K&N Air Filter Queries and Doubts

[s1d]

Hum Hum ! I see ! Got it now !!! if I Reduce down the weight or the Variator it will spin faster giving off better acceleration ! And if I over do the weight I'd get more top Speed And Do you know the Weight of the Aviator's rollers ? And I saw Dr.Pulleys also They are nice btw

And one more Question about it ! If I do change these weights And get K&N filter Will the performance Increase ( Marginally of course )..

Thanks !

i do not know the weight of the aviator's rollers (but i assume it will be either 10g or 11g) and another thing to remember when you buy after market rollers is their dimensions, for eg. 16x13 is the dio's dimension. you do not want to buy the right weight but wrong size
the advantage i have with the dio is i can compare the parts with the UK model (called the honda scv 100 lead, which is the dio that is/was imported to UK)
doing the mod you mentioned(with 1 gram lower weights) will give you a bit of a push at low end (if you just richen the mixture without upjetting)

if you read that link you would understand the effects of changing the weights of the rollers.
rollers/sliders - different name same thing/function. but yes, rollers are the round ones(that come as stock) and slider's are the ones that have a flat side (like dr.pulleys slides), and there is a lot of debate on the advantages of sliders vs rollers (guess its like the coffee bite argument) - i haven't had any issues with the rollers & haven't used the sliders so cant comment on them.
rollers are easier to procure and cheaper than sliders. the trick is to find the correct combo of roller weights and clutch springs for a nippier pickup without affecting the 'top end'. (because if your clutch springs/shoes are worn out and you experiment with the rollers you might not get as good a result as with a clutch in proper condition)

check this out Scooter variator - operation principle - YouTube
this is exactly how its looks and functions, if you notice at 11s on this video you will see the clutch engaging with the clutch bell(the outer thing that you see rotating) the engine spins up initially (the front is the variator mechanism with has the rollers) and only at a certain rpm ( what you do by changing the roller weights is changing this rpm) the clutch engages and thus transferring power to the rear wheel)

Like i have mentioned on the honda activa/dio/aviator ownership thread... these filters are just a waste of money. replacing the stock filter every year/8k km and cleaning them every 1500-2000km is the norm for these scoots with paper type filters.
if you want a small bump in performance without any major mods done on the engine, the safest way would be with installing lighter roller weights and stiffer clutch/torque springs (dont over do these, just one step up/down and check the performance).. i will let you know the availability of these stuff soon.. though i got a pack of roller weights from usa thru a friend, i have located a ebay seller with pretty economical rates and will let you know if it works out procuring from them.

Pros:
1. Your scooter will feel faster.
2. Your scooter will make more noise.
3. You can buy new scooter/bike/car sooner.

Cons:
1. Your scooter may feel faster but its most definitely not. It feels so due to the added noise it makes.
2. Since you will be running a lean mixture, Your scooter will overheat.
3. The valves will go kaput sooner rather than later due to this overheating.
4. Cleaning a K&N filter is not exactly cheap if you use the correct stuff.
5. With no actual performance benefits, its hard to justify the cost of the filter over stock filter.

Myths:
1. Adding a K&N filter will not add 1-4 bhp to your ride.
2. Even if your mileage increases after filter swap (*highly unlikely*), the added maintenance will more than exceed the savings from petrol.

If you need an unbiased opinion of a person who actually used K&N filter for extended periods on his bike, please go through this post

Thankyou for the reply Antz
like your Pros
I have recently bought R15 so.. No new vehicals for now atleast a year !

1) And I was thinking that The mixture will be lean but I can Re-Tune the Carb and get the mixture to perfect balance then will the engine overheat ?
2) I know that 100ccs cant be more faster with just Air-filter changes so.. That thing Is well prepared for !

3) And of the maintanence costs I can do some monyshedding Because I really dont drive Aviator to long distances and milage is the least thing I expect from my vehicals

Want to add K and N universal filter to my TVS Star City.

Hello all,

I would like to add this filter to my Star city as it should increase some performance and mileage. Will it create any issues to bike's engine ? I also want to know how to install it on my bike.

Thanks in advance.

Make sure you oil these cotton filters, Don't run them dry, straight out the box, Unless you want to let dust into your engine.
There is a small satchet of oil, red in color included.
Make a tiny pin prick in the tip of the teat, slowly squeeze it onto the peaks of the filter ridges while running it down the length, Don't over oil or it will just drip off and pool up.

If you do this then you will eliminate the dust problem, the dust sticks to the oil in the filter.
Should you be riding/driving in very dusty areas, get a old sock, and cover the filter if it is a cylinder/cone shape/universal filter as a primary barrier against the larger dust particulates.
If its a airbox type then work out a way to use the sock to cover the air inlet, or you will be constantly complaining about the filter being dusty.

Get the cleaning kits for these filters, It has solvent and the recharge oil. DNA, K&N are interchangeable.

Lots of mechanics are advising against using K & N air filters,saying they are not suaitable for our dusty conditions,K & N increases air flow to the engine but don`t filter the air completely & it is harmfool to the engine in the long run cause lot of very fine particle dust is always present in the airfilter track.
This fact I have seen in my father`s car so I can also vouch for it.
So how about bikes ?
Can any knowlagable person shed light on it ?

try uni foam filters it has better purifying ratio compared to k&n...
