Hi Martin what are you doing with your top yoke .if your running clip ons.

[martin_uk]

As I want to keep options open to be able to change back, I will leave standard mounts, may fit a short section of 7/8 tube.

I know many Cafe Racer style fans will disagree, but I am aiming not to make any changes that cant be undone

Started the frame fit up and found the swinging arm caps would not stay in place, struggled for 20 mins so put to one side.

Went back to it later and was able to fit with a bit of jigling

Test fit of clip ons and dummy tank found that steering stops need modifying to stop bars hitting tank.

Trouble is the stops on lower yoke are quite narrow and drilling will weaken.

With forks in place tried mudguard fit  the one supplied and painted is too narrow School boy error not to check before painting!

Now starting to doubt plan, maybe better to do as modified F1 with standard bars and front mudguard?

[martin_uk]

Decided to modify steering stops.

To save having to remove lower yoke, it can be done in situ.

Needed extra long drill to drill from front (need longer drill to allow chuck to clear yoke) and then drill M4 tapping size 3.3mm from rear.

Used M4 Allen screws and seems to do the trick

Steering lock didnt want to come out.

I havepreviously  used a M6 bolt held in place with stiff wire inside frame tube and tyre lever.

Didnt have a key and you have to turn a little to left to align.

It came out a bit, but no further.

Decided to drill.

Small chisel to try turning to left.

Manage to lever out and could see why it was a struggle.

Fitted instruments, but F1 bracket studs get in way. Luckily I have a spare K8 one to try

Thanks Pete, still not sure about clip ons, as they were uncomfotable 30 years ago

Not planning any long journeys.

I do like the look and can afford to play around, with two completed CB750's

Removing seals in forks was tricky.

Tried a slide hammer with lipped plate behind seal to pull out. but ended up drilling and fitting screw and using claw on crow bar to lever out.  Be careful not to catch fork leg with drill.

Unfortunately front mudguard is 100mm wide at fixings (was described as 120mm) and I need about 135mm.

Anyone found a suitable mudguard or have a suggection on filling the gap?

[yozzer74]

Very nice  but looks expensive 

[yozzer74]

No it want that bad 75 pound I bought a mud guard from cafe racer .ended up in dust bin . Was no were near the size it should have been .

[martin_uk]

Checking main bearing clearance with Plastigauge.

Thought I would do as a precaution.

Crank shaft fitted to upper case which is on a  Workmate bench opened to accomodate studs .

Plastigauge applied to all main bearings and held in place with grease.

Fitted lower case and torqued main bearing bolts.

Remove bolts and case.

Looks to be about 2 thou on all, which is within tolerance.
