Cruisin' Guzzisti
Hi there , being sorta new to Guzzis (but not to bikes )I thought I'd check you out .I read with interest the posts re gear boxes.
I guess a bit of history is in order
Brother in law bought the bike ( a 1974 850t) as a non runner and chucked in a shed where it languished ( and rusted ) for 10 odd years. Every year at family meetings I accused him of wilful neglect of a motorbike and the like , anyhow , I think more to shut me up than any real wish to see it going, he gave it to my wife ( the bastard :twisted: :lol .We had to use hedgecutters to free the bike from the jasmine that had grown up thru everything .... on the inside of the shed !
apparently the guy who owned it spent a bomb rebuilding the motor, which only went a couple of hundred yards and stopped. ( recept dating 1992 for over 3k were eventually given to me ).What I found upon dissassembly was indeed a newly , fully reconed motor ............ that had been horribly botched. The heads were ok, the cylinders had been sleeved and fitted with t3 pistons which had not been given the required clearance and had siezed ( the hundred yards ) , it gets better. With this thing in bits on my bench I see that the "new" big end shells were lookin sad, so was all the angle grinder marks on the end of the crank pin ( opposite end to the screw in plug ), the plug was removed and it was noted that the void in the crank pin was full of abrasive crud from where the crank had been ground 30 thou and not cleaned out .Attempts were made to ballance the crank, ( when I 1st started the motor it vibrated so bad it shook the relays out of thier holders ). The guy who re ballanced the crank said it was 90 grams out.
New pistons ,berrings , crank sorted and cylinders honed, carbs kitted and a dyna module and coils and all is good ,motor wise The frame ect was all stripped and painted . No attempt was made to keep it original .all the chrome was to rusty to save so it got painted . suzuki blinkers yamaha switches , chinese mufflers . Now its the gearbox's turn . Posts advising a new return spring and a reshimed selector drum explain some of my symptoms , but I fear there maybe a few knackered berrings in there too. Wildly different to my Dukes, but Im really enjoying a change ( getting older too, plus nearly killing myself , actually it was the guy in the car, and Im slowing down a bit )
