the engine. The carb isn't that expensive, but the shifter kit is like $200. Is it really worth it?
I am just trying to find out more info before I buy something. I want to be satisfied with what I get, not wishing I had done more research. Any input would be appreciated!
Thanks!
