De-Restricting 2008 Honda Met

[TortugaTomasa]

So I think I want to de-restrict my Met but I'm not sure how to do it as well as what results should I expect to see and is it worth doing it? Have any of you other Met owners done this, if so what did you experience and would you be able to tell me how to do this?? I'm sure it's not too difficult, especially since I have the skillful Senor to help me, but having an outline of directions is always helpful.

i would love to help you out but ive never worked on a met on a zuma you get out the dremmel and grind the crap out of the throttle cam and you get better pickup a bit more top end and your mileage drops off a bit

I removed the stand lock latch, Yellow handle with Phillips screw

I removed the 4 bolts holding the seat/storage box down

remove the seat/storage box and set aside.

I got a good source of light to really see what I was doing.

The restrictor is a metal plate with a green gasket attached to it at the manifold, parts 11 and 12

the two bolts, parts 18 need to be removed. their is alot of stuff around them that make them difficult to remove. This is where you just need patience. I used an open end wrench and could only turn them a small amount each time before having to readjust the wrench. Eventually they will come out. One of them was easier than the other.

Once bolts are removed, I used a pair of needle nose pliers to hold the exposed edge of restrictor plate and attached green gasket and it slid right out.

You do not have to reinstall the green gasket, as the manifold has a oring seal, part 14

put the bolts back in. Get them both started before tightening them up. I had to jiggle the manifold around a little to get the bolts threaded.

hope this helps, I noticed better performance after a couple miles of riding. Definitely worth doing.

no problem , glad I could help, Others have suggested removing the carb. to get at the bolts easier, but I found you dont have to do that, plus some of the screws to remove carb. are on very tight and strip easily.
