Post 2005 Zuma First Mod Advice
So I just picked up a 2005 Zuma with about 3200 miles. It’s all original and in great shape. I want to do some simple cosmetic and performance upgrades! Any advice on simple starter mods would be great!

Is there a way to mount a phone on the bike without upgrading the handlebars? Also, can I updgrade the exhaust without messing with the carbs?? Thanks!

You could try and cut some of the gauge cover plastic to allow access to the handle bar, assuming your willing to damage the cover. If your completely stock as I was then I would upgrade to a malossi multivar 2000 variator and some dr pulley sliders. The weight of the sliders would depend on your weight and mods. I would also get a sport pipe (I have a polini scooter team 3 on stock cylinder) and oem mainjets 82, 84 from yamaha to tune the carb for the new pipe. Replace metal reeds with carbon reeds as soon as possible if you haven't done so, it will save your engine. Make sure to clean and regrease your front and rear pulleys. You can upgrade to a zuma 08 to 11 rear pulley & clutch for smoother performance. Also install a contra spring (white for stock cyl.) which should be included in your variator kit. Add a malossi torsion controller (yellow cupped washer) to the spring for smoother performance. Get a set of malossi clutch springs to raise up the rpm point at which the clutch grabs to match up with the higher revving pipe. Otherwise, your take off will suffer. When clutch is adjusted, it should rev up then roll to about 5-10mph then take off nicely. Again this setup is if you plan to keep it mild, adding a 70cc later will need a slightly different setup. Figure out your long term goal then buy parts based off that.

On my stock zuma, I could barely hold 38mph up right on level ground, no wind. I weigh 185lbs. Tucking would get me up to 43-44mph. Now with my polini pipe, 82 mainjet in stock carb, 08 rear pulley& clutch, white contra spring+torsion controller, athena carbon reeds, multivar 2000 +6.5g sliders, I hit 40mph quickly up right up to 41-42mph. I can hold 39- 40mph on slight up hills upright as well. Tuck speed on flat ground is about 45-46. It was very noticiable to me the change in pick up and top speed. Tranny tuning is very key, tinker until you feel the difference.

Thanks! I’ll def look into those upgrades, what’s the cost of these things? And how hard are they to install?

My scoot has similar performance numbers (as far as acceleration and top speed) to Supasupafly but I did the 70cc Malossi cast iron and an 82 main jet only. Everything else is stock.

Just something to consider. Regardless, enjoy!

Don't go mild... GO FULL BORE! No hold backs! Quadruple liquid cooled cylinders with pop up pistons, 58 mm pumper carburetors, turbo charge that 2-stroke, ceramic muffler bearings, up gear that banshee to go 88mph so you can travel to the future and report back on the electric Zumas. :cheers:

If you are mechanically inclined the BBK with carb upjet improves both top speed and acceleration .
The pipe is easier to start with and improves top speed or acceleration depending on the pipe .
BBK Malossi Polini Top Performance cast iron for sport set up are very popular on here $150-$200
This will give you the power to push bigger gears either 15/50 or 14/42 $100
Up jet Stock carb
84 main part #14T-14343-42-00 82 main part #14T-14343-41-00
I would buy both start big plug chop and work way down available from Yamaha dealer $10
Pipe either stay stock it is already unrestricted
or upgrade The pipe to let the bike rev higher and increase Top end $150-$200
springs and rollers if needed for stock clutch and variator
you can go bbk first or exhaust both require a up jet on the carb
jets are cheaper then a new cylinder
