Honda-SOHC

Having just gone through all 5 pages I love this build.  As someone just starting out on their Cr750 journey it's brilliant to be able to draw on all the photos, research, pointers and tips from you lot (as well as drool over the bikes coming together).  I'm a million miles away from finishing mine but really great to see how other people are going about their builds.

Keith - very envious of your work space, it looks spotless.  I've just had a damn good sort out of my garage here (mainly so I can hunt down parts for my build) but most of the time it looks like a bomb's gone off!

I just thought it odd that it was in there and no mention of it on the microfiche itself. I originally wanted to get it to do the clean and polish as well but the bugger is well and truly stuck 

The piston in the K1 lower looks like a later models piston though, that shouldn't be in there should it?

I've been trying to make some headway with the carbs I have here.  As I have some rebuild kits on order for them at present I needed to get the old needles out of the floats, however looking inside them there was a world of hurt waiting for me with the tiny pan screws that hold the rod mechanism in place.

Now separate to this I'd heard about JIS head screwdrivers and their advantages over Philips heads with old Japanese bikes and having rounded a few of the pan screws in the past I thought I'd have a blast at grinding down a standard Philips to see if it made any difference in getting the screws out.

Wow, is all I can say.  30 seconds on the grinder to take the tip off and angle the 4 edges a little and all 8 screws came out without any drama at all, even the two that were caked in rust or something equally as nasty.  I'm probably preaching to the converted on here as many of you have no doubt already done this but having cursed (a lot) when I've rounded screws in the past this felt like a nice easy win

I want to get the carbs rebuild if possible and then turn my attention to the frame that is currently dangling from the garage ceiling.  I'd like to bolt up some of the rear end and get the forks on, more to see the stance of the bike than anything else as I've only ever seen it in boxes and getting something that resembles a bike, even in these early build stages, will hopefully put a smile on my face and spur me on.

Pretty sure I have that tucked away in one of my many boxes but mental note made

Brilliant, looks like I potentially have a K1 swingarm to marry up to the K1 frame.

Thanks for the intel guys, really appreciate it

The bike is a K0/K1 hybrid but the carbs could be from any year as the basket case I bought was just a pile of parts more than anything else.  Going by the schematics on the CMSL website they look to be from either a KO/K1 or possibly later K2 model (checked the K3 images and they look pretty similar - I have no idea on what the differences are across these years).

As for carb number, do you mean out of the bank of four, if so then is was carb 2 and 3 that seemed to have play
