noticed a pool of oil under the 250 last week and after ripping off the fairing i seen a crack in the rocker cover. after taking this off i found that what i think is the timeing chain has ground away and pushed through. am trying to find out if replacing it would be a home job for my brothers and i?
by the way its a 1990 zx2r model a.
thanks

(will upload pics when i find the cable
