Loving that this thread is turning into MX nerd talk. @moneymoneymoney my front tire is in good shape but when it comes time to change I'll be putting an mx33 back on. Fave front tire so far.
Bike has about 180 hrs total, but had a full rebuild at 115, and I'm doing the top end within a few hours. I can get a good amount of hours out of a piston since a lot of my riding is low-rpm enduro type shit. Suspension is valved for my weight and riding style.
Next big mod is putting honda brakes on the front. The stock brake is so squishy, no matter how much I bleed it. Kind of crazy how much better Honda's brake even though they're both nissin systems. Got a caliper and master from a crf450 on ebay for $60, should hopefully bolt right up.
