Harley has them but you must modify your 103 heads or buy the 103 plus heads from Harley. That will yeild about 10.5 to 1. The pistons can be relieved to lower compression
ratios. But you must modify your exsisting heads for these pistons. I am at work till tomorrow and don't have the part numbers in front of me.

Thanks Otis I don't think I could have said it any better. I wasn't going to buy heads and modify the stock ones. After I saw them it was an easy choice.

Dawg,
With the compression increase does the bike have any problems with preignition or detonation ?
