Wiseco pistons
Gado, I just had these pistons installed in August. My mechanic says he has done a lot of conversions using these and has had no complaints yet. I've only put about 3000km (1800 miles) on the bike since then. Only thing I found is the engine runs hot, but I expected that. It is a long proccess to get everything worn in. I still haven't "paid the Harley tax" although I just put a down payment on it with the purchase of s&s slip on mufflers (not installed yet). I can notice quite an increase in power and what I really noticed was the holding power on a steep down hill. It also sounds different and I can't wait to hear these new mufflers. After the mufflers comes the rest...less restrictive air cleaner and new jets in the carb. Then it will have a few more horses. By the way my bike actually did less spitting and popping after the conversion than before and the carb was not touched. Anyway good luck.
