PoltArt

Thanks for the info guys!

@BLIZANTHIMUM - Thanks for the offer, but I don't plan to have this bike too long and it's a shared bike so I don't want to invest anymore money into it. If this would fit a 2008+ models then I might be interested after I get the bike. What do sprocket's do exactly? I don't know much about bikes or how to tune them, All I really know is exhaust + jetting it helps. And as far as jetting it goes I have no idea what to do there either. . .

@Mikey - Yeah I agree with you 100% luckily I have this 07 to practice with atm, so when I get my new ninja there will be much less chances of me crashing it.

How bout you go fuck yourself fag. I have been told this by the dearler ship and mmi certified mechanics and have watched people replace their clutch baskets and seen the damage done to them. Like I stated in my post "It is something that happens over time and won't be noticed for quite a while

katnip

No worries PoltArt everytime they start talking about wheelies there is bound to be an arguement well most any thread on here is bound to start an argument. Memories, I remember the thread about my baby wheelies now lmao Props for getting that 250 front tire up...

THUMPER

he is correct about the basket.. it will cause the fingers to get grooves, which will cause in acurate engagement.

Here is a article if you want to get deeper into it...

But basically the bigger the back one is... the faster the bike accelerates (thus popping wheelies easier) but it also affects your top speed.
The front also has the same effect but reverse... smaller = faster acceleration and lower top speed.
Think of it like a 10 speed bike....

One more thing to add, don't drop too much in the front or it will wear your chain quicker and/or destroy the front sprocket. Normally the most one would do is -2 on the front sprocket (depending upon stock tooth count). Try to stay above 15 teeth on the front.

If you want to know what your stock tooth count is visit motomummy:

I think everyone will agree that throttle wheelies will do the least amount of damage to your bike. (unless you loop it or slam the front end down) in which case you are looking at fork seals and lots of plastic damage.

JJSPRINT

Actually it's a meth Cause the "basket" gets less stress over the clutch pack.
it is rare for the basket to get get damaged.

There are usually just two things that can go wrong with a clutch:

1) It slips because it is too worn. You can tell because when you're in the powerband in higher gears the engine will speed up when you open the throttle without a corresponding increase in speed of the bike. If you have a tachometer you'll see the RPMs rise as you give the bike throttle, then they'll drop as you ease off. The only fix is usually new clutch disks, but occasionally the clutch springs are weak and can let it slip too. Springs can sometimes be made tighter by putting washers in to compress them more.

2) The clutch doesn't disengage completely. This is usually noticed by the inability to get into neutral with the engine running and the bike stopped. You'll also notice the clutch begin to engage when you haven't released the lever very far. For cable operated clutches, adjust the cable so that clutch engagement is between half way and 3/4 released. For hydraulic clutches, bleed the clutch lines and try to get the air bubbles out that are causing the problem.

Thanks for the info Hoard.

Is there a local store that would sell these or is my best shot online? I would think dealers would rip people off.


I spoke with a guy from Indonesia his name is Reza, he does stunts on a 250r and he said he has a rear 55, and front 14 sprocket set up. Is that good or could I go even better?

Also this is nothing to do with clutches, but do you guys know about jetting? I tried learning about it but have no idea what to do, I know something about altering screws, what I am going at is, after I get some parts such as an aftermarket exhaust and a air filter, would you guys be willing to help me re-jet it to get the most out of my bike?

Waldo

JJ, I would have to disagree with you. I have had to replace many baskets because of the grooves. I can show you in the service manuals of I know Yamaha and Honda where they give you a service wear for the basket and how they tell you to file them. I had to replace the RC's basket for this very reason.

lost cause

dont worry about jetting start with the sprocket switch and try that, then once u got that whole deal figured out and are comfortable with it you can start jetting the carbs. from my expriance carbs usally need jeted affter a new exhaust is installed to keep the air to fuel ratio the same just what i was told anyway

Waldo

Other mods can require a rejet but you are correct.

If you need help, let me know.

cms1172

So are you gonna have the RC up for round 2 of the loop, maybe i would be able to stop next time.

Waldo

Lets hope there is NO ROUND 2. Once was enough. RC still needs to be put back to street dress.

OOOPPPPSSSS I guess this is thread jacking. You suckered me into it again.

cms1172

you know it, but gonna have different threads next time, and I am hoping to never see another round of anything

CBRF2Old

Your right Mikey, but I understood almost all of what you said...
Don't worry about hurting the bike until you loop it, or slam the front end down. Then you may have problems. But then again, what better way to learn about fixing things than breaking them first?

r1bran

FACK! The illiterate, uneducated, know it all's and their countless misspellings make my head hurt. Remember before BHR when you could read a post once and understand it? Those were the days....

theduckllr

Yes, but THIS is WAY more entertaining. (With, or without my cartoons)

LckyTylr

Andrew, I still haven't ridden a Duc this summer......WTF?

