Bought one new in 1978! Almost as good a wheelie bike as my 1985 Honda XR350! I've found another one of these and hope to have it in my garage soon!

Awesome RM400

Awesome!

👍👍

Thanks for sharing this video. I have a '78 SP370. Owned it for 30 years and I am exploring different carbs for it. I am running the original carb with a Vape ignition. It runs great when it wants to. The carb is just too dang finicky and will kick back when hot, just unpredictable..uhh. Cleaned and replaced just about every piece in it. My question is what kind of throttle are you using with your TM carb?.dang those things are expensive..but it sure seems to rip! Thanks!

Love it! I have a DR370 project as well. In the early stages. Great information, Thanks!

I had a 1986 sp200 new. Uncle had one of these we picked up in the back yard of Kanawha river.. Arround 87. Had to lap the valves and clean the carburetor. The rear wheel had bearing and hub issues at we kinda fixed. No rear muffler so really loud! Hit the kill swich while riding and open the throttle. Then ON with the ignition and an earth shattering "Kaboom" Had to Show Local boy CHris Martin how to ride at Campbells Creek in high school on his KDX200 air head. Ended up taking both bikes up near the "Nose" at Witcher Creek. Good times and would love to ride with Chris again

Sounds strong!

The best fun bike fun times if only we could go back absolutely beautifull and reliable the 1970s were interesting motocross bikes so simple to work on we enjoyed very much these twin shocker air cooled bikes

The way this bike looks and sounds and how your started it. and let warm up gently are the true signs of Zen motorcycle care and rider, Tip if you will...Do empty the carb after riding it by closing the fuel valve and let it Idle or jus lean it to the ground., also have you change the Spark plug recently and cleaned the air filter? Thank you for sharing. Myself former MX racer from the 70's.

These machines are beasts. I still have mine. I put it up 35 years ago.I would just barely skim the ground on it in 3rd gear.

And rider🎉

I thought I recognized this bike ❤

Old school thumper 👍

They really need a water truck.

Nice looking RM 400 and thanks for taking us along for the winter ride ! 👍 That's something a lot of people overlook is short rides in cold weather as it's just different . Frozen ground and cold air make sound carry farther . I wonder if a shot of starting fluid would help on those cold mornings ?

The greatest machine made in 1979 it the RM 400 !

Had one...last ride was a concussion, dis located knee and a broken collar bone. Very sneaky power

Nice work putting this together. Very cool race action too!

This fucking song was from Motocross Madness on Playstation 1 💀💀

Good thing the rain stayed away for most of it

I lost my silencer on the second lap on jump 10

Hey Bud, you made your SP400 12 volt video private, could you send me a link? I appreciate it! That video was helpful.

Beautiful man I own a 78 rm400 and a 78 yz400 that I’m rebuilding and man did that freakin rm rip. 80cc to a 400cc what a jump (ridden other big bikes but not mine )
