Can Somone recommend a good non reed intake?

[Rusty_Nail]

I'd like to get a CNC intake. I understand they seal better and perform slightly better than the stock one. Would like to get one that can connect a bigger carburetor. My bike currently tops out at about 37 with 32t sprocket. Would like to be able to get it at least a bit over 40 without having to to advanced stuff like crank balancing or messing with reeds. I have a mostly stock unported Samger 100cc engine. Any help is appreciated.

A basic kit with all stock parts should be able to hit 40 mph with a little modifying and some tuning.

I would ditch the small sprocket & go back up to a 40t (so the engine will have more pulling power).
Next I would gut out the muffler & do a little port matching in the intake & exhaust manifolds, & then I would re-jet the stock carb. That should get you about 45 mph.

I will definitely look into the larger sprocket. As for my muffler, its an MZ65 clone. When it comes to the port matching, Ive never done it. Would there be high risk of ruining my cylinder? I've been wanting to try a 72 jet in the carb, but can't seem to find it. All the listings I've seen for jets don't have the 72 in them.

The port matching is most important on the pipe side. There needs to not be a step that the gas hits. You won’t ruin the bore if you don’t touch it. Perfect match is best of course. But I wouldn’t match to a muffler if I was going to run a pipe later (match it to the pipe).
