Hello everyone trying to find a set of high compression pistons to suit my 07 dyna they will need to be 103 cubic inch and arround 10.2 to 10.5 to 1 these pistons will need to work with the stock cyclinder heads as I am having them ported. Brands,suppliers and contact details would also help as I'm in Australia the land down under.

 

I got mine from the dealership.

 

you can use the earlier 103 stroker pistons in your 07. you just have to either buy the bigger bore cylinders or bore yours out. I don`t have any part numbers avaialble andI can`t remembe how many different sets were available but you should be able to find what your looking for. I think the flat top 103 pistons are goof for 9.5:1 with stock heads. you could always shave your heads a bit to raise the compression and run a thinner head gasket.

 

I have those in 107" for that stroke. Just bore your existing cylinders.PM me.
