[replyingto=chanoarg]chanoarg[/replyingto]Yes you should replace the gaskets. You can get the engine number from under the cvt area and find gasket kit for it. Do some research on which kit you need. Yes replace the gasket for the exhaust. It is not fun after waiting for parts, then realizing they are wrong. It helps to take it apart, measure, then order parts.

Yes chain is tight. I installed it, rotated several times til it reached the tdc mark, then i installed the cam and tensioner.

I am concernedit could be a bad oil pump, or possibly bad bearing on camshaft.

Wilds- good point. I will switch the fasteners and use a little jb weld to make sure it stays put. Thanks

Sailracer- glad u like it. I had a round uni previously and it began to fall apart. It is also not good if you get caught in the rain with the round uni... luckily it only happened to me once. That is why i was inspired to attempt a new setup.
I also noticed when I had traveled to italy that they all had stock air boxes and the reason could be because they ride in all seasons.

Wilds- you have a very good point. I thought about that and figured that if I reverse the setup...the fasteners could get sucked up.

I may put a small screen over the intake hole to prevent issues...I have it from the stock filter setup.

The other possible solution is to put bolts with lock washers.

So this would be my version of a cold air intake that would do better in the rain than a round uni. This is definately not a cold air intake, but hopefully a way to maximize air flow on the stock box.

Here is my second attempt at the custom uni in my stock air box. My first attempt involved a broken filter element from attempting to use a staple gun on my plastic filter.

I made a metal version of the filter element.


The inside view-


I used the metal backing from the original filter and attached it with fasteners.


I cut the two holes like bluefront did in the previous link.


I like the setup so far...it is quieter than a round uni filter but still has a slightly deeper tone than stock.
I will test it for a few hundred miles and see how the spark plug looks. My first plug read was not rich... but it was only after a few short rides.

Happy modding!

Do you have 16" wheels?

Because the one i have has only 2 bolts on the valve cover. There are not many options for upgrades on my scoot.

Hello everyone,

I just wanted to say thanks for the info. I ordered the gaskets from bms because i knew they would be correct. I installed them and no more leak.

So don't make my mistake and try to reuse the metal head gasket...it won't seal.

Everything is running great after my rebuild!
