Title: RC51 gearing for Midwest tracks
Post by: tigerblade on February 19, 2003, 06:10:44 AM
Right now I've got 15/41.  I'll mostly be running at Gateway, MAM, and hopefully maybe Blackhawk.  Any suggestions for these tracks?  TIA...   ;)

Haven't gotten around to trying any gearing changes. I was going to start with 15/40. 15/41 will probably work pretty well for those tracks, unless it causes some bad shift points.

MAM is the only track of those I've been to, and the short straight between 4 & 5 was the only place I really redlined.  If I went up a gear it was just for a moment, so I usually just redlined it there.  Getting rid of the soft limiter might address that, but I also plan to be going a lot faster than I was.   ;D

Disconnect the soft limiter.

A 15,16 front, 40,41,42 rear should be a good selection for the RC.

I've already got the wire to defeat the limiter; it'll be done soon.  Thanks for the gearing advice.   ;)

I put ss lines on immediately after I bought it; will be replacing pads before I hit the track.

The rider is the one in need of major dieting.   ;)

Rotors will have to wait.  I've got too many other things I need to spend $$$ on first.  Thanks for the advice though, I need all I can get!   ;)

I suggest going with the 9/66 gearing so you can do wheelies with the giggleheads.   ;D

I'm doing trackdays at VIR April 21-22, not getting back until the 23rd.  Don't know if I'll be able to make another long drive to WI that next weekend.

I ran AM Supertwins last August at RA and won. 15 front and 42 rear. Stock chain just a bit shorter on wheelbase. I hit the RPM max on the home stretch but only just before the pit exit. I don't think it hurt my time much. The RC is geared tall to begin with. This year I switched to a 520 chain with 15/41 gears and new exhaust and PCRIII and marchesini cast rims. (See my post on RC woes) I desperately hope to make it to RA seeing that I pre-paid and all. Hope to see everyone there. I pit near the gas pump.
