how so? (honest question)
I think spending less applies more than saving money.
I can think of a few ways,
-run stock motor with pump gas
-use tires until shot/sell scrubs
-few sponsors don't hurt
-learn to do your own service/set up
-avoid expensive canopies/trailers/tow vehicles
-lose weight(saves fuel)
-cook meals at track
-dont drink beer
-stratigically plan your race entries, so you never get bumped to expert, and never have to worry about riding very fast/challenge yourself
-dont crash
-use stock parts if possible, until aftermarket required from damage etc
-do not ever allow your girlfriend to get a race bike and start racing(doubles your costs)
-get your mom to come to the track
Seems spending money won't really make anyone fast. I've spent a lot of coin this year, a lot, and I'm still just an average rider.
