bit of a fan of late '60's to late '70's yams but in saying that i had great fun on the yz465g but interest goes back to when we had a guy working on the farm & had a 500 matchy--took me up the road age about 10 & let me steer it [that was it for me]--down hill from there haha. Me age 67 now, long sad story of blown up [over hotted] British road bikes turned into scramblers RE's Matchy Bsa [big bikes] before that was 125 banty, 125 barnett, 197 barnett [hit a ticket box at the racecourse [horse] & turned it 180, took the fergy to turn it back & cost me 20 pounds to fix it [ticket box that was] bike was poked. Had transfer ports cut completely open by memory just a big slot covered by the piston, plus full circle flywheels--went like hell at the time. Anyway, story telling again. Cheers.
ps, wasn't my fault i hit the ticket box!!, was racing a mate on his B31 on the tarseal narrow access road in the racecourse & was mossy where the trees over hung the road--not my fault i say. Like the time i was racing my mate on a metal road & my matchy RH footrest ripped a vanguard car open like a tin opener & knocked the rear wheel out of the slots [rode it home] was my mates fault for racing me ehh--stuffed his B33 though & cost us lots to fix the car [bloody sunday driver--'uh i'm one now'--bloody trail riders!!]
