OK thank you, I'm interested in that mod but do you think the work is worth the upgragde? I mean what other advantage you get of doing this, except the water running in the cc. Power, more rev, easy start, whatever... From what I read on this forum (after doing a reseach on the subject) it seams that not everybody thinks it's worth it.

 

For horse power, I don't see an advantage. If you like diving into deep-long puddles, you have to do the 'vent mod', and while you doing that, you may as well move the cc vent to the top of the box(smog port). I believe the engineer who put the cc port at the bottom of the box should be slapped...repeatedly.

 

Maybe I should've ask this before but what's the purpose of the smog thing and the crankcase vent on the stock form???

 

Crankcase venting to the airbox allows vapors from the cc to be removed and channeled through the induction system and burned in the combustion chamber.

The smog system allows fresh air to enter the exhaust system, at the exhaust vavles, to increase heat to the exhaust pipe which in turn allows the catalytic convertor to work at an optimum level.

This is a very basic description.
