Headlight needed for 72 R5C #11
General consensus is don't use the jets supplied with aftermarket carb kits. Gaskets and seals should be ok though.

Most original jets still available from Yamaha.

Headlight needed for 72 R5C #12
Still trying to find a headlight but I’ve been working on other things and ordering bike stuff.
Coils, wires,points,condensers etc.
I was able to borrow a cool Yamaha dial caliper with adapter to do my timing.

I have not found my box of R5 stuff with the headlights... I think I know where it has to be at my other place. I'll look tomorrow when I visit.

Very annoying when I know I have something and I can't find it... seems to happen a lot more often lately. :Ugh

Your old-timers syndrome is at stage 1.
I'm at stage 2 where I am finding things I didn't know I had.
Stage 3 is when you go looking for something, forget what it was, and then start doing something else.

Yes i'm at the stage of finding it after i've gone & bought another one. It's a guaranteed finding method.

Okay... I just remembered I had another box for my R5/RD400 project in a closet here... and there it was! I found the light itself but not the Honda box with the part number. One thing that's nice is it takes a standard H4 bulb.

Searching Partzilla I found what I think is the Honda part number 33120-MF5-751. When I bought mine several years ago it was still available from Honda for about $60 plus shipping. www.partzilla.com/product/honda/33120-MF...a07313893a9d04c2be86

I found that number on ebay and seller includes the bulb and rubber cover which is nice! Ebay one has the same "HM-34" number on the back as mine and looks the same. (The full number on mine is "HM-34M-S". Ebay number is washed out by flash)

It's not a perfect fit for the Yamaha but brackets are close enough that it can be made to fit. I think it's the "adjustment" bracket on the side that's shorter on the Honda... Take a look and compare to yours...

I'd also ask the ebay seller if they would measure for you to make sure it's the right 6 3/8" size or whatever oddball size they used. I have an old original Yamaha one and the Honda one I can take pics and measurements of it would help you.

Here's the link to the one on ebay. Sounds expensive but it's has a common and cheap replaceable bulb so should last a lifetime vs. the original sealed beams that are trash when they burn out.



P.S. R5 and RD350 use the same headlight.

I have a LOT of "spare parts" I've acquired by that method!
