Peter Horton refurbished the original clocks including converting the rev counter to a suitable 400/4 item from the 250 rev counter that was on the bike. They look fantastic and I asked Peter to put the MPH/KPH face on the speedo for no other reason than I like them :-).This morning I collected the finished paint set from Tony at Cyclesprays in Horsham, Sussex. He has done a marvelous job considering the tank I took to him! He placed the decals on the tank (decals supplied by Piki (Reddice) on here) and clear coated them with the same on the side panels. I'll decide it I want to put the saving lives sticker above the fuel tank, I don't really like the look of it!I went to refit the carbs yesterday but thought I'd bench test them first with fuel to check the floats, of course one leaked really badly (No 1). A frustrating three hours spent adjusting the float and re-testing got me nowhere and it looks like I'll have to fit one of the new Keyster float valves to replace the original as the tip looks worn. What is it about 400/4 carbs, they work fine one minute and flood the next!Next job will be to fit the carbs and handlebars with the switches.
My only observation about 400 carbs is anecdotal if the flooding is not when the bike has been running normally.lf the bowls have little or no fuel in them you can get a situation where as the float bowls drop down down at an acute angle they rest against the bowl side causing a potential sticking incident. This enables a situation where sometimes there is a jam of the valve in the 'gap' between the float bracket brassware and the valve seat as it is out of the normal operating range/angle of seating due to the low fuel level in the bowl. The above jam is such that even thought the petrol is pouring into the bowl the float is unable to rise as it should as the valve is stuck in the above 'gap'.This does not happen as an event every time my fuel is switched on after being stood for a few days or drained over winter. I have just rocked the bike from side to side whist astride my 400 this causes the flooding to stop pretty much immediately after any petrol in the overflow pipe has run out.I suspect it is linked to the brassware attached to the float and possibly previous attempts to adjust the float level.
