I need a option By puddle jumper (Read 1,178 times)

After thinking about it for a few days I am not going with a 80bbk till the scooter I have has some miles on it but before that happens I want to replace the air box with a k&n filter 35mm size but before I do so there is this that is attached to the air box:

I've read threw many post and it has something to do with the vent for the gear box, is this something I can safely remove and set aside and if I'm wrong I will plan a few other mods beside replacing the box. The others I had in mind was a new plug and coil, replacing the stock clutch and springs(1500 rated springs) and I also just for appearances open the end of the gear box to expose the clutch. My scoot runs fine at the speed I like and all of these mod's is just for maintaining performance's and not trying to blow things up. Oh before I forget I am going to if adding the new air intake up jetting the carb with an #88 main. I anyone see's a possible problem with what I want to do please feel free to send me a message personally or voice it here.

Sounds like you've already got a handle on it. If you were into a stock air box mod, you're probably better off just drilling a couple small holes in the case, rather than to remove the vent tube.

All the other mods you suggested are good ones. I'd add a more reliable CDI, than the OEM stock one, to the list. That way you'll have both a working coil, and CDI to go with the original belt you'll also replace, with a better quality one, before it breaks, so you can use it for a back up as well. Most service stations have an impact wrench that will remove the variator nut for you, but they seldom have these belts.

Do change that plug and keep it with you too, for the same purpose.

#88 main jet should be fine for tuning the free flow filter, but A/F mixture can be touchy. A $30 dollar jet kit from Enviromoto, or something similar, is money well spent, and will make sure you have the right jet you need now, and down the road if you do invest in the BBK.

When you replace that belt, when you switch out your contra spring, pull the variator, and inspect. Find out what size and weight rollers you have presently. This will allow you to know which direction you need to go with them to tune the variator to the new clutch set up. The 1500 spring should give you better take off and hill climbing capability, but may sacrifice a few mph on the top end.

Changing the variator out for a better one, and different weights, or even sliders, can further tune the transmission out to where you can gain back any loss, and in some cases even jump you a few mph, over all.

Venting of the CVT case is a nice mod, lowers temps significantly and adds to belt and transmission longevity. It's also one of the few mods you can do w/o having to change something else to accommodate or compensate for the benefit it provides.

Almost w/o fail any one mod will lead to another, and so on and so forth.

That is sort of the goal we are shooting for when we mod and tweak these things into shape. Good luck, and keep us posted. Lots of help here and none of this is rocket science. You can do it all, with some help and good measure of patience.

If I were to switch the plugs would a standard IGK rather than an the expensive iridium plug since most of my plans expressed above are stock rather than "high" performance?

[kr10k50]

I wouldn't cut corners on the plug. Go with the NKG Iridium. Well worth the a few extra bucks. Same with Oils and Gear lube. Get the best you can afford within reason. Scoots run on such small amounts of both, they need to be good quality and changed often.

Back to the plug again. There is only one to depend on, and it doesn't get a new one, at every oil change. It's sort of like spending a few extra dollars on a good saddle.

You'll ride on those extra bucks all day long.

Iridium is marketing hype... IMHO

If you want a spark advantage use a side gap plug

www.sr20-forum.com/naturally-aspirated-all-motor/16898-how-side-gap-spark-plugs.html

I use them in everything from chainsaws to ultralights. They work very well in scooters and you
can run a bit rich and not have any plug fouling...

[puddle jumper]

say what you will personally I've weighed all my options and I'll stick with a "regular" plug till I decide what I am going to do next. Thank you for all of your efforts and the opinions will be well remembered.

[kr10k50]

I've never heard anyone badmouth an iridium plug before....well outside of the local Kymco dealer, who also throws away any incidental body parts, screws, nuts, or bolts he might find to be too much of a hassle to take off and replace more than once on a customer's bike. That's pretty good company.

You will notice a difference and I don't think you'll be disappointed. I seriously doubt I'll ever go to that much trouble to prep a plug. But who knows what the next blizzard will bring. And it's nice to know there is an option. Good Post!

If your still running the OEM china plug, however, you're looking for trouble.

>>I've never heard anyone badmouth an iridium plug before

I'm not bad-mouthing iridium plugs, they work and last longer than a standard plug.

I replace my plugs at 1000 mile intervals, so what is the big deal. I can buy 2-3 standard NKG plugs for
the cost of one iridium...

I have never seen any advantage to using iridium in a single cylinder engine...

[kr10k50]

Well I'll certainly defer to the experts.

I'm perfectly happy with my plug.

I love my Iridium plug too! It does make for slightly quicker starts and I feel a SLIGHT difference (more like hear) at high speeds.

but with winter coming isn't the iridium plug made more for warmer climates?

I don't see how? The iridium plug burns hotter than a regular plug.

It "burns hotter"? Not really.

[puddle jumper]

I guess I was thinking the opposite on that one
