A 562 Pound Pile of a Sorry Excuse for a Two Wheeled Vehicle Wussy ride. As uninspiring as riding my couch. And A Corporate Idiot actually is going to try to Market these in the US? they would be on the sidewalk with a cardboard sign if they were that clueless to the Merkin Market and worked for me. Who would be seen on that pile in the US? And there again some actually purchase a CUBE for a four well vehicle. I suppose they would be there market a Cube for a Four Wheel vehicle and a 562 Pound Couch for a Two Wheeled Vehicle. That to me is a automatic motorcycle rather than a scooter, and for what, roughly 12 grand when they get done with you? There is a guy that works at a local grocery store here in Palm Springs that just bought a beautiful Yamaha Bolt V-twin at almost 1000cc for a little over half the price. Exactly!  I didn't even pay $12,000 for my 2012 CBR1000RR |

HMMM...
In marvelous contrast, my "new" old '04 Accord UEX will easily top 160-mph (taching less than 5,500 rpm) and I must admit it's SWEET when necessary, to run with the bozos cruising at WAY over the century mark... She IS shod with new Michelin "W" rated meats and has monster ceramic brakes. It AMAZES me what Honda sold through performance stores back in the day! Let alone FINDING one with low miles and restored to factory-new condition! Care to inform the Kiddies How Your EX does some 30 mph faster than any other production EX? Taching Less than 5,500? Uhhhhhhhh she Ran Out of Snots Choppersquid.Not enough to Pull Top Gear. And being from your hood what section of road are you doing a easy 160mph? 114? 170? I-35? Roanoke Road, lol Or is this another Grapevine Lake Fish story of the HD Bobber doing 10's @ 135mph or so with Semi knobby Tires and OompaLoompa at the Helm? Or was that 8's on a Shovel or Pan 150ci ? Educate us. |

Valve Seals Wont Wait for the Engine to get warm or Hot to Puke oil, Missing or Junk Valve Seals Normally Show up as Smoke when you Wack to wfo then throttle chop off. Vacuum Sucks the Oil right past the seal.
Also Overlooking, He indicates its Hard to Start unless Throttled, then She Smoke when up to Temp, Classic Clapped Out Top End.
Yes the Second and The Oil Ring itself do control the oil but the Piston must keep the rings Square while traveling up and down the bore.
So ya a Ring Job Most likely will bring back some life but that life is very short lived when its paired with a Clapped out Piston and Cylinder Bore. Going this route you Must measure your Piston to Cylinder Clearance then run a Dingle Berry Hone to Break the old Cylinder glaze.
Most Don't Possess those tools at home or the experience to properly use them.
Unless you must get to work or wife to the hospital throwing a ring in ended a long time ago.
There are couple few ways the Ring is Junk, Trash going thru the Motor and Heat. If its the most common Trash going thru the motor, just think the Top Ring is Stainless, So if trash junked out the ring imagine what that Trash did to a Aluminum Piston and Iron Bore?
These parts are so cheap so why do all that? $75. for a Brand New Complete Cylinder Head and a Brand New 58.5 or 61mm bbk complete with Gaskets, Piston,Rings,Clips and pin. Bamm! Done!

What do you mean by "Cam Ratios"? I'm a sbc type of guy and have only referred to Rocker Arm Ratio's or Rod to Stroke Ratio's. Maybe just some different verbiage, I've never heard of a cam ratio. I haven't seen any alternative Rocker Arm's with different ratios on the market, would be cool to get another 10% Cam from just a Rocker Arm Change You know how the cams can come in 3 levels (I call ratios) Low rpm torque/low lift - mid range torque/little higher lift- then the good old muther thumpers (as they call them now) Saturday Night Specials Very top end torque/very high lift. Yes I know about setting the right cam up with the degree wheel etc etc. But I have always asked people what they wanted. Low- mid or top end. Then work around the weight and gear ration to get what they needed. Shoot the Pontiac Sunbird and Chevrolet Monza (Wagon) both weighed in under 2900 lbs so the power to weight ratio was fun to play with. I ran a 2.53 rear gear and would drag race out of the hole in second gear (Saginaw 4 spd). I would pull the Mustangs out of the hole while they changed gears 2 times (1st-2nd into 3rd) I was still in second walking away lol. Just old fashion fun. "You check your hawg head lately?" lol I would get people with that one. Heedehcheenuh Chuck D Ride on..... A 2:53 gear Leaving in Second of a Saginaw Slush Box? Are you at the Salt Flats or Talladega with that Gearing? surely Not at a Drag Strip. At the Strip? What do you measure your 60' Foot times in? Days or Weeks? |

Did you do anything to the Scooter (tuning/jetting) to think it is Rich?
or What makes you think its Rich?
Another thing to consider is the Intake Charge of Fuel acts as a Coolant When it Enters the Cylinder, Your Not going to Melt Anything Down if it gets Too Much Fuel.
This is a Fixed Jet Carb so not much on all on its own is going to make her go Rich. Running Rich and Hot should Not go hand in hand.
Think of the Bunson Burner in School, On its own the Alcohol flame is Yellow Now Add the Air Hose and you are Leaning its out and the Flame Goes to Blue or White Hot,
Good luck

Your Air Filter is Clogged........ Clean It........or
Factory Jetting should be sufficient unless Someone else Changed that?

