the squish in the Thunderstorm head was 15 deg, the squish on the piston was 10 deg. Soooo after re-cutting the the squish to ten deg I ended up taking .045 off the head. Everything clears,so now I need to cc the head.

I have found that opening up intake ports such as this may be detrimental to over all intake velocity. Got to be careful how much parent material is being removed. I would highly recommend getting the head on a flowbench, even if it is a small superflow 110 model. Also on the intake port it appears to have moved from centerline and will require some manifold work to match.

My wife runs one of these bikes and has a few national records. Good luck setting it up.

The pics are destorted for some reason. Very little material was removed more of a clean up rough up, the most was removed shaping around the valve guides the throat was pretty much left alone. The intake port lines up with the manifold, I'm pretty sure it's the pic that makes it look bad, they look oval in the pics and they are not. I'm not looking for big results from the Blast, I want my daughter to have some fun and some great memories with me.

I don't want to tell you what to do and I have not that much experience at Bonneville, but from what I saw with other guys racing along with me at Bonneville:

All those that built a bike "just for fun" usually ended up breaking it badly on their rookie run...

Lack of focus at build time (it's only for fun...) cost them a week of racing and maybe a record cause some of these bikes did look great.

Get focussed on both bikes like they're the last thing you'll ever do, it'll repay both of you a thousand times in the long run.

Ok maybe I need to clarify my statement. First you are right and it is a serious project, I have been spending more time on that bike and it has put mine behind schedule. The just for fun part is; while my daughter is quite competitive, I don't want her to think that she needs to try to chase anything her first time out. If it was a real just for fun bike I would have put her on a stock Blast. BTW it is now APS/PG 500. My daughter swam and ran track in school went to the Junior Olympics, she gave it up because of the coaches and her mother, it wasn't fun anymore. So we'll go to Bonneville, have some fun, no pressure  let her make some runs. She is a lot like me so I'm willing to bet after a few runs it will be game on, if not the bike will go to my girlfriends grandson or be saved for when I have grandkids
