Side covers - are the same as the US and CAN RD400F, just different decals.
Tool Kit - a correct OEM tool kit will be hard to find and very expensive. If you just want a similar universal kit you can get one from Economy Cycle (who sponsors this site) https://www.economycycle.com/product-category/tools-hardware/tool-kits/  Yambits in the UK also sells tool kits. https://yambits.co.uk/tool_kits_parts_for_yamaha_rd400g.html
Kick start Lever - reproduction levers are available from several sources. https://yambits.co.uk/rd400g-kickstart-lever-p-37969.html  The same part was used on the US & CAN RD400F. There's a used on on eBay right now: https://www.ebay.com/itm/176355883141

Here's what yours looked like when new.

There was one for sale here locally a few years ago. Kind of unusual to see a Canadian bike for sale in Southern California.

:'( Bummer Tim, not good news. On the positive side, now you have a chance to rebuild it better like you always do.

Welcome :cheers: and congrats on the new bike. Post up some photos!
The 400G is a Canadian spec bike, and is basically the same as the Canadian F model (only the graphics are different if I recall correctly). It should not have a points ignition because the RD400F/G in Canada came from the factory with CDI.
Sorry, I can't help you with a service manual as that model is one of the few I don't have.

3J7- is correct for an F or G mode1. Both were painted New Pearl White, but graphics differ between the years.
F model frame/engine numbers start with 3J7-000101, and G models begin at 3J7-020101
Cylinder head is 1-piece and a 3J7 part
Carburetors and cylinders are 2R9 parts
Wheels and brake calipers are 2V0 parts

Quote from: 2 Smoker on April 28, 2024, 11:53:56 AMThat is so cool, I personally have not seen a two stroke on the streets in a long while :thumbs:
I was a little bizarre, not only because you don't see 2-strokes around much, but because I was sitting on a '75 RD125 and taking a pic of another '75 RD125. :hifive:

The only person I've ever heard mention it is Rich (racerclam on this forum)

General Chatter / Sighted in Seal Beach - RD125
April 27, 2024, 10:52:18 PM
I was out on a 30-mile ride on the RD125 today and rode by this parked in downtown Seal Beach. It was a little bizarre, sitting on a RD125 and taking a photo of another RD125.  :jaw:  You certainly don't see many of these around so I thought it must belong to a guy I know who said he traded for one recently that was given to a friend as part of an estate sale. I messaged him and sure enough he said it's his. It only has about 2500 miles, but wasn't running when he got it. He just got it running again.

It doesn't look so hot now but I'm guessing that it will be immaculate sometime soon. He has a RD200B with chromed Higgspeed chambers that is amazing. As for the front wheel looking so much better than the rest of the bike...he said when he got it, it had the wrong front rim on it, so he built a new one with re-zinced spokes.

Quote from: 85RZwade on April 27, 2024, 04:18:58 PMI think I used the connectors from the lighting kit correctly
If you refer to the Mark Haase edition of the instructions you did that step correctly. :affirmation:

Quote from: Hemi on April 25, 2024, 01:48:52 PMMy original '77 back in the day was a D model.
In Canada, the E's arrived the tail end of '77.

Correct, 77 model year is a D and 78 model year is an E.
In North America each model year is manufactured in the end of the previous year, usually between August and about November or December. So, the RD400C models were manufactured at the end of 1975, RD400Ds were made at the end of 1976, and so on. And a'78 model for example would be made between about August and November of 1977.
The US model RD400F 2V0 was manufactured a little later than normal (November 78 through January 79), likely due to the EPA certification and regulatory items that model had to go through, but I'm not 100% sure why the build dates for the US Daytona are later than other models.

To my knowledge all North American '78 models were Crystal Silver.

Quote from: SoCal250 on April 06, 2024, 03:54:57 PMYamaha is now reportedly pursuing adding a satellite team, something they desperately need to keep pace with other brands. There's just not enough data collected and shared with only 2 bikes on the grid.
Latest rumor is that Pramac is considering a switch to Yamaha. VR46 has already turned down Yamaha.

Quote from: m in sc on April 24, 2024, 04:19:00 PMspare set of cyls back from the shop being bored to freshen up the top end .. one on it has a slight tick that might be? piston slap. 38.5mm bore of fury.

I had a hell of a time finding a shop that could go under 40mm.
More POWAH! :olaf:

Micro Muscle: Under 100cc's / Annual 2-stroke ride
April 22, 2024, 07:18:00 PM
Today I made it out for my annual Earth Day 2-stroke ride. Met a friend for breakfast in Newport Beach and then rode through Huntington Beach and Seal Beach. It was a little cool and foggy with some drizzle.

Stop for breakfast in Newport Harbor.

The little 50cc performed flawlessly on the 42 mile ride.
