Two years back I bored out and stroked my 88 to 110 ci running at 10.1 comp. on the plus side it developed 110 HP and 109 Tq. On the down side it ran real hot. I tried everything to cool it down including running 98 octane. A friend put me onto Ultra cool which I bought and added to my machine. Absolutely the best thing I did. The engine runs real nice, stays cool even in stopped traffic in 80+ temps, two rider and full load of gear. I recommend this to anyone even a stock engine because we all know a heavy load and a hot day will over heat your ride. With Ultra cool that will never happen again. Thanks for a great product.
