I know its an old thread but i acctually brought this quad and my god do i with i hadnt! I picked it up but the seller said it doesnt run at the moment but we took it anyway with a bit of the price knocked off, but only to find out it was just the spark plug, but then we started it up and it was puthering with smoke! We took it to a garage, and not only were the rings snapped in doing do had scratched the bore which then had to be sent off to be re bored and re chromed? This set me back 400 quid,truthfully i think the welding was quite good!, i an currantly revuilding the bike, ive had everything stripped and powdercoated and to be honest runs like an absolute dream! I couldnt be happier, and its fast for a 250 aswell! Overall i suppose it would have been better if i hadnt of got it but in the end im so happy with it,, just puts a smile on my face when im roding on the back two wheels hehe
