The newest one was today on Nicks '76 RD400 build, not a total bare frame build but a nice daily rider Stg 1 less big carbs (stock carbs w/primary needle jet conversion and uni pods) still on points but have more upgrades planned soon.

My shop is in a business industrial park and next door to other shops and their compressors fire up in my video's and because I'm a 1/4 from the airpark airplanes fly over too! 
Enjoy the RD life no matter what! 

In this fire-up I have 1 gallon of 93 pump gas on 40:1 premix. I did prime the pump by removing the bleed screw and made sure it was bled to the pump with no air bubbles after about a minute. I did pull the pump cable up to full pump for about 45 seconds.
I check it tomorrow by putting on a rubber nipple on one carb at a time and verifiy the pump is working as it should after the rebuild,
re-shim and cable timing. Timing is set to 1.9mm. I'll post up the jetting results after some dialing in here at sea level in Clearwater, Fl.

Here's mine after I seized it and put a new top end (yes, from Chuck) on her. I should've let it warm up more, but you know, I had to ride it.

In the Ytube vid G had lost one so he took off the other one waiting for another to be made and shipped.

Put some tuning and some miles on Nick's RD400 this week as it rained every day most of the day last week.
I modified the Fast from the past rearsets, they are nice but they suck at shifting as most aftermarket one made, other than Joe Spooner custom handmade ones.
I machined a thick piece of aluminum on the mill and welded it on making the shift arm longer by drilling 2 new holes further from the pivot to see what would work the best as the footpeg lever had 2 holes to adjust with, and was gray anodized so didn't want to weld on it.



When I have more time I will start a build thread of the bike...
Nick picked it up and took it home yesterday! It's a gas to ride this rowdy '76 RD400 STG 1  (almost... bigger 30mm carbs and ignition is needed some day to complete as a full stg 1)

Out for a late night jetting run on US HWY 19 and a stop at Johnny's for some pizza!







Wheelie Time!!
