Mongoose / Mongoose 90 big bore kits
« on: October 18, 2011, 06:29:24 PM »
Hi, I am new to the forum , but not to ATV , dirt bikes , strret bikes etc 
My son rides an 06 Artic Cat DVX 90 , which is a Kymco mongoose with different stickers. He has really gotten into competing in dirt drags at our local fair grounds and now im looking for some more HP for him
I have found Powroll offers a 120cc kit, but , after multiple emails and phone calls ( with no respnse) I have began to wonder if they are still in business or if I even want to do business with them.
So my question is has anyone succesfully used a big bore kit, or even just a cylinder and piston from say a 125 or 150 scooter on a Mongoose 90 ? I have heard of people using the cyl head from the People 150 in conjuction with the Powroll 120 kit as a higher flow option so I have to imagine at least the cylinder stud spacing is the same.
My end goal is to get around 150cc's and hopefully be able to run pump gas as opposed to race fuel.
Any input is greatly appreciated
