I know many scooterist do wheelies,
For me I won't do them, I just don't feel the need to do them, and I'm actually afraid of doing damage to the front forks when I come down.. Also most of the streets I ride on are public roads, not really the place to be doing such things IMHO.

Yep here's the actual compression at the time..  |

Surprisingly I really haven't had any problems with the powers that be, Fawkes can be pretty loud, I'm guessing because I'm not driving recklessly, or causing any traffic problems, and have my safety gear on when they do see me.. I just don't hit high enough on their problem meter to warrant them getting out of their car, or doing paperwork... LOL but best not to push that...

We have 2 with them..one is over 5,000...the other over 6,000. What eats them up..is improper install. Folks will slap one on and end up with a compression of 240psi and have seen even higher  !! Starter cannot crank it...and I could BARELY kick it over. Needles to say on both..the cranks did not last...nor did the pistons. The detonation..heat caused by it and super high compression made the flat top pistons bowl shaped excessively. When built ours we added an extra base gasket and head gasket. This kept the pressure about 180 psi...and not a single issue in their 5,000-6,000 miles.Bottom line...a little common sense and mechanical knowledge go a long way. ;D I would have to agree with this, My first stroker was improperly installed ( no extra base gasket installed ), and it did exactly what Carasdad explained.. My compression was 205, and it did to the piston exactly as Carasdad explained.. I take the blame for this, getting in a hurry to assemble my engine instead of waiting for the right parts. I also had a 52 jug with a 50mm head, further raising compression.. At the time I could not find a 52mm big bore head.. Yep I agree with him completely |

Stock Airbox with 5 extra 3/8 holes drilled in the back half, on the bottom of the airbox cover, Keeps water out, gets enough air, had no problems.. EXactly what I was thinking! besides that,The airbox on these scooters are "tuned" not only for airflow, but for sound, I think letting a little more air into it at a time is a better method of measuring your desired performance than the aftermarket filter which lets all the air in at once.so, when upjetting, you have no middle ground.At least with the airbox, you can let in a little more air at a time, and even restrict some by blocking extra holes.If one is resourceful enough,an adjustable damper could even be made.sort of like the butterfly valve in the carb.or a damper from a grill. ;D Hi Salracer, All of that is true, also some of the reasons why I'm not fond of Uni filters are. There are two types, ones that require some sort of oil coating, ( constant maintenance and cleaning ) and the dry type, the dry type under heavy rain conditions can get wet, I had my throttle stick once because of it... Was riding to work, got to the parking lot, came off the throttle, but Fawkes would not respond and stayed throttled up.. I jerked the throttle open and closed again ( hard ) and managed to get control of him just short of hitting a curb.. It was a pretty heavy down pour, and water got into my carb thru that uni filter and prevented the carb from working properly.. This was not the throttle cable sticking, it was water in my carb causing it not to respond.. Got home that nite, ripped it off Fawkes, went back to the airbox and never had it happen again.. Some people i know swear by them, me........ I ended up swearing at them..... No thanks Ill keep my airbox...  |

Hi Tripper
Conduit is used to prevent fires for the most part, it does offer some protection to the wiring from physical damage, but at a trade off.. The trade off is condensation.. Condensation wears on the insulation covering the wires over time causing a short, also once the short has developed being in conduit makes finding the short harder...
The environment our scoot's operate in, lends itself to moisture from several sources, rain, and condensation being the main ones.. Not trying to discourage you, but wanted to make you aware of some of the possible long term problems...
Your electric company discovered this a long time ago, This is one reason why they prefer to put their wires on poles and towers and not in conduit or under ground, will they do it ? yes but in most residential cases they actually prefer not to if at all possible...
Now if you can figure a way to keep a flow of air thru the conduit to dry the wiring, that would prevent the erosion of the insulation from the moisture..

Here was my favorite Iron Horse.... May she rest in Peace..  This is a pic of the make, model, and Color Not the actual bike.. Mine was exactly like this one, 1980 Kz 550 Standard ( that was not that standard ) Most were LTD's... Rebuilt 3 times before she gave up the ghost, I flat out wore out her engine turning her odometer over 3 times and almost a 4th, driving her from Logansport to Indy and back, every other weekend for 5 years. All weather and season driving... At that point she was too expensive to rebuild and hard to find the parts, so I let her go... I do miss that bike a lot... |

I think you have not eliminated the fuel pump as the problem...

The valves are in the Head and come with the head, In my case the 50mm Big Bore head came with bigger valves. I'm told you can use the stock head with an 50mm kit, but as I understand it's not recommended, as it will raise your compression ratio to much over the long run, better to use a matched set, 50mm bbk and 50mm head, if 52mm bbk then 52mm head. The cam is optional but for better low end torque it's required.
A 150 carb is bigger, 23mm and up I think, and not really recommended for a 139qmb, however some have made them work, but with lots of effort and understanding....
I have several sources for parts, Scrappydog, Enviormoto, Mainpeace, Tvnacman, Partsforscooters, Jetsrus.. Specifically the NCY Big bore head and HP cam, I got from Enviormoto, my muffler and 50mm kit I got from Scrappydog.. The 20mm carb from Mainpeace, my main jets are from jetsrus..
I should also mention, when you change your 139 to something like this, you throw your drive train out of balance too.. You may need heaver weights in your variator, and better tires to handle the speed and power.. When you hit this level of mods, you can pretty much throw your wallet out the window.. Cheap it is not.
Good Luck
