Last month I started rebuilding my wifes 150cc buggy. It was 4 years old and has been raced, rode and just had the tar ran out of it. The buggy started out as a carbon colored Hammerhead 150gt.

Now its orange and I am now building a stroker motor for it. The engine will have a 3mm stroker crank, 61mm cylinder instead of the 58mm, A-9 cam for bottom end and midrange power

Thanks, the new paint and new wheels along with the bed coating for the floor really made her happy.

I have the crank and cylinder ordered, hope to have them by the end of the week

Cool pic, looks like you are doing a real good job. How much horsepower will it have when finished.

her's was faster than mine to start with, it would run 42mph at 10,230 rpm. did that so I didnt have to here about " my buggy is to slow ". got the stroker crank in, 61mm big bore on. piston to valve clearance came out great so now I am waiting on the shims for the cylinder to get here so I can get it back together

got the shims in and the engine assembled and installed. I must have done something right because it fired up and idled the 3rd turn of the switch :D

been out riding up the street where I live, feels strong and at 30mph it was turning 7520rpm. going to take it easy for a few weeks to get it broken in. useing royal purple break in oil then going to switch to the 10w40 royal purple

You are the first person I've ever seen put in writing that they use Royal Purple. It's the only oil I use in the bikes I service and my own personal. Fantastic stuff. Sorry... I get geeked out about it. And no, I don't own stock. :D

it is some good oil, with the 61mm cylinder being a slip in I want the best protection against heat I could get, I also added a oil cooler and spin on filter
