And that is why your equipment will always be substandard with substandard performance. Of course you believe you know better. :jack: To stupid to learn from your own mistakes much less the mistakes of others. Oh and somebody needs to break your ball, as little as they are. :roll:[/quote]

Damm! you're right. I forgot you had just finished riding and driving all of my "equipment" over here at the ranch, so you know that it all runs like crap. Got me again. Really though, it's sad what has become of this post. If I believed I knew better, like you say, I would not have posted. Thanks to the members who added some positive feedback, i'll try your suggestions and report back. Tolerance level for dumbass? Why is that even nessesary? I was asking a question, looking for feedback, not insults. That is not in any way positive for the forum. You get some young kid on here who knows nothing about what he's doing, and looks for help he gets screamed at. Away he goes, his tail between his legs, not getting the input he needed to get his "equipment" running right. Before you go lashing out at people, think about the fact that everyone might not be as versed as you in 2 stroke tuning, and are looking to the forum for help, not to be told they have little balls, a dumbass, or that there scoot will never run right. I am finished ranting. Go scream O'Doyle rules somewhere else, where I don't have to hear it.


THAT being said, to the others who where reading, I have the uni filter, but had read on the forum that the stock spree airbox/intake was a tuned system and the scoot would run better with it in place. That's where holes come in. I guess I overshot that idea. Needle is in the middle clip position, 85 jet. I have the 90 jet, i'll give it a shot. I am just not a fan of the way the uni rubs on the shock, wearing itself out. Thanks again.

Greetings:

Well-typed, Deuce. A very well-reasoned response to a harsh critic. We like The Bear in small doses, but I also called him on his belligerence.

The UNI filter has the potential to maximize air-processing at WOT, but it's the part where you need to get up to high revs and speed that makes it so hard to tune on a stock Spree carb. A bigger Main and full-rich needle position can help. The shock-friction thing could be addressed with UNI's 15-degree angled version, UP4112-AST. (You can peel off the red overwrap in the privacy of your Boudoir.)

However the cast-in fixed Pilot Jet issue doesn't easily go away. If you had a spare carb and Indexing Drills in sizes down to Fractions of a Pubic Hair, you might consider attempting to enlarge that Pilot by some percentage, hence gaining optimal mixture for idling and most importantly, Coast-Down. Off-throttle is where many Big-Bore Kits go to die. The engine continues to generate Pumping heat, the fan spins slower, the oil supply diminishes and the tiny Pilot fuel stream does little to keep things cool.

See if you can find a post by USPMale, our AbsentSpree carb expert, and send him a PM. Maybe the Pilot-drilling thing has been done?

I'm going to take things one step at a time, reporting back. That should best suit the situation. I installed the 90 jet, changed nothing else today. Spree runs about the same, a little more power on the hills if anything, but I do see a change for the better. Wondering what to try next, cover some of the too big holes I apparently drilled in the airbox in error? I'll mix up some of the 100 to 1 fuel that the wheelman suggested. The mixture screw is 2 to 2 1/2 turns out, with no difference either way(that I can tell riding it) Any input would be great. Thanks

Greetings:

Covering the holes might make that new 90 Main feel a bit big. It depends on the size of the holes in the airbox; If they are small enough to generate negative pressure when the RPMs climb and open throttle, the carb sucks harder on the fuel metering openings - especially the main jet.

The air bleed's effect is subtle, but has some effect everywhere in the RPM/jetting scheme. If it needs to be that many turns out, the main may be too rich. Adding a little oil will tend to make it a bit leaner, so maybe a good thing? Read the plug and go from there.

It was 1.5 turns out before with the 85, but ran the same 2 turns out also. I'll try covering 1 hole at a time, just to see what happens. Thanks

I never got my 44mm bbk to run right with the stock air box still attached.

The rubber tube that connects the air box to the carb creates a bottleneck .

Ditch the air box, run the uni and use the #90 jet :imo:

Try to find a sb50 (elite e) reeds, intake, shock, and exhaust too. :wink:
