Listen I wasn't arguing about whether or not Polaris made a 250 reed cage engine but these were listed on eBay from a dealer with a 99.9% Positive feedback score for my wheeler year make and model the item number is 270383805028 and he listing title is "POLARIS 87-93 250 Trail Boss 4x4 Boyesen Power Reeds" It's my mistake no bi deal but all the other 2 strokes I owned or still own including my,little Yamaha Blaster 200cc have reeds so I just made an assumption and thought it would gain a little power as well as just doing some maintenence on an older quad. So now that I ve learned a little about the quad Im waiting to hear back from RcR about a stage 1 kit. And I was just trying tyo find out if the DG Pipes for the 250 Trail Boss were the same as the the 250 4x4 because I have a friend a town away who can get me a brand new one for an even swap for my stock setup of theyre the same because his daughter hates how loud her 2x4 trail bos is. Thought it was worth trying to find out.