So here's a good one......I have el stock slipper clutch on my bike......what's so funny about a slipper clutch anyone? Oh yeah, you rev 'er up, dump the clutch and funny noises ensue. What ever happened to motorcycles that would actually let you loop yourself onto your arse if you felt like it? Now wait a minute, a slipper clutch is an incredible thing for anyone that wants to race any of the main configurations at Miller, but hey!!!!!!!.......I'm riding a Motard, has anyone recently tried to back a bike into a corner by dropping two gears and dumping their fancy slipper clutch? Why no, I don't think so. KTM.....I love you, but What The HECKLE? does this make sense to anyone out there. My bike has the grunt to power up a wheelie, but when I get back that far, I'm not bringin' her back down to the front tire. I'm gonna go kick the two stroke 310 and wake everyone up in this POS subby division. Woot woooooot!!!! I mean Vrrrrmmmmm VVVRRRMMMMMMmmmmmmm!!!!!!!

I can't sleep, welcome to the club Polt Art

Wow didnt know meth had anything to do with a bike. How about you shut the fuck up seeing as how i did know what I was talking about FAG.
So much for being so quick to make me look stupid you fuck. Looks like your the one that doesnt know what you're talking about. Oh btw you talked shit about my spelling Have you seen your sorry ass excuse for spelling or grammer. My 7 yr old can spell better

Thank you glad someone else knows what thet're talking about when it comes to clutches

No s#!t

Thank you

IMO the lack of engine braking provided by a slipper clutch makes backing it in alot easier. You should be using the rear brake to back it in not the engine braking. As a matter of fact one thing I really like about 2 stroke bikes is they have pretty much no engine braking which forces you to learn much better rear brake control. It seems like it is way easier to slide in withought getting rear tire chatter when the engine pulses are not effecting the wheels rotational properties much. JMO though take it for what its worth.

stubby

Brake control is great until you lose a few toes and then can't feel anything through your damn boot. Its either locked up, or just barely dragging

Matt

Crack man... You're on friken crack... I love my slipper on my sporty

LckyTylr

I honestly don't know anything about backing it in other than what I have read (above). I really don't think it would be a good idea to lock up the rear tire on asphalt and then suddenly release, power out......at full lean with a foot out. I don't enjoy highsiding, unless I'm witnessing/not participating. If you have done this and know that it works, then I want to watch and learn. I'd love to tard out my dirtbike, but it's a two stroke.....and as you mentioned.....no compression braking.

theduckllr

Haven't got to ride a duc this year? Quit your whining and head over~! Geez! As for backing it in, I'm a big fan. On my Burg, it was just too easy to bang down a gear to get things sliding, square it off and power out at the apex. Scares living crap out of the guys on the outside, but worth it everytime. I can't imagine doing it consistantly with the rear brakes if I had a slipper. That sounds like a free trip to the emergency room, just waiting to happen.

I didnt mean locking up the wheel and then trying to spin up the wheel to catch back up to the slide.

I like to drag the rear brake so that the wheel is spinning slower than my ground speed so the back is loose but controlled if that makes any sense and then I use my body to initiate and hold the slide stable. While I do that I downshift to whatever gear I need to be in on the way out of the corner and then keep the power on a little but not enough to fight the rear brake much then as you let off the brake and begin to roll on the throttle the power is already on enough to keep the slide going until you straiten out enough to really get on it.

That is how I do it on dirt and supermoto bikes 2 or 4 stroke. I always use the brake to control the rear end and down shift as I slide to the corner and be in gear and on the gas before start letting the brake off. I am no pro or anything so take it for what it is worth. I am sure there are other ways of doing it that are just as effective, this is just what works best for me. But for the record the only type of racing I have ever done is flat track on both quads and bikes. Fun stuff! I am going to flat track my 250 when I can afford to get the setup needed to do it well.

LckyTylr

Damn, that sounds busy. I'm very impressed. do you still have a pavement worthy bike that you are willing to back it in with? I want to learn from someone that knows what they are doing, or at least see it. I'm still pretty convinced that the easiest way to do it would be with compression braking but hey, I at least want to see it done.

stubby

The Supermoto guys at MMP have the rear wheel locked up, while banging down 3-4 gears. The ass end is already sliding around when the clutch gets released, slight throttle till the apex then they are back on the gas. I can't tell you what they are doing with the front brakes, but that rear tire is skidding for a good 20' going into turn 1.

IDAHOBALLER

It is hard for me to explain how I do it in words. Its not really something I think about, its just something I do. Thats just the way I like to ride. I like to steer a bike with the rear end more than with the front.

The only street machine I have now is my SV which I dont really slide around too much on. When I sell my SV I want to get a supermoto bike though. I have never ridden a bike like yours, all the sumo bikes I have ridden were full on mx bikes with 17 inch wheels, race tires, and a big front brake more or less. We can always just go somewhere on the dirtbikes and find some nice corners to practice sliding into and through!

Yup, thats how I like to do it. That is how I learned to ride when I was a little kid since I grew up on 2 stroke bikes and it transfers to asphault just fine for me. The back slides way easy when you have the front brake on hard so that the weight transfer is mostly on the front end.

CBRF2Old

I learned how to "back it in" with a 1965 Impala...brakes, slide, power...
