Honda Spree and Elite 50 Forums

I NEED MORE HELP.
I JUST GOT ANOTHER 87 SPREE AND THIS DOES NOT HAVE AN AIR CLEANER OR HALF THE AIR BOX FOR THAT MATTER.IS THERE ANY WAY I CAN USE A VALVE COVER BREATHER OFF AN OLD CHEVY FOR AN AIR FILTER? OR WILL THIS AFFECT ITS RUNNING CONDITION TOO? THANKZ!

Dude, turn your caps lock off. No need to shout.

I've been wanting to try the Chevy breather thing. You have two Sprees? Try it on the one that runs and see how it works. If it does, use it on the other. The critical thing on the intake is the length of the rubber tube to the carb. Do you have that part? If not you could probably make something up with coolant hose.

Let us know what you find out, and how it impacts idle, wide open throttle, and part throttle response.

Or you could buy a filter box/rear fender on Ebay.

Just buy what parts are missing from drichardson@core.com or from eBay. When you complete it, it will run. You're going to spend a fortune to see that 'rigging' just won't work.

I have done the same thing, only with a tiny performance air breather from Auto Zone, and it didn't work worth S.... It got way too much air.

Mikuni style carb REQUIRES slight vacuum to pull the fuel UP from the bowl. All the parts are cheap enough (used) so why bother with 'rigging' it?

never mind. i finally got all the parts.

I plan on trying the chevy breather idea as well. has anyone else tried it? if i get it, i will get the size 70 jet to compensate for the extra air, should that setup work?

Simple answer - NO it won't.

I have a mini K&N cone filter on my spree. I use a size 70 main jet. It's been running like this for 4 years now. top speed of 65km/h. I've also done some other mods though.

what other mods did u do?

gutted my exhust, modefied the front pully, port and pollished intake. run on 94 octain fuel. or aviation fuel when i can get it. i'm looking into moding a polini race pipe to fit. other than that, i weigh 200 lbs. and it helps to give her a push from a complete stop to get her going. but hey, i keep up with traffic!

When you say "gutted the exhaust," did you saw apart the muffler and remove all the baffles, or did you drill it out?

I took a 1/4" drill bit about 1' long & drilled 4 holes in the back. in a box pattern. I didn't just drill stright through though. i took a lot out. i didn't have a welder at my disposal at the time so i couldn't cut it open so i just took as much out as i could with the bit.

OK. That's the speed mod listed in the tech section. I'm buying a spare muffler to try this on; should be here next week.

I was contemplating sawing it apart and removing the baffles, and enlarging the rear outlet to 13mm (from 11.) Drilling would be easier though...
