Title: 50cc to 80cc
Post by: Aaronk on January 07, 2011, 07:06:33 PM
Is it worth upgrading to 80cc

The head doesn't come included will the current ones which are on be fine?

If it is fine how much will it increase in speed?

I also need to do the drive boss bit is this part the correct one?

Me my self I would just keep it a 50 and do the boss cdi and jet. too much is asking for it later.
but if you need a muffler anyways go for it.

The advantage of a LeoVince aftermarket exhaust is that they won't rust out. 

Those of us who ride in winter and deal with road salt find that the OEM muffler rusts out after a couple of years.

I'll be going with one probably later this year.  Not going for performance increase, just want something that will last.

How big of an icrease are you looking for?  I spent over $500 US on parts and labor adding a bigger jet, UNI filter, 72cc upgrade...

I only got about 5-8 mph increase, maxing me out at about 38-40mph gps verified on the flats.  If you need 15-20mph increase then you need a bigger bike.

They rust out even without salt... and after a couple of years, it is time for a new scoot anyway (and if you have 50 cc, even more so. :) ).

After 2.5 years I'm just getting my scoot dialed in. 

Maybe after 2 years it's time to buy another scoot so you have more than one to ride?
Title: Re: 50cc to 80cc
Post by: Rianna on January 09, 2011, 01:02:05 AM
I'll go along with that!! So which one you gonna buy next, oswaldters?
Title: Re: 50cc to 80cc
Post by: oswaldters on January 09, 2011, 01:06:27 AM
I'll let you know when I get ready to get another one - in about 2 years!

Who knows what the 50cc line up will look like by then!

Definitely would like to have the second one, that way when I'm working on the other I would have something to ride.

Exhaust can will not rust from outsidein 5 years. However, regular steel cans used by Kymco will rust immediately after you paint them, even if you use thermal-resistant paint in multiple coatings. Rusting is usually superficial and not in-depth.

However, the exhausts do burn from inside and usually after 25-30.000 kms you will notice a change in sound, meaning that internal chambers have been burnt and destroyed. Your mileage may vary, but usually after 25 and 50.000 kms it is time to replace exhaust on 4-stroke bikes and scoots.

That's why I have three: 50 cc 2 stroke, 125 cc 4 stroke and 250 cc 4 stroke. :)

That's where the salt comes in - my muffler is still solid, but the pipe is what is rusting out badly from the outside.
