You need to try them to see what they do. Just looking never got anybody anything.

Actually they probably would as they would delay the variator actuation being stiffer springs.

So have you tried the springs yet?

Like I said they were well worth the money back before I upgrade to a big carb and ported the engine.

Like I said, "When I used them they were good." And I still believe it for the dollars spent.

Well did you get the swap done and the ride in? So what happened?

Or just look at the plug, that will tell you before a temp change will.

Yeah they claim that but I have never seen it happen.

I already had my bike rich enough so I cant tell you if you will need to retune the thing after after the install.

Try moving your needle up one notch to cure the midrange stumble.

I trash canned the stock bystart and puy and manual valve on my nh80 and it is still working with a 24 mm carb with a 6 reed intake and different reeds. The only problem I have is that I can't remember where the report on it is, as I now have a Kymco Like 150i with ABS and there is no comparison.

You need at least new rings and a good hone job on the cylinder if you are lucky, otherwise you will need an oversized piston and a cylinder bore and hone job.

My nh80 accelerated better than stock and they added 2 mph on the top end.

The reeds worked on my NH80 until I upgraded to a 24mm carb and a 6 reed intake. Of course now I'm riding a Kymco Like 150i and there is no comparison.

They work on the stock Aero 80 cages and not on any of the smaller engine cages.
