Case boring is where they bore the opening to the bottom bottom in so the cylinder will fit in there and the crank will clear

You will have to split the cases and remove all the internals. It's going to cost you

Yes, appears a crate motor would be more feasible.

Much easier sneaking less than $100 dollar items past momma!

Gabriel, would 140cc eliminate it from certain classes of TMGP?

1. Create Imgur account
2. Add photo
3. Click and hold photo and copy link
4. Use IMG tag on MH post
5. Paste link between IMG
6. Add a l as in Lima to designate photo size between the .jpg. l.jpg

Good luck!

Porting n Polish

Reducing exhaust restriction.

A brief neighborhood run confirms quicker throttle response. Kids think the bikes pulls harder also.

Test N tune this Monday at the Katy track will confirm how much performance we gained.
