Moped Making Rattling Noise When Idling? HELP?

[scottmorris19...]

My 50cc moped makes a rattling noise when idling but when i accelerate the noise stops, the noise seems to be coming from the kick-starter/crank side of the bike. Any IDEAS?

Pissed around with the variator?

Out of curiosity, have you informed the DVLA and your insurers that you've converted the bike from a moped to a motorcycle? And does your licence entitle you to ride a motorcycle?

I was totally not expecting that

Sorry, just that these sort of posts usually come from sixteen year old morons who think they're above the law.

Money spent on repairs should have been put to a 125 imo.

Take the side case of and let it idle, see which side it's coming from, clutch of variator, I doubt it would be clutch, wiggle the variator plate around to see if there's any give.

When was the last time you checked the rollers?

the hole becomes elongated, roller bearing battered and distorted...
the piston is wobbly sittin on the con rod end...
the old gudgeon pin would be marked ...

can we start with the most basic of information please

what the fuck is the bike?

i used to own a honda melody in 1999 (my first "bike" and only ped)

on tick over it would rattle like a son of a bitch on pick up it was fine, turned out it was weak springs on the centrifugal clutch

it maybe the rollers in the variator have worn down a bit make shure there's no flat spots on them,, but if you have gone from a 50cc to a 70cc bore then on top of jetting you will have to put new lighter rollers in as some 70cc kit make more power highter up the rpm,

why if you have a 125 cbt ar you 70ccing a 50? to run the 70cc kit you will have to get a desent spots /raceing exhurst as a standerd one may choke its performance, harder clutch spring to avoid boging at lights, you may have to pre mix the oil as the oil pump may not keep pace resulting in semi sezzing,,,
its a hole word of pain trust me

ups n downs on air filters,, ups, thay look cool,,, downs, carbs ar a pig to jet right and unless its "race tuned" thay do nout and burn a lot of fuel for 0% performance gain and thay get wet verry easy

iv had a scooter tuned up with £1500 in the engine, its all fun over taking cars at 70mph+ but evey day i had some sort of issue, i now sit hear n wish i spent the muny on somthink else

[scottmorris19...]

Choke has just arrived and we are going to fit that and see if it works and also we are going take out the rollers and see if they are worn.

Taking off the air filter and covering the port 2/3rds with your hand would have let you know if you needed a new choke, have you gone with auto or manual?

Is there any wiggle from the shaft that the variator is mounted on?

We fitted the choke and it works and runs, but i was out this morning and it cut out and it wouldn't start up again, any ideas what it could be ?
