Title: PA owners need carb help . . .
Post by: Postal on July 21, 2005, 12:38:12 PM: Ok, i have to rebuild my carbs. The bike hasn't run since 1998.

What jets do you recommend?

What should the float be set at?

The screw on the bottom of the carb, how many turns should it be set at?

Plus any other recommendations you may have.

Thanks in advance.

I have often thought the same as Oxford till I did a Yahoo map search.

Martinsburg is about 15 miles south of Altoona.

Basically I am going to keep it stock for now, except for the air filter. That foam piece kind of fell apart when i took of the air box. I will be getting the K&N air filter in its place.

According to my manual...

102.5 is stock on the mains
32.6 is stock on the pilots
14.6mm
1 and 3/4th turn from lightly seated

From my experiance the K&N in of as itself doesn't require a rejet, since the real restriction on the air intake is the tiny little hole the airbox breathes through.

Good luck!

As anyone who has read my posts here will attest to, I am not a carb guru. I do imagine that the K&N would make stock settings pretty lean. In particular, the infamous 4K flatspot might go from annoying to nasty or somewhere in between. Maybe up a size or two on the mains and/or add a shim to the needles? A/F screws maybe out a little from their 1.75 stock setting? That's probably where I would start but I've been screwing around with my carbs for a year now and they're still not right so... I'd put it all back together in stock form and see how it runs before messing with it.
