Was wondering if anyone was having issues with the stock rods when building a mild engine package? Currently getting ready to do JE high comp piston, head porting, valve job, and ecu tune for VP fuel. Not wanting anything wild in terms of power level, but obviously want to maintain some level of reliability. Has anyone had issues with this type of build on the OEM connecting rod? Thanks for any input!

I have a Racetech modded head on my 19 250 on stock bottom end. Currently running Vortex ecu with maps from XPR Racing. Yosh exhaust and up 1 tooth on the rear sprocket.

Overall it’s a big gain over stock and almost at 50 hours on the bike( about 20 hours on mods).

thats what ive heard, currently running a tuned stock ecu on T4 fuel with yosh exhaust and 49 tooth rear sprocket and that alone was solid. but i figured once i tear it down i might as well get the head done up, so thats good to hear!

im going to start tearing into it this week at some point, bike currently has 30 hours on it. we've always done pistons, camchain, and inspected the head around then. so i figured once we tear the topend down i might as well add some goodies
