Title: Kymco ZX50 - Accelerates and then feels really sluggish
Post by: Mikrontiputtaja on July 23, 2020, 08:40:31 AM

Hey. I have an 2004 ZX 50 with emptied original exhaust, Malossi's +30% variator springs, 4,5gr rollers, skipped CDI.

After i accelerate then it kinda "slows down" 50% and feels really sluggish. Do i have too light rollers?

Okay I am not talking from any experience in the things you say but it reminded me of a Vacuum line problem I had so I thought to suggest to look over any vacuum lines looking for worn lines or leaks.
Good luck.

I did drill the vacuum line thingy with a 16mm.

Interesting. Like I say I am not experienced in what you say but I found a line that worn a hole in it causing me a lot of problems.
 Hopefully Stig can solve this for you.

When you say you drilled the vacuum line, what do you mean? I find that a little worrying
