Re: need some help on choosing a kit!
I routinely ride over 75-100 miles a day in the summer on my HT powered Pig with no problems at all. These engines can easily run all day if you ride them like they were designed. 40mph in traffic is NOT what they were designed for.
Take it easy and they will run forever. Above 7k rpm, things get....interesting.
If more is better, then too much is just enough.
If you can't afford it, build it yourself.
