i just replaced my intake rubber on my carb and the difference is amazing had the one with the bottle on changed it for one without and the acceleration has changed so much so much pull on it any 1 who ain't changed it do it now can't believe I had that bottle on for years
Lol. Didn't really notice much difference on mine lol. That AND I bought a DEP full system. Upjetted to 240 and carbon reeds and the difference is minimal.
easy to just remove it and bung up the hole with a cork ect to test realy if it makes any diff .
I did have a great derestricting guide and removeing this was listed as for it makeing much diff I can not say . but hey if it worked for you then thats great
