Exhaust Derestriction

Dremel grinder or screwdriver and hammer man style)

A cool head and a patience

Exhaust restriction All Vinos ship from the with a restricting washer in the pipe where it bolts to the port on the cylinder. Some remove it. If your scooter 30mph top speed, you need to this annoying piece of believe me, you will never back!

Removal — the exhaust pipe by loosening the on the right side of the scoot ones that secure the to the crankcase [Figure 14 15] ). After are loose (do not remove them) you can remove the bolts on the actual manifold (under the scooter 16] ). Be careful when you do this, bolts are made of a very alloy to protect the cylinder and will break if you have to them. After you remove the bolts you can then remove the that secure it to the crankcase and remove the entire pipe.

When you look down the end of the pipe you will see a washer the diameter of the pipe. How you remove is up to you. I have heard ways that are effective, using a grinder/dremel tool to plain taking a screwdriver/hammer to it, man style. Just be careful to not the bottom of the pipe, if you flatten out the it will be kind of a waste you are even doing anything to it, this will restrict it [Figure 13]

Reassembly — Once the is removed you need to put the pipe on the scooter. This is the tricky The end of the stock pipe has slots as to holes and this makes it a tricky to reattach.

First the pipe in position and put in the top bolt to the about halfway, so the pipe is to move back and forth. go to the manifold and hand tighten the to the manifold making sure you have the threads on straight and it is not hard to turn the bolts, they go in easily. If you have to them or feel like it too much force to screw in, chances are you are cross-threading them.

If you do this you may break them off in the and that is bad news. It is recoverable but you added about 1-3 hours to work. Once you have the in the manifold pretty much all the way in leave enough room to shift it around if the main bolts don’t fit) go to the crankcase bolts and replace the bolt and hand-tighten both bolts. Then you can move to the again and tighten them a 10mm socket.

I don’t have the correct setting but just past the where it is flush should be if you run it a while and get some oil leakage or sound from under scoot, you may need to tighten it up a A Yamaha dealer or the official manual would have the settings if you want to be sure.

If you it — If you happen to break one of the bolts (don’t feel I did it), then you have a options according to your If you still have quite a bit of above the surface of the manifold you can use a of vice grips to take out the If you broke it off flush or near with the manifold then you need a drill that has and reverse settings and a drill/reverse bit set (for removeing broken from your local store.

Follow the directions that with the drill bit set to drill out the of the bolt and then use the reverse bit at spin to remove it. You will have to get a new bolt (I would getting a few) at a Yamaha When this happened to me The didn’t have these in so I just went to the local store and got some normal bolts.

With these you have to be extra careful not to thread the bolts in the manifold they are now the same strength you damage the manifold threads.
