Performance, way increased! It was 35 degrees outside last night when we went for a 30 minute ride and in the flat straights my buddy Brian was just inching away from me, but he has a 4.5 hp arrow motor and is about 70 pounds heavier.
Basically my motor went from topping out at around 22 mph (remember Im at 5200 ft elevation) and last night I was gaining mph going uphill and as I went by a lamppost I could see I was at 22 mph and climbing. Now I really need an exhaust!!!!
Thanks, again Map!!!!!
You're welcome Dan, Glad you're enjoying the added performance and of course the Puch head looks pretty cool in my opinion also, a good free flowing exhaust will add even more gain, just be sure to check the spark plug after you add a free flowing exhaust, dont want to have a lean run condition, if you're already a bit rich it may turn out to be a good tune for you but sure want to be for sure and not lean that engine to much.
