Can anyone tell me what the P that is stamped on the bottom of the head means?

Not getting really anything done on bike. Been busy with backyard project but hope to be done soon. I did receive my Amals back from Lund, very nice! Hope this irons out the idle and acceleration issues I had before.

Dunno what it means. My 74 has the same P on its RH10. I would guess it may be a casting mold designation?

Lund's is highly recommended if you want to stay original. They've done a few sets for me over the years (first ones were in 1999)

Movement on slide feels really good and slick. Excited to get done so I can actually have carbs I can tune!!

Just got my parts back from the powdercoaters a few days ago. Used the template to blank it off from Old Britts, hoping I hit all the correct spots on it!! Have cleaned and painted blanking areas and waxed. WIll probably do another wax to make sure have a good one on it. Had frame coated Semi Gloss black, the guys who did it gave me a good deal. Was $150 to blast and PC, I went back to blank it to save the money and a lot of headaches!! Hope to make at least monthly progress on this but having



Dang, thats a good price on powder coating, I got a quote for my CB500 frame, $500+, Its calif, dont even think about chroming, some places send the parts to Mexico.

My frame and bits sat for about a month before they got to them. I was not in any hurry but they felt bad it took them so long and gave me a great deal. I also went in after they blasted and taped everything off. I gave them the instructions from Old Britts but they offered to let me come do it. Saved about $40 per hour for them to do it!!
Fortunately / Unfortunately it is somewhat of an Indian Summer here in Mississippi and I have been outside finishing up after having a pool put in. Now I have to get into attic and finish up insulation before the cold does hit! Never a dull moment!

I did get my Isos in and going to have friend cut down front piece for Mk III dimensions. Maybe once the cold sets in I can get back to the bike!

You should have bought the new ones that do not require cutting the front mount!

I purchased the ones from Old Britts. Didn't see any that used the MKIIa mounts.
