I have 4 NOS sets of carb needle kits which I bought in error to be used evidently with the German etc. exhausts. Wonder why they had a variation in exhaust types for these markets. Do you know Chris?

Cheers... AshD

Please can you give me the number engraved on the needle

Thank you

Marcello
congratulation for your sandcast
nice job

i'm surprised regarding the helmet holder bracket  on your frame
normaly on a sandcast you should not have this bracket

Do you know why do you have it?

maybe the rear frame has been changed???

Thank to let me know what do you think

Yes,I can't find tread in soch4 forum or in HONDAMAN book.Something about harmonic noise or vibration in hi rpm.

This has been discussed many times at SOHC.net and is a pet of mine. I have reviewed many pictures of virgin lower ends and there is NO consistency from the factory as to whether the chains should be synched or staggered. Many people have stated that they should be one way or another, but there is no verifiable back up to either position. I am open to anything scientific one has to say.

I received this as a PM from HondaMan: "I'll make a post of this when I can get my picture, later, but...I just disassembled a virgin 750K7 engine and found painted-on timing 'marks' on the primary chains, and they align the plate-to-plate setup we were kicking around earlier. So, it looks like Honda aligned them instead of staggering them, when new." With his permission. "We were kicking around earlier" refers to the conversation he and I had on the subject.[/color]

 This is not conclusive as I have seen at l[/color][/color]east 2 virgin bottom ends where the chains were staggered. This leads me to believe Honda didn't care.  The chains in my current project are synched. FWIW.

Good imformation Ron, for what its worth i have lined up the green dots on the chain, this makes it link to link


Ok so here are pictures of the gauges back together, there is still more work to be done, i will put new shrink tubing on the wiring, as it is getting a bit hard , also i wont seal up the bottom with silicon until the clocks are up and running on the bike, other than that here they are for know, all the hard work done











The rear chrome plates are ok but not perfect, thing is that the replacement ones from Honda are not the same as the originals, so its either keep as is , rechrome or replace with modern alternative


Here are the originals



here is an original left, next to the new style  right
