Go Spreetard! Nice work and pics. Will add these to the Wiki topic for Spree intake/reed mods this weekend.

Wait! is the bottom of the manifold matched to the top of the reed cage? if its not then your going to get itake turbulance because the outer edge of the manifold bottom is wider than the inlet for the reed cage.If the reed cage inlet was wider than the bottom of the manifold,thats ok.

[Spreetard]

They are "matched" for the most part. +/- a couple of mm. This here's tinkering, not science. So far, it works well. Mayhaps I'll more carefully engineer the next one. That was the goal, though, to match the ports on the reedblock to the intake. I'm thinking about knife-edging the plastic reed block next, then the case...

Next time it's off I'll check it against a reed block without the reeds, see how close my guesswork really is. I was mostly focused on not grinding through the sides honestly. It's not suitable for jumping, as the intake is not as strong as it once was.

Should i add these pics for wiki to solve questions about my choice of tools?

[ae86guy]

befor i got my sb intake i did the same but i also used the dremal to do the reed cage it self to match it up i also did the block as well

[toboggan]

nice pics of the stick!

That looks really nicely ported!

Greetings:

Dude! I've been looking all over the place for my Stick. I'll be splitting some engine cases soon, so can I have it back?

Your compression gauge is Way nicer than mine, though.

spreetard you shoulda just taken the one i already had done issok if you wanted to do your own i understand

Thanks - tuners take note, many a fine point s are explained by bakaracer.

One thing about the Honda design - they did not match the intake to reed openings. Intake is larger than the reed inlets for both the Spree and SB50. Taking what bakaracer says to heart - starting with a Spree intake, then carving to fit may beat the SB50 intake and save $$.

iff i took my spree intake and ported it what would my tolerence be . how much can i take out.. and to those that used a sb50 intake what metod did you use to compensate for the sprees oiler system

[Spreetard]

On the sb50, the oil line goes into the carburator. With a spree carb on the sb intake, you must either tap a new nipple into the intake or pre-mix your oil and gas.

[spewya]

if i was to run pre mix what would the ratio be .. also would i get rid of the oil pump ad how would i go about attatching a new nipple to the sb50 intake
