Title: AMAL 376 carb for my 1959 Chief
Post by: bullethead63 on March 22, 2013, 02:01:57 am
Just picked up a GREAT deal on a totally refurbished AMAL 376/319 carb for my Indian...ready to install...it's also stamped 9/66,so I'm assuming that means September 1966...allegedly off of a 500 cc BSA Royal Star...Pilot Jet:25,Main Jet:270,Needle Jet:106...I'm eventually going to rebuild my original AMAL 389/16,but I was hoping that I could use this one in the mean time...looks like it will bolt right onto the "Y" shaped manifold...any thoughts?Did I screw the pooch,jumping on this one because it was such a good deal?I've had good luck maintaining/modifying my three Bullets,but this "ground-up" restoration is new to me...any help would be MOST welcome!

If it's ready to install and you got a good deal, what does it hurt to have extra parts laying around?     :)

I myself am restoring a '58 Indian Trailblazer right now and I've learned quite a bit in the last 6 months.  I'm doing a "ground up" restoration too, and though this is my first bike, classic car restorations are nothing new for me.  If you have any questions at all about repainting the bike, I can walk you through step by step what you need to do to achieve professional results.  I've been painting muscle cars for 9 years and I won't steer you wrong.   ;)

I can also help you if you plan on rewiring the bike.  I stripped all my wiring out leaving only the 3 wires coming out from the stator and rewired my bike from scratch using a Sparx battery eliminator a 4BS AGM battery and all new switches and lighting.  Mechanically, there are a LOT of other guys that can give you WAY more info than I can, but there are PDF's for repair manuals readily available for download on the internet that have practically every spec you need.

Good luck with your project.  Restorations are time and money consuming, but they are SOOOOO rewarding and worth it in the end.

Thanks,Scottie...I love what you've done with the Trailblazer...I'm doing the Chief in "Dakota Red",a Dupont 1958 Cadillac color...and yes,I'm going to have to rewire it completely,as the ONLY wiring on this bike is the three wires coming out of the stator!

The original jets for the carb were, 30 pilot, .106 needle, 250 main. ERC

Cool...looks like I can re-jet this one,and it'll work fine...or,I could use this on one of the Bullets,and re-build the one on the Chief...thanks,Roger! I KNEW that you would know!

The largest 376 was 1 1/16" bore and the smallest 389 series was 1 1/8" bore. Royal Enfield used the 376 on the 500 twins and the 389 on the 700 twins in the mid to late 50s time frame. A 376 should work OK but I'd have to check the old manuals to see what jetting they used. It won't quite have the extra edge of the 1 1/8" 389 though.

According to the FINE Mick Walker book,they did use the 376 on some Meteor & Constellation 700's,so it will work,but eventually I will rebuild/restore/replace the 389,maybe with a chrome plated one...
