If you do the CRs at the time of the build it's under 200 bucks. If you do them later it's much more cuz you have to take the heads back off.

That being said, I had them installed when I had my Stage II w/255 cams done last winter. I have put 7000 miles on the bike since then including some very hot weather and a 2100 mile round trip to Sturgis. I have never used the CRs. My bike starts right away with no grinding. My previous bike was a 2002 Heritage with a 103" build with 260 cams and SE ported heads. That beauty put out 105HP and 107TQ, but when I did a hot start, the CRs had to be pushed. No problem with the cold start though. Kinda miss that bike, it was fun to run through the gears. My SG is fun too, but not quite as much.

 

I have an 103 kit. Installed compression releases...makes a big difference. didn't have them on last bike and went through a couple of starters....dealer only charged me 30 dollars since bike was already apart
