If just had a dyno done and mine peaked at around 7500rpm, I'm not sure what Uve done to the engine but in my previous experience the Tri z engine hasn't been that reliable at high revs but I suppose u'll bd moving the tank and gearing a lot different??? I know the 03 cr250 engine can rev standard at 9500 and can be tuned easily to rev from 7500 up to 15000 which is rediculas lol that's what my local super cart shop runs. Hope you don't get the issues I had.
