Cobra S4 questions....

Hey guys, I had a few questions for whoever has a cobra S4 or a quad in general. I am new to this whole seen of pocket quads and I was wondering anyone had any mods done to theirs or if they know if the bolt on mods will make a difference? What mods should be considered and where's a good place to get them? I just want to be realistic with the performance aspect before purchasing. I spoke to a person on the phone at pocketquads and they stated that the quad is pretty much maxed out stock! Is this true?

Thanks a ton!!!

i just got my cobra about a week ago (after waiting a month because it was on backorder). first of all it is very fun. i really enjoy it. the only mod i have made is a hp air filter. about the mods, you can get anything that fits a 47cc cag. i am pretty sure they are the same exact engine. you can get the parts from davesmotors.com. they are very reliable and have fast shipping.

Thanks for responding.....how fast did it go right out of the box? Did you feel any difference in performance by putting on the air filter? Thanks- D

i have not gone full speed yet because i am still on the break in period. so far i have been using it for 'stunts'. catwalks and bicycles are very fun on this quad. about the air filter, i could not tell much of a difference, but i know it allows the engine to 'breathe' easier. the air filter also goes well with many other mods. if i were you i would make my first mod an hp air filter from ddm.

i just bought this quad as well, waiting for it to arrive gonna hook it up with alot of mods ill keep ya poster or u can suscribe to my threads thanks

how fast do these cobra s4's go and how big are you guys im about 190 and 6'3'' and im looking to get a s4.

Hey....I have had some problems with mine and I only weigh 165. They are pretty fast and alot of fun to ride. If you do decide to get one dont buy it from Pocketbikesunlimited.com!!! When my quad came...the frame was bent and you couldnt ride it full throttle. It feels like it is going to throw you off! If i could take it all back id go for the 110cc!!!

110 cc pocket quad i havent never seen one

^TBH, if you did some frame work, ect...you could probably fit a 110cc engine on there.

Seriously? Any info or pics on how to go about this?

im def getting this quad not doubt, one i sell my peice of $h!t chinese pocketbike =) lol

Well i just got a cobra s4 and every time i try to go full thruttle it stalls out what should i do?

you have to break the motor in. You shouldn't go full throttle for 4 or 5 tanks of gas. I went about 1/2 throttle for 5 tanks, mixed 25:1, and now I run 50:1 and the quad rips.

Does anyone know what motor comes with this quad. MPR & others advertise it with a 49cc. But after looking around this site, it appears it has a 47cc. I bought mine from MPR. surprise, surprise no one there has a manuel.

any one no how to fix a pocket quad from bogging???

hey i just ordered my cobra s4 mini quad im 5'5 and 100-110lbs whats the best break in meathod for its 47cc motor? and can anyone tell me anything about this pocket quad? ive seen a few videos of these things and they look supriseingly fast.

hey i just ordered mine too it should be here by the 13th of this month,i was wondering if you got yours yet and if you did just wanted to know how it is. wat r the pros and conns etc thanks i appricate any help!

my daughter has a cobra s4, my husband and i ride it and my husband is 270 lbs and 6'2 and it rides real good, although something is wrong with it now, when you start it up it takes off by its self....without even touching the throttle, does any1 know what this could be?

broken clutch spring or an air leak causing the engine to rev up.

spray wd40 around the engines intake set up if it drops in idle theres your leak.

take off the clutch housing (has a small pinion gear driving the chain) and check to see if theres a loose or broken spring on the clutch.

yeah its gotta be a stuck cable pulling the barrel open in the carb causing it to accelerate on its own,or just like the other person said a broken clutch spring could also be causing this probelm if you dont have a local shop wich u can purchase replacment parts "if needed" i highly recommend partsforscooters.com im a constant customer of theres and they have pretty much anything that you may need.good luck
