lighter inner pulley

or if ur tool deprived u can hold the outer pulley with a pair of vise-grips.

You should be pulling off the engine fan cover and fan to do this, which allows you to hold the crankshaft still with a socket and wrench. You can remove the front pulley with an impact gun, but you can't torque it to spec with one.

I have an 84 and an 86. The 84 has fins and the 86 looks like the 87 in the pictures.

Hi all, I swapped the lighter 84 pulley on my 86-engined 84 Spree. Slight increase in acceleration, Zero increase in top speed. The increase in acceleration is bareley noticeable; it makes the bike feel a little peppier, that's all. Not worth going out to look for an 84 drive face, but if you have one kicking around like I did, what the heck? put it on. Hope this helps!

thats what i thought would happen. less work on the engine. i dont know why they changed this for 86+87.

well, heavier flywheels for trucks help for hillclimbing, as the revs don't drop as fast. A heavy flywheel is like a battery that stores kinetic energy, it takes a lot of energy to accelerate it hence the slow acceleration, but it stores that energy and helps maintain engine torque when a sudden load is experienced. That's why rock climbers often get heavier than stock flywheels put into their 4x4s, as high rev power and acceleration (as needed in road going sports cars) is not neccesary, but not bogging out your engine while climbing over rocks is. Perhaps Honda put the heaver flywheel in so our scooters wouldn't bog so easy on hills...

I still think they were just being cheap and running the same crankshaft for both variator (Elite SA) and non-variator (Spree, Elite SB?) models.

someone said there spree bogged on hills. mine accelerates up a hill. not sure what year they had tho. mine is an 87.

Yours accelerates up the hills? What do you top out at on hills? What mods have you done aside from the Intake?

no other mods. 30 up hills 30 on flat. no difference.

so you're talking about the crank pulley?

i know on some hondas, they're made with a harmonic dampener to dampen the vibrations coming off the crankshaft as to minimize the wear on the bearings.

Spree's don't need a harmonic damper; the belt takes care of impacts, and the crank is counterbalanced.

No kiddin' mine bogs to 25 on slight hills and hits 28-31 on flat, because where I live there aren't really any true flats. They are always slight grades in one directon or the other.

However, if I hit more than a 35% grade I am lucky to make it up.

How much do you weigh?
