Hey boys..... I have an 02 RC51, its all stock. I want more HP. Where do I start. I'm very poor.
Trade it for a 1000cc in-line of the same year.Hey boys..... I have an 02 RC51, its all stock. I want more HP. Where do I start. I'm very poor.
Exhaust? will that help? anything else?Trade it for a 1000cc in-line of the same year.
Aside from that, re-gear the bike (15/41). You will not gain any HP but the bike will "seem" faster.
I would also do the flapper and soft rev mod.
Jesus, you'd think that a guy could get a straight answer from a forum dedicated the very bike he rides without dealing with childish tools using this site to act like total douche bags. Good job, bro.riding lessons
I wouldn'tdrop in a k&n or similar type filter.
dont believe everything you read on the internet. have you ever actually looked at the stock filters you can barely blow through them, they are overly restrictive. you just read an article from somone opposed to air filters. next youll be saying that exhausts do nothing either due to a loss of back pressure or something crazy like that.I wouldn't
Testing of aftermarket airfilters on the RC51 has yielded poor results. Typically there are no real world benefits to aftermarket filters for the RC51 as small hp gains can be obtained on topend, but only with a severe trade off for mid-range hp. Truth be told every single Honda sportbike in the last 10 years has had losses in power at some point in the rev range or even throughout it from the addition of K&N , EMGO, BMC filters etc
Flow testing on the stock filters performed by Brian Sheridan of Sheridan Racing Design proved to us that the OEM filters are capable of flowing more air than the engine can use.
The OEM filters are tuned to a specific resonance inside the airbox & once you go altering that you get various results. You might get better top end, but poor low end or vice-versa or you might get better performance with a bad stumble that lasts only for only a 200 rpm range or you may simply get a dip in power at some point. The combimation of results is almost infinite.
Honda spends more R&D time than any of the other manufacturers to insure that the intake system on their bikes is finely matched to the flow characteristics of the motor.
One thing is for certain if you are going to use aftermarket filters & get any appreciable gains from them it's going to require a Powercommader, alot of dyno time & probably some creative airbox mods too, maybe even to the point of fabricating custom bellmouths to get it dialed in correctly & you must also consider that in some cases there are no gains to be had & in many a loss of performance or drivability can Occur!
Actually I have some experience of this. I had a pre and post dyno run going from stock Honda filters to K&N's.dont believe everything you read on the internet. have you ever actually looked at the stock filters you can barely blow through them, they are overly restrictive. you just read an article from somone opposed to air filters. next youll be saying that exhausts do nothing either due to a loss of back pressure or something crazy like that.
I'm new... Just got my first RC51 a couple days ago and have heard the flapper mod mentioned over and over but what is it? Never heard of the soft rev mod....I would also do the flapper and soft rev mod.
