glowing muffler

[Pillen]

Hello, I have a 06 Laser r5 with 2800 miles and the muffler is glowing red hot but the pipe before it is not ( I can touch it) it also hesitates of the line. Thanks for any info

[harry]

you might be too rich 
sounds like fuel in the muffler burning
what does the plug look like?

The plug looks normal (a brownish color). I was told by a friend that the muffler was bad but, I wasn't going to buy one if that wasn't it. Plus i'm having a hard time finding a performance one for that engine.

heres some pipes that fit morini motors:

Thank you for the info on the mufflers. Would I have to upjet or change the airfilterwhen adding it? and what about the rubber hose thats on my stock one that goes to something under my seat?

[harry]

Air filter is a option.

Up jetting is a must with pipe &/or filter.

Plug it with a bolt or something.

Remember your scooter will get real loud when you put on a filter
some guys think it makes more noise than the pipe does.

the stock carb is a 13mm  with a #60 main jet.... small jet for a 13mm
for comparison vinos have  65 as stock in a 12mm carb.
the 60 is part of the restriction.

What about the rubber hose off the pipe? Is that something that I just leave off and what does it do?  Sorry for all the questions I don't know to much about the 2 stroke motor and don't want to blow it up. Thanks again Harry for all your help 

[Pillen]

Do they make a better shock maybe something adjustable or oil filled for the Laser?

[harry]

Plug it with a bolt or something. it is part of the emission control
basically it sucks the tank vapors into the exhaust .

are you sure the shock is not adjustable ? it shows it is in the parts
books

I'm not sure. I wasn't given a manual with the scooter. Thank you for the info on  the rubber hose I will have to do that.

[Pillen]

double checked the rear shock and there was no adjustment that I could see.

heres the link to your owners manual...
http://www.cobrasales.com/docs/TGB%20Laser%2050%20-%20Owners%20Manual.pdf
and the service manual to all the 50cc TGB's...

all the other 50cc TGB's have a adjustable shock yours should too unless its just too old
i think if you look real close at the shock behind the air box you will
see a funny kinda stepped bunch of half circle cut out  deal at the
bottom of the spring,  that is the adjuster.

I just took my air box off and I seen the adjustment steeps.  Thank you for the manual it will come in  handy.

[Pillen]

The little screw next to the big knob on the carb. is that to richen the fuel or does it change the air? And am I safe to turn it counter clockwise to richen it up?

[harry]

yes its the mix screw .
adjust it and check you plug for good color.
 you might want to remove the tiny #60 main jet and goto
a #65 or so.
