NRG is fucked.

Needed a new belt as mine just went so i brought it. Went to fit it and noticed my vairator fan had went, ordered one. Fitted it all today and it sounds fucking dire 6k revs it's fine at like 15mph and then wen i full throttle it goes to 9k revs. utterly fucked.

decided to take it all apart and do it again as i might have done somthing bad when putting the vairator. 8pm earlier. it's 10:50 now and i still ahvent got it all together.

Noticed my little rubber things on the vairator backplate fell off and i stored them away in a safe place. (these wernt on in my 6k rev previous put together)

noticed when my belt went it made my front pulley go loose and it rounded off my crank splines, over the moon :huh:

cant get the little cylinderical metal thing to get to the backplate off. (as my crank splines are fucked)

so yeah, just before i ebay my bike it fucks up and i have to buy a new crank/engine? ffs

any ideas?

 

happened to me once, front pulley came off, grinded on crank. Lots of time on rubbing with a file. Took agesss

 

the rubber things there not variator sliders are they things with a v shape.

why let the belt snap before changing it. it wears out the other parts and as you know its made problems with the bike. how bad has it damaged the threads as said above they can normally be saved

 

After spending 4 hours trying to get it going i'm comtentplating just selling it as scrap tbh. Dad says i shouldnt jump to conlucsions but long story short i just got it going, fiddling with vairator lined it up right then went down road, no elec start kickstart was mangled abit but managed to idle then rev fine. it rid normally with no belt slip woo had a massive smile. down 3 hills and it fucks up again push it back and i just wanna get rid of it tbh everythings ok but variator nut was loose. when i like turn the front pulley it goes like warped abit not just a nice straight circle constant turn.

seriously pissed off now the starter bendix hasent worked since and my transmission case is practiatly falling to bits.

a new crank / engine would cost stupid money to just sell so spares or repairs/scap is all thats going through my mind (cant torch it as my insurance is 250 excess) lolol oh well it's one of them

 

If the variator nuts loose, have you lost the thread on the crank for it? If so, use a die nut to create another thread.

Obviously the thread wont be as strong as the original so plenty of loctite probably haha!

 

its minor happened to my aerox befor ei changed crank i had tiny splines i hadc to order a new front outer pully and belt, it was bodge and i was constantly paranoid, but yeh get a new front pulley too cuz as u said its sorta "warped" its the whole has gone into an oval shape from being spun around on the crankshaft when it was loose, just bodge it and get rid tbh (obviously not to anybody u know etc just slap it on ebay)

 

tune it aftermarket crankshaft and variator new belt and you'll have the perfect base for a serious tune, or sell it to me so i can pop my runner engine in there and be rid of the boat haha

It is l/c right?

Just got it done. elec start isnt working cuz of voltage is on 10 i think.


Sounded good kicked over first time. was over confident had to push it home again. done it alll again minor made sure it was all slack ect and my kickstarts fucked when i decided to cut it out then kick it again to make sure its all good, taking it into a shop saturday.

good tranny off everythings sound as u can hear in the vid theirs a weird noise like somthing flying around the crankcase.

 

300 for crank and fitting is a joke get kyle or some1 to fit it or just do it urself

 

Would cost me £110 for crank seals ect and then could get it fitted cheap. If my crank was fucked surley it wouldnt run fine for ages then just kickstart fuck up and it stop.

 

this shop is alright to be honest put new tyres on for me incl the price ect.

the starter cog (the one on the crank anyway) is fine mint it's the inside of the tranny case

the spring bit that wraps in the inside of the tranny case were it turns it over. was jammed and i took it of was mint and put it all back on inside the kickstart assembly, greased some bits their up

found some weird metalic thing wire mashed up took it out and then put it all back together, as you can see in the vid i did it all good was amazing kickstart but after like 70 kicks it went wrong.

i'm paying the shop to LOOK at my bike. if they say £300 for a new crank then i'll say ill come back later.

fact is i dont have a clue what that noise is and i don't have the knowlege to dwell deeper than transmission. if i pay what £40? for them to have a good look. i can pay them after they look at it aswell and if they don't tell me whats wrong or cranks fucked

my dad WONT be happy as it ran fine to 8 and a half revs and a good 45mph before i cut it out half way down the road stupidly.

but yeah this is a forum i'm asking you guys for help to what it might be by providing a video ect. i'm going to see if i cant do the kickstart again just so i can ride it 3 miles to the shop.

the shop is looking at it telling me whats wrong, and with the help from ss i can go further and dwell deeper in the beutiful world of piaggio 2 strokes

 

minor u were right :whistle:

both the kickstart bits are done now really anyway me and dad decided to still put it back together to make sure and i managed to get it going (easin on it slowly and then pressing hard and boom starts (after 50 goes) so ye)

went up road sounded sick pulled like a monster (didnt think no belt slip made a differnce)

2 coppers giving me evils and pull me over -.-' no tax disk ect ect they let me on my way cuz they know were i live and everything was legit and i explained i put all that on the tranny case.

ofc i had the engine off so i had to spend another 50 odd goes getting it going again (some lads didnt think i could, should ahve just pushed it home lolol)

got it going went home and then it died on my drive way 8k revs down to 7 then die (all at full trhottle)

dont kno thought taking out my eletric start would stop it jamming or whatever if i didnt put it in properly but it still dies.

 

lol police let you off because you explained to them about your tranny case bet they dont even know what your on about

 

Ran it to my local tecos today airbox fell of 2 times (Need a dye redo the thread, nut and bolt will do atm)

Eletric start has started to try and engage now. Any tips on putting it in as all the times ive done it it hasent worked.

New cog is on order should be here thursday.

I managed to cable tie my airbox on. And on the way home it is running very bad. Not sure if airbox was loose causing it to run bad but it was like 7.5 revs and wouldnt go to like 8.2 it normally does. Slugging off the line although at barely any revs seems to move better cause of no belt slip but yeah, somthings wrong stopping it from going to 8k revs and it's ruining my performance cratch:

When it's working :hmm: the clutch comes in at 6k revs and goes. If i put stiffer springs in and it kicks in at like 4 or 5 would it better of the line?

 

chilll i got confused. took it into shop anyway to sort my elec start out kickstart bit should be here soon and there doing that as i cant work on it in a 9 till 5 and boxing straight after and want it for workkkk
