Hello, I was hoping someone could give me some tips on slowing down my bike. My son just started racing motocross, so i thought id get a bike to ride to. I havent raced since 1991 so i thought id give the vet class a try next year, So i bought a 05 crf450r. The bike is to fast for me right now and id like to slow it down. Its got a lightend fly wheel, 13.1 compression, full big gun exhaust. 13-48 gearing. The bike came with brand new gears and chain, which i just changed. The chain was cut to fit the 13-48. would going to a 12 tooth up front stop this thing from wheeling or go up in the back gearing. It really lugs down in slow speeds in 1st. 1st 2nd and 3rd it wants to flip over backwards lol. Im not new to motorcycles or broken bones but id like to enjoy getting back on a track but this bike worrys me.
