I'm finding my new (to me) GTS150 to be a bit lacking in the propulsion department. I've gone through the general tuneup and valve adjustments. It runs smoother now, just not with any more force.

I'm looking at both the DX 184CC BRUTE MUSCLE ENGINE (with UNI Air Filter) and the 175 CC GY6 ENGINE sold by BuggyDepot.

There is a difference in cost but I don't mind stepping up if the end result is worth it. I won't sacrifice quality and reliability for price.

Does anyone here have any experience installing either of these two engines in a HH 150? If so, do you have any suggestions or recommendations for me?

I'm also okay with buying a big bore kit and stroker kit and building the engine myself if I can find the right one (Compatible, complete,good quality and reliability.

Thanks.
