05 ultra Andrews 21s and stage one Would a big bore kit be worth the investment? Just wondering for winter project. Any help appreciated

 

Watching in anticipation. This will be my next endeavor.

 

Yes, worth every penny if done correctly.
Scott at Hillside Performance should be your first call. They are a sponsor. He will ask what your after, won't try to sell you anything you don't want and create a kit to fit your needs. I can't say enough about what they did for me.

 

It's on my list too, and it's pretty affordable if you overbore your existing cylinders. If you want to research it some, look up 'Joe Minton build'.

 

"worth it" can tend to return opinionated responses.

The $ per hp gain on a big bore kit is very good compared to what you get out of a brand new bike.

It will be like riding a brand new bike next year at a fraction of the cost.

 

There is no replacement for displacement.

 

Joe Minton quite the fellow, he is the reason I run the 21 cams and Supertrapps.
