CB350, Not Quite Perfect...

[cjdisaffected]

Thanks again for all the advice Barnett.

At this point, I am just trying to find that last 5mph at the very top end on highways. As for the bottom, it's pretty close to perfect there, and probably a good idea for me to run a tiny bit rich rather than lean to help manage my engine temps in the city (where I ride most). And, yes I completely forgot about weather. If I dial it in perfectly now, I am just going to be rejetting come September.

no prob, you're welcome . . on thing you might be able to do to get more top end is increase the ignition timing a little if it is adjustable . . if it has a mechanical advance you can modify it slightly and try it . . this is something that few people think of, but i build high perf engines and am a tuner, and i have done it a zillion times.

if you hear a light pinging sound on acceleration, it has too much timing for the octane you are running.

going back to the points as well the only ones that work without issues are the oem honda or jap made units, the china ones are crap they have way too much clearance on the post that they pivot on and it allows for erratic timing and barnett you need to shut the fuck up and quit mouth defecating, crazy pj knows more about carb tuning than you, alot more

Lol. Xb33. Both Barnett and PJ have been a big help here and I am sure that Barnett knows that PJ is the fucking Pope when it comes to Honda Carbs.

The points are Daiichi and have less than 800 miles on em, but heading back to the timing is definitely worth a shot. I have not checked in a minute. This is my last tuning weekend before my trip to The Dragon next week.

You don't know the first thing about me and his comment about the pilot jet not adding fuel at wot proves that at least in this particular area, he obviously does NOT know as much about carbs as I do, however, this is not to imply that he doesn't know anything and I'm sure, just like I, he too has helped many people help get their bikes going, plus, at least he and I are tying to help CJ to the best of our ability, but I fail to see how your comment will help him get his bike jetted . . I guess our method is just different than yours.

barnett you need to shut the fuck up and quit mouth defecating,...

LOL...and you need to go back to watching your Broke Back Mountain video by candelight with your dog and your Vaseline.


Oh man...that's nasty!

You obviously know very little to nothing about Honda 3 jet carbs 8)
As I previously stated, the pilot jet is fed from PRIMARY MAIN JET through a cross drilling so CANNOT add extra fuel above the limit set by primary main.
The discharge through pilot outlets (and bypass) is still limited by primary main unless you remove the blanking plug above pilot jet (which REALLY messes up fuel delivery)
I hope that is simple enough for you to understand? (if not I'll find some pictures : )
Fuckit, here's a picture anyway

This is a 360 carb but 350 is mostly the same.
Jets are held in differently on 350 and pilot jet has a 'rubber' bung instead of a screw in plug
You can see from shape of casting where the cross drilling is, blocked with a brass ball (lower right)
