Hi, can anybody tell me the distance between the mounting hole centres on an F2 caliper where it bolts to the carrier:
Thanks Steve

Sneaked a couple of hours tonight. Pumped some fresh fluid through the rear master cylinder, still amazed it wasn’t seized. Got the new plugs in, coils connected and fitted the exhaust stubs and exhaust. The exhaust fits perfectly and the rest mount lines up exactly with the frame mounting. Just got to fit the carbs and it’s ready to go, but unfortunately it won’t be this weekend as got family stuff to do. [ Guests cannot view attachments ]

Bit more done today, got rear calliper and m/cyl off. Couple of bolts didn’t want to play ball but got them off with no damage. Once I got the seized brake linkage off I found the m/cyl isn’t seized!!

Made some good progress today, got the oil pump off, primed with fresh oil and refitted along with the sump, oil filter and oil tank and filled with oil. Also got the carbs finally assembled ready to go back on.

Got the coils sorted and connected up and lo and behold I HAVE SPARKS :-)

Got some exhaust gaskets coming in the week so just need to get the exhaust fitted, need some carb clamps and then get those fitted and I think I will be ready to give it a kick, hopefully next weekend if time permits.

Yes mudguard could be better, but that’s a way down the road yet

My experiment to soften carb inlet rubbers was a huge success. Using a 3:1 mix of surgical spirit and wintergreen oil for 8 to 10 days turned them from rock hard to very pliable. The carb side softened the quickest being thinner rubber so after about 6 days I reduced the liquid level so only the thicker parts of the rubber were submerged. I will have to see if they harden as the weeks go on. The video shows how soft they are. https://youtu.be/r0GooiUYUAU

Did a bit more yesterday, got the oil tank, filter, sump and hoses cleaned and ready to go back on. Still got to get the pump off and primed with fresh oil.

Also checked out the coils, one has a broken HT lead at the coil end, so swapped a spare one over. The primary circuit is fine about 4.6ohms, but no reading on the secondary. I don't know if I am doing something wrong or if all 4 are duff.

Is there any way to replace the ht leads on Honda CB750 coils. I have a broken lead right as it comes out of the coil.
Thanks Steve

I have owned it since 1982 and ran it until 1990, when a house move liberated some funds and I brought a new vfr750, which meant the CR took a back seat. I have been wanting to sort it for a good few years but time and funds were limited. Kids have moved out now so it was time. It was also the mrs idea to get a big shed to work on it 😃

Well, it was a bit of an impulse buy, I wasn't looking for one but it turned up in my local bike shop Bikewise in leigh on sea and having had a tuned SOHC before, I traded a mint GS1000 Suzuki. For a while I thought what have I done, but it soon grew on me.

I started restoring the CR recently and plan to get it running before stripping it down. Have so far got the electrics working (sparks still to be verified), spare set of carbs sorted, oil drained (no nasties in the oil), oil tank and sump off for clean, cam cover off and top end looks good.
I have not made much progress in the last couple of weeks as I have been playing with diy zinc plating and softening inlet rubbers with wintergreen oil and alcohol (looking good so far). A few pictures from back in the day and how she looks now. I will keep you posted.
