Chewy is on it again. he is correct on this. I was looking past the BBK and was thinking a Pipe and intake Mod to compliment the BBK. My bad.. Really? I thought a bigger cylinder 125 to 155cc is gonna suck in more air and need bigger jets. Unless the increased air flow is gonna suck fuel through that stock main jet faster. Confused now. The CV carb is very forgiving. you have added No cam or Exhaust. With the BBK as the only Mod you will get very little and next to nothing in hp or torque. Your stock head pipe is a smaller diameter than your exhaust port. were just getting closer to flushing a toilet into a Cocktail straw. If ya want to get any benefit of more displacement its a total package, Exhaust, Intake, etc. |

Do i need a pcv valve Ordering parts and i wanna know if the head has a pcv valve in it where the breather hose comes out. I wanna delete the breather hose in the airbox. Do i need a one way pcv valve to put on the end of the breather hose? Kymco 125 You don't have to have one but you if you don't you Must run a Catch can. Run the hose up high and stick the end a catch Can. I tried running two of the Valves from Scrappy and just had a Epic fail. The Valve I had on the Valve cover hose just seemed to start not letting the Crank pressure to escape properly. then you know whats next. With all that crank pressure built up on a 7,200 rpm run the second Valve I ran is on the end of a hose from the Oil Dipstick hole. I saw a few drops spew as I looked down at my tach then she puked a good half quart of oil all over the Floor board. When I went to put oil back in, geting close to full the oil was filled to the top of the fill hole. I have a Measurement funnel to put in the Correct amount, so I new I wasn't overfilling. Then I heard a squeaking noise coining from the valve cover pcv. Boom that was it, I just run that hose in a Clear catch can for now. Good Luck. |

Oh, my bad, I did fail to address your question "is rotating machinery dangerous" The question is so general itself its a no brainer, unarguable fact, Potentially, Yes. potentially, as in "it depends", right? running without a cover is entirely your choice, but there could be some obscure laws on the books in the various states that might prohibit it. i know machine shops can be given hefty fines for running lathes and such without their covers. Did I stutter? lol just jackin with ya buck&quarter.. "it depends", yes, correct, sure.... depends if I have a five foot long leg that can bend around and under my Scoot like some acrobat with some 16" shoe laces dangling.. If there are any laws there never going to be enforced, look at any HD with Pipes, on the pipe they all say "For Off Road use Only" nobody enforces that not even the emission/safety check thing I had to do in Texas with my bikes. OSHA these days keeps legit Shops in pretty darn tight order these days. |

Well ol Buck and a Quarter, I went out again and sat on my scoot with my ankle biter and have to do some Cirque de Cile contortions to get any part of my body over and under the bodywork to get a toe in my faceless vary.. just not realistic. yes, the variator is somewhat protected by the floorboard. my main concern is the clutch. secure some long leather thongs to your belt. then do the hula in front of your clutch. keep in mind the scoot is probably idling and producing nothing near its rated output. some don't. and i bet almost all of them was due to someones negligence. BTW, you failed to answer the question of "is rotating machinery dangerous". Oh, my bad, I did fail to address your question "is rotating machinery dangerous" The question is so general itself its a no brainer, unarguable fact, Potentially, Yes. I again with nice weather retuning got on my 150 ankle biter in the riding position at a stand still, I not know how long your legs or your what? flexibility or something can get your ankle back to the clutch, Then I tried this acrobatic or aerobatic act while actually riding and my foot is like 14"-16" away from the clutch, just not realistic to condemn as said. On the Farm thing from experience, not the negligence it was more often then not complacency, I was guilty of it myself at times as a young Punk, it was very easy to fall into when that was everyday life.. |

Hello new to scooters got the kymco agility 125cc small wheels. Wanna get a big bore kit to use with standard carb standard cam amand standard head What main jet and pilot jet should i start with? The standard main jet in my 125 has no numbers or markings on it. No idea what it is. Been researchig alot and not much info on this. Looking at this one but dont know about the quality maybe someone can tell me about the quality. Because of my location in its the easiest purchase option. m.ebay.com.au/itm/Power-Big-Bore-kit-58-5mm-160cc-Kymco-Agility-People-125-Like-125-/322195354306Something just caught my eye while checking out the link to the Product, The Scammer claims 160cc's The Thief must have Flunked out of Kindergarten math. Pathetic.. I knew of the top of my head that +1.5mm or a rounded .060" Does Not Add 10cc of Displacement on a single cylinder.. The Actually Displacement comes to 155,356cc's darn near a whole 5cc short of there claim. Also there is Nothing "Race" about there junk.... Run from this type vendor! |

