Glass pack mufflers sound weird on a Datsun. A regular old "turbo" muffler has a more correct for Datsun sound.

 

Unless you have dual Solex then they might sound OK.with a weber DGV I would stick with a turbo style muffler.

I have a Dynomax Super turbo with the deflectors inside But in the morning its still loud untill it warms up. But it has lasted 20years and still solid

As I get older I like quiet. I would put a Walker quiet Turbo on there just upsize the pipe to 1.75 or 2 inch on my 521

Agree on the 'quiet'. I like the push back in the seat more than the display of noise for others. I found a never used $5 yard sale muffler that is larger than my old stock one. Used pipe 'expander' to go from 1 3/4 to 2" inlet. Outlet has 45 degree down bend, no tail pipe. Has a noticeable rumble but probably quieter than the Dynomax.

Todays project was replacing the gas pedal. The original build included a gas pedal that was meant for floor mounting but it was mounted on the fire wall. This meant that the pedal was actually tilted towards the driver and was completely uncomfortable. I first tried modifying this set-up but to get the proper slope away from the driver I only ended up with about 30% of throttle travel. I had a top speed of 42 mph LOL

I ended up buying a really nice Lokar unit from Speedway that is infinitely adjustable as the pivot shaft has fine splines that allow you to choose any angle you need. I was able to reuse the stock hole in the firewall for the cable routing. Need to figure out a pedal stop inside tomorrow.

Check out the gas welding on the old pedal mount. Old school stuff...........

Why would someone replace the throttle pedal on a 620? Was it purely for looks?

 

Hey man, it was CUSTOM!! 😆 😎

Ever since I saw the Datsun ad below, I have been fixated on showing my 620 with a period correct Japanese motorcycle in the back. With the connections I have, I thought that I would easily find one to borrow, but all leads went stale. Due to this not working out, I had my upholstery guy order material for the tonneau cover, which was scheduled to be fabricated and installed tomorrow. Low and behold, an exact copy of a bike I owned as a kid popped up on Craigs List last night and I went and bought it this morning. It's a 1973 Yamaha 175. It hasn't run in decades but for my intended purpose, once I clean it up some it will be perfect. So instead of a tonneau cover, my upholstery guy is recovering a motorcycle seat for me tomorrow. I have a whopping 72-hrs to get the bike all cleaned up. Gotta love deadlines! LOL

So cool! Fits like a glove. Do you have a long bed? 

The 620 is a short-bed and the bike barely fits straight. Thought I was going to have to let some air out of the tires to get the tail gate to close. 🙂

Just got home from a fun weekend in Solvang. Got to hang out with friends, that we sadly don't get to see often enough. There were 5 Datsun trucks in attendance. 1-320 (I think), 2- 520's and 2-620's. It was cool to see the same year totally stock green 620 next to mine and compare the differences. The owner did a great job of restoring it.

Here are a few pics from the weekend. On the way home one of my friends texted me an Instagram post he had seen of our trailer on the way home LOL

As a side note, right before we were leaving to head to Solvang, one of our neighbors brought by his new to him C7 Z06. My wife dd's a C6 so she took it for a spin with the owner in the car. The car has the carbon ceramic brake package and she said that she about threw both of them through the windshield the first time she hit the brakes. Guess what she wants for her birthday now. Thanks neighbor! LOL

Oh yea, BTW, the bike in the back was a big draw and promoted lots of fun discussions. Good addition!

Nice to meet you.

I gotta look into that enclosed trailer thing. Mrs. Rizzo does not like the long drives in the 620. Good excuse...but she heard it form someone else! (thanks)

 

Pictures do not do this truck justice.

See you at JCCS

I had them polished by a professional. You dismount the tires, and he puts the rims on what looks like a tire mounting machine that has an overhead buffing wheel on it. The cost was $60 per rim. One of the few things that actually seemed cheap on this refreshment LOL

You are doing great work here. Love the bike for obvious reasons 😄

 

 

There are currently inexpensive seat covers on ebay. Not sure how long they will be around, they aren't always on there.

Did not suck. There is Michelin star restaurant in Solvang  called First and Oak... so we did that...

LOL We went to the Big Bopper for dinner. I'm not sure if it's Michelin star rated 🙂
