Frame not back from platers yet and no prices as yet, all the other nickel and chrome parts are with them as well, I'll let you know £ though.
Almost every nut and bolt is stripped now,
Found someone who has or can supply fork o rings and seal etc, stantions will go off for re Chroming and overhaul even though there not worn where it matters and the ally legs will get polished

The head is going off for new guides and valves complete tomorrow
And the cases are already into the vapour blasters workshop after which I'm sending them up to have new APE studs fitted and a visual check over.
There going to sort out new pistons and rings.
I was advised that the gearbox bearings don't usually wear except one but might change all anyway as I get them trade cost.
I'm away for a couple of weeks, when I come back hopefully some parts will be ready

I already have a CR 750 replica in Honda colours but I want a CR 750 in Dick Mann colours but a usable bike, like with electric start. The other one is a balls out racer and not very usable even though it's road registered.
It's early days but I have a 1977 frame with V5 in good condition, shot blasted in primer and ready for chopping about.
I have started to remove Some brackets
Early days

Also the wife won't see it.
So let's call it the "CR 750 for road use build"
It might be a bit slower than the Rickman as there's a bit more work involved me thinks.
Post by: captaink on August 05, 2015, 05:46:14 PM
The frame and nickel plate may be completed this week, won't hold my breath.
The oil tank and a few bits are at the powder coaters.
The cases are at the vapour cleaners.
The heads gone up to have new valve seats and valves etc.
I'm going on holiday for a week so and when I'm back the parts should all be done.

I can't remember the speed ratings for bearings, do you know offhand Ash
These people talk about C3 and C4 rating.

markB on the sandcastonly site did this excellent table on the early CB750 engine bearings, and many remained the same throughout the models. I played safe, bought an 11k mile gearbox from the States and Genuine Honda output shaft bearings from Yamiya. If you have Excel installed click on the link for MarkB's table

The head has gone off already and it its fairly likely that the top engine case will go off in a few weeks for new studs to be fitted.
As for replacing the Pistons and rings etc for new standard size it may be more beneficial to have the cylinders bored out to 836cc and use a big bore wiseco piston kit.the parts will be easier to obtain and less hassle.
Am I correct in assuming that the big bore kit will not need new rods or uprating anything else and will not require new cylinder sleeves just a rebore ?

Prices.. well often I have a few other bits done but the cases,and five engine covers etc were
£140 inclusive.
A previous batch, head,cylinders rocker covers etc were £100
Try doing that yourself with stripper and parts cleaner.. Is a no brainer.
All done by TSR in Sevenoaks area... His name is Dave ,, pm for phone no.
I might, only might remove some of burrs on the top casting which is purely cosmetic then let them re vapour clean it, this will even the finish again, the cost will be only a few pounds

The frame is back from platers, there are areas that the polishing could not get to but there still plated just not super smooth.
All the bits seen and some that are not are polished nicely though.
All the brackets look really nice in nickel and chrome.
At moment I'm doing one of many pre fits just to make sure it all fits and I have not lost anything.
Engine spacers, I have made in stainless.

Frame was a bit of a pain due to its size but it got there in the end.
Fork stantions have been re chromed and should be back in a day or two, I was unable to get the seals for the betor forks so in the end I had them done by someone else.
Usually I build forks myself.
Once there back the whole front can go back on.
The engine will be the slow bit as I'm in the hands of others.

I have repaired a few small imperfections in the fairing and re shaped the rear section / seat.
There be painted in orange with black wording and stripes and the painter I have used for years will ensure all stripes etc are prepared and lacquered so that you won't feel the lines or edges.
The painter being an ex racer, having raced against agostini in his day knows what I want from them and he unfortunately charges me accordingly , but you only get what you pay for I'm afraid.

The cylinders have been rebored to 836cc ( big bore kit ) and the head has had new valve guides,new springs and the new valves have been ground in.
They also repaired a cracked fin.
The engine casings have gone of and had new ape studs fitted.
Next job will be to have main and rod shells replaced after the crank has been inspected, I'm leaving that to D & M to decide on what's best. No cutting corners so it's got to done 100 percent.
I'm doing some work on my 61 Harley at present so while the engines under way there's no time wasted.

The engine parts are almost complete. " Just got to build it now "
The cylinders are rebored to suit the big bore kit to 836cc
Heads are completely rebuilt with new F2 valves, guides, springs etc
New rod bearingsfitted, new Crankshaft bearings ready to go. New tensioner, cam chain in fact most parts.
Casings have new APE studs fitted and the cam was sent for inspection and found to be in nice condition so just polished.
All the internal parts like primary chains, clutch plates, seals etc are David Silver supplied
Covers polished all shiny !

