Ah, the old two cycle, smoke and rattle, miss those.
Very well done! RD 400 with twin expansion chambers.
Good to see one of those preserved for future discussion.

Do you have a GoPro? Please do a vid of this bike.
I remember pulling the front wheel up was just a twist away.
God I want one again now.
What gives the RD350 I had had 63hp and I just looked I thought the RD400 was more but not.
The RD500 is 88hp, weird.

Thank you for considering us for your motorcycling needs.We ran my dyno for the first time in 4 years. On a customer's St II ported street RD350 with our RZ350 reed package and 30mm carbs, it made 56HP (rear wheel) with SPEC II F1 chambers!
and thats a modded out 350
i think the 350 was 32 , the 400 35 but more torque

It was rated 63hp, look it up RD 350F, I did not make it up.
It was 52hp rated, just found the specs on the exact bike, 63 was euro model.
Doesn't answer the RD 400hp though, why less than the RD 350?

Don't try to fool the old, we were there.

yup look at that spec cooling liquid . that puts it a rz 350 , was a diff animal with power valves , the rds were air cooled . the banshee was based of the rz eng , 350 liquid . the rds are like harleys you can only get so much out of a air cooled eng the rd400 was defunk after 79
Yamaha Rz350 - Wikipedia, the free encyclopedia
there prices are very old , but this is who i delt with
Spec II -- RD350/400 Performance Products
or comparing a 76 yami 600 to a 87 yami 600 is not the same
my old drz400 made more power than a xr400

Agree, water cooling did help hp a lot.
Kenny Roberts that is a blast from the past.
Thanks for bringing up some old wonderful memories, ah the memories.
Just makes me laugh when I see people pulling the front wheel up, I think, did that before you were born.
Watched some YT vids of the Rx Yamaha, that sound is mesmerizing.
Darn it now you got me looking.

ah yes the wail of it doing a wheelie at 40 is cool some would say just at 40mph . it is a air cooled 400 . even if i have a aarp card , we may grow old but i dont have to grow up :zombie: even the wife liked the wheelie with her on it . hence the. i back rest aka as the wife keeper
if it was not there it would not go over welloh lala a 400 i bet shes a lil pistol!!!
AAAHHH the old RZ 350.. I still miss mine. You Americans have to remember though that the U.S.A. spec RZ 350 was down on power compared to the Canadian/European spec bikes because the U.S.A. bikes had converters in the exhaust pipes to make them "cleaner". All I know that with Boysen reeds, and rejetting to #180 main jets,using synthetic 2 stroke oil my RZ used to pull to 10500 RPM's in 6th gear with stock gearing. (red line was 10,000 RPM's) The magazines used to call them R Zingers. BTW Stuna,, I am jealous as hell of your 400,,,, I do remember the RD 400 Daytona Special..those were really nice.
