Should I buy....
 

Hammerhead Twister 150 in pristine condition...except for one teeny little thing... it appears the cylinder and or rings are bad...and it smokes big time :biglaugh:

model year is 2005 ---appears they didn't ride it much... they are asking $775

GY6 appears to need about $150 worth of parts... bolt-on; worth the effort? or should I look further? It is for my 12 year old son.

Been looking at Yerf Dogs, Kinroads...averaging about $1000 for a used 150cc. The Hammerhead appears to be a better/tough unit....seems to me that an engine is an easy rebuild...and I could upgrade/modify.

thoughts?
