My other passion...... 1998 Laverda SF 750S
mine
From the factory they were plagued with oil feed to big end issues - some machines only lasted a few thous km before they lunched - mine has done some 27k km - until I hit that roo at Boggabilla in May 2017 (but that's another story altogether)
Well a long story shortened...... have had the forks and monoshock reconditioned and intended to just recommission the machine and hope for the best...... well, then a sure fix was suggested, economy in numbers so I stripped mine for the fix and found this.......
it's pressed crank with needle roller mains and big ends - pressed apart
Houston, we have a problem....... it appears that had I not hit the roo I may not have made it home anyhoo....
