1 theses bore x stroke combos get a little odd to make the engine match the weight. these engines will be built from scratch and not parts most ppl already have. so that go against affordable
2 how do i even know just what the build will weigh before im done with it to pick a engine size. so i guess im gong to have to over shoot what i think it will weigh. it will easier to add weight when in done?
3 affordable class but allows carbs and standalone??. most ppl have the piggy back stuff and if not it can be bought used cheap.
lets look at from an engine builders standpoint that wants to back a bike in the class to sell engines.
under rich's rules im going to put all my r&d into 2 engine combos 1570 and a mountain motor. i can try to shine with these engines. it will be very difficult to be great at every engine size. just like if im running nhra prostock car and i want an engine ill call cagnazzi, if im running adrl prostock ill call sunny. i just dont think in the long run the 2.62 rule will help the class grow
im pretty sure im not going to build under these rules. i think it will be short lived
