Graeme Brough had records from my 98 yz125 he did when he worked at Fmf. Found that out when I was having him revalve one of my sons bikes bikes in 2011ish. I was shocked when he opened up an old notebook and showed me.

We owned many crf250s over the years mainly used for racing moto and big6 Gps... If I were looking for one I'd find a used 13 and restore it . That chassis/motor package can be made to work phenomenal.

Agreed on the 13..my sons was very good after a few mods...

Not sure if youve seen "invaders" out at Spangler or if it is any bigger / better than anything at jawbone cause I've only been to jawbone once but spangler is loaded with some really cool canyons with tons of hillclimbs etc. Fun times out there for ... more »

Only way I would even consider that deal if it was no more than 5k and it was taken care of and in fairly good shape. That's taking in to consideration of me doing my own work and getting parts cheaper than most. Imo it's not a good decision. My son ... more »

This right here^^^^.....I let mine heal on it's own. It was a clean break , snapped straight up into almost "teepee" position. I'm glad I didnt get surgery and it healed fine. I have no issues from it at all.

It's crazy the thought process of those because a piston / gaskets can be had fairly inexpensive ($150ish). Imo that's the only "major" expense at 30-60 hours and a motivated person can do the work themselves rather easy.

Exactly...case by case scenario when buying used.

Precision concepts did amazing job for my 140lb son on his 14 crf450r....Gp settings btw.

Interesting you mention grades, chores and working out. My son gets excellent grades, comes home from school, does chores, homework and elliptical. We gave him a choice of choosing a sport, motorcycles, mtb bikes, etc, something physical, whatever he ... more »
