how many hours before rebuild

hi to everyone
just found out about these pocket bikes and just doing some research,
i have previously raced karts and am looking to maybe buy a bike.
just wanted to know what sort of running time before rebuilds,pistons ,rings etc and what's the life span of the motors.
any info will help thanks al......

my air cooled engine was modded a tad on day 1...

personally I don't think you need a bigger piston etc..

If you get a 50cc bike..then you already have more power than most bikes on the track..and then you can just change other things..

I've gota lightened flywheel...second piston ring out..bottom gasket out..and my bike is KICKING *** against the rest of the field..

how many hours roughly has your engine done as i'm trying to work out the reliability of these bikes.
i have been told not to waste my time with chinese imports...
i have seen the italian bikes and they are more of a racing machine but at a larger price.
do any chinese imports compete with the polini's etc

a guy in the other forum told me he bought one of the chinese bikes followed by 3 of hes mates buying the same model from ebay he reckons they are good for there price i am following there foot steps... with these bikes they are cheap and parts can be bought with pocket change hence the work pocket anyways with any 2 stroke motor the rings should be changed every 3 months and piston 6 months at the 6 months use i would consider a full rebuild including bearings either way u can tell when a conrod bearing is worn out simply look at the grey or brown colour if this colour is gone time to get rid of those bearings! i have also red by changing the motor bearings in these chinese models makes a noticeable difference in power i wouldnt doubt this either :wink:

gazza- so after all the info ozscoot has given you..you ar estill going to buy a 40cc bike of ebay?? mate..for an extra $200? you can have a 50cc and alot better bike..

al...my bike has done roughly 40 hours of racing and practice...and is still going strong..

But, it also depends on how your using the bike? Mine is strictly track ridden...It's never been on the road.. I probably wouldn't do any engine mods if I wasn't racing..

i dont have the extra few hundred as i said in my other post i just spent a few grand on a bike 2 weeks ago and girlfriend not wanting me to buy one of these bikes doesnt help but im still getting one :P

Then wait a week or 2 until you can...

Do you have a job?? Ifso..what's the 'average' income of an adult? $600^?

I'm 16 and I can afford a water cooled and an air cooled..and heck I work at Woolworths! and get paid like $300 a week :oops:

Surely you can afford 499 or whatever it is?

im on sick leave at the moment gotta see a specialist the wait is over 4 months :shock: and bills dont help

Good thing about being 16..no bills :twisted:

But yeh mate, it's your choice..I don't mind what bike you choose..

lol i remember when i was 16 i still had bills but just not as many im now 24 and nothing has changed, if i get the cash i will buy one from OZscoot but if not it leaves me with no choice if i dont buy one soon i wont buy one i will loose interest i just want to see what all the fuss is about if i like it i might think about racing later on down the track as im at a good age and weight 73kg to flog the oldies haha :twisted:
