E.g:
> not so lucky and got a "ru" ending? check what vowel before the "ru". it it's one of -aru, -oru, -uru, then it's also a godan verb.
Wrong: 煽る (aoru) is ichidan: 煽った、煽りたい、煽らない、煽ろう、煽られる 。。。

I don't have a problem actually conjugating and don't have any tricks for it.
It comes with vocabulary. Once you have a vocabulary that contains enough verbs to hit all the cases, the rest just land in one of the cases by example.
If you know 泳ぐ (oyogu) very well, then even though you don't use 仰ぐ (aogu) very much, you just conjugate it intuitively like oyogu.
When you're speaking, there isn't enough time to go through a roster of rules.
For all that I'm not totally sold on this article's idea of "stems" and "suffixes", I think it does a good job of avoiding this pitfall and correctly explaining the groups.
An important aspect of vocabulary that informs you about verbs is knowing the nominal: the noun-like stem. Like when you consider 帰る, you know from your vocabulary that there is no noun-like word "kae" that is just written 帰. You know that "homecoming" is not "kae" but "kaeri", 帰り.
So from that alone you know instinctively which way it conjugates: らない、れない、りたい、った、って、ろう、。。。
And a big source of learning the stem is ... japanese polite speech with -masu.
This is how children absorb what the stems are: hearing all the verbs in -masu form.
For instance, I think that every single verb that ends in "-rimasu" in the polite form (other than just arimasu?) is a godan -ru word. Drop the masu and you have a -ri stem, which implies the word is -ru, and conjugates godan: -ranai, -renai, -ritai, -rō, -tta, -tte, ...
Not quite: https://jisho.org/search/%23words%20%23v1%20%3F*%E3%82%8A%E3...
None of these are ever other than ichidan? If we imagine a -riru verb that is godan, it would have to go to -ririmasu.
That sounds like something only a ditzy weather girl called Ririko would say, for a gag. :)
FWIF, the "#words #v5r ?*りる" search does come up two hits:
The first one is 手を借りる, which is a classification error; it is a compound verb that conjugates exactly like 借りる by itself.
The second one is a curiosity: ラリる -- to get high on drugs. Supposedly godan, so it does give us ラリります, etc.
Wikipedia page on it with some etymology/origin notes: https://ja.wikipedia.org/wiki/ラリる
Well, apologies to Ririko there!
