125 or 144

[Jason145]

Since i value the opinions here on pit racer I want to throw this out there and see what feedback i get. I'm building an 03 YZ 125 and need a crank and cylinder, that being said whats the advantages/disadvantages of the 144 over stock if any? Thanks in advance for any opinions

144 has more torque and all the rev, if built correctly. No other way to go !

Correct me if I'm wrong but i don't believe those years will interchange, 99-01,,02-04,, and 05 up? I know the head, plastic, and exhaust are different! Thanks for the info tho Tom, much appreciated

If you are rebuilding anyway, stroke it and bore it and make it a 153cc.

Pulled trigger on 08 KTM 144 SX last night. Thing is sweet!!!

What is someone looking at to have a 144 kit put in their bike? I got an yz125 (2006) and the thought has crossed my mind unfortunately I'm not too mechanically inclined...

Any suggestions on where these parts could be obtained and recommendations who could do this?

How do i get ahold of this Mr. Gorr

Strong +1 on Eric Gorr. Much better quality / end product than the Athena kit. I don't have his contact info, but I am sure you could search either his name or Forward Motion (his company).

If you already need a crank and a top end / clinder, going to a 144 comes out to less than $200 additional $. Best single performance mod out there, IMO.
