ok it was bizz day fist good day this year so worked on the yard most of the day..
did put put the stock pipe on and put the 7 gram rollers in the max rpm went down to 6660.. the stock pipe did have more tork at low rpm top speed was 40 but 35 to 40 took for ever..... so the slippage is down but so are the rpms..... did not have time to try the other rollers ( 5 or 6 ) next good days will be this week end so looking for some input form you guys ..

Let the beatings begin... LOL just kidding. What is the stock roller weight supposed to be, I'm just curious. I've just started playing with my variator on my aero so I've been watching this thread.

Both my unmolested Aeros, one '87 and one '86, had 10 gram white roller weights when I cracked open the grease cover.

[paulpauly7]

same here the se50 i have also had white 10g rollers in it and didnt look like it had ever been open

[bakaracer]

you are running .40 thick reeds so that will restrict flow some. stock is closer to .25-.30 thick carbon reeds on how it flexes. 87 elite 50 came with 10g rollers.

as of now im running the stock read a 3 petle reads .. going to oder some 0.3 mm read stock in may ..
by the looks of the chart that is set up with a 90/90/10 tire stock variator the 3.5 tire and ruckus variator is about the same as a 9.19 fine drive ..

Greetings:

As Bakaracer suggested, .4 is pretty thick, thus stiff. If that stiffness resists bending in the airflow - which is the only reason the reeds leave the plate, they choke the effective intake port area and so limit RPM. Just a thought.

im running my stock 3 petle reads as of now ....
still wood like to no what i can do to raise my (6660 ) rpm and speed..
this weekend is going to be good weather so im planing to try a fue things but one at a time ..
check the compression ( book said 114 -171 ) put on the mill head and try the home made pipe??? because ive have never try it with the heaver rollers ... i may even try my one petle read with the 0.4 mm stock on it .. becase none of these tack long to do ....

Greetings:

Does the tach go to 6600 whenever you open the throttle wide? Or is that a max RPM at top speed?
Either the engine is lacking power altogether, or something else is preventing it from getting to its optimal RPM.
Intake restricted somehow - a gummed-up air filter - or carbon-caked exhaust?
A very weak Contra spring in the driven pulley can do that too, along with too-heavy rollers.
Even a stock Spree should want to rev higher than 6600. Something's not right.
