lol that would have to be a hel of a warp..lol

please explain how a warped plate or a grooved basket cause proken fibers?

Are you running asphalt? this always happend to me when i first started clutch tuning.. its mostly caused by tire shake or a spin then hard hook condition. the fix or one of them is in one of my post in the lock out tuning thread.. if you cant find it pm me.. Chris WheelmanChassis

well hell i dont even have a chance then.......

your the one that made the first gay post...... just sayin.... Ill bring my dyon slips you bring yours.... that will be the proff i beat you on a less powerful bike with a heavier rider..lol all this will be over soon....... well the race will the shit talk wont hahaha

iI will be harping the shit outa this 350 all weekend. well at least till im in front of Jaycll then ill be giving him the YOU LOSE BRRAP BRAP at the end while doing the stanky leg! cheers! Chris

dang lindz cant us slow guys have any fun lol ms. 110lb jockey! this smack talk is a blast.... got my taste buds working.. hahahaha Slim

As far as clutches and steels go, I personally like to stay with the same fibers always. Any tuning i do as far as steels go is strictly thicknes and finish based. (finish of the steels can be altered for diffrent outcomes) but are very minimal in my experiance. (I also get into cutting the O.D of the steels on the inner most of the stack up) Ill explain in further discussion. In my experiance, I have good luck tuning fine increments with the pack stack-up height. With that being said to help you guys just a little bit, as the clutch pack ht. gets taller the pressure plate will come to rest at a shorted installed height as far as the spring goes. This change in the height increases the static/base weight that is applied to the clutches. The air gap in the clutch can also be used to effect clutch tune-up,but i hope brian will shed his own light on all this before i say any more lol This knowledge can be very helpful after the clutch starts to wear. I try to map out my springs in .005 increments,so as the clutch wears i can add base pressure to compensate for a taller spring installed height. This will help you be a more consistant racer come the final rounds of elimination.. Hope this gets us rolling a little bit.... Great thread... Chris WheelmanChassis

yep your 14 mil crank will prolly be in it lol

if its stock stroke bring it on lol

No excuses here, i will take a azz dragging like a man and also give whippins like one .... ill bet money that frame you have is lighter than mine also its not brand new..... its all used, ebay, craigslist parts. Remember its my girlfreinds bike! its a hjr dune port bought directly from a member on here with a lil stock crank from a 05 i welded... and some drag goodies. do all end all im 300lbs! strap a prego suit on when we race then it will be kinda fair,, slim mmmmmm i taste the ribs already!

bahahaha with a bad ass RDZ super dyno qween motor, the lightest stock chassis ive seen, a professional tuner helping ya tune i SURE hope you beat me. BUT, I have been victorious as the under dog many O times. Ill have my mid 70 hp dune port motor in the ol ladys chassis with my 300= lb ass riding.. may the better rider/tuner win. now joes got me thinking... i may change my request to a big azz slab of ribs.... still with a sweet potato though.. 350cc game on boys... i say winner gets tore down for bore/stroke verification............. just sayin wink....wink cough.....JAY hahahahahaha

im thinking of bringing the 10 mil in a crate, and swaping the motors out after i win my first steak dinner. Then winning some king crab legs from mr. Jaycll.! lmfao! slim

I like my porterhouse medium, with a sweet potato! lol mr wheelman never heard that one.....

We will be there with the ol ladys 350cc drag bike and the 450.... funny how the chassis guy cant even get a chassis for himself together lol Im callin you out Jaycll its on!!!! battle of the 350cc stock cyl bikes! slim

hmmmmm.sponsor?

We will be there , hope to have a great turnout . This event has been great fun, and fred and the guys at us27 are awsome hosts... Chris WheelmanChassis

Ok, so after you get the base weight measured and a baseline arm weight put on to start, all things recorded in my racers log its time to go to the track. I say its best to start with the same setup/tune up that you normally run as a baseline with the only differance being the clutch, this will give a better idea of what the changes have done to your times. So, I roll into the beams, reach my desired launch rpm the lights come down , I dump the clutch and bbbboooooooooggggg!!! Now assuming my gearing is right for speed/rpm in high gear at the end of the track, and my launch rpm stays consistant. Whats the next change these guys trying this should make? IMO, I would reduce the amount of base weight on the clutch resaulting in more "slip" for the initial hit. OR If I belived the bike was very close to making a clean launch, I would raise the launch rpm at the line. Now with all this being said, If the bike did launch it would most likely suffer from excessive tire spin needing further clutch adjustments. Bryan from your exp. what would the proper adjustments be, and how do the people reading go about these changes, and in what increments do they do them in for best results. Chris Wheelman Chassis

A slider is a centrifical style clutch used in a very good amount of drag racing motorcycles. It uses engine rpm to to apply the clutch using weighted arms much like a standard lockup, only differance being a std lockup is hub driven. A slider is more applicable and benificial in a situation when traction is very consistant like asphalt. my .02 chris WheelmanChassis

micropolishers........

Looks great glad you liked the bars! chris

Joe and myself are hoping to get a bunch of dates for phils this year, as well as a no wheeliebar race going... Chris

Brian, from your experiance whats the most important tips to setting initial/static- weight/pressure. Also for the guys trying to grasp this, is it better to start light on the base pressure and move up to achive the proper initial hit or start heavy and drop the pressure. (im assuming starting light will be a fast death of a clutch for most average tuners). Im hoping this thread will take off.. Chris WheelmanChassis

In general, more traction - more weight Less traction- less weight. Assuming all other variables stay the same.

Any time sir, it was my pleasure. ill keep checking in here and ill add my .02 when i think its relivant and ill keep the questions coming. Chris
