not bad !I usually clip off the throttle spring where it wraps around the throttle arm so throttle is not spring loaded
but leave the rest of the spring in place for a spacer.
you could cut more off the front where shroud was,I square mine up even with the sides and cut the front flush with the receses in the front . kind of looks like an old cox 0.49 on steroides when i'm done.I'm pretty anal about weight though.
just square up the sides and thats probably good enough, remember were removing weight.weight is our enemy! just be carefull around where the jug and cyl. meet, in the front is very thin.
