Honda Spree and Elite 50 Forums

Kymco zx50 is the only one I feel safe doing 65+ really. Even at 60+ it's hairy. Check out my kymcoforums account: lovemykymco.

Also for your first ever scooter build and ownership, you have a killer awesome machine! Envious by everyone!

Very nice work indeed .Ive hit 71.3 mph on my spreedio as in sig it could go faster but ive tuned it now for 0-55mph to be over the top fast for round town .

Hi cruz. very nice tuning. I like this build, very nice.

just riding and buying parts

if you have a NCY caliper
ebc pads will fit the top smaller holes are not used
NCY 1000-1314 Brake pads
EBC SFA193HH
EBC FA193
just getting the parts together for front end swap
5339 miles on odometer

That's some good part matching! I'm going to buy a spare set as well, I'm thinking I need to order another front end set up from g9.

spark plug wire end
what do you use ??

90 deg
NGK LD05FP
#8070
or
NGKLD05F
the P means it has water tight ends
the red end is what came with my coil
and a 8mm Dyna wire

did 3 runs yesterday
changed to red contra spring
because
( the yellows last about 300 to 500 miles and than drop about 1000 rpm at crusing speed
and takes the bike out of the power band)
1 =73.3
2=82.4 didn't take pic
3=85.2
all in the 10900 rpm to 11200
the 80+ were about a hour or so apart on the same road
the bike runs totally different with the red spring
and the drum brakes are useless
need to get moving on the disc brake swap

Very Impressive. Fastest top speed I've seen on here especially at 72cc. Great build with some awesome tuning info!

hi Cruz. excellent tuning. very nice job. Great thread.

8.5s and 85 mph, not sure any one has ever done that regardless of cc. The math is a little fuzzy there. Pretty cool either way. At 86 mph I'm at 12.8k with 6.91 on a full mhr kymco zx50 block and a 120/70-12. At 81 mph I'm at 11.9k.
maybe there's a lot of belt slip I haven't noticed. How's your clutch? I know mine are toast after a few top speed runs.

12 mph jump between runs on same day at that speed. lol Now that's tuning!

so jelly i wish my scoot was done

hi,really good numbers,I'm ready start from the other side,build the stability of the bike first and the way to stop it with NCY front end for ruckus, 220mm rotors,and ncy rear rim,both with a 90/90/10 conti tire,geeting really low profile tire because the 4" rim wide,yys 230mm suspension,Now I'm start with the engine,hope can meet you number somehow

wow action ah!

couple questions...

what pulley/ramp?
what is crusing temps/rpm at 50mph with that tune?
how much do you weigh?

nice job!
