[1976 Yamaha RD400C]

Sort of crazy money for a not-stock 400. (Repainted in the wrong shade of red.) I mean it's clean but holy smokes!

Pretty cool stats:
-- For the first time since 2006, an American rider leads the standings in a grand prix class of the MotoGP world championship.
-- 3 podiums in a row, the first rider to do that in any GP class since Nicky Hayden in 2006.
-- And coincidentally, Roberts currently has 69 points.

Looking forward to what he can do at Le Mans!

This Holden LX Torana SS rolled in late. Right hand drive and it sounded pretty mean. I dig it.

That Holden body shape looks to be derived from a Vega. I always wanted a Cosworth Vega back in the day but it would have been a never-ending series of engine failures from what I remember reading at the time. IIRC it had Aluminum block that turned out to be better in theory than application for production cars?

A friend of mine had a Cosworth Vega in high school. Pretty rare car for a 17-year-old to be ripping around So Cal in.

I've heard that road paving has been going on at the Dragon and daily closures are to be expected for almost a month. Hopefully the group will be able to work around this. And new pavement will be nice and smooth but greasy for a while

Ken, your videos had me all fired up to get one of those cool Yamahauler neon signs from Modern Artifacts for my garage


...until I found out they go for $1200.

I met the owner of this '35 truck when I was out on my neighborhood walk about a year ago and he was working on it in his driveway. It's a Factory Five kit that he built in his garage. He decided to paint it the same color as his E46 M3 because he likes the color so much.

This really nice restored MT250 parked right behind me.

I finally made it out to the Donut Derelicts weekly Saturday meet in Huntington Beach. I don't normally go because it's so early in the morning. They start rolling in a little after 5:00am to get parking spots and it's over by 8:00am.

I didn't really decide to commit to going until late on Friday night, so I went bed around 12:30am and was up at 5:00. Ugh. Did a quick wipe down on the trusty old 125 and took off for the show. I was there to grab a parking spot at 5:45.

Parked right in front with the other bikes and then went inside to get some delicious donuts and a big coffee. (I really needed the coffee!)




I was parked next to this nice Guzzi


A group of 5 guys rode into together on Whizzers.


And I ran into my friend Bill with the RD125 that I had spotted last weekend in Seal Beach.

Interesting. Looks like someone has made some changes to it over the years.
The tank and front fender appear to be from a RD400F.
The front end looks like it's from a '76-77 model. (You can measure to be sure but those look like 34mm forks, not the 35mm used on the F/G models).
The front wheel is from a '76-77 model and the rear wheel looks like it's from a '78 model.
The brake rotors are '76-78 versions.
The front and rear brake calipers are pre-79. And the one on the rear looks like it was a front one at one point in time based on the badge clocking.
The swingarm is also not from a F or G model, but a '76-78 RD400.
The kickstart lever is from a '76-78 model.
The round Yamaha badge on the left engine cover is not from a RD400 but a RD250/RD350.

Kazakhstan GP postponed until later in the year due to flooding in the country.

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 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
