Hello, I once again enjoyed an 80s, since I drove an MBX80 back then (25 years ago), which is a bit too small for me, I used an RD 80 LC2 this time. I was busy with tuning at that time, unfortunately the whole thing was rather limited to buying, installing, driving, so I really am not a real tuner. My RD should now be a little bit reinforced, so the selection is not so easy for me. It gbt enen 110cc set of malossi and a 110ccm Set of Polini. Malossi is conventional grey cast iron, Polini is aluminium/nickasil coated. A racing exhaust is eliminated, the volume of which I still have good in the ear (proma) from then on! Unless there is a quieter version with ABE etc. The carburettor question…unfortunately I can’t remember what and how much the conversion to a larger carburettor Ø26mm, in connection with a displacement set, so I am now all the more unscathed if this must be overhappy…the Consumption also plays a role today, at that time I filled up almost fully for 5DM… the same tank would cost “only” 15 euros today… Oh yes, the whole should be as suitable as possible, that would be quite important to me, if, for example, another membrane etc. should slip through, so I am not mega-small. The everyday suitability should be given. A lifetime, with intensified gear type, of 10,000km should be given. I hope a Vmax of approx. 130km/h and a Vmax of approx. 130km/h and a Vmax of approx. 130km/h should be given. “permanent” speed of 120km/h should be possible, without which the white flag stretches to me after 20km of the cobs. Greetings karl
