Louis's Genuine RoughHouse50 upgrades

[Weldangrind]

I would think that an exposed variator would only run cooler. If you have a round slide carb, you might be able to move the clip on the needle. Perhaps even with a CV slide. That might help improve the mid-range stumble.

this is the carb that is on mine, WITHOUT the adjustable oil mix screw.

I been adding just a wee bit (about 2 oz. / gal. ) of 2 stroke oil directly into my fuel tank since changing over to the 68cc big(er) bore motor. Still not blowing blue smoke (a good thing) but puffing just a bit off idle (still a good thing) Extra oil, I am guessing, is a good thing up to the point it starts to noticeably smoke. I don't know what the factory correct mix ratio is, but in 275 miles, I have yet to refill the factory oil tank and there is still 1/4 to 1/3 a tank of oil in the oil tank. Seems to me that both my old Honda Express50 and my Yamaha Razz used about 1 tank of oil to every 2 tanks of gas, IIRC. I am quite certain EPA has something to do with that. Our old Husqvarna 268 saw ran 32:1, the new 460 Rancher says run 50:1mix. Why? EPA. That's why. So I borrowed the mechanics carb adjusting tool ( special dealer only funky looking splined shaft nut-driver ) and tuned the 576 to run on the old 32:1 mix. Smokes a bit when cold, but once warmed up it is a cutting little fool! With no adverse effects on spark plug life that I can tell. ----sorry, I know that went wayyyyyyy off topic there -----

Just some facts I learned about who Genuine Scooter Company is.
Remember when I said I though they had something to do with Vespa?

PGO if your curious: (that explains the PGO head stamp on the motor! :-D )

You've confirmed that your carb is a round slide, which makes things super easy. Just unscrew the top cap, withdraw the slide and spring assembly, and move the clip one notch on the needle. Go for a ride and evaluate.

Awesome! Thanks! Ummmmm, move clip? Right. Move it up or down?

[Weldangrind]

Yes.



Not sure. Try a move, then evaluate. Better or worse?

I took some pictures. I can not see any way whatsoever for adjustment's
of any kind on this throttle cap / "butterfly" assembly.
I am seriously thinking I need to increase the size of the idle speed jet from #42 (stock) to, I don't know, maybe 48 ish. I have ordered a new stock idle speed jet ( so I have a backup) and when it comes in I will start playing around with opening up the idle speed jet holes.

ALSO OF NOTE: Last night after installing all the latest CVT goodies ordered, I seen ZERO gain in anything. None. Nada.
To re-explain the problem, from a dead stop at idle like sitting at one of the umpteen hundred traffic lights we have here in Paris, when the light turns green and I roll on the throttle, the scoot CREAPS forward at like 2 to 5 mph, spitting & sputtering the whole solid 4 to 5 seconds, before taking off like a rocket. SOOOOOOOOOOO embarrassing! I am saying if you can picture this: Green light, 3ish MPH until dang near through the intersection! One thousand one, one thousand two, one thousand three, one thousand four, one thousand five, GO!!!!!!!!!!!!!!!!!!!
SO, I put the original factory exhaust back on, and whatever that EPA canister thingy that LOOKS like it has something to do with EGR system of some sort, yet dumps into the CVT case. ( ! ! )
After putting the factory exhaust back on, I now have 100% power off the line back -- YAY!!! -- but now top out at 41MPH on the flats and 36MPH going up this blasted hill I hate so much going to work. GRRRRRRRR!!!!!!

There HAS to be something I am missing here.
Maybe the idle jet will remedy the issue. If not, I will be selling the Genuine (after putting the 50cc factory motor back in) and putting everything in the trans back to bone stock and selling the RH50.
After sold, I will get a 150cc GY6 , , , , , , , , something'ta'nother.
And then put those transmission parts in it!

In your 3rd picture that is the slide and needle. Remove the needle from the slide. Some of them (needles) have a 3 position adjustment. Some of them have no adjustment. If yours is adjustable there will be a little c clip that you remove and then you can change the position of the needle and lock it back in with the c clip.

This guy is good, I have watched all of his videos. This explains the needle postion and how to adjust.

Thanks Adjuster! I will watch everything I can tonight when I get home.
I fount this on the internet today. Not just a whole lot more money than
what I have spent on the PARTS upgrades alone on the Genuine!

Looks really cool!

I'm really hopeful that the needle has grooves that allow you to move the clip. If it does, move the clip down a notch and see what happens.

That said, a GY6 150 scoot with goodies would be cool.

[Louis Angel]

No groves. Un moveable without breaking apart & super gluing back together. :-/
NEW problem. As I was pulling up the drive and into the garage, I noticed 2 cycle oil on my floorboard. Upon looking down the driveway after parking the scoot, I see drops of oil like a little trail of tears going from my garage to, I am assuming, all the way back to work. I walked the "trail of oil" for about 200 yards and drips were consistent with where I slowed down. Sooooooooooo, I now have oil tank or lines or oil pump issues.
YAY!

[Louis Angel]

Several things to report.
1) Oil leak fixed. Was a cracked tank. (See pics below)
After 30+ min. of removing plastic bits where I could get TO
the tank, it was a simple repair. Somehow, some way during
this repair I bent over with the 14v. Dewalt drill and managed to
throw my back out.
2) While waiting for epoxy to dry, I piddled around with the carb some
more. I removed the jet stack, removed the main jet, found an
unknown size drill bit in the bottom of my big toolbox that I could
tell was just a weeeeee bit bigger than the holes in the idle jet, so
I drilled the 4 holes out to the larger size. Stuck the 102 main jet in
and gave the 95 a home in the growing collection box. LOL
VOLA!!!!! After I got all the bits back together (Also put the performance
exhaust back on!) I went for a ride.
NO oil leaks! No where near as much lag off the line. Still has about a 2 second stumble / stutter, but is not as hard of a lag/stutter and I can live with it like that. BUT, not going to. :-D I am convinced I have taken a step in the right direction, and if I can go just a bit bigger yet again in the idle jet and back the main off to a 98, I will have the mixture pegged!
After a 30 min. ride the plug was very black, most of the ride was at WOT.
So I know the 102 jet is just a bit too much.
Also of note, on a long'ish 2-3% Down hill stretch, I reached 57 MPH.
And was pushing 11,000 RPM! 0_0
On the flats I could hold 52, and on the way back UP that same hill was at 48.6 at the top of the hill. This is all on 6.0g Dr Pulley sliders.
I can live with that. :-)
I see often times people in various forums list a "cruise speed".
I am assuming that is a speed at witch one can maintain with only 3/4 throttle instead of wide open throttle. If that is the case, my cruise speed
would be 42 to 44 MPH @ just a sniff over 9000 RPM.

[Adjuster]

Good job man.

You're on the right track with jetting.

Try this: get yourself up to a desired speed on level grade, and then quickly release the throttle and only open it slightly. You might be able to maintain the cruising speed without being at WOT.
