Another plugchop

[axo]

I did not want to hijack the other thread so here is mine.



How does this one looks like?
Someone mentioned i would need a bigger main jet, just want an opinion so i don't spend on different sizes that i would not need.
I did not put a 50 yet as baka suggested, but i wonder why the engine feels too groggy from standing, specially when it is hot.
Im still on 45 - 122
Thank you.

Looks good and a bigger jet would make it too rich.

I've also got the OKO 24 with a 46/120 and my plug looks a lot like that.
That's a little darker than "cardboard", and I sure wouldn't go bigger. Be careful going smaller, too. If it runs right when it's warm, the first time the outside temps drop significantly, the added air Density suddenly make your engine too lean. It seems counter-intuitive that cooler temps make your engine run hotter, but it's a fact. The few degrees cooler fan air don't nearly make up for the hotter combustion chamber temperatures of burning the leaner mixture.

If it runs well at WOT but bogs in the midrange a little consider putting the needle clip one click leaner and try that. (clip up, needle drops down deeper into the main jet...)

Please put your setup in your signature in User Control Panel.

Try a 48 pilot.that plug looks good.with the taiwan bore you want it a little rich.how many turns do you have the air fuel screw?

Ok plug looks good but believe me, the engine runs pretty much like crap... i still have the heat problem, only being saved by the castor oil i guess because is not seizing.
I will put marks on the throttle at 1/4 1/2 3/4 positions by looking at the carb slide opening accordingly so i can tell you accurately where is the point where i get the horrible bog down. still not going faster than 50 and i am a 130 pounds guy. I will go to my friends place and put it in the Dyno again to check the rpm now that there is no more interference from the sparkplug.

I was thinking of testing the low end to see if there is a leak, but if this would be the case, whouldn't the plug come indicating a lean condition?
My setup is listed on my signature. below.

Right now i think is is about one and a half turns out...

Put the 48 pilot in and open the screw to 1 7/8. Almost 2 turns. Try that. As for your speed,there must be something else going on. Mark the pulley with a sharpie to see how high the belt is riding.what brand belt are you using?

I can't say for sure but i believe i have a Kitaco kevlar belt by looking at an old list of a quote for the parts i got years ago from VT... the numbers are gone in it now, but i compared it to the one i had before which is a bando 23100-gg2-7500 and seems to be the same size.
So should i make a vertical mark with a sharpie on the variator and see if the belt erases it up to a point?
I also got a new Oko stock clutch with 2k green polini springs that i did not install on the scooter yet. Right now i'm running with the clutch and rusty springs i posted in this thread: http://www.hondaspree.net/phpBB3/viewto ... =4&t=16405

Ok i will order that 48 to see if i can get the temp a bit lower.

who can i buy jets from on this forum?

[bakaracer]

Your better off just buying the 10 pack of main jets. What brand bore is that your running?

but isn't the 122 main ok? why would i need a pack of 10 mains?

I am running a SHENG-E cylinder ( http://www.sheng-e.com ) State of the art craftsmanship and ultra high precision down to the atomic level cuts. If you want to "get there" you must have no other thing than a Sheng-e . Anyone out there with those Italian piece of chit kits should stand corrected and bow gracefully in defeat because the 11th commandment states "thou shalt not race without a Sheng-e kit"

When you changge that pilot.the overlap will make you main jet richer so you will have to drop down to a 120. Plus later down the road you will change your setup again or build another bike and you will have the jets already.

i see... well i am covered by now then... i have a 120 and a 118 too But next bike will be something like an R6 stock.. im not getting dirty again with this little toys haha.
Thank you Baka.

I'm with Baka on getting more jets than you think you need. In my tuning experience, you invariably end up needing the jet you don't have. Then you get to wait for Mr. Postman to get it to you, unless you go to Honda-san, who only sells packages of 4 of the same size for 3x the cost.

I'm truly glad you have enjoyed good experience so far with your Sheng-E cylinder. I hope your good luck continues. However trash-talking someone else's choice usually requires something more of a track record. Those Italian kits have been around a long time. This is the first time I hear of your Sheng-E brand. Time will tell how it holds up, and words are nothing more than that.

I guess i should have used the [sarcasm] put trash talking here [/sarcasm] brackets to denote that i was just kidding about it. Sorry if i hurt anyone feelings... it was just a joke.
