Technical questions

[lsuarez011]

First of all, thank you very much, the forum has too much good information. I am from Colombia. I have a Kymco Agility 125 with digital tachometer model 2016, the bike is excellent.

I have the following modifications installed: Bore to 150 cc. Clutch with red springs (2000 RPM).

I would like to know, you have mounted PWK type carburetor or its better use a 26mm carburetor? what weight of roller or slider can I use to have a performance more in line with the strength of the clutch?

Thanks

Welcome here!
Concerning carbs:
both types are available in 26mm, which, correctely jetted, seem to be enough for 150cc
-with a PWK carb you might have a little bit better performance
-a CVK carb is more reliable and has better fuel economy

There is no magic formula which is spoken over a carb and makes it work wonderousely.
Only road testing with different jets is a way to success.

About roller weights:
Again no easy way to find for YOU the right
a) weight
b) shape
c) performance
..as a start leave original rollers in your CVT and testride..with your carb of choice

You are not happy with your taking off from start
- try lighter rollers
You want a more quiet cruising,
- try heavier rollers or Dr.P gliders

Maybe watch this link for some inspiration..

excellent information, I really appreciate it, I will look for the CVK. but what size do you recommend, go to 30mm or 26mm?

With respect to the "rollers" I will try something lighter, currently I am opening at almost 4500 RPM, I am looking for something that opens at less RPM.

Best way would be to try it on the road with both.
Aftermarket pieces are inexpensive, even I think 26mm are enough for 150cc.
