headshake, im getting some at hard acceleration around 80-90+, is it the s3 bars the previous owner put on it? tire pressure is good, bearings are good. has anyone used a street cone in their force products pipe, did it make a big difference in sound, performance? p.s. dyno run tomorrow night! race ecm, force pipe, k&n carbon fiber filter, can anyone predict numbers? | ||

My X1 is very stable at those speeds. Are you leaning into the wind or hanging back with your arms straight? Keep your arms bent and let the wind hold you up. Check your front tire for cupping by running your hand across it. | ||

MY TIRE IS BRAND NEW IN THE FRONT, BUT I THINK I AM LETTING MY ARMS STRAIGHTEN OUT AS THE BIKE PULLS AWAY FROM ME. THE PREVIOUS OWNER MODIFIED THE SEAT AND ABOUT MADE IT FLAT, BUT MY ORIGINAL STOCK SEAT WITH THE LIP ON IT FOR THE PASSENGER WILL BE HERE IN A FEW DAYS, MAYBE THAT WILL GIVE ME THE CONFIDENCE TO HAVE MY BACKSIDE ACTUALLY AGAINST SOMETHING. I THOUGHT IT COULD HAVE BEEN MY ARMS BUT THOSE S3 BARS KEEP MY UPRIGHT, IM GOING TO PUT THE STOCKERS BACK ON ASAP | ||

That street baffle has little to no effect as far as I could tell .. I have one on mine, probably more so just to say there is a baffle if the authorities question it due to the loudness ... | ||

i was getting a head shake just from the force pipe, that's why i took it off and put the supertrapp on. that is one loud pipe. | ||

I'm VERY interested in what your dyno numbers are as my bike is basically the same. | ||
| Limitedx1 |
i will be putting her on the dyno tonight! i thought my old s3 high bars could have been the problem, but i put the stockers back on and made sure i was pulled up on the tank and still the same result. i checked my head bearings and all felt right, i didnt check the wheel bearings yet. are the head bearings cheap enough just to replace? | ||
| Natexlh1000 |
Your problem might be in the rear. Make sure your rear axle is lined up ok. The rear belt should be floppy loose too. | ||
| Limitedx1 |
the belt is perfect, i can check the axle location. could it be suspension setup? i am very light (130 lbs) the guy that used to ride it was 200. should i see the manual and adjust it to my weight? the front end is going to be light with anyone on it under acceleration though, hmmm.... i think even if i do get it fixed that a dampner will restore my confidence | ||

I'm guessing around 83 rwhp and about 90 fpt, I may be off some on the torque, I have my dyno run at the house that I did a few years back. If your much more in the HP range I want to know. The day I ran mine at Chillicothe Easyrider's Rodeo the guy said all the Buells were within 5 horses of each other. I believe there were about 8 that had run. | ||

FWIW: I had a head shake that came from from a bad tire. Took a while to figure out because it only happened leaning on hard accelration. Scary when it happened though. Are you using Dunlops? | ||
| Limitedx1 |
YES, FRONT TIRE IS NEW, IT STILL HAS THE LITTLE RUBBER NIPPLES STICKING OUT OF IT. DONT KNOW IF IT MAKES A DIFFERENCE BUT THE BIKE SAT FOR A YEAR IN A GARAGE ON CONCRETE, NOT ON A STAND WILL A DAMPER TAKE ALL THAT AWAY. IT IS NOT A TANK SLAPPER AT ALL, BUT IF I WOULD STAY ON THE GAS IM SURE IT WOULD GET INTO ONE, AT OVER 100 MPH THATS SCARY | ||
| Natexlh1000 |
You don't need a damper. You need to set up the suspension for your weight. Perhaps the guy before you set it up wrong even for him! I think the thing to do here is to set the bike up for factory default settings before you buy anything. Do you have the manual? | ||
| Ratbuell |
I second Natexlh's opinion - set up the suspension properly, you'll be amazed at the response and handing of the bike. Second - TURN OFF CAPS LOCK. You'll be amazed at the response and handling of your topics when you aren't yelling at the other badwebbers  Third - are you pulling the front wheel up? I notice on my S1W when I'm hard on it in lower gears, and the front end unloads, it was easier for any shoulder input (clutch grab, brake cover, throttle change) to induce a steering shake. I did add a stabilizer (for other reasons - primarily off-ramps at 75) and it took care that too. | ||

Just had mine dyno'd yesterday. 2000 X1 V&H muffler, race ecm and forcewinder. 86.98 HP and 72.12 lbs. ft. of torque. I don't know if it is good, bad or average. Let us know what you got on the dyno. | ||
| Limitedx1 |
the bike night was rained out, but i am going to cranberry for another one tonight. they may have one they may not. sorry for the caps lock, i am a CAD drafter and pretty much always have it on. i tightened my head tube bearings last night, but didnt get to test at high speed, my front forks look to me like they are set at factory specs. the two marks line up. i read through my manual and it doesnt have any weight information to go by. so if anyone has a good setup that works for a really light person feel free to share. | ||

had mine on a dyno in april. 82 rwhp and 74 lbs. of torque. race ecm, stock header with v&h muffler and rizoma air filter. Was a little dissapointed, but I guess that is about average. Tire may still have nipples and be bad, could have belt seperated or maybe have been bounced off a curb. Had the same problem with a brand new tire and FINALLY got the shop to replace it. Having the same problem on my suzuki, just to cheap to buy a tire right mow (Message edited by tom_b on June 14, 2007) | ||

Those are all pretty normal numbers, here's my run from way back in 2002. This is with a gutted Airbox (K&N filter) and a white brothers pipe (85 HP/75 Torque) Dyno Run | ||

I had head shake and tried everything from new front tire through steering damper and suspension settings. I finally considered my bug screen was acting like a rudder in high winds approaching 100. I put on a fairing mounted to the steering head rather than my handle bars and the shake went away. | ||

I think if you do a search on here, or on sporttwin forums, there's a chart for suspension setup. I thought there was one in the owners manual...I know there is in the XB manuals, as I just set up a Uly for a customer the other day. I know I have it in both my S1W and my 95 S2 manuals...but I think the forks are different from those bikes to your X1. | ||

"MY TIRE IS BRAND NEW IN THE FRONT..." When I put a new Dunlop 207 on the front of my M2, the bike would headshake on hard acceleration and if I took my hands off the bars. This also happened to buddy who has a Hayabusa, but the symptoms started to aleviate for both of us once the tire started to wear in. Not saying you shouldn't check everything out, though... | ||

LTD did the head bearings feel loose ? | ||
| Bad_karma |
Ronald There is a break away/force spec for tightening the head bearings. I don't recommended over tightening. Joe | ||
| Blake |
On an X1 you'll need to do it right and set the suspension sag per your manual. It's easy; just follow the instructions in your manual. | ||
| Tom_b |
ron, got your pm about polishing. start with 400 grit for stripping, then use 600 grit and then 1000 for final. once done sanding use aluminum polish to give it a nice shine |
