    Yamaha 1981 LB50 PH Chappy resurrection

    Well Gang, finally got that engine jolt in hi gear all figured out & fixed. It turned out 2 be the shifter, it wasn't keepin the shifter rod fully engaged in hi gear, allowing the trans 2 slip in & outta gear @ hi speed, so I took it apart @ bent the detent plate & put a washer under it 2 keep...

    Yamaha 1981 LB50 PH Chappy resurrection

    Hi 67, there was no pitting on the points, but there was a small hole in the center of the contact area, I think its supposed 2 be there tho, I already put the cover back on, I don't think those readings on the coil would affect jus hi gear & not low gear when they both rev the same? I jus think...

    Yamaha 1981 LB50 PH Chappy resurrection

    Hi 67, I found the xploded view of the trans in the manual ya gave me, but now, I don't think its the trans as I don't see nething that could fail cept the spring that is keeping the shaft in the hi range position. I'm starting 2 think its a hi speed ignition miss? I already cleaned the points...

    Yamaha 1981 LB50 PH Chappy resurrection

    Hi 67, maybe, but I think I saw a couple on treat's site that have the same dimensions & I don't have an xploded view of that gearbox tho IDK if the spring has gone soft, it didn't do that the 1st time I had it out either-------twosmoke

    Yamaha 1981 LB50 PH Chappy resurrection

    Hi 67, yeah,it does rev in 1st w/no bucking, it jus does it in 2nd gear, intermittently tho. it sounds more like it slips in & outta gear, bcuz it revs higher between the cutouts. could it be the gearshift rod moving outta engagement? I don't think the clutch is slippin, when it goes, it pulls...

    Yamaha 1981 LB50 PH Chappy resurrection

    Hi 67, well I had the scoot out last nite, that sprocket fit like a glove & only lost 6 MPH top end, BUT another prob, do they ever end? while in 2nd gear, the engine seemed 2 buck, like slippin in & out of gear, it would rev then skip then bang back in2 gear, what could this possibly be...

    Yamaha 1981 LB50 PH Chappy resurrection

    Hi 67, yeah, I have a multimeter from the now-defunct radio shack. do I jus start the bike & measure the voltage from the red wire 2 ground? I think the fully charged battery will stop the bulbs blowing, that battery was nowhere near charged w/only 1 cell filled, so I'm gonna try that 1st, if...

    Yamaha 1981 LB50 PH Chappy resurrection

    Thanks 67, well, I guess I screwed up twice, I shoulda checked the levels when I got it & I shoulda shut off the ignition switch when shuttin it down, but there's no xcuse 4 fillin up jus 1 cell & sellin it. I'm goin back there 2moro & either havin em add the missing electrolyte & chargin it...
