Derestricting the Kymco Super 8 4T?

[Super8504T]

So your saying an 87? What kind of speed would that give me with my Polini variator/clutch?

[Luke.]

ahah, i will soon be drawn into the lethal addiction of modding
yeah super, take art's advice too, 82.5 would be fine, i'm not sure how much the MPG would go down per size though.

[Super8504T]

Ah I no! Im not getting carried away though.. just doing the things I need to get 50+ 

My decisions have told me to go for size 85  Might as well do the job properly and get some improved performance!

I can't say for sure 50+ is common,You want to have a veriety of jets I always order 3.Your elevation,tempurture and weather can affect your performance,so what works for me may not work for you.With a veriety You can adjust for your scoot and not be stuck waiting on another jet.Try them all you might like one over the others and do yor plug chops

[Super8504T]

Ok thanks a lot for your help art 

I'll report back in just over a week when I shall have received all my parts and have them fitted!

[Luke.]

good luck

Just trying to get more speed 

Can you use Shell V-Power on a 50cc? Its high octane fuel. Just thinking it would give me better performance. But I've heard your not suppose to use it on 50's is this true?

[Luke.]

super unleaded(high octane) isn't very good on any motorcycle really, just stick with normal unleaded, high octane will make your bike run horribly, i had to use it before because that's all the station had, big mistake.

[Super8504T]

Ok cheers.

I use Shell V~Power in all my bikes, Suzuki Boulevard C50, Suzuki GS500, Kawasaki EX250, Kymco ZX50. They run well and that fuel improves fuel economy. The only down side is that it costs a bit more.

[Luke.]

i thought for 250cc and under it just dropped performance for bikes, because it's too rich for the engines

[sidthesloth]

I haven't heard anything like that, when I first started using it was on my Yamaha XV250, no problems there either. I think too low an octane rating will give problems. I don't know the specifics, only what I have tried. When I bought the Boulevard in Adelaide I filled up with normal unleaded, 91 ron, low fuel light was on @162km. Since using V~Power I am passing 200 without seeing the fuel light, the last time I saw it was a while ago and that was two up at 216 kms. If you are concered about using it you could try to find someone who knows more about it to fill you in on the details.

[Luke.]

oh my dad as a kawasaki ninja 600, he seems to think high octane isn't very good on motorcycles, especially 50cc's, i've had both in my bike and how my bike runs when it is filled with high octane is much poorer to when it has standard octane.

I have to chime in here. Octane is equal to the flash point of the fuel. Hi octane takes more heat to ignite. Pre ignition is caused from fuel igniting before it is supposed to from the heat inside the combustion chamber. That burning fuel will prevent the stroke from continuing at its speed by exploding against the piston/head. The pinging noise you hear is the same as hitting the piston with a hammer. Sooooo Low octane fuel is the ENEMY of high compression, high revving air cooled engines. Everyone can have their own opinion, but the FACT is Hi octane fuel in our scoots is mandatory. If you want to put your scoot out behind the shed in a year or less by all means run regular fuel. If you want to run it for the next 5-7 years, before major repairs... Use the BEST fluids you can find. Gas/Oil/Brake Fluid ect.

I use Shell V~Power in all my bikes,

..my scoot runs like crap on anything lower than 93 octane..

..Shell V-Power is my fuel of choice....
