      ..... except that requires breaking the chain, harder and much messier than just pulling a muffler, in my opinion anyway.

      I do, but they are the N.L.A. MAC headpipes. They swept up on the ends at what I think was the perfect angle, high enough to clear the...

      It seems Yamaha put a little more time and effort into making the first year 35mm fork damper rods a bit nicer. They polished them up...

      Not real critical I guess. The forks may top out occasionally on the road and every time you put the bike on the centerstand. You'll get...

      Unfortunately no they won't. The headpipes on my '78 are the MAC brand and what MikesXS used to sell before they had their own made up...

      You're going to find the '77 damper rods differ slightly from the '78 and newer ones, mainly at the top. The holes are the same so you...

      I've never added a preload spacer to the aftermarket progressive springs, didn't need to. I think they're a little stiffer than the...

      The Euro bar bend is my favorite and I put it on all my bikes. Because of the way the ends droop down slightly, I think these are about...

      5twins replied to the thread Royal Enfield Interceptor 2019.
      Yes, I heard the fuel system sort of "self-tunes" itself for minor mods. That's pretty cool. Are the bends that angle the mufflers out...

      5twins replied to the thread Grease vs antisieze.
      Well, the old BMW mechanic's "blend" was moly grease mixed with anti-seize. I have a jar I made up that I've been using for years.

      5twins replied to the thread Royal Enfield Interceptor 2019.
      I might swap in the new relay, to an important circuit like the "Ignition", and carry the old one as the spare. It would be interesting...

      5twins replied to the thread Grease vs antisieze.
      I think with that much movement, I'd go with grease. I only use anti-seize on non-moving parts (threads or the bolts themselves), or a...

      Yes, when I replaced the carb boots on mine, all I could get was the ones without vacuum barbs. So, I drilled them and pressed barbs in...

      I've never had any issues getting the carbs in or out. I put the bike on the centerstand, straddle it and grip the sides with my legs so...

      I would say 18ga. wire is fine. LED signals don't draw much and signals are only intermittent use besides.

      What about cam chain tension? Is there an automatic tensioner or do you have to manually do it like on our 650s?

      Looks like you've got it squared away now. Since the advance backing plate is just raw steel, you'll want to keep it lubed for...
