You have to have your case bored at a machine shop for this kit to work

When I build an engine I only use Glixal parts. They are a high quality and fit correctly.

If you have a stock 150cc scooter, THIS KIT WILL NOT WORK RIGHT OUT OF THE BOX! You must have your engined Machined before this kit will fit on your 150cc. This is a waste of money because of your going to pay a machinist to bore out your engine you can have him go much larger than 171cc for the pretty much the same cost if not the same cost. You can go from 150cc to 300cc if you want to have the engine bored out by a professional machinist. This is the long/more expensive/labor intensive route so I say again this is a huge waste of money. If you have a stock 150cc scooter or ATV THIS KIT WILL NOT WORK RIGHT OUT OF THE BOX. If you're like me and want your 150cc to go faster, make sure it is a "drop in kit". I just made this mistake and I'm trying to save others from making it. Buy a caliper (a device to precisely measure the size of things) and measure the hole in your engine after you take out the stock cylinder. Should be like 60mm. Then buy a drop in kit that fits 60mm bikes. This kit is 61mm I think which sounds close enough but trust me it's not going to fit. I tried (stupidly) to Dremel it and sand it but it's going to end badly. The cylinder fits sungly into the engine and must be precise.

This with an A9 Cam gave me about 5-6 miles per hour more on top end and a lot more low end.I turn down the outside of the sleeve so I did not have to bore my cases. So far it works great.
