Re: wrh 68cc cylinder kit
We're running one of WRH's aluminum 70cc (69.7cc) kits on our Polaris 50. Along with that, we have one of the WRH pipes, a 20mm carb and a few other of Billy's items.
It made a big change to our power and speed. We can now run a sprocket combo that before (50cc, Tecnigas pipe, stock carb, some other minor changes) it wouldn't pull the big hills... now she gets air off the tops.
Billy knows his stuff and will do you right. Give him a call and let him know that Alyssa's dad reccomended him.
