ok after my last post i headed to the lake for some more test and tune . heres what i got .
first still running the buggy pipe i backed the niddle out 5 turns and started it up " this was with out doing anything but relubeing the flex cable " filled it up im running 20% at the moment cant get anything higher . ok i set it in the water and wow what a diffrence . but still no top end but it wasnt cutting out like before . so i had also cut down some props that was a 3 and 4 blade with less pitch then the stock 2 blade . heres what i got . one a little slower speed and i was hitting the top end but i was airating the impeller . about 1/2 trottle was it after that it just rev out . so that tells me some i need to tune my pipe for a little more upper end torq . to get the rpm up . what do you all thank .
