The seat alteration was genius!  ;)

Thanks   but I  did about 35  years ago ......trouble was I couldn't remember how had bolted all the bits together. I've over engineered the rubber mounts to much and need to simplify them (at later date or just leave it  ::).

 

Northy:
Ok mudguard arrived  from  D&M engineering and I made a quick a fork brace from stainless plate , as lot cheaper than the £112  for cb400n fork brace on the net . It shouldn't really need it as i've double disc but it will give bit more rigidity to the front end . Also provides more secure location for the brake line clips  ;D

So thats my front end done , but no strips/decals yet as still not decided on what they should look like but should be pretty easy to do.


So I slapped a spare tank on it for road test and its safe to say this is a horrible colour combination

The fairing still looks too big for the bike and may be changed at later date , the bike sits very high . I took it for a spin around the block to "test" it ,to find that :-

1) Clutch adjustment way out  (now sorted - has new plates/springs so will need to bed in)
2) Running too rich. Gets to 3.5 k and splutters (later removed some very sooty plugs, so standard jets going back in from 98)
3) Number 1  carb leaking the all new o ring had split , may have caught it when fitting, last spare fitted.
4) Oil leak from rocker box around no 1 area. In other tests the bike was on it centre stand, the leak occurred when run on it side stand . So looks like need to remove the rocker box off to see whats happen in there , at least there's oil up there.
5) Brakes need to bed in 
6) Steering and ride feel fine.

So tank to  still to do , need fuel tap but suspect the yellow tank may be donating one.

Side panels  to  add but need some  Cb400 four  logos or something .....going back to 80  I used letraset letters and number , might get some vinyl ones this time  :)

So nearly there but not , really disappointed in the rocker box leak it was "glued" into position with a casing compound.
