<HTML>i just purchased a 70 cc big bore kit for my tomos and i'm real happy to say that the piston and lower half of the engine block is shredded. at first we thought the ring came off the piston and grinded the wall due to not enough oil being cycled through yet but upon inspection the ring was intact and in place. so we're assuming there must have been an unseen abrasion in the cylinder that caused the destruction. so pretty much i am officially screwed. i still have to see about how much a replacement will be. so just as a warning to all be sure to check EVERYTHING if you opt for one of these kits as there is no warranty whatsoever on these things. and actually we had to drill out new holes in that block before it could be installed as all the original ones were crooked. that shoulda hinted me off that it was faulty but impatience rocks man.
yay spending an extra 300 bucks for it and then it breaks
