Hi, I found this forum whilst searching for info on the Coguar, thanks to pppdrives post's on it being a Honda engine. Obviously it would help to know exactly which model, so the search continued.
I have seen it suggested to be a CB, CG or XLR125. As I am quite familiar with CB125's both original & modern I had pretty much ruled that out, & if my memory was right the CG was an overhead valve push rod engine, but I checked anyway & the new models are still OHV push rod, leaving me to checkout the XLR125. There's not much info about on the XLR mainly photo's, but enought to confirm to me that iit is the Honda XLR125 engine fitted in the Coguar, & I would suggest that the wiring loom (should need a replacement be needed) is very similar to that of a pre electric fuel controlled CB/CG125.
