2001 yz 125 big bore question?

[regal21guy]

Alright fellas im new here so i hope i posted this in the proper area . I have a 2001 yz 125 that i am currently rebuilding the top end . SO the question i have is i want to do a big bore kit on it and i know that eric gorr makes one . What are the pros and cons of both of it , is it reliable ? also how much will this run me ?

eric will do 134 and 144 for 485 I think that is everything you need. Depending on how you ride, jet and what fuel you are using they run good for a long time.

We've had two EGYZ144's and the $480 is monies well spent should you want to compete with mid-level 250F riders. Get up in mx class and the guts won't get the glory.

Great investment, post installation is ring every 6-8hrs., piston at 12-16hrs., that's keeping it in race condition. No bottom end issues and its a stock assy so replacement and time aren't a problem.

Should you be racing MX be aware of the new class structures. Lites are now limited to 250 2t's... so the 125 might prove hard to compete in B / A ProSport.

Good Luck, have fun....

The cases have to be grinded on the 144s but I also offer 134 and 139cc kits that don't require case mods. The cost is $450 for 134 and 139cc and $495 for 144s,

how would i go about ordering one from you eric ? and which one would you prefer 134 or 139 ? i ride everything from the woods to the track and i am looking for reliabiltity.
