[QUOTE="DrZero, post: 1151432, member: 51405"] 1. You stall more in the woods. It's inevitable. Trail surprises, too tight turns, logs you don't make it over on the first try, other riders. 2s start right up, even more so when hot. 4s are hard to start when hot. Nothing worse than a dead bike 3/4 up a hill that won't kick over. Thus the popularity (requirement) for a button on enduro 4st. I haven't ridden the latest and greatest 4 strokes which have hot start dodads. But I bet I've spent 20 mins trying to get my other two four strokes started in the past. (See 1st post of mine that started thread for details) 2. Weight. Bad. Again, new 4 strokes are getting lighter, but it's really the pure MX ones (no button) that are close to 2 stroke weight. And even then they feel heavier due to more top heavy design (all those cams and stuff on top of motor vs. one little spark plug on the smoker), more reciprocating weight (spinning stuff is a gyro). 3. What your used to. 2stroke guys think 2strokes are easier. No engine breaking so the rear brake is used. Rear break a 4stroke and you stall at, at which point you hope you got the heavier one (even on a steep hill) because of point 1. (4stroke guys think four strokes are easier!) 4. Hit. I found all three of my four strokes lacked it. The 300 was gutless in the extreme. The 350 was actually the ballsiest of the three 4 strokes I've owned, but the 250 2s kicked it. Snap the clutch, wheelie. That's way useful on trails. Somone here says they like the 250sx best for trails for just this reason. Again, I've looked at the power curves on the new big-bore racing four strokes, this does not appear to be much of a problem anymore given they may big power all over. My DRZ know has some decent snap (14/48 gearing) but can no longer do an effortless 65mph, thus removing one of the cool reasons for buying it. 5. Failure mode? This might be me but usually when a 2s has problems it just starts running ****ty, but still runs and can get you back. Everytime I've been stranded DEAD it's been on a 4s. The failure modes tend to catastrophic. (Total tranny lock up on KLX. Total dead battery on DR (no one in my group carries jumpers on in their butt pack.)It did fire up back at the truck. And this after it showed perfect charge in the AM. ) Nothing sucks more than pushing a bike over a trail you'd like to be riding on. [/QUOTE]
