poor acceleration

me again. i was just out on the spree and i have been noticing poor acceleration. i tried the pulley mod but it diddnt help any. the carb+filter are clean. any ideas?

oops, never mind. i looked under the spree and the kickstand is bent. it was jamming into the tire. the spree accelerates so hard now because of the pulley mod. i was wontering how my friends kicked my * off the line and now i know why i guess.

The pulley mod or the intake mod made it faster? Or both?

If you want to be really hardcore, I'm still waiting for someone to drill out their exhaust per the "spree hopups" document. That would actually require a larger jet and some plug chops.

the intake made it faster. but i reversed the pulley mod because it gave it better acceleration but i lost top end. (i added a washer to make the belt fall lower rather then taking materia away).in other words, the intake was a sucess!

Post Pics on ur site and how did the mod work for you and not me? that mod causes less belt tension, therefor losing any acceleretion and topspeed.

how did you do it. you need a small washer and you take the starter pulley off the engine and you put the washer inbetween the silver pulley and the brownish one.

He reversed the pulley mod, which means he added back removed material.

I knew that restriction looked bad, had no idea how bad.

That's what I did, but it caused the BELT to lose tension, and therefore allow more slack in the belt to slip more, I would think shaving down the outer half of the pulley and popping it on would cause the belt to be tighter and make it have more torque (higher acceleration rate but lower top speed). I don't get the whole washer mod/idea at all, it doesn't make any sense.

wait how do u do the intake mod?

removing material will cause the belt to rise up and cause a more direct drive=poor acceleration.you just file the restriction out of the intake. go to freewebs.com/spreepics and look under performence.

You have just inspired me to go pull the intake off my parts Spree and file it out. It's so nice to have a parts Spree, that way I can switch back to stock parts if I don't like how a mod works.

I'll let you guys know how it goes and maybe get some pics. (maybe)

Well I did it, and I must say overall I am pleased! Very good little modification there. Had to play with the mixture a little bit to get it back up to speed and still need to fiddle with it a little bit but overall it works good.

It tops out at 32 MPH now versus 28 before and also gets going that fast quicker, but it seems to have lost some "grunt" going up steeper hills for some reason and drops down to 24-25 MPH. May try going up on the jet a little.

I used a corse hand file to file out the metal and then smoothed it over with a sanding drum in the dremel tool. It basically looks identical to the one on that site.
