Honda Spree and Elite 50 Forums

Greetings:

Very nice work. Hey run the tranny vent into one of the holes of your custom filter cover. Self-oiling element!

A floor mat would make that bike look sick. I love the black look an AF16 brings to a spree instead of the silver/gray engine color. Looks so good on red Spree's.

So I took her for another run today (a bit cooler outside) and was topping out around 32-33mph. After going down a hill the engine choked out so I am thinking either too much fuel or too much air. I plug some holes on the cover and it bogged very early and wouldn't get up to speed. I opened the fuel jet a 1/8 turn at a time (starting from 1.5 turns) and still didn't stop the downhill choke. I ended up taking the air filter cover off and bam pulls great up to speed (35mph) and doesn't choke going downhill. I heard you will seize the engine with just a pod filter but it seems to run the strongest.

-Should I add more holes to the filter cover? Till is doesn’t bog downhill?

-Up jet the carb so it doesn’t seize the engine?

I plan on buying a new plug and running with the pod filter to see the condition. I have a nice smoke trail behind me. I just feel like the engine wants too much air.

That motor WILL do 40 all day with the right filter hole combo. Try less holes. More isnt always better with these babies.

I have, just double checked to make sure I installed the #80 jet and confirmed it. I guess I am going to add more holes till she is runs the best and buy a new plug to insure the air/fuel mixture is ideal.

This was the last time out for the year.

Running good?

Running Great!

Sweet....now toss a Corsa/Arrow/Naraku/Stage6 on there and do 65!

I am going to start with a Polini Variator and 15x42 gears, they should be here next week.

15x42 is an interesting choice. Good thing with those is you’ll probably not need a ZX trans. They wont give you blinding top speeds but they also wont kill acceleration like taller gears would. Keep the updates coming!

I do not believe the 15*42 secondaries (10:1) will improve enough to be worth all the trouble. Try the 16*42 set (9:1) and increase the strength of the springs in the clutch for a better take-off. Here's the gear ratio chart http://hondaspree.net/wiki/index.php5/T ... ion_Ratios
I have run both of those gears in my stock af16's and I ended up giving away the 10:1's and put on 9:1's. Just my opinion....yomv
I like the polini vari
Just be sure you have made clearance in the case, and get some shims so you can use the stock boss instead of the one that comes with it. You may find that it is too long to use with the stock belt. 7-7.5 gm rollers is about right but it will depend on the clutch springs you use.
Awesome build and thank you for the easy to view pics!

I was able to catch my order in time to swap the 15*42 with 16*42 gears thanks to the scooter swap guys! Do you think a yellow 30% spring would be a good starting point?

I Just know that the 9:1's are best if matched up with a 1K torque spring and 2-3K for the shoes to grab. But it can vary depending on the brand. I assume you are referring to the Malossi 30% yellow spring? That one seems to me to be tricky because I don't really understand exactly what "30%" means. I have one and actually didn't like how it worked with a corsa bbk w/8:1 gear setup. I assumed that it's color corresponded with all the Taiwan 1500rpm yellow springs but seemed like it was maybe a 1200rpm spring instead of a 1500rpm. I did not test it against a 1000rpm Taiwan spring.
SSS has some imported spring sets (Italian?) and it may be your best bet to get a few extra sizes so you can dial it in to your liking. I don't know what that is. I just want to give you some of my experience to see if it helps you. I have acquired a couple extra stock clutches and set them up with different springs to easily test out what works best for a particular setup. Welcome to tuning

Yes, Malossi Yellow is a good all-around spring. I tried Polini White and Blue and they were too soft. It wouldnt downshift on deceleration into the corners unless I lightened the rollers way too much.

The 30% refers to the compression strength of the spring being 30% stiffer than stock. The Polini White and Blue (i think) are 15% and 20% but dont quote me. The Malossi Red being stiffer yet at 35%.

I dont quite understand the rating system of Contra Springs with an RPM number. If one is rated at 1500 then what happens AT 1500?? Upshift? Downshift? These shift points can be changed with roller weights. Someone enlighten me.