Speculating a GY6-B engine . . cylinder stud spacing is different from typical GY6 engine.
Concur there may be a piston ring blow-by issue.
Might also verify that a deficient vacuum fuel petcock diaphragm is not allowing fuel to bypass the carb.
May be overfilled if checking oil on sidestand or centerstand. I always check mine as the bike is ridden, both tires on ground, straight vertical. Did you do the leakcheck with the engine hot? Worn valve seats can seal at colder temps and open up at higher temps, allowng oil from the top end into cylinder... If my Valve Seat is Clapped Out How Does that Let Oil Into Cylinder as you state? |

Electric Impact www.harborfreight.com/12-in-heavy-duty-electric-impact-wrench-68099.htmlThese are almost always on sale from a weekly flyer for $39.00 and they Always have a 20% off coupon you can use on top of that. I own one and She has some Snots. Other than anything on the scooter, Car and Even Big Blade Brush Hog 1-1/4 Nuts. That dude in the video is a joke, another squid just providing misinformation. barn yard butcher with a pry bar. Both my USA made Chicago Pneumatic or Ingersall Rand will Shear the end of the Crank off with Nut Impact if I wanted to. The Electric impact I'm using is Overkill for such a small nut on the end of the Crank, I'm more concerned of busting it off as this Impact has no adjustment as I do on conventional air |

Instead of simply tossing a tire because of a date invest in a Durometer. it tests Tire Hardness. I have had these for years, I even use it on all my New tires then note the hardness. The tire will go hard long before you ever see that dry rot.  |

OK I hit a wall ... sort of. I have done a few runs and she has maxed the torque and speed at 50-53 mph (GPS) up hill around 7000-7200 rpm. Do I need more air / fuel / or both? Lets say stock is 24mm and I am looking into the polished intake with a 26mm-28mm (not to large) carb to get more air and both carbs can be had with jets to richen or learn her out (I prefer rich to save motor). Also what is up with the cam ratios?!?! I know small block Chevy cams- heads-intake performances but I am new to the scooters lol. I know the gear ratio will be best for the BBK in the future but right now I am looking at carb / intake / air filter to change that will work with the 150cc and be adjustable with the BBK in the future. I have been down and out for over a week now (R.A. has kick my butt big time) from my left knee and leg being swollen the size of a volley ball. The motor is sill not broke in yet , still under 500 miles, and I want to ride ... so bad. The weather also has been picking at me but hey that happens living in the south east. Heedehcheenuh Chuck D Ride on..... The GY loves to breath easy, the stock airbox is Not restrictive as it Far Outflows what the engine can use, its just a velocity killer,. So for what it seems Your looking for pull the Pollution crap and block it off, throw the Stock Airbox away along with the Vacuum operated Fuel Pump and Capp off all the Vacum ports you won't be using now. Then install a UniFilter and Re-Jet for nice results. Polishing on the intake side does the same in any engine, Nothing but look perty. You Scoot sounds quite I dunno if you have a stock fart can or aftermarket? Also right now check your Belt Climb, If your Not getting proper Belt Climb you loosing top end mph, just draw a line with a Black Sharpie and the belt will wear off were it rides and leave you something to measure. ok my pictures aren't loading. What do you mean by "Cam Ratios"? I'm a sbc type of guy and have only referred to Rocker Arm Ratio's or Rod to Stroke Ratio's. Maybe just some different verbiage, I've never heard of a cam ratio. I haven't seen any alternative Rocker Arm's with different ratios on the market, would be cool to get another 10% Cam from just a Rocker Arm Change |

This Has happened every time at 80-  % throttle and above the engine is at its Hottest point. Especially indicating to you was the first time it happened you were at or near WFO you "Chopped" the Throttle, A Throttle Chop especially at Near WFO causes the engine for a brief period to go Lean, Lean=HOT, Exhaust lash closes up and Boom she dies. The Exhaust Valve Lash (Clearance) is Closing up to Hanging the Exhaust Valve Open then she dies. cools down bit and fires up and drive away. When this engine doesn't start the fuel is going to go somewhere, its simply puddling indicating a leak. If you have 450+ miles on that Scoot you are Way Past the Point were you should have Adjusted the Valves. Your symptoms apear to be classic text book too tight Exhaust Valve Lash. I have never seen one come from the factory that the Exhaust Valve Lash was Not too Tight. it heats up, expands then won't completely close. Its a easy process, just look up some tutorials and Quadrupple check your work. Good Luck. |
