So I suppose since your saying it's bored out ,we won't be getting bore kits to juice up the engine ???
That sucks ,I was so looking forward after few months to get a bore kit and enhance the engine ,or I may be wrong anyone has an info on bore kits on 750 ??

This company apparently plans to sell performance cylinder head packages for the Street: Media - Short Block Charlies
Not trying to advertise or recommend this particular company. Just giving an example that there will be aftermarket kits available to modify the heads for better performance.

My understanding is that there will be big bore kits available to allow a builder to build an engine larger than 750 cc displacement. What Sherri shows us with Short Block Charlies (whom I had not previously heard of btw) is very interesting indeed since it includes head work.
