I would definitely think the cheap silencer pulls som power away,not the good ones though,truck looks good,wow I bought the same motor right before my zenoah and it was the cy-gp290 with the stuffed crank 2 bolt which I didn’t know when I bought it,and of course it was a little faster then my stock hy but I was not impressed at all,it just seemed like it didn’t rev as high as it should do I called ddm and he told me ya that’s not the motor you want cause I was gonna try and get a bigger top end but he said they have nothing for that motor so he told me to buy the zenoah 320 and dammit I was gonna buy that first but of course I figured d save a hundred bucks lol. Get what you pay for but if you think your xt runs good with that motor wait till you up it to the zenoah. Lol night and day!!!Man good luck with the mt think you almost have it dialed in!!
Thanks!! I tried my best haha yes that cy29 gp29 don't rev much! maybe cause the stroke? mine is 30mm stroke I heard bigger stroke lower revs
