Esp 30.5 rebuild

[LPREMO9]

I got the gizmos rcmk 30.5 fm in my losi and my tt has the prolite .29.5 zen this 30.5 esp is on my dune runner and I can't afford better right now

Was wondering how you like the gizmo full mod ?

I am looking to get one the Zenoah modded

My real question is how long will they last since it ported

also they shave the piston head to make it a 30.5 is that still considered along block ??

obr and esp bore out the cylinder head .

Ya but I still suck at tuning I just run em rich

Like Deluge said that could be the problem! worst case senareo if tuning doesn't help you could have extreme carbon buildup on top of piston
