popping noises

[xtasy]

hi guys,

my bike is making popping noises it started happening when i used a different type of petrol.does anybody know if this is normal? and also the kick start is always jamming and sometimes as i kick down it pops up really hard wen its half way down,wtf is going on?

more info mate...

well the popping noise is either coming out of the engine or the exhaust and the kick start sometimes just lock in one spot and wont move as hard as you kick it it just wont move.

What type of petrol is it?

 

[daniel40]

u changed your oil lately or checked it?

 

[Sidney]

It is probably because it has not got enough octane in it

What type of petrol is it?

normal unleaded (95) i was using a 92 before

i think the guy who sold it to me said after the first two tanks of petrol then put oil in the engine,im on the second tank now almost finished it.maybe time to put oil in?

 

[Sidney]

omg man have you even checked the oil since you got it?

 

[daniel40]

my mxb did this and the piston was getting stuck or something like that.

theres hardly anything in there oil , what type of oil should i use and how much should be put in?

 

[daniel40]

do u mean there is not much oil in there?

 

[xtasy]

yup lol sorry had too many beers all good tho

Do you know how to maintain a bike? Once its probably under half way it's potentially dangerous.

 

[xtasy]

should i use synthetic or non-synthetic oils? and how much should i put in the first time?

 

[stumbows]

use non-synthetic for a thumpster and as for the popping sound it could be the higher octane fuel because if a motor is tuned to use lower octane fuels which a chinese pit bike probably is then the higher octane can cause in consistencies and a rougher running of the engine.

sounds like alot of compression! must be a ducar engine... as for oil the manual would say the amount of oil it will take, as stated above use non-synthetic as synthetic will allow the clutch to slip... best brand oil out there is motul 5100 this is a 10w40 grade oil, you dont have to run it you can go buy any non-synthetic oil so long it is 10w40...

id try run a even higher octain (98%) otherwise just use the fuel you were running before... poping could also be the aditives in the fuel i.e methenol

well i was out riding a few mins ago and noticed that it makes the poping noise as soon as i ease back on the throttle, so i would b giving it gas and it wouldnt make the pop but as soon as i let go of the gas it would make a pop sometimes it would be a loud one or sometimes just a soft one.

i also have an oil leak in the clutch compartment,its leaking through the metal plate thingo ill post up a pic soon of what i mean...

 

[xtasy]

heres the pic :

the oil leaks out of that part,i took of the screws to see whats going on as i unscrewing a good splat of oil came out my question is . is there suppose to be oil in there? and how can we stop the problem?

Popping is normal.... But to be safe check your bolts what hold the header on as they are most likely loose and creating an air leak.
