OW01 – wrong!

Old Bike Australasia - - BLOW YOUR OWN -

The ar­ti­cle about the Yamaha OW01 (OBA 48) gets a few things wrong in the spec sec­tion. Where it men­tions 2 in­let valves and 3 ex­haust is back the front; 3 in and 2 out. They run 320mm front discs; at least mine have (not 280mm as in the ar­ti­cle. 280 were the FZ’s I think). They have a con­ven­tional 43mm car­tridge fork (not “In­verted” as in the ar­ti­cle). The two ring pis­tons I as­sume refers to 1 com­pres­sion and 1 set of oil con­trol as they only have one com­pres­sion ring to re­duce drag. I sold one of mine to a col­lec­tor in SA a few years back. Kind of re­gret it but it was just sit­ting in the back of the shed and be­ing wasted. The other one (not much orig­i­nal stuff on her) is nearly back to­gether af­ter be­ing left in the back of the shed as well (bro­ken starter clutch).

This was one of the Marl­boro bikes (I have the fair­ings) but now has an FZR1000 en­gine (2kg of the crank etc). It’s run­ning again now and should be road­wor­thy in a few weeks. Look­ing for­ward to giv­ing a few of the newer bikes a sur­prise! Pete Mont­gomery Via email
