Looking at the bottom of my frame it appears that the engine bolts onto the frame with the 4 small round holes rather than the slotted holes based on the round marks left on the frame. Just making sure since I am going to paint my frame tomorrow and clearcoat it this weekend. I plan on assembling the bike next weekend. 20190831_171535_resized.jpg

The round/fixed holes for TC driven. the slotted were for clutch/chain driver bikes.

Thanks for the replies. I figured it was the round holes too since they had impressions left by the bolts but just making sure. Sanding and prepping a frame is a very dirty job. I got to finish it by this weekend. My wife said no more minibike builds after this one.
