I just got done a HPP cyl conversion and 144 Big bore kit on my 02 CR125. Wanted to verify power valve operation after swaping the governor and linkage. Pretty cool to see the power valve operate. Enjoy



Millennium did the big bore. Pretty pleased with how it came out. Had it set up for 100oct fuel mid-top porting. They spec’d a .040 squish and it was .041”. Not to shabby.

I finally got around to using that cyl I got from you 2 years ago. Lol. Unfortunately I did not get the 98-99 valves. But it almost seems some of the benefit of the newer valves is cut/machined away to accommodate the larger bore. it seemed pretty preppy riding it down my street.

Aren't Millennium and Gorr the same place/people?

Why not Tom Morgan Racing? I remember he did the Blackfoot Honda bikes up here in the early 2000's and those things were fast.

Could be I don't know. I want to find a place to have the work done that is trustworthy. I have seen a lot of bad things written about Gorr's service on the internet

Gorr has been back on his own for a while.

Tom Morgan works at....Millenium.

Eric gorr and millennium parted ways a couple years ago. All the poor reviews kept me away from going to Eric. Tom Morgan is the technical/performance director now. After a handful of emails earlier this year with Tom I felt confident sending it to millennium. I wasn’t sure what to expect and I’m pretty picky. Looking over their work everything looks great and very professional. Porting is clean and looks very targeted to certain areas. I may post the kit in the product reviews.
