CBX1000 Cafe Racer – engine build

Posted on 16th March, by John_Pellew in Cafe Racers, Current Builds. No Comments

For those interested in the CBX1000 Cafe Racer Project, I now have an almost complete 2nd engine, which will be a hybrid of the Pro-link casings, crank & rods, Z head, barrels & pistons and pro-link gearbox internals & clutch, this will I have been advised give the best of both worlds, ie the HP of the early Z motors with the stronger clutch and drive of the later pro-link motor.

I have also been investigating that options re big bore kits etc, with a minimum of 1150cc , this in-conjunction with Z heads, some mild porting should put the engine in the region of 115hp.  If you wanted some serious muscle then kits out to 1425cc are possible, with power in the region of 160bhp and a suitable price tag to match.

The completed bike will have a target weight of … Read More »

A couple of preview pictures of the finished carbon seat unit and the part completed paint scheme / layout.

At the time of writing the seat has been sent to the Upholsterer and should be completed on Monday

When finished this bike will be for sale – serious inquiries email john@taimoshancycleworks.com

 

 

 


Latest up date on Carbon Bonneville

Posted on 16th March, by John_Pellew in Cafe Racers, Project Bikes. No Comments

Below you can see the progress being made on the Carbon Bonneville bike, in place now is the rising rate rear linkage of a design so far found to be unique to Taimoshan Cycle Works and the tank has been modified and is taking shape ready to have carbon moulds taken.  Also you can start to see the start of the seat/trial section styling and construction.

In later post, you will see the Bonneville T140 ES  electric start unit that was acquired of ebay and is currently being refurbished and the “new” old stock lucas starter from a Norton Commando that will have the front housing replaced by a custom machined housing to mate it will the electric start unit.

Carbon Swingarm construction for Carbon Bonneville – step 9&10

Posted on 11th August, by John_Admin in Cafe Racers, Project Bikes. No Comments

Step 9 – Machining of needle roller thrust bearing housing for swingarm pivot

In this section I will show that final machined product of the bearing housings that will be bonded into the ends of the pivot section of the carbon swingarm.  Each bearing housings contains a combination needle roller & ball bearing thrust bearing with inner sleave. This design will provide a low friction pivot joint.

here you can see the finished items with the bearings inserted ready for polishing then bonding into the swingarm.

 

 

 

 

Step 10 – Machining of the rear spindle carriers

 

These parts started off as 65mm dia FMA aluminium bar and were first machined on the lathe to the correct diameters and profiles and then set up on the milling machine and hand milled with a lot of care and patience into the final part which was … Read More »


Carbon Fibre Swingarm construction for Carbon Bonneville – Step 7

Posted on 11th August, by John_Admin in Cafe Racers, Project Bikes. No Comments

Step 7: wrap carbon reinforcement of the whole section

In this post you can see part of the process of competing the Delta pivot mounts and further wrapping of the swingarm.

You will also see that I needed to provide clearance at the centre point of the swingarm as the swingarm would have fouled on the main frame at the expremities of the pivot range.  The clearance was provided by cutting out a section of the reinforced tube and then bonding in anouther piece of carbon tube that I had made earlier for this purpose.

 

 

 

 

Next post will include details of the machining of  swingarm pivot bearing housings and the rear spindle carriers that will be bonded into the ends of the main spas

 

 

 


Carbon Fibre Swingarm Construction for Carbon Bonneville – Step 5 & 6

Posted on 2nd August, by John_Admin in Cafe Racers, Project Bikes. No Comments

step 5: main spar bracing core wrapping

The step involve adding another 2  more layers of plain weave carbon cloth over the whole foam core brace area. Again there are a few tricks to this process which I don’t care to to share but you can get the idea.

I will say that it is really important in these stages to take a lot of care in cutting the carbon cloth.  To do this I first make card or paper pattern/templates of all of the pieces that I need to lay. I cut and test fit all pieces, taking a lot of care not to fray the cloth which is really fragile at this point.  neatness is everything at this point and mistake can be hugely costly in both materials and time.  I there is about £400-500 quid of materials and about … Read More »


Carbon Fibre Swingarm Construction for Carbon Bonneville – Step 4

Posted on 2nd August, by John_Admin in Cafe Racers, Project Bikes. No Comments

step 4: main spar bracing core

After wrapping the main spar joints, I need to brace the main spar in the section infront of the wheel leading up to the pivot tube.

The reason for this bracing are 3 fold.

1) to add to the lateral  rigidity of the main spars like a gussett. This hugely reduces the point loading on the wrapped and bonded main spar joints by spreading the load.

2) to add tortional rigidity to the structure. This is achieve with the specific laying up of different types of carbon fibre in the brace core and on the outside of the area. Layer the fibres at 45/45 deg to the  direction across the flat area of the top and bottom of the brace will increase tortional rigidity of the structure.

3) to provide a platform onto which the suspension linkage mounts will … Read More »
