Drain your carb, it's probably full of water.

I have tryed.Still no luck.Thanks

got compression?
got spark?

if so, take spark plug out, put some petrol in the cylinder, replace spark plug and try again. If it buzzes for a few seconds then there is a fuel problem. I am guessing this is what it is.

First,I`ve got spark and compression.When I put petrol in as you said it does a flame.I found out that the needle doesn`t go up when I accelerate.I reckon something wrong with the carb but i don`t know what exactly,I ain`t that good on carbs

the needle doesnt go up when you accelerate? eh!!

take the carb off and clean it out, sometimes draining it will solve the problem but not always.
when you say the petrol 'flamed' did you mean it fired if you tipped petrol down the plug hole? if so then it is definately a carb prob... strip it and clean it well Thumbs Up

Does it have a drain plug on the crankcase? If so pull it out and drain her off. Could have water in there or it could be full of fuel.

I took the barrel of and i found out that the piston is fucked,the barrel is touched.How much does it cost an overbore to 70 or 80 cc.

Looking at eBay, a replacement 50cc kit is about £80, 70cc is around the £100.

or just get another 50cc kit that will last, or £30 for a 60cc rebore and oversized rings.

these 70cc, 80cc kits are rubbish... and they dont do many miles... its also hard to get the mixture right unless you use pre-mix in the tank.

they dont even do much to the performance... puts the top speed up by about 4mph cos it revs to 14RPM insted of 13RPM...

wooo... Neutral

even still... alot of the 50cc full kits are around £100 anyway... Mr. Green

Few days ago when the bike was running I had 64 mph in fifth and 15000 rpm,i don`t know why it didn`t pull in sixth

also if you dont have the right mods, you will probly lose power in 6th as there not a very good gear for picking up speed...

i can push 25mph out of mine in 1st gear, but thats me kinda being a hypocrite cos i took it off the clock to find that out Mr. Green
