RE: ENGINE??
Well said aangelet (about running stuff you can afford and having fun).
If I had to pay $300 for a mill I would be scared to run it hard. Instead I'm now running the TTR PRO and it is a very good performer. I think I cooked it at the last race and it's not much to cry over (pressure line came off). Cheap parts and cheap to replace ---> more fun.
I just happen to have a new C6BB waiting to be installed. I won it so I didn't pay $360 for it. If I did.... I'd be more careful and having less fun because of it.
