Input on Buddy 50 build

Post by RockMysim »

Hey I want to hotrod the Buddy 50 to go 50-60 MPH. I have a stock white buddy 50.

Parts List:

YASUNI R EXHAUST HORIZONTAL MINARELLI '02-'11 ZUMA BUGEYE
MALOSSI 19MM DELLORTO CARB KIT FOR STOCK MANIFOLD
STAGE6 CYLINDER KIT "STREETRACE" 70CC CAST IRON
Malossi Multivar Variator for Genuine Buddy, Roughhouse 50
Valvoline Multi-Vehicle Moly-Fortified Gray Grease 14.1 OZ Cartridge
Dr. Pulley 16x13 Sliding Roller Weights 6.5 Gram
Honda Hondabond 4 Liquid Gasket 08717-1194

Is this parts list optimized or can I do better on things like the variator, roller weights, carb etc? The Yasuni exhaust will be derestricted. Will also take the snorkel off the airbox. After these mods, should I mix oil into the gas tank? Can I go without it? What's your recommendation for main and pilot jets? Thanks in advance.

Only adjustments I can think of:
Get a set of tuning rollers. Find out what works best before buying the final set.
Why the Vavoline multi-grease?
Carbon fiber reeds are cheap insurance.
I'd run the stock airbox with the snorkel removed as well.
It's been so long since I did a 2-stroke I can't recall what base jetting you should start at.
I like the Yasuni exhaust. I think I had a Z that I derestricted.
I also ran the weird 17.5mm Delly carb. I should have used the 19mm but I didn't want a gas station hopper.
My Zuma bug-eye oil pump worked perfect for setup. Let me think what it was.
Mallosi Street Race cast 70cc.
All port matching and polising done by me.
MotoForce full circle crank.
Yasuni Z derestricted pipe.
Malossi Multivar 2000 variator with stock belt.
Up gears. Forgot ratio.
Reused stock rear pulley assembly. White spring and spring seat bearing added.
Stage 6 3 shoe clutch with easy access shoe spring windows with matching Stage 6 bell.
Carbon fiber reeds in stock cage. Forgot stiffness.
17.5 Delly carb. No idea what jets or slide.
Manual choke conversion.
Stock timing and stock CDI.
Stock airbox with snorkel removed. Malossi red sponge filter.
Was good for 60mph max all day full throttle and wheelies with minimum tug of bars. Rode it EVERWHERE and got just under 6000 miles on it before soft seizing in the dead of winter from being lazy and not upjetting.
Ran a STIHL tach and a Trail Tech CHT reader.
