Sounds like you might have a 350 motor in it. Have a look on this link, it appears that the 250s were OHC and 5 speed, whereas the 350s are DOHC and 6 speed.

simple answer look at engine number first 3 digits are the identifiers, punch then into computer as yamaha _ _ _ you will have your answer. More than likely a late model 250. If you cant identify it put the engine prefix up here.

MODEL ---------------- Engine Prefix
XT 250 sohc 82 ------- 5g4
XT 250 TL ------------ 30X
XT 250 TL 83 --------- 38M
XT 250 TN 85 --------- 57R,48Y
XT 250 TS 86 --------- 57R
XT 250 TT 87 --------- 48Y
XT 350 85 ------------ 55v
