The installation was pretty easy on this kit i didn't have to port match or take apart the engine at all. I have only drove this for about 40 miles now but so far i really like the boost for take off and mid range is decent. Clean up the sharp ports and make them buttery smooth for your rings though. i did manage to soft seize going top speed but i managed to fix that issue now. i went really fast on this and i didnt think i would based on other reviews. I hit 44mph on my Grande for a second or two and backed it off cuz im still breaking it in.

Looking at the other reviews, sans one, it seems that most people dont understand this kit, in that its not really a "performance minded design" this is a 30mph cylinder blasted out to 64cc's, will it scream like a Polini? no, will it give you mad torque like a Malossi? also no, will it run WOT for miles at a mehhh rate of speed like a stock cylinder with a bit more of everything? Yes, yes it will, I have this cylinder on my wifes Grande, she's taken it to rallies, and we've ridden it dubs many times, it does 41 no matter what, thats with a 12/12sha, techno circuit, Polini vario, my fat ass, and her pretty self, so ya, are you trying to go fast? dont buy this kit, are you trying to have a bike with the reliability of stock and a little more power? Buy this kit, its rock solid

purchased this kit, worked well for a while but then i had issue with it, gave to my friend and he is hitting 40mph on his ciao. I have a DR on my grande and that bad boy is a beast. I would recommend the extra money for the DR.

Original cylinder was seized, put this on my stock Grande, just had to do some carburetor tuning. Has a great low end as previously stated, high end is about the same.
A nice little upgrade
