headlight and back running shut when accelerating

[matlock]

please help i put big bore kit and removed that rubber cover by the intake rubber base i didnt put it back cannot figure out how but when i accelerate the headlight shuts then when i let off it goes on sometimes it stays on but not long if i hold the motor down with my foot so it doesnt move up when i hit the throttle the lights styay on perfect im ready to put a block of wood between engine and frame i cannot see anything shorting out i touched every wire and bothing its only when the engine moves when i give it gas then sometimes it stays off and i gotta  keep hittin the throttle till it flickers back on please help

Have you removed the lamp and checked the the filament isn’t broken and occasionally making contact?

[matlock]

yea its the brake light also if i place block ogf wood between engine and frame tightly it stays on

Headlight and taillight are AC generated from the stator then to rectifier/regulator to switches and to lights. I’d thoroughly inspect for loose connections or a ground that you didn’t get back on during assembly.

i see nothing wrong i wiggled everyt wire it just happens only when i accelrate the engine moves and the lights shut off no touching wire doesmnt effect it only when i hit gas and motor move upward i check for squishing of wires etc saw nothing its almost like in the motor there is a level type system that shut lights when motor is on certain angle i really and stuck and upset

[matlock]

well i checked everything on scoot i cannot figure it out tomorrow ill post a video thanks guys

i was going to say. send a picture of said plastic piece and also where you are making contact to get it to stay on. i hate electrical problems but have dealt with quite a few over the years. they can take some time to figure out but usually just something stupid and it makes you feel bad when you figure it out. also what kind of rpms are you turning? my stock electrical doesnt seem to like anything past 12k for charging but idc what it wants i want it and its gonna have to play nice. also my stock regulator/rectifier started blowing bulbs when i switched to a malossi overrange mansplain that i dare you because its impossible. ive tried ive failed and now it doesnt matter. headlights now run off battery and i still have the same rectifier and regulator and the battery charges fine. except when i go over 11k rpms it will start to lose some voltage but you hit a cruising rpm and im right back to 14.2ish volts.
as of right now i would agree with ryan that a ground is most likely to blame but none should have been disturbed during the bbk swap. but pushing the motor against the frame may be causing a bad ground to make a better connection or pulling on your plug for the stator and making better contact. on my bike there are 2 grounds. one at the starter thats long gone and 1 on the frame in this picture.

if you look in the center of image you see an ignition coil boot. look straight down from that youll see the metal tab the coil is mounted to. and you look down from that and there is my frame ground wire that isnt hooked up. its redundant on mine for various reasons but i hope it helps. check and make sure connection is clean and also check the fuse for the bike as those are sometimes a glass tube and are garbage. water will get into them as they age and can just stop working or separate and cause all kinds of stupid things to happen but look like they are still fine.

heres a link to see the pics of what im talking about www.facebook.com/photo.php?fbid=2613304758737217&set=pcb.2613306038737089&type=3&theater

says online the black rubber thing is a deflector

[chehystpewpur]

no offense but those pictures are pretty hard to tell what im even looking at. your scoot seems to be set up different than mine but i cant make anything out in the pictures.

what i can tell you from the pictures is you need to fix your cooling shroud your gonna ruin you cylinder having it split open like that pushing down on the motor may be pushing the shroud back into place and relieving some wires. it looks like the wire from your stator is getting pressure applied to it by that rubber flap and the cooling shroud. the metal bar over the stator is also quite close to the stator wire and motor and if the motor is moving up there is only like an inch of clearance so it may be getting pinched. also it looks like the fan inlet of that shroud took some damage maybe from a fall or tip over? from what i can see in those photos more happened than just a bbk install. also it looks like some oil is running down the top of the shroud maybe further making me wonder about a fall.

[matlock]

no totally wrong assumption i installed big bore and forgot to to put bolt on fan shroud cover and i fell when i was driving and began melting on exhaust and rubbing into cool fan when i noticed it was too late i ordered a new one should be here maybe tomorrow and the oil is from the oil injection tank i filled it all the way up it has a overfill hole for air so it will drain down when needed when i push the rubber cap on it over flows through a tiny hole on top while i make sharp turns or sudden stops hills etc yes its a hazard sorry for those who wanted to say that but it was never ever not once fallin or tipped over is that something you do often chehystpewpur?

[ryan_ott]

You’ve got a loose connection somewhere. That rubber mat is not needed I never reinstall them. Your forcing a connection with your foot or board, track it down.

[chehystpewpur]

i highly doubt my bike would run as well as it does if i tipped it over all the time... at any rate if your forgetting to put bolts in it sounds like this problem should be pretty easy to track down.... im only commenting on what i can see and i see damage and fluids that shouldnt be there. there is no need for personal attacks. also its not an assumption more like an observation or intuition. i have over 30k miles on my bike and zero spills and only 1 tip that ik of and that wasnt my fault it was stored at a "safe" location and something knocked it over and wasnt stood back up until i found it like that. needless to say its with me again. bikes go down damage happens and id like to help you sort your issue out but you seem to have an issue with your mouth and other members and if youd like to be rude someone else can help you out it seems as other members have taken this stance as well.

from other posts youve done there were wire problems and that could have caused more problems down the road. that being said if you dont have a ground issue which you havent reported your grounds are good and clean you most likely have a hot wire issue and should isolate the circuits and test them properly and report your findings so you and others can learn from your experience. have you pulled your flywheel off lately to make sure that your stator didnt suffer damage and needs replacing? a visual inspection is easy and can save quite a few headaches while checking everything after it. running a new circuit to the headlights and tail lights could also help you find where the issue is even if its just temporary. most wires should have a pretty low resistance from point to point and if its high or shows open its usually the culprit.

this is not elementary school peewee so lets not get into to the "wha im a baby other people had problems with you too wha wwha "peepee thought to himself" i need to bring up other incidents because i feel like an asshole i made an assumption" wha wha the word assumption has the word ass in it because usually its a asshole who assumes" not trying to attack you punypeepee but c/mon man any ways thank you guys i found the problem it was a punched wire in the tippity titty top of frame a black wire and white one were pinched from when i seperated engine from frame to take off the intake tube and swap out steel reeds for the new malossi ones my mistake thank you everyone.

This will be the last warning matlock. You've already had more than most, but you do seem to want to be here. If you only knew the odd things we've seen people do to scooters and especially the amount of people that we've seen think air shrouds are pointless and leave them off or not worry about them. Who knows how many people maybe didn't ruin an engine because someone happened to notice that or something else in a pic. If some of us see things wrong, regardless of if they're definitely related to an issue, they may be brought up. Sometimes people do make mistakes and don't want to admit them so we will ask. It's not intended to offend. If people want help, sometimes we have to dig a little to see what's going on and take our best guesses. I have people point things out in my pics, vids and info too. It's not like anyone called you names. People are just trying to help and no one really wants to help when they get an attitude for trying.