When I bought it I was told by the seller it was an original S&S tuned bike. It certainly had the S&S exhaust that was very, very, very loud! Reading the MCN road test of the S&S Rickman from the 70's the registration of my bike is the one directly following the S&S test bike, so maybe it did have all the goodies fitted? I couldn't check the rest of the engine for any other signs of tuning apart from having a finned alternator cover and the exhaust but as it cost less than 1.5k I wasn't too bothered, it was a genuine CR Rickman :)
Sadly it has been in bits for at least 10 years following the engine throwing oil from the breather over the rear tyre and bringing a new term to the meaning of 'riding on slicks'. Its going to be my next restoration after the 400/4 is completed.
I do know from stripping the engine though there are no S&S bits in there, certainly not a big bore kit and wild cams so I guess at some point the original engine went bang and was replaced with another standard engine with the original S&S exhaust fitted.
Where did you get your frame re-nickled and can you divulge how much it cost as this is going to be a major expense in the restoration of mine. I have been quoted upwards of 500 pounds for a strip, polish and re-nickel. Most platers I have asked wont even touch it saying either their tank is too small or giving me horror stories of the nickel salts becoming trapped in the frame tubes and rotting the metal from inside out. The other excuse is the bronze brazing of the frame becomes damaged during the stripping process with the brazing going soft and the frame deforms! Now you have your frame back have you noticed anything untoward? My own view is if Rickman nickle plated the frames at least 40 years ago and they haven't fallen apart and massive holes haven't appeared in the frame tubes due to nickle salt corrosion they must be ok to strip and re-nickle?
Lovely bike by the way and I look forward to seeing the finished product 8)

Post by: captaink on March 11, 2016, 07:00:14 PM
The frame was re nickle by Capital Chroming co in the Old Kent Rd. London S.E. But they didn't want to do it, as you say there tanks are not big enough. They sent the frame away to someone else to strip and they did not tell me who.
It was returned to them,they then polished it as best they could but some of the areas are really not very accessible. They then nickel plated it.
The finish is very good overall but not sure if they would do one again, you need to ask.
I had quite a few bits nickel plated such as the swing arm etc. and quite a lot chrome plated as well as all the ally engine parts polished so not sure how much the frame on its own was. The whole lot was around £ 1400 and took about 4 weeks.
Some updated pictures of the engine build although its a little further along from this now.

The Rickman frame is different to the CB750 frame.
I wondered if the engine could be lifted into the frame or like the CB you need to lower the frame over the engine ?
taking it out I lifted the frame of the engine but not sure if putting it back the other way is possible ?
Answers ????

Good news the exhaust arrived yesterday so I could not resist sticking the dummy engine in and trial assembly of the exhaust to get an idea of how it looks.
1st impressions are good, this is a 1978/9 Rickman frame and the exhaust is a 1975 style.
I was informed it would fit and luckily it does even down to the rear support bolt being in alignment.
It needs aligning 100 % but looks more than suitable.
As I'm having the bike painted orange and the tank is backorder, I have still sent the fairing and other parts for painting, as the orange is a flat colour it will easily match up with the tank when it arrives. :D
Post by: captaink on June 14, 2017, 07:14:12 PM
Also by putting the dummy engine in I could make sure the spacers for the engine to frame that the Rickman frame uses are perfect fits.
I made and replaced the steel spacers for polished stainless steel ones.
Post by: captaink on July 24, 2017, 04:39:01 PM
It will go back to the paint shop tomorrow and finished then lacquered.
All this will need to be stripped to the bare to fit the rebuilt engine, which unlike the original frames should lift in with clearance.

The tank finally arrived after 34 week from order, it was worth the wait quality is superb. I had the Monza cap and two 1/4" brass fuel taps. Although one tap is too close to the carbs and will require a slight adjustment.
I have just received the tank strap which will need brackets at either end to fix too, these I'll make in stainless steel, then the tank can go off to the painters.
The exhausts are now complete after a small amount of tweaking as these were not made for this model.
Post by: captaink on December 04, 2017, 04:39:52 PM
Nevertheless getting the engine aligned by modifying the spacers ensures the sprockets are aligned correctly and the chain runs straight.
The Rickmans method of wheel adjustment is not as straight forward as most bikes but once you get your head round it it's fine.
Adjustment is done by offset washers on the frame to swingarm.
The chain runs true now
The fairing is just how I want it, no transfers as everything is airbrushed on and lacquered. Rubber trimmed around the edges.

These I had crimped on after modifying the crimps and ends slightly.
The tank welding is second to none , the tank came from Holt works, Tony and Michelle Holt.
As I am now using a 4 into 4 exhaust instead of the 4 into 1 it came with, the gear and brake pedals are in the way so it is currently being modified.