Your not going to get any takers on the Jetting bro.
There are too many variables to have a cut and dry jetting for all.
Do your best research on the Stock Main jet size then Purchase the next Few sizes up to get started.
Same with the Pilot Jet, purchase the next few sizes up.
The total packing will most likely require a Pilot, a Needle Clip position and a Main Jet change for optimal performance.

What kind of (brand) of Two Stroke oil are you using?
And are you Pre-mixing or is it Injected?

I suppose under your odds there is no way I should have survived my dues paying years in the equipment business,
So you go ahead end enjoy being curled up in the fetal position in the corner shaking like a Chihuahua 24/7, Im going to go Ride,Race, Dive and Shoot.
Remind me of some ol bitty shaking her finger at me that I need to get off that dmn motorcycle thats no way for a family man to act, or the current crop of Whiney arse NASCAR drivers.

.7854 X Bore X bore X Stroke=cc's .7854 X 50 X 50 X 41.5=81.485cc's To correctly measure the Piston, measure at the Bottom of the Piston Skirts  degrees to the Wristpin. ok excuse the emojie dude I can't seem to be able to edit it out. Theres is No Such thing as a Actuall 100cc kit for a GY50cc. The Scammers are just "naming" the kit so. The math don't lie. |

I'm afraid I have to interject myself into the foray,,, I'm in the camp that more than half of the lawsuits involving moving machinery and injury was actually caused by the " victim/ injured",,, by getting themselves into moving parts of a mechanism,,, common sense says don't doit but done anyways,,, who's at fault? well yes cyborg, the victim gets into the machinery, and it's usually an accident. how in the world do farmers fall into their own PTO shafts? or get run over by the tractors they are driving? it's really easy for me or you to criticize people for getting stuck in machinery BECAUSE WE KNOW THE DANGERS. once you realize that you aren't supposed to stick your face in a fan you understand that. i really don't feel like arguing the point anymore. if you want to imply unprotected rotating machinery is safe, then you go right on ahead. i'll be the first to step to the plate and say, YOU ARE DEAD WRONG DUDE. how can someone get hurt by your open faced CVT? before i put passenger pegs on my scoot, my passenger had to used the muffler for the right foot, and the CVT case for the left. i can just see their left foot slipping off. the perfect scenario would be their pant leg gets caught, makes a half turn of the clutch, then gets spit out. the situation gets progressively worse the baggier the clothes to where flowing dresses can cause you some serious injury. would you really mow your grass with just an engine and a blade? Farmers don't Fall into PTO shafts they Step over them, and wrapped up they get.. None of your scenarios apply to me, there pretty darn silly and unrealistic in all reality. "flowing dresses" In the Western Carib a Sunday night at the Plaza with all dressed in there Sunday Catholic best dresses there are none that come anywhere close to the CVT baggy or other. Do you even change your own flat tire with the risk involved?  Mow my Lawn with just a engine and a blade? heck ya the finest mow you will get is a Reel Mower, not much other than a engine and a Reel or Two or more of open Spinning Reel Blades. |

I'll chime in here and side with piston yet again,,,it's either the pads /bell glazed or a spot or two of grease/oil got on the swept area of the bell and is pulsing when the pads sweep thru the contamination this thing happen only on the first take off, when the engine is warm there is no vibration, i'm afraid it may be the piston because i do a complete service on the transmision not long ago and the day before i have this problem i may drive it to rough because i was in a hurry to get to work The Clutch, Belt and Vari are all Cold, they will make a extra squeak or two when Cold at take off. Mine does. Remove cover and service. Your dealing with Pistonguy here Ill let ya know if anything sounds like a Piston problem. |

Sounds like your Clutch is "Chattering", The Bell and Pads are Glazed, Simple Service should fix her.
