I have a pair of 250r's now; the white one is a midrange stock cylinder ported by RB Racing, 38a/s, and raised compression. I swapped out an FMF fatty I was running to a complete Sparks TT, and felt that I lost a good amount of low-mid performance. Mid to top, its a screamer now! I typically ride a mix of woods and open areas.
My second 250r (the red one) is stock bore, stock non ported cylinder, factory 34pj, fresh top end on factory compression. It had a rusty, dented old school FMF on it- I put the Fatty from the white machine on here to clean it up a bit. I'm going to keep this a woods/trail oriented machine; it feels much meatier in low/mid than the white one.
My plan is to keep the 34pj on Red, perhaps bore the carb out a bit, maybe swap the worked top end from White onto Red, so I can build a monster motor for White and turn Red into a woods beast. I want wheelie on command, climb a creek bank, hop a log without smoking the clutch power out of Red.
Will the Sparks MX be a huge measureable difference over the Fatty for Red's application? I would offer to trade the TT for someone's MX, but I may just keep the TT on White and build a beastly midrange big bore.
What do you guys' think?
