2005 factory ditech with newest engine(europe) now it is totally de-restrictied and the strange part is that i know that the gameboy tune has been done since professionals helped me.
It feels like the middle segment is good but the low and the high speed is terrible. It takes ages to reach 65 in "plain" grounds.
So here it is: I had a 2006 before and it went 54 km/hour without any tune at all, this one is the same model, but manufactored 2005. Original it goes 48 km/h but the issue is that it is bluddering at low rpm and sounds strange, but when you use the gas it goes pretty well but not as well as the last ditech factory I owned.
So I gameboytuned it and the topspeed became 50 km/h and the acceleration is a bit better, but still it is bluddering at low rpm. If you try to start it you need to hold the left breaking-bar and it goes for like 2k rpm until 2.5k rpm and if you stop holding that bar it dies, if you hit the gas to early it dies. So easy to say you cant just start the engine and let it go by itself then it dies. Even if the engine is warm, it is the same thing. And also if you just stand still a while after driving for like 30 minutes it dies itself also if you don't gas until 2k rpm and up.
Now the variator spacer is removed and the topspeed of course increased to around 65km/h flat and around 70km/h with a little downhill; also note that this is engine ONLY has traveled 6000 km and has been used fairly without tuning and also been handed in to the aprilia-partners in november and after it was handed in. The previous owner experienced this error in the summer and he asked the dealers to fix it, but his receipt doesn't tell that they have checked what he asked for and I called them and they told me they didn't knew about this error.
Please give me a few ideas what I should do, a compression test I don't think it will help since it is nearly impossible that the engine is broke. I understand that it has something to do with the engine/the fuels or something.
I assume there are some errors in my grammatic, I wrote this fast and english is not my primary language. Hoping for some help!
