gripsters or irc 110?

On the same note, is there a way to adjust the Speedometer to reflect changes? Paulo Rodney Copeland wrote: I run a 4.60 18 rear on the front of Pam's Sherpa.

I'm thinkin maybe 5-7mph off. Rod http://pg.photos.yahoo.com/ph/zrod73026/detail?.dir=89ed&.dnm=a782.jpg &.src=ph

Hell, I don't know! Sure wouldn't wanna have to poop a new gear in the speedo drive. I always just figure I'm goin around 5mph slower than the speedo says. Does make me wonder if we can move the needle. I think I'll try it. Rod --- In DSN_KLR650@yahoogroups.com, Paulo Alves wrote:

Yep, you can, and Bill Watson showed you how on 12/30 of last year:

If it's that case, you might consider the IRC GP1. Anything more than the casual off highway excursion will quickly challenge the slipster. Low end of tire life for the GP1 would be around 4500 miles and the high end is around 6000 for the rear. Pat G'ville, NV
