NC23 RRJ Carb Qu
Quick question from mechanical numpty....
Got a monster flat spot at 12k.
Bike runs standard 4-2-1 (well a delk copy) downpipes, Standard RRJ airbox. Newish standard air filter & straight through race can.
EDIT: blah.. blah...blah...
I know nothing...
Cheers

Re: NC23 RRJ Carb Qu
running better when cold says it is too rich... so is your filter clean? what jets you got now?

Re: NC23 RRJ Carb Qu
Filter's clean, Will check on Jet sizes when I get some float bowl gaskets (the ones on there don't look great). Given it had individual foam filters & a slightly more restrictive exhaust when I got it ...
Any ideas on a good size to start with?

Re: NC23 RRJ Carb Qu
easy way to tell if your rich or lean....see if it pulls thru the flatspot cleanly if you roll off a tad,if it does,its lean.

Get it done on a dyno so the power works right through

132.5
Rich or lean question answered. How was I living with that?
Sorted spectacularly with a suitable set of jets from Graham France.
Cheers Graham.
Dyno's on the to do list for curiosity.

Re: NC23 RRJ Carb Qu
132.5, bit big eh?! What size did you get from Mr F?
I recently discovered my carb had 102.5s, so I got a set of standard 105s (K model) from the man. Since I have restrictors and a straight-through can I don't really know what size I should have, but I don't want to be running lean - will get it on a dyno soonish.
Am I right in thinking can = upjetting, restrictors = downjetting?
