Tell me what you guys think here.
I have a new Malossi 62cc. I've got two carbs. One is a 16mm SHA and the other is a 19mm PHBG.
I've got a custom intake for the 16mm SHA (Made by Bandit Ryan). It's a stock puch exhaust header cut down with a piece welded to the end that has a 19mm ID to fit the SHA carb. If I use this carb I plan on opening up the intake on the Malossi, (Just on the outside without doing any opening up on the bore end), to match the ID of the intake which is about 21mm. Basically I would do this just for flow purposes and have it ramp down to the 16mm at the bore. I wanted a facing forward intake to make tuning easier and that will allow me to rock a high flow filter.
I've also got a 19mm PHBG with a 21mm intake to fit it. If I use this, I plan on opening up the intake on the Malossi on the outside to match the ID of the intake and then widening the intake port at the bore to 19mm.
Which should I use with this kit? Will the 19mm PHBG make a significant different in the power of this Malossi kit? The transfers on the Malossi kit are SMALL. Almost the same as the stock Puch transfers. maybe half a MM bigger. Will I be able to widen the intake port at the bore if it's Nikasil lined? Will is just chip off and ruin the bore?
If I don't use the 19mm with this setup, I'll just save it to run with a Metra 80 or Gila project that I have planned for a spare E50 that I have...
Thanks for your opinions and knowledge!
