250 sx trailer hitch

[mapyang]

I have a 1985 250 sx and I got a trailer hitch for it but no bolts, does anybody know the bolt size for this trike.
Thanks Drew

Pretty sure there 14mm head/10mm thread, pitch could be 1.25 or 1.50. Take one of the 14mm headed bolts out of your differential or swingarm mounts and try to thread it in. Those hitch threads are rarely used so you may have a bit of trouble threading in, best to tap them and clean them up or at least WD40. Gluck..
