Why does this keep happening

[kev0175]

Ok guys need a bit of advice. For some reason I am breaking head screws, I looked up some theads but couldn't find any. My MT has a 29cc big bore head kit with a DDM Dominator pipe. I have broken 2 screws in the last 2 or 3 weeks. WHY????

Are you talking about the bolts that hold the head onto the crank case or the bolts that hold the pipe onto the head.

Its because there is too much chassis flex, you need to install some good chassis braces or a quality roll cage.....

Or make it a two piece pipe.

Sorry about that it's the bolts that hold the head on. I was thinking it was the pipe too , wasn't sure

Yep. Chassis flex and a one piece pipe can do that. You could make it a two piece pipe to add some flexibility. Cut it and make yourself a coupler. Something like this.
