Jetting Recommendations

[Greg]

Night and day difference from 85 to 88.
I'm taking good mental notes and I am going to start writing things down. I'll be doing this all over again next month on my other scoot.
The jets (85 to 88) are pretty close in size, so to feel that much difference was such a great surprise.
88 is my biggest jet, so I sent an email to Sherryberg to find out what she has for 6 mm DelOrto jets from 90 to 100.
I have to try at least a 90, but I think I wouldn't mind trying a 90, 92 and 95. My plug is still reading light brown so I want to find out what jet will make it too rich.

Is it normal for the scoot to sound louder at 1/2 throttle as opposed to full throttle? I think the noise through my air filter lessens at WOT (could be due to going faster though).

[Greg]

I put the rest of the plastics back on yesterday.

"Honest officer, it's stock 49.5cc. Yeah, that free flow air filter sure made it louder!"

Good lookin' scoot. If you ever have the rear wheel off for any reason, can you get me a few pics? I'm just curious what it would take to get a disc on mine. I've never had the privilege of seeing this style of engine with a rear disc in person.

Nice ride! Rear disc rocks!!!

[Greg]

Thanks guys.
The roads are sloppy from the melting snow and the scoot is getting dirty, but I'm having fun tuning!
Pics of the rear wheel? Absolutely.
I have a little clatter in the rear caliper (probably worn pads) so when I take that off in less than a month, it's one more nut to take off the rear wheel.
I have been curious about this too, wondering how the heck I could upgrade to a 90cc motor and try to keep my rear disc.

[90GTVert]

Thanks! Looking forward to seeing it. Hopefully for you it would just be a matter of swapping parts form the stocker to the 90cc. I guess the small transmission case half is different and the output shaft is different and of course the wheel is different. Hopefully it's something that can be swapped easily.

Be careful out there in that snow. Around here the road will be clear for a while and then you go around a blind corner and there will be 4" of snow all of the sudden. I think the the county roads crew has stock in the local body shops or something.

[Greg]

Brent, I think you guys got more snow than we did this year.
You guys got nailed!
Last Tuesday we got about 7 inches of snow. It has been over 40 every day and there are only little patches left.
There's no snow on the roads, just a combination of dry roads with some puddles of salty water and sand.

I normally only drive on dry roads and above 50 degrees, so I have been treating the puddles as if they were ice (go straight through, do not hit the brakes).

And Skip, if you are still around. Is that picture THE Beamer you put together from boxes of parts? If so, wow. Awesome job.
I saw the thread in another forum. It came out great.

[90GTVert]

Gotcha. We're getting to the puddle phase after a 48 degree day yesterday and there's supposed to be rain this afternoon or tonight. My jacket and scoot are a mess from those nasty puddles though. Unlike me, you were smart enough to keep your fenders.

Yep... thats the 1 Thankx for the compliment
From this

To this


It was my 1st 2t build
Everyone on this site really helped me through it
Thanks guys
I am having an issue since I installed a Dellorto 19mm though
I had it screaming with the stock airbox & carb (85main stock pilot)
I currently have the Dello with a 92 main and unifilter with a cf cage (larger openings)
It is hard to start and I think its too rich (plug gets wet)
It could be the remote choke setting
The snow is melting finally here and I haven't had it out to dial it in yet

[Greg]

Does sound like the new carb is dumping more fuel in. On top of that, it's still cold enough where the scoot should be running leaner (than if it were over 50).

I got bored so I yanked my rear wheel off. I had to remove my exhaust too. It's OK, I was bored enough waiting for a call back so I couldn't ride anyway.

I'm new to photo bucket and posting pics from photo bucket. Hopefully you'll be able to get what you need here.

Looks to me like the rear disc setup requires new rims, a new gearbox cover and possibly a new shaft.

[90GTVert]

Thank you very much for all those pics. Great work. I think you're right. I need to look into those parts though. I have a feeling to get all that plus the rotor, caliper, hose, and lever it might be more than it's worth. The rear drum really isn't bad enough to warrant what may be a multi-hundred dollar swap.

[Greg]

No problem on the pics. I'd rather take too many than not enough.

Yeah, it'll probably be cheaper to find a broken Redstreak M-80 or Motorino Supremo.
I feel like I stole that Wasp back in November. It's in excellent shape with 1000 miles. It had a bog and I was told it may need a carb.
The dealer took it back from a customer as the customer couldn't figure out how to keep oil in it (what??). Owner had it in for service before to clean out the oil tank, clean the carb, etc.
The dealer told me he didn't trust the oil pump as he didn't know what the owner put in the tank.
Long story short, the top end had seized and was short of power. I tried to revive the oil pump and it would not re-prime. So the scoot cost me 400.00 and was the perfect candidate for a bbk and permanently disabling the oil pump.

I have looked at impound scooters here. There's a garage about a 1/2 hour from me that will buy impound scooters and then try to sell them for about 500.00 a piece. They always look the same, like they have been stolen and the plastics are trashed.

Good pics! Thanks for posting them...
A rear disc swap would be nice!

[Greg]

I'm sure the different gear box covers (disc or drum) use the same bolt pattern.
The 13" wheels with rear disc setup may be more common on a 150cc. I know my style scoot comes from Jonway as a 50 or 150. The 150cc might be a different gear case cover.

So, I finally got an answer from Sherry Berg on jets. I guess they take the New Years holiday celebration to the extreme in Singapore!
She told me she had main jet sizes 90/92/94/95/96/98/100.
Of course, I gave her my standard reply, "I'll take two of each".
This will put my total to 22 jets for $22.00 shipped. It sure beats $5.00 a jet.
I should be back to tuning next week depending on what this "Snowacain" does.

[90GTVert]

Never thought about wheels from a 150.

Nice selection of jets.
