You can remove the WHOLE brake system on front without opening a line. But...you'll have to be careful to not get air in the system...so I'd overfill the resevoir when taking it off to be safe.
It's not the drag, it's the weight savings.
VForce would be a waste to me without a ported motor, others my disagree...
Neither pipe, CPI or Shearer is going to run as well as it should without porting...but, of the two for your needs, CPI will be better. They come on sooner...and have a broader power span than Shearer....
Tires are key!!!
Smoothies up front will always help, way less drag.
You can remove the pipe tabs, air box tabs, heel guard tabs....minimal weight savings, but...cleans it up a bit.
Those rules are pretty tight...gonna be hard after that.
I kinda browsed this thread....you have higher compression...did you bump the timing too? What about a shaved flywheel? (Sorry if you already covered that...)
