Just got a sweet 99CR adjed valves and belts all seems well, idles nicely, pulls hard . . .

Except, at light throttle opennings it constantly "spits" back through the airbox.

If I give it more throttle it pulls fine. It has Remus slips on it and I'm wondering if these have exaserbated a lean fuel problem at light throttle settings??

Any suggestions are appreciated.

yep, usual answer is .. Don't use light throttles.. they all do it.. use a different gear.

A 99 cr?? they're pretty rare.. the injected bikes started in late 98 and there wasn't a CR in that range.

Photos or it never happened...

My 99 900SS had same problem since I bought it in 2008. I did several things to try to richen it up but it did not fix problem. I finally brought it to Seacoast Sport Cycle and had a Power Comander installed and had it tuned on the dyno. I could not be happier! bike can now be ridden traffic without stumbling.

My older 95 SS/CR got a makeover when new with D&D's plus a carb kit with different piston lift springs, needles and jets. Ran like a clock. When one of the pipes broke a flange, I put the stock pipes back on temporarily, and Yuuck. Spit, popped, and you could smell the exhaust a mile away. When I got the new D&D back, put them on, and back to smooth as ever. So the pipes may indeed be open enuf for the bike to run quite lean. If it's injected, I'm lost.
