normal, these newer 4 strokes like air movement across the radiators...I don't let our bikes idle much at all....not good for em.

Everyone always said I needed to warm mine up. I start it from dead cold, ride to the gate, shut it off and sit for 15 minutes and it still likes the hot start. That warm up stuff is BS.

It wasn't. I left out the 'bike was WAY too rich' part. Haha. I had it out today for practice. Went back to the stock 172 (from the JD 195) and 3rd clip position on the JD needle. I kept trying to use the hot start out of habit, I've never had to kick my bike so many times. After the third session I clued in though.
