Has Anyone Tried Dave Silver Float Valves?

(1/3) > >>

Lynx:
I see 16011-329-004P is half the price of a genuine Honda float valve kit but I remember the 400 Rebuild site on BTInternet saying avoid pattern carb parts as they are more trouble than they are worth. I know these fit most SOHC models but I had to still the question somewhere.

As the genuine kits are SO expensive, I am very tempted by these. Do they work well? I'm suffering a bit of leakage at the moment :-\.

I get that sometimes.... it's an age thing. ;D

The float valves that Keyster do are not very good we find.... I polished up the old ones eventually and they are 99% ok with no fuel puddles , maybe the odd drip.

I'd like to know if these DSS ones are better... the pins look a bit thicker to me?
The tip and seat are what matters I imagine ... accurately machined and the right material.

I used pattern parts on my 500 and always had a slight overflow every so often, seems to be a common problem.

Lobo:
I've used Keyster carb overhaul kits on my both my 750K2 & 400F carbs. The K2 overflowed terribly prior to the rebuild unless used regularly.... and is now 100% good all of the time. The 400F carbs now overflow regularly at Tap On, but with any vibration seal immediately - ie I take it outdoors to turn on the fuel / start it. A mixed bag with Keyster then, but I do feel if used often there'd be no issues whatsoever. As mentioned, OEM must be the way to go... but with 8 carbs & those prices....!!!

OddJob, you're possibly right with 'old carbs' ... but then a big gamble with used parts; those old carbs you're buying might be Keyster! I've had too many times now I've got stuff from a parts dealer only to be bloody let down @ their condition, repackage them, send 'em back (at my expense). A waste of my time, and realisation that some folks idea of 'good condition' is nothing like mine... I now prefer the less hassle pattern / OEM route where financially acceptable... acknowledging tho' that it invariably costs more in dosh, but less in grief.

Horses for courses I guess...

mickwinf:
cost is a factor, but the original ones leaked anyway. I too don't remember leaks back in the 70s so try to use genuine parts where possible
