This spring, I'm going to have a real hard time not buying a 250r. In times past, I've had an '89 cr125, '91 Suz DR250, '91 RMX250, '01 400ex with the usual goodies, '03 cbr600rr, and an '95 f150 4x4 that I had a 393 stroker built for. Now my only toy is an '05 Kawasaki ZX10r.
I really like all the new 450r's-especially the new Kaw coming out, and have ridden the yfz, but I really don't wanna spend all that cabbage when new stuff is always going to be coming out.
NOBODY around me rides a 250r. I want one for that reason, because they handle great and are light, and because they seem to be debateably just as good or better than the new crowd with TONS of inexpensive aftermarket! I look on ebay everyday for '88 or '89s, and I really want one that is somewhat close to original and hasn't been all cocked up. Haven't had the chance to ride one yet. Ridden a couple of Banshee's...lightswitch power with conestoga wagon suspension. I rode mostly woods and trails, hills, rivers, fast blast on open fields...not too much into racing.
I've been reading a lot about them. A couple questions. How big is TOO big for a RELIABLE, all around powerful motor on premium gas? I've heard a lot of people say the 310 range is that balance due to not having to bore/split cases. Seems 265pv motors are very popular for everything. ESR, Sparks, LRD, CT...what are some other good kits/builders? I understand porting plays a huge role with a 2 stroke depending on riding type, but does the porting have to be matched to the type of exhaust as well? Say I got an R in good shape and got a top end kit for it. Is it always a good idea to go thru the bottom too and replace seals and bearings? Keep the stock crank or go HotRods? Will a properly jetted 250r that has good top end and compression foul plugs like a madman? How long does a good top end last for, and do you have to bore/hone each time, or just inspect bore diameter/roundness and re-hone/replace piston and rings? Do you have to go thru the bottom end each time?
Sorry for the long post...hope I don't sound like an idiot, I'm actually pretty mechanically inclined...I've been a Journeyman Machinist for 9 years, CNC service, and most recently Application Engineer and have always worked on my own stuff so far.
Hope you guys can tell me some things I don't know!
