Default Lake Injector info/pics..

saw an old AEE "show" Sportster recently...was restored back to "original back in the day" show specs... was running a polished/anodized single 34mm Lake injector.... havent seen many of these, never on street bikes, vintage drag only.. whats the deal? Do they need a mech. fuel pump? Is the pump cam/crank driven? Streetable? Single/multiple injectors? I think I remember Scorcher running this set-up, I believe on an Evo. Info/ pics appreciated...thanks in advance...

Ran one "back in the day" (1973). Piece of crap, in my estimation. Gravity feed, no fuel pump. Very simple "Let's pour gas thru metered orfice and see what happens!" circuitry. Ran fine on the top end, but idle to mid-range sucked. Prone to leaking and if you left the petcock on accidently, you filled the engine with hi-test. Not good. Here's one on the '66 before I wised up and went to a B.

the Lake,Posa and Star are all very similar and found their way from small aircraft and onto bikes.You can see the disadvantage a float bowl might be on an airplane engine,right? l have a 28mm Posa sitting on a shelf,l bought it because it looks cool.The simplicity of design is beautiful but has serious limitations.They are fantastic for drag racing and forced induction or where space is limited but for a rider they are pretty hard core.Too hard core for you there bunky,try the stock CV Sportster carb with one of those big double scoops on it an a "who`s your daddy " sticker,hehehehehehe

From Custom Chopper Nov. '73 - Jack Burns's 92 inch Panhead.
It's running a set of 35mm Lake Injectors on a rare set of S&S dual carb heads. How Cool is this?

I worked in a shop in Orlando Fl. back in the 70's that sold Lakes for a while and I have to agree with Stan66. They were marginal at best, Great top end, hit or miss every where else. We also sold SU carbs, Del Orto (Weber) Dual Throats, Mukuni and others. At that time everyone was looking for a Performance Carb and grasping at straws. Up untill the second generation of S&S carbs (early S&S had issues.) it was a real crap shoot. Every Carb was Good at something, BUT none were good at everything. But it was a lot of fun!

I've done a 67 Triumph with a set of Lake's on it, after I figered out how to tune them they worked great, just don't forget to turn the gas off.
the secret was needle to slide height for running mixture and then the indexing of the "D" shaped needle for idle mixture.
and a little adjustment goes a long way with those carbs and the label "fuel injectors" was a joke, they are just bowl-less carbs.
