LOL ! your not talking down to some clueless fanboy here my friend ! I am very familiar with the Dynamite engines....Cast piston,soft Taiwanese metals, loose carb o-rings...thanks, but no thanks ! I mean other then the newest Dynamite engine their engines have been made by SH....you cannot compare the material quality of a SH engine to that of a Werk's...The Werk's pistons are harder, the cranks are harder, the o-rings in the carb fit snug..the overall fit and finish is better.... Now the new Alpha built Dynamite is a step in the right direction, but its still a cast piston..when I mod these engines the real truth on material quality comes out...I can make a Werk's scream to the moon and it has no issues handling the extra power and RPM...the Taiwanese engines don't handle the extra power and RPM nearly as well as the materials are not as good....I have done many extreme mods tot he Taiwanese brands and the outcome has not been good, yes they can make awesome power, but they don't hold up nearly as well as the Italian engines do....I even have a mod Go GX 7 port I did sitting here with a snapped crank...engine ran like a bat out of hell for 2 gallons till the crank snapped....I got another GX 7 port that the piston collapsed under the wristpin.....Plain and simple the Taiwanese do not use the same quality of materials as the Italians do..We can push an Italian built engine much harder without failure, that is a fact that I have experienced many times over the last few years...I wont argue that the Taiwanese don't perform well, as the new Alpha's do scream....But to say they are more durable and better built then the Italian engines is just pure bullshit !
