Just polish the ss pipes whenever required. I often use a piece of lightweight ratchet strap and Autosol. Quick and easy.

Did you tighten the axle clamp at the bottom of the LH fork slider before tightening the axle nut? If so, loosen the axle clamp and pump the fork a few times, before tightening it again.

Signal, your comment about reproduction cylinders makes me wonder. OEM Yamaha cylinders did have cast in liners that could not be pressed out, even if using heat. So if the liners would slip, then the design was altered by whoever made the repops. What the aftermarket SHOULD DO, both for RDs and...

Could be the holes were used or intended for springs holding exhaust pipes into slip fit spigots/ flanges. Maybe more common for 2 stroke chambers, but also used on some 4 stroke exhausts. Or for lockwiring. Could this engine have been used in a race bike?

Could I ask you with the early models for the width of the "pad track", measured from the disc OD to the inside edge of the brake pad? (The pads and pistons are 48 mm IIRC, so I expect this measurement to be around 50-51 mm, but would like to have it confirmed) I am ordering a new disc for my...

Sounds like you have one 18" rim and one 19". That would normally be 18" for rear wheel and. 19" front. The rim diameter is measured inside the flange, where the tyre bead sits.

Yes, both mine are fairly new, only used by me, always wound down after each use, and stored in dry and heated garage.

Aluminium, I guess? 2 or 3 mm thick? I have the same problem with my shock springs being too large in diameter for the stock chain guard. One more thing to look into....

Today is a wonderful spring day here in Northern Norway. Blue skies, still snow on the mountains and fields. Warm enough to have breakfast and enjoy a mug of coffee on my East facing deck/ porch. Even did some plinking with my CZ .22 rifle from the porch. Nice to live out in the sticks some days 😁

Yes, you are correct that the stock MC is 5/8"/ 16 mm. And that is far from optimal for a single caliper, at least when using modern, braided brake lines. (A smaller MC will increase the pressure, so more likely to "balloon" 70s style brake lines) But my experience, and that of many others is...

A good 13 mm MC should work perfectly fine with the 72-76 caliper with opposing 48 mm pistons. In fact, on my 74 RD350 with the exact same caliper, I use a 13 mm Brembo MC ("coffin type" reservoir), however with a ss braided teflon lined single brake line. The OEM brake light switch is no...

Did you try moving the tyre on the rim? Or even just notice the red dot (heaviest spot) or yellow dot (lightest spot) on the tyre?

XS500 tank?

Suddenly I found my long lost "Rewiring Round Tuit". Somehow it has been AWOL for way too long.... Anyway, the OEM -77 wiring harness is now in a cardboard box, together with the alternator, reg/ rect, etc. So now I have mounted the M-Unit, a new starter relay, and the Vape reg/ rect. And just...

Just set the tappets, using the clearance specs from the early models, on Howard Smed's recommendation. (0.15/ 0.30 mm or 6/ 12 thou.) The reasoning behind that makes perfect sense to me.
