what do you mean a lemon
Your problem is not so unique, it happens very often with new vehicles.
When I bought Agility, its disk brake was greased for some strange reason and the forks were unscrewed.
Both things are VERY dangerous. So, the first thing after purchase was - going straight to the shop.
My People had factory error in engine casing and very soon engine casing had to be replaced under warranty.
13 years ago I bought a brand new car that consumed 50% more than it should (I had another similar car, I gave this one back to the shop for testing, they proved it etc.) However, they were not able to fix it, and I endured this for 5 years and then sold it away.
There are a number of similar horror stories about much more expensive things than little bike or entry level car I had: it happens with sports and high class limos too.
Last year I bought a new car and I do not have big problems with it, but it shudders when starting in 1st gear (some issue with injection probably). During 1st service the shop did not do anything to fix this because when they read ECU memory with the tester, there is no error logged and if there is no such error, they do not investigate further.
Unfortunately, we live in a consumer society formed around debt and things you could have expected 30 or 40 years ago buying durable goods do not apply anymore. This refers to warranty, customer care and many other things.
I know you will not be consoled by my words, but I said many times on this forum that Kymco is not a hyper-quality bike as it is touted to be. Far from that. The problem is that I do not know what should be the premium brand anymore, which brand would be better? 20 or 30 years ago there would be a reliable scale to determine that, but not anymore. However, from my own experience and driving Italian and Chinese vehicles, it is much, much better, but not so good that it does not have flaws like you are experiencing.
p.s. "A lemon" is a synonim for "a dud", badly assembled product.
