best pull the cam chest off, replace the inner cam bearing with a torrington B-138 + new cam follower's & wheels , pull oil pump off check & clean ,pull oil bag + all oil lines & clean proper replace oil line better, check cam for wheel damage while in there pull pinion gear off & 620 loctite gear & new key on the min @least , i've done plenty of them best do her good the bike that is , your wife will cook you better & bigger dinner's for making her bike go better , sound's like a cam follower wheel has fallen apart & gone thru the scavenge pump that means you have too clean everything, when you change the oil on & EVBT leave the oil filter off & run a pint of oil out before you put the filter on this will flush out the old oil still trapped in the motor, make sure tank level is good
Yep, thanks Daddy Racer. I'll do the cam bearing while I'm in there. This year model had the plastic cage around the rollers so it's getting replaced. I'm going to lift the rocker boxes and check the rocker bushes. With no oil pressure for 10 K's, they're worth a look. This being the case, I'll reuse the stock pushrods. I can cut them out next time round.
Thanks,
Rick.
back in the early 80's my friend had a 1974 shovel , we rode from sydney too melb & back my friend goe's i changed the oil on the shovel before we left sydney & the bike is going that good that the oil is still clean as when he put it in before he left , the oil was still green ? well the old girl went 2,000 klms on what was in the motor only ( she had solid lifters ) but made it all that way , of course she had too be rebuilt but what bike could go that far on 1/2 pint of oil the pump wasn't working even before he left sydney
Checked the compression before I take the rocker boxes off. 135 front, 90 rear. Put 10 ml of oil in each jug and tried again, 140 front, 135 rear.
The jugs have to come off.
