I'm sorry, but this is simply
not true. When asked a question, we need to give facts and not propaganda.
The truth of the matter is that the 390 and 361 will cut very comparably to each other. Yes I have owned and used them both. And the 390 will last a long time too. I used mine for probably 10 years. They are not built like junk.
The difference is in the following.
- The 361 is much more fuel efficient.
- The 361 has better anti-vibe using springs instead of rubber dampers.
- The 361 is much easier to modd, outside of a muffler mod. They both respond very well to a muffler mod.
- The 361 is easier to work on.
- The 390 has a magnesium engine mounted in a plastic frame. Some say it's very inferior. Myself, I find it very durable, there's no paint to chip off so they look nice a whole lot longer, and who cares if it's a little harder to work on. It's not likely to break and most owners aren't modding them.
The thing of it is, is that the 361 is not that much more than the 390. For that reason I would get the 361 instead of the 390. If you were talking a 310 or 290, the price difference is much greater.
