103" with High Compression
How many out there running at least 10.5:1 compression with a 103" big bore? Any issues? Would you have done something different? I know a lot has to do with your cams and I am sure many have different cams. But, I really want to know who is running the high compression motors and also tour with them.

I also have 10.5 to 1 compression and have compression releases, but have not had to use them. As you stated cams make the difference. I also changed to a 1.4 kw starter after two months of running the stock one. The stock one started the bike everytime, but wanted to go chrome so bumped it to the 1.4 at the same time. Put 20,000 miles on it last year from 114 to 26 degrees with an average of 41 mpg with no issues.

i just had my big bore kit with 10.5.1 compression my pipes are a lot louder. do have compression releases which iam glad i did. once the bike gets warm it turns over hard cuz a few times i forgot to push down compression releases. other than that iam satisfied with the performance just a little suprised at the dyno numbers.it doesnt add up the numbers to the performance the bike pulls pretty hard but the numbers are a little low.hp=91.10 tq=101.70 any way good luck ride safe.
