Thank you for the reply.
Beta rev 270 2002/03 Stock(fresh packing) new rings.
Beta rev 80 07 Stock (1 ride old)
Just want to get a basis to work from as i suspect it will have coastal jets fitted and we are fairly high at around 5000ft.
Ie recomended needle, main and pilot so that i can then get them and a few around them and start the process.
Anybody have success in dyno tuning a trials bike ?
