Oh right 125 miles isn't too far. I haven't ridden an rs50 but i have heard af1's and the older single swing arm model rs50 are better to ride than the round shape ones.

Well I have driven both and they really are a pleasure to drive. On the other hand on the Rs50 old model I had a slight bit of wrist pain after a long drive ( let's say about 30km) but that could just be me. When I had to pick up my new model Rs I had to drive it back and that was about 120kilometers. I didn't have any pain at all, in fact I loved it! I guess it's just a matter of preferences.

I've made 200 km's on one day with my af1, when i got back i didn't have any pain, blisters or anything... I wasn't even tired
the saddle is comfortable, the position is much better for your back (more upright), and it's just more of a touringbike than a sportsbike... RS50's are more sportsbikes, the reason why you had a soar wrist was probably because you had your oil-pump connected... i've shut mine down because the throttle becomes much lighter and more comfortable

Hi all, i just thought i would ask a question here rather than create a new thread/question in another section.

I would like to know what jet sizes for all the 3 jets would be a good set up for my 19mm phb/g carb on my 70cc polini aprilia af1 to get the most speed,revs and power from what i have at the moment (setup explained on here i think)?Thanks for the help.

it's different with each engine... you'll have to try differant setups

ok, i think i will just change the main jet anyway.Thanks.

Hi all , does anyone know what the rs50 arrow exhaust is like and if it will let my aprilia af1's engine rev to 12,000rpm? Thanks for the help.
