Has anyone used this product successfully? I have lost
top end speed - from 40 mph to 30 mph - on my Yamaha Zuma and have
done all the usual things. I have replaced the spark plug, put in a
new belt and replaced the roller weights. I have been told that it
is
probably a clogged exhaust port.

I really doubt it.
It's much more likely to be clogged baffles in the exhaust *pipe*. I'd
also check the condition of the air filter.
And how many miles has it done? Two strokes are heavy on piston rings
and it may need a new set. If it's very high mileage, maybe a rebore
and/or new piston too.

AOL - most of this stuff is somewhere between snake oil and pretty
useless.

This gets my vote too. Collapsing baffles took the top speed of my son's DNA
from 50mph to 35mph. Nothing else is likely to have such a significant
effect in one go.

Unless you're DatesFat and think "there's something wrong with the
transmission".
