You want the piston attached to the crank, squeeze the rings in, slide on the cylinder.

you didn't by any chance install one of those racing CDIs did you? You may have problem with you pick up coil or a short in the wiring. you may check your grounds and the CDI connector/plug make sure nothing is loose.

I also learned a trick about about the oil rings. if you gently and carefully squeeze they bend in one direction and one direction only, the ends should point upwards if not flip it over so they do. EDIT: yes there is you need a tool, thank fully it can be made. what you need is a ring compressor . . .    I think you can make one out of a pop can or tin can. |

not sure if this is the same thing but, the last time i replaced my belt it was acting all Fed up and would start and if it didn't wouldn't idle. The variator had locked up, probably from using an impact trying to get the nut off. long story short a few weights went sideways. it was basically stuck is gear.

If the engine was over revved the valves can float (cam and valve moving faster than the spring can react), and the keepers can pop out. If keepers pop out the valve can slip down into the combustion chamber(called dropping a valve). If the piston hits the valve it can damage the piston and valve or possibly the rod,cylinder and head. It is also possible the keepers wore through the valve spring retainer, weak or broken springs, or head damage. In any case be sure to locate the keepers. They can cause a lot of damage bouncing around in an engine. Yep, new head is probably the best solution. Roy I was told stiffer springs or even secondary smaller inner springs being added can help prevent this, the last time i took my engine apart a friend installed better springs and added spring shims. |

yeah double check all your connections. one time i was getting annoyed and couldn't figure it out, turned out one of the wires on CDI connect and had worked it's self loose, of course i also replaced my throttle cable and a few other things.

You might have a microprocessor built into this light assembly. Some microprocessors are fussy when it comes to electrical noise coming in on the power line and they may not allow the light to work. The light works fine with the engine off because you have clean DC power. Once you start the scoot, there is rectified AC and other electrical noise on the power line which may not be clean enough to allow the LED assembly to work. This replacement light is probably intended for a motorcycle or scoot with a much better (cleaner electrically) charging system. In other words, this light might not be compatible with your scoot. is possible to upgrade the rectifier setup? Roy could you link us to the unit you bought? |

I've never had a dui in my life, i'd never touch the wheel or handle bar intoxicated, thats how people get hurt, my uncle nearly killed him self when i was little due to drinking and driving . Besides people install BBKs all the time and you guys don't start telling them to buy a 150 and that they have DUIs, don't be such a debby downer, in the end aren't we all into scoots for fun as well as work/transportation.
Also they say there is no replacement for displacement, this is true but, extra compression sure does go a long way. They have a whole slew of options for any thing 47mm and above but, mostly 150cc gy6.
form what i can see there are a ton of quality options for you 150 guys. i'd like try stay and small bore mainly because 150s are notably bigger frame wise and I'm short also for mpg my thinking is it's a smaller bore so it can only suck up so much air and fuel depending RPMs.
So i'm trying to consider other mods to do, which i have tons of ideas for now it is coming down what can i buy for it that may be useful and we have already cover bbks and cvt but, not what is best mod on the cvt.
perf carbs seem be nothing more than fairy tales as well CDIs and coils. Cams exist how ever not many people really talk about those much they seem to just buy a bbk kit and take what ever cam it comes with.
Every one seems to sell air filters and jets but, i don't really think at 49cc a high flow filter is gonna jack.
Weights seem to be hot ticket item they are certainly cheap enough, i don't think quality matters with weights does it? what about these supposed hot rod variators?
otherwise it seems like i'm gonna have do some experimenting and report back.

Nice scoot man looks good with nice contrast, I like it. How do you like the trunk? I've been thinking of building a flat rack for mine since i haul boxes and computer towers from time.
How does it Handel? It seems it runs just fine with all those miles. Remember to use good oil, if i can make a recommendation I hear very, VERY, good thing about the lesser known (at least to me) schaeffer oil.
Apparently schaeffer oil is good stuff and last a tad bit longer than normal oil. Now that I think about I need to putting that stuff in my scoot.

That didn't really make much sense to me.
It seems the vote does to NCY products.
EDIT: I'm guessing that is an Insult, all i can say is that's not you, you're nice guy I have seen your other posts.
I'm not really trying to get in any arguments, so I apologize. It is just that I like a challenge and to be different. the 50c doesn't get much love and that why I love it. Besides where i'm from you have to license 150s, so i'd like to up my 50 but, not by much just a little bit.
It is partially my fault i should probably have mod merge this with my thread "faster" and i could have been more clear on what i wanted to like what an after market torq sheave does and ask why they have larger diameter face or if after market shock help to make a smoother ride.
So I apologize for offending any or not making since. i understand what I am trying to do may not be very cost affective how ever I am trying to make something different and I do honestly get a little bit of a freed ride on cost mainly the scoot it's self was free(front end was almost totaled[fixed with blow torch]) and some machine work and porting (friends), so it's not like i'm trying to burn money.
I'm just trying to learn and have fun and be a little different that all.

i already have 155cc it does 75mph,
really a 155cc that does 75mph 
all day or for like 100 yards?
are these "drag strip" bikes that u re-build after every run
or daily drivers ?It is a 1974 z50a with a PitsterPro Z155 HO w/ lighting coil. It runs like champs and will can make the header glow. It honestly doesn't give a s*. I've never found many places big enough to do top speed runs. Any who back on topic i found this a third the labor at nearly the same price. www.mbe-motorsports.com/catalog/product_info.php/cPath/19_106_2/products_id/150EDIT: has any had any experience with after market torq sheeves to they make for a higher top end ratio? and has any one used/installed after market shocks? i have the same scoot as terrilee except it has a 49cc. |

i already have 155cc it does 75mph, back in the day honda had 50-65cc engines that could 50-65mph. I have a friend who is a very skilled engine tech. I'm looking for a solid 45mph will all around good performance.
and some of this stiff is pure poppy cock like the more mods the sooner it dies, if that's the case stay out of the garage if it's too hot.
any a friend is very skilled tech i already got a killer port job on the intake for free it really helped. it seems like CVT may be the way to go. i already have some bbk stuff on hand including a 63cc HIGH C:R piston.
longevity is a concern and is being accounted for and some modification for lower temps already made.
some of this another story. So far i think sprocket had just about hit the nail on the head. i want to hear more about mods that works money aside say i'm a spoiled rich kid and money doesn't matter, not that all Chinese parts are bad.
