getting ready to pull the trigger on a bigbore for my 07. would rather do the 107, but i'm concerned about the cylinder heat, and strength. any issues with the 107's with the aforementioned concerns? i saw some 88 cylinders and another set bored to 95 and there is a lot taken out. the shop owner i was at wasn't too keen on doing a 107 build with the stock cylinders. he suggested a 103. another guy where i live had a 95 done by him that runs hard (98hp/106 torque)for a budget build with a modest lift cam (andrews 44h), head porting, stock valve springs and compression releases. all bikes are dynoed before and after builds, so i'm not looking to go elsewhere, not to mention i've known the builder for some time and have watched his bikes run on the street and dragstrip, just would apperciate some input on reliability/rideability and a good setup as far as compression and camchoices for a 07 strretbob. not looking for a dyno queen, but something that will get off the line and have decent pull on a streetbob. would like to use stock valva train, although i'm not totally opposed to different springs and pushrods.
