Keihin Cvk34 Carb Parts Manual I Set
1 carb has a spit every know and again and the vacuum dropped at the same time. Without the workshop manual I set the mixture screws to 1 1/2 turns, put the mercury gauges on and got the sync to within 1.5 cm after setting the revs to 2K but whilst doing this I noticed that No. Just setup the carbs on the Zeph. However I was having problems gettung it to idle consistently. I replaced the pilot screw and the main jet with brand new ones.These guidelines should be followed when installing carburetors and other Keihin products:4 Pack of Float Valves to Suit Honda CBR900 Fireblade Keihin VP carburetor. Pack of 4 replacement float valves to suit the Honda CBR900 Keihin 'VP' carburetor.
I've read that this may be a lean setting so I've unscrewed 3 off them out a further 1/2 turn. I've ran it with one plug out and it didn't spit and the spark was very blue and constant. I may be remembering wrongly but the first one I had pulled from 30mph in top very smoothly. It seemed 'chuggy' until you get to 3K on the road. Took the plugs out and cleaned them, also swapped them around but with 8 plugs I wouldn't expect a problem.
Keihin Cvk34 Carb Parts Full Flow Fuel
After a period of time has elapsed you can see visually if any are passing at the float needle valve if the level in the tube increases.Similarly if you (under the same conditions above) run the tube down into a container, after an initial surge of ten seconds of full flow fuel, you can assess the recharge rate for each float and float valve arrangement. Confusing.If you can find the correct fuel level setting it is best to do it on the bike with the engine running in the manner you have done statically with the clear tube on the drain outlet.Whilst there if you leave the tube attached and fuel tap open and engine off. It looks like you have a serious fuel leak problem to fix before the spitting habit gets fixed in any event.What is odd though is that with the fuel level appearing to be potentially too high, the fuel level available to the pilot circuits should be excessive and you should be getting an overly rich condition and not a potentially lean one. Reading another thread the level on another bike was at the gasket face and the owner seemed happy with this concept but that may not be factory either. Cant say for CVK from Keihin but 5mm above looks like asking for trouble but it may be the case. This is with a warm engine.If they were CV's as in Mikuni BS34 the fuel level is 3mm + - 1mm below the gasket face of the body from memory.
When wet they as standard, swell up and are a git to get back in. The CV's and RS's have a flat 'fork' and screw to hold them in place.The RS float bowl gaskets are similar, i guess, to the CVK's, being moulded firemans hose (licorice for people of a certain age ). Interesting that the valve seats dont appear to have any means of retaining them. In youre case, two genuine ones, in theory, guarantees to fix the two leaky carbs, whereas four repro's, could lead to four weepy ones!!Assuming the cause is not the 'O' rings round the float valve seats of course. Relevant because some cabrs have a limiting stop at the bottom of the bowl and it is possible to adjust the floats to be almost trapped between the two limits and end up with diminished dynamic re-fill even though the static fuel level may appear to be spot on.General consensus is pilot air screws at 2 turns or a touch more from fully seated but again it would seem dependent on the market they were sold into and the prevailing environmental legislation in force in that country / continent.Dont know about ears on the float needle.Not familiar with Webike or the quality standard of their parts but i think that my experiences of aftermarket (even guaranteed) parts leaves me with the impression that where genuine is available that would be my preference.
Clean again with clean water and blow out again. I am told that you can stitch them in with superglue but dont fancy the idea myself.With an identical set of issues with the CV's I blew out backwards with compressed air, sprayed carb clean, WD40 and anything else i could find, and ultimately ultra-sonic cleaned about six times with the bodies orientated to favour particles and dirt tracking backwards from the narrowest part of the drilling (its exit point in the venturi) to the atmospheric mouth in each case. They do return to nearer normal size as they dry out though.
No amount of plug chops will give you anything like as much info for as little effort. It tells you everything you need to know and in real time. Standard is something like 1 and 1/4 turns open and i think they were all around 2 turns out with a range of 1 and 3/4 to 2 and 1/8 ish and it ran absolutely perfect from that day on.You will only be able to do this with a colour tune. Did that make all the pilot fuel screws the same or as per standard? No. Checked continuity of flow with the WD40 again and again with compressed air.
Unlike old ceramic plugs they are very porous at the centre insulator and are designed to be replaced at lengthy intervals in modern lean burn engines.Noticed yesterday that you can buy an adaptor to take the standard 14mm colour tune down to either 12mm or even 10mm. If you have had flooding carbs or have cleaned youre modern spark plugs with a shot blaster or wire brush they are likely fizzed.
