K&N upgrade

[Dark13]

ok with everything being stock how large of a main jet should i anticipate?

and on an older post i saw something about another line the needs a filter if you remove the stock air box if there is can someone post pics?

Not sure on the jet, but a lot of that is trial and error to begin with.  I think the extra line you are referring to may be the crank-case ventilation.  It really just comes down to having to put a filter on any additional lines leading from the air box.  Don't just plug them!

[wordslinger]

..i wish i could say what jet you're gonna need...but it seems my scoot has always ran a larger jet than most ppl here...

..just do plug chops as you go, and trust what your scoot is telling you...

peace

Mine had a K+N it had an 88 jet and a washer under the needle, I put it back to stock but thats how it was.

[Dark13]

whats the easier or better way to go about the fuel mixture going with a jet that works or messing with the needle? and could someone post pics of the needle your all referring to?

and what size range should i get 88 - 110?

[zombie]

The needle is for metering the fuel from about 1/4-3/4 throttle. The main jet does the 3/4-full throttle range. With just an air filter mod you should be able to get away w/ 2-3 sizes bigger than the stock jet. http://www.flydiver.com/HTML/Delorto%20Carburetor%20Tuning%20Guide.html   This site has more info on the basic carbs. we all run. The needle runs into the main jet, and depending on the size/setting it will alter the fuel flow through the jet.

so what is the stock jet size?

also did you mean i will only need to up the jet a couple of sizes or will i have to mess with the needle

also what k&n should i get and is there a place that sells tuner sets of jets for a decent price?

[Dark13]

found a site that has some cool stuff maybe this will help someone else

also a thought just hit me what happens if the k&n filter gets wet?
like when im riding home in the rain

[sidthesloth]

When I park at work (a very dirty place) and when I wash it I just slip a stubby holder over the filter, is a perfect fit.

so what is the stock jet size?

Stock main jet from the factory on an A50 is an 80 if its restricted, an 82 if not.

[Dark13]

yeah but what about when i ride home in a heavy downpour

[zombie]

It has never been a problem on mine. Just stay out of the deep stuff. I also spray PB Blaster on it about once a week to repel water.

[Dark13]

oh OK didn't think of that

cool thanks for the info

i requested a week off for labor day so unless something bad happens i will have a new paint job new filter new jets and one bitch'in ride 

and a high performance clutch kit (if i get lucky)

which kinda reminds me do you guys think that a 1k rpm contra + 5grm rollers + some slightly stronger than factory clutch springs would work with my stock setup? and what kind of enhancement could i expect

[zombie]

That set up will give you more rpm's and a quicker launch/midrange. You will be cruising at higher rpm's but I think the difference is well worth it. One thing to be carefull of is if you use any 1 part spray can enamel they are not fuel proof. Lacquer, and urethanes are.

[Dark13]

oh i know there is a clear enamel that I'm going to get for a top coat

so what is involved in modding the needle?
