I recently got married & had to sell my 2010 crf250r before the wedding to help fund it. Well, finally the honeymoon is over & it's time to get my moto card back. I've been saving my coin & am starting to look for a bike. Just a little on my background, I'm 33 & grew up on 2strokes. I had a few rm125s & a 96 cr250 which I loved. I stopped riding for 6-7 years & when I came back onto the scene 4strokes were the thing. So out of the past 4-5 years I had a rmz450, kxf250, crf250x & my recent crf250r. I ride woods 95% of the time. I love the woods & bikes set up for the woods. I love 4strokes to, I feel I'm a lot faster & smoother because I feel confident on them. I recently rode my buddies 2010 250sx. We just kinda went out & messed around on a little outdoor single track loop we had carved out. It's been so long since I've ridden a 2stroke, but it wasn't as bad as I thought. I felt pretty smooth & with some saddle time I feel I could get comfy. I like to race a few harescrambles & a GP here & there. I've always noticed a lot of the guys that are on smokers run YZs. So I got to thinking I could pick one up at a decent price & put some coin into it to set it up nice for my style. My question is, what are the good years (04-06?) that are good for an offroad base set up? Which had the SSS & why is it so good? What fly wheel weights are guys using & how does it make the bike feel? What all can be done to smooth them out & be tractable for off-road? What's up with adding the triple clamps on certain years & I guess any other knowledge I can learn about this bike. I've seem a lot of 04-06 for good prices & that seems to be the good years from what I've heard. Switching to 2stroke is a big choice for me, so I just wanna make sure there's a lot of dialing options that will suit my style. Thanks in advance for any advice.
