Chris said: On paper, the formula looks like all engines will be equal, but in reality, when they get race prepped, the outcome is very different…In all honesty, unless one motor is like 10hp more than another, the choice is pretty simple, buy a motor you can readily get parts for….. I get parts for various KZ engines with no problems. I went to a local Honda shop for a piston one day….shop had to order it from a warehouse in Iowa. Now with CR125 out of production parts will get even harder to get. I like to think of the CR125 as a ‘Johnny Cash’ engine ‘One Piece At a Time’.
I can get parts for various anything with no problem also, I can’t however walk into my local kart shop and order a KZ anything, I don’t have one, but I do have a local Honda shop that I can order parts from.
And for the millionth time, the 1999 CR125 kart engine is not out of production, it is very much alive and well, factory supported, has a factory contingency, a racer parts program, and the best part, a FACTORY MANUAL!!!
The TM K”whatever” through K10a is out of production. Plenty on the shelf though collecting dust….
