Re: 50 to 44 tooth swap
Because the are full of you-know-what, or they have an inaccurate way of reading their speed. Having said that, I will say this- some engines will rev, and some won't.
I am not calling anybody a liar, so don't get your panties in a bunch. The first bike I built, I SWEAR would go 45 mph as clocked by two cars, most called me a liar, and the rest of the bikes I built wouldn't even come close to that speed. I wish I had that engine now that I have GPS.
