Im new to this forum. My name is Micke and I living in Sweden. I just bought a Nsr 250 se mc21. Havent owned a 2-stroke for about 20 years
It dont started so good, after 10min in my first ride the bike died
the bike was a bit weak from the beginning, high revs to take off. So i think it was damaged when i bought it.
My problem is that i have H2 barrel rear and L1 in front, but they have compitable top. R top for R barrel and SE/SP top for SE/SP barrel. The L1 is the damaged barrel. I dont understand how I know which piston size I need for that barrel? Some people says i should have a, b or c stamped on the barrel, but i dont. Just L1 and a long number "1ds1L15".
Hope you understand my bad English
Kind regards
Micke
