Hello, I have a yy50qt-15 benzhou scooter, a retro star. I wanted to make it a little faster and I’m just facing a heat problem… which I can’t assess, Vario or hd. The scooter is throttled, ne Malossi Multi Vario, Naraku converter kit with new bell. So in principle not much. New open CDI is still in it. So, the Malossi multi solte I drive with 5.3g rolls according to the seller when I don’t use the white clutch spring that was included in the purchase. The 7g roll So, original was a 85hd. I drove now with 85hd and 5g rolls, is ok, bite lame in the suit… otherwise ok. Since I have a tuning set, I thought, you try out the 4.5g rolls. These put on the four-sticker even better, at hd 85! Since my scooter had bad values at the final speed, I assumed that I had a too small hd. That since already a 85er was installed, wu I was only eating now… ok, jet set was here, then I thought I’d take a different nozzle, let’s see how the scooter drives like that… Now my current problem is :-): I changed the 85hd for a 78hd, the scooter goes great in the pull-on and pulls up to 60/62. In principle this is the ideal setting for me, but my helmet compartment gets very warm. Almost too warm as I find it. Also the Vario is hot, the engine doesn’t stutter, runs clean, has a very good suit… it pa I had then converted, back to hd85 and the original Vario which was there at the time of purchase, with 4.5g rolls, it got me as hot as with the multi… Now I wonder, can an hd the carburettor so light up or is it because of the multi of Malossi? Spark plug image I still have to control, that is on the retro star so rarely stupid solved, so that I first have to dismantle the gabze box to come to the zk… look at now something small around the le Is now only the question of who is to blame, Vario or Hd?
