Ruckus - EVI (Rolling Wrench) vs NCY CDI Box

[503ruck]

Hello. Grateful to be here. I don't do social media and finding quality forums is hard these days. 

I own a 2015 Honda Ruckus. 

Current need to know setup is: 

Pollini Variator w/ 5.5g Dr. Pulley Sliders 
Gates Belt 
NCY Driveface 
Airbox Delete w/5" length hose cut at 45 degree for intake (TRS Kit)
Yoshi Exhaust  
Scooter Swap Shop Performance Carb for Honda Ruckus with Slow Jet (33?? came with and seems to do ok...) and Main Jet at 80. 
Just installed NCY CDI today and been testing things out a bit. 
Trailtech Vapor (currently set to PPR 2). 

Looking to get higher top end and performance overall which seems to me I should go with the EVI (discovered it existed a couple days too late lol). However, what's the bang for the buck as it's quite a bit more than the CDI I currently have installed. 

I'm 200-205lbs. Live in Pacific Northwest. Altitude is around 200'

Today I got it up to 40-45 with relative ease on flats. 
Small hills going up, I was able to go between 30-35.  
Downhill spots I got to 48.5, but it wasn't THAT big of a hill and I think I could have easily hit 50+ should I have kept going (Although I've never been a fan of measuring how fast a bike can go by it's downhill speed).

Tach is not consistently reading things right now. It was set to PPR 1 prior to installing the CDI. I was getting accurate reads then and hitting rev limiter. When I installed CDI, Tach would read RPM's north of 12k+ almost as soon as i took off. I changed the PPR to 2 (cut's RPM reading in half on my tach) and it seems to be reading it accurate up to about 8500 RPM. Then when I hit 43..44..45 the tach drops to like 5k RPM but my engine is still running full steam ahead. Then it's bouncing around. 

Anyway, looking for feedback on the EVI vs NCY CDI and any suggestions on my Tach readings. I'll mess around with my loops to see if that's causing an issues as well. 

Cheers!

No experience with Rolling Wrench, but the rest of your setup seems solid.

The questions are -
How many miles on your belt? They can take a few hundred to break in.
Have you tried going up a jet size?
Have you tried any other roller weights?
Have you done the sharpie test to make sure you’re using all of your variator?

You might think about dropping $35 on a stand alone tach to get this sorted out.

Not sure about miles on belt. Put it on mid summer last year and rode it daily/weekly. It's pretty well broken in.

I was running 85MJ for a while but felt that my top end wasn't "kicking in" so I went down to an 80MJ and can definitely lift off, so to say, when I start getting into the high 30's.

Yeah, I've messed with the weights. I got 3, 4.5, 5, 5.5, and 6.5 weight sets. Have run different combos. Tonight I tried 5.25g and I liked the 5.5g better but wanna give the 5.25g another test run before I change back.
Ironically the 5.5g seemed to get me up hills better than the 5.25g but I figured it was due to bike not being warmed up yet.

I have not done the sharpie test but my Variator shows about 1/8" - 1/4" of room at the top. Been flirting with getting MET gears to help with that. I should start doing the sharpie test as I just always forget.

You think a standalone tach will provide a more accurate read-out than the trail-tech vapor? If so, I'm all in. Kinda wanna get one anyway and switch to that and my phone for riding. The Vapor is kinda bulky.

Appreciate the feedback.

Have you tried this setup without the CDI?

[503ruck]

I've tried a variety of combinations without the CDI.

I ordered the EVI CDI from Rolling Wrench.
Also picked up a new PC20 carb from Ebay.
I'm going to remove the installed NCY CDI, install the new carb, tune, ride, tune, ride, cry, tune, ride, repeat. Then install the EVI CDI. Hopefully by September. lol.
I'll keep ya posted.

Best to make only one change at a time. That way you know what’s effecting what.

But either way, do post results!

Thanks for the comments fellas.

Installed the new carb today. Ordered a PC20 from JC Racing Online via E-bay. They have a website and seem to be legit. jcracingonline.com/20mm-Big-Carb-Kit-for-Ruckus-Metropolitan-JC20.htm


Carb install was easy. Had to re-route throttle cable so I got to tear into the bike a bit. I swear that part is just as fun if not more fun than actually riding it. Did some trial and error for several hours and here is where we are...

I landed on 5.0g Dr. Pulley sliders. I like the extra zip I get as most of my riding is in town. However, I still have enough top end to get 40+ without much effort (no tucking, fairly quickly). I was able to hit 35+ on most hills with one incline allowing me to climb to 40+. Max speed was 52.9 but on the bottom of a hill. Engine didn't seem like it was screaming although I was cause it was the first time I'd hit 50 and it's been a year long goal, but 50 on a Ruckus, is scary shit at first... lol...

MJ is 85 and seems to be working as intended. Right at the 30mph mark, without fail, engine gains a considerable boost which propels it up fairly consistently from there.

SJ is 40 and that's where I'm having problems. I'm confused on what's happening.
I started with 38 and then went to 40.
Having same issue but 40 seems to be more accurate as air/fuel screw was dead on at 3 full turns (6 1/2 turns). Only had minor tweaks from there to get it having a smooth idle.

However, when I go to give it a kick "burrrrp" or even just slam it wide open from the jump, it'll most of the time sputter and then die. I can ride all over and be fine. I just don't take off so fast.

To me that would be a lean issue yeah? That's why I went from 38 to 40. But I'm thinking tomorrow I might try and put a 35 in there and see what happens.

Any feedback will be much appreciated. I'll keep posting. It's nice to have a place to ask questions.

Update -

Been testing MJ all day today. Ran 6 tests - See the picture attached.
Question - I don't have any higher jets but it looks like there wasn't much change in overall top speed and average speed from 92 to 95. So I'm wondering if 90-95 is going to be my MJ. I say 90 because while that was top speed listed, I also ran a different route that has a bigger downhill on it. So that kinda skews my numbers a bit for that one and I need to run it again. Today was windy as heck too with gusts up to 20mph so that factors in as well.

So, based on these numbers for MJ - should I continue going up into the 100, 105 range ?

I'm also thinking of going to the 6.0gram sliders once I get my MJ dialed in. I can consistently get into the low 40's with 90-95MJ and 5.5gram sliders. However, I feel my top speed isn't quite getting there. Up hills I can maintain no less than 35mph so I don't want to compromise that by going up in weights.

The tinkering continues. Appreciate the input.
