Freeze, front brakes yes!
I don’t think a Jr1 should be using a 15hp World Formula engine and yes it probably would last twice as long at 6000rpm, maybe even the whole summer!
We have taken apart many Honda’s and measured them and they are very consistent but we still must check every engine to be sure they are the same and correct them if necessary.
We have sold and built Briggs engines since IMI has been in business and will still support them in the future. It is my opinion that the Honda is a better investment for the future of the sport at the Jr level.
It is also my opinion that nationally karting has suffered from the same rules that you support for Briggs. Their rules make karting more complex and expensive, this is one of the main reasons that karting has not been able to ever grow beyond a certain level. There has to be some part of this sport that is inexpensive to get into and inexpensive to run, especially for children. The rules have always left too much room for experimenting and blueprinting which results in the added financial ?competition? element to the formula.
There have been hundreds of customers in my shop looking to get into the sport with their children and the two most common objections are cost and complexity. If we can offer a package, which is inexpensive to purchase, low maintenance and simple to understand and operate, the objections will be overcome. This will also keep people in the sport longer when they are having fun being competitive without having to spend money on the engine every week.
