Honda Spree and Elite 50 Forums

hey wheelman, i was reading your flash III build and before you big bored it you ran it with the 9:1 gears and said that the gears gave it something to do. you said your top speed was something a hair under 50. how did it cope with hills compared to pre-gear change? i read it like the only time you noticed the taller gear was from 0-5mph.
thanks! oh and annother question, i bought a new gear case gasket, what do i use to grease it to be able to remove it easily after i install gears? (as i plan to later go big bore and will go for 8.4:1.)

Greetings:

I dunno, hills are scarce in Deepinnaharta. I do know that if you lighten up the rollers, it [puts the 9:1s well within reach. It did 48-49 as a 50cc and bone-stock power. 90/90 rear Pirelli though. I never did stopwatch testing, but there's little doubt that it took a little longer to get up to speed. However the only really noticeable downside was 0-5.

When I swapped my 9s for 8.4s, the gasket stayed in one piece. I had used Harley-Davidson special purpose grease for my gaskets because that's what I have handy. Any high-temp grease - such as wheel-bearing grease - should be fine. Just don't use stuff designed for ball-joints and other such non-heat applications. Slather on a generous coat to both sides before assembly.

No the spring will get softer as is breaks in and heats up.

ok thanks bakaracer, that makes more sense!

Update: I ordered 9:1 gears/clutch grabbers/roller pack from scootspecs, excited for them to get here.

question. i am running 7g rollers right now and its a bit revy, but i can climb hills like mad. when i get my gears in will i want to go even lighter on rollers or try the 7s at first and see where that goes? what rollers are people using on their 50cc elites with 9:1 gears. thanks!

I'd keep the 7s. They may be perfect. You want it a bit revvy with taller gears. IIRC I was using 7 or 6.9s early on with my 9:1s. Bone-stock power was good for nearly 49 MPH. The Esteemed Burnt_Toast says his Corsa bore gets to 60 with 9:1 gears, and I believe him.

thanks wheelman. right now with the 7 gs im seeing almost 45 on gps! cant wait to get my gears, should breach 50 i think assuming i dont warp into the 1950s on my first speed run...

and at 5300 miles on my scooter im guessing my stock bore is getting tired. this summer it will get a BBK.

let the gears begin! in anticipation for my gears that should arrive today, i got my scooter torn apart mostly last night. i was haulin * at the drive side and had everything dissmantled when i realized i hadnt taken off the rear wheel or my exhaust... so i re assembled the final drive, got my exhaust off, then attempted to take off the rear wheel... no such luck, i obviously need an impact wrench. im taking it to work today to zip the wheel off, and tommrrow i will take it to press the new gear on! some pics included.

what brand gears do you have? I know the asa brand gears don't fit right without removing the plastic washer off the middle gear set and have to replace it with a metal one.the plastic one is to thick so it binds up the gear when you replace the cover.

I had the same issue with 2 different brands of secondaries. The countershafts are the same overall length, but split differently in terms of bearing/gear surfaces.
Thin metal washer fixed it for me too. I happened to have a spare that fit. If you don't it's not a hardware-store item. You could try sanding down the plastic one between two blocks of sandpaper until it fit.

yeah i just finished sanding the plastic washer down. for some reason none of the shops are open today andi dont think ill be able to have my gear pressed on. ill have to wait till i go to school tommrrow to do that.
but as for the plastic washer it is as thin or a little thinner than the metal washer on the oposite end of the shaft.
thanks! oh and is there a thread anywhere that helps with clutch grab springs? i figure use a brake drum tool and wear saftey glasses...

oh and i got rumia gears from scootspecs.

Greetings:

Weird. My plastic washer was considerably thicker than the metal one on the other end of my '01's countershaft. I had a leftover from another scooter that took up the slack perfectly. I didn't plastigauge the clearance or anything, but I did comparison-mic the shafts and predicted the metal washer would be close to perfect. With the plastic one, the countershaft was jammed by the cover bolt tension.

Wheelman: what i meant when i said my plastic washer is as thin as the metal one i was talking about after i sanded it down. initially it was twice as thick as the metal washer. took some time and a little skin, but it worked! haha

just got my 2k clutch grabbers on. my parts form scootspecs got here today, i ordered them on thursday, so thats pretty fast. just waiting for tomorrow to press my gear on... got all my parts ready for install
