RS Flat Slide Pilot Jetting

They look rich

Maybe. Was peanut butter color before the change.

at o to 1/8 throttle run lean .do not let the motor load up .thats the problem i had .with the cams and the higher comp . pistons .the plugs would foul out .i could not let it ideal so i change the air jets and pilot jets.

Lots of variables to consider and work through.

Do you have hot cams and other HP items? If not that doesn't apply.

Not sure how "hot" 84 GPZ head (ZN technically) and camshafts over stock pistons make the engine, but there certainly are more things to play with on the RS carbs, vs. the BS 34's having fixed needles and air jets.

The motor seems to run cooler than it did before. :S

Is it the color that makes them look that way?

The images show more gray color than the brown/tan I could see on the insulators. My camera just wouldn't capture that detail as I wanted, but do seem to show the plugs were burning well.

I've since changed spark plugs to NGK BR8EVX (BR8EIX predecessor) Platinum, which I had used in the engine a couple years ago. I got a couple sets cheap on ebay, so back with them for awhile, and swapped plug caps back to the non-resistor type.
The engine does start easier, and runs smoother with them.

A split decision? :S


I wonder :woohoo:
Thinking about the competition baffle again :whistle: , since I'm pulling more air with pods now...perhaps no baffle at all :ohmy:

I still have my competition baffle in. Yet to try the street one. I repacked it ans it works well. Try no baffle. I'll bet that won't last long. :evil:

Kept displacing and blowing holes through the packing, and I hate handling the stuff. That crap is gone, dude! :evil:

Back pressure is your friend. I'm going to try the street baffle without packing. My Jardines didn't have any. The drag baffle was a drag :lol: .

Hi all,

A bit of bizarre info on exhaust tuning....

There is a You Tube vid on a shop in Australia that made a big block CBX that put out 165 RWHP (dyno'd). That is impressive enough, but they also ran a stock ENGINE CBX chart for comparison, and got 123 RWHP (with bigger carbs and other tuning mods, but the engine internals were all O.E.M. Honda)!!!!!

N-F-Way!!! Many commenters started calling them out / B.S. on that one, as a very respectable stock CBX is generally thought of as a MAXIMUM 89 RWHP engine - which matches about the best I ever got from my stock CBX's. In fact, it is near impossible to get the big six out past 100 RWHP without going 1155 cc, nitrous, or turbo. Turns out, as they claimed, that much of that 89 to 123 RWHP gain was apparently from tuning the exhaust - the critical parts being the length of the head pipes, collectors, even the straight pipe section from the last collector to the mufflers, and the mufflers themselves.

Trust me, I am very willing to try playing with exhaust tuning if I can gain that kind of power increase!
