I have the bars on and the front end strapped....and it works. It has been said that living in my area you can Drag Race everyday but Monday if your willing to travel and that is true. I made it to the track for some test runs. Let me start by saying I'm no pro on a bike nor in car however I have a lot more experience in the car and zero on the bike. I am rusty for sure! I made 10 passes on the bike and honestly could have made more, I was hot in my leathers. I went to the track solo so I have no pics but I do have a stack of time slips. The numbers and some info. 1st pass, 2nd slowest of the night. Front end strapped a little to tight for my liking. Left at 6k or close. With no one watching I could not tell what the bike was doing so I just had fun! Stock street tire pressure. 60' 1.795 330 4.684 1/8 7.082 MPH 100.94 1000 9.186 1/4 11.001 MPH 124.81 Best pass of the night. Loosened strap, air the tire down some, launched at 8K. 60' 1.689 330 4.544 1/8 6.902 MPH 102.60 1000 8.941 1/4 10.716 MPH 122.22 Best 1/8 MPH 105.55 1/4 10.718 MPH 125.79 Best 60' and MPH 60' 1.676 1/4 10.777 MPH 133.09 The numbers tell me I left A LOT on the track. Between hitting the limiter more times than not and clutch shifting tells me I need to get the air shifter installed! My best MPH tells me I should be a hi 9. I definitely need to leave harder. I can't tell if I'm spinning or riding the clutch. I'll take my buddy John with me to help me get a idea what is going on. | ||

those are good 60's. Your foot shifting is the factor killing your ets | ||
| Bott |
before I went to a shifter, I was just toeing up on the lever...as soon as the limiter hits it snicks right up a gear. Just dont forget to unload lever between shifts,like i often did  | ||
| Puzzled |
LOL, my foot shifting is not as quick as I think I am! Getting old sucks. I'll work on mounting the air shifter tomorrow.  | ||

Where did you get the bars? Make them? I see Pingel has them for the XBs, seems they could be made to work. I would also say you are on the clutch too long...ya got bars-let 'er eat! I am new as of last September,but am cutting 1.8 60s at stock wheelbase. I believe Littlebutquick was in the 1.6 at swb....lol these things are not exactly 'user friendly' at the strip,until you have lots of passes. hope to run bars on mine next year. 10.8s best this year thus far | ||

Made it to the track again on Friday. The humidity was hi to say the least. It is tough burning water over air! I did not best my ET however I was very close to my PB and my MPH picked up. I'm still foot shifting and still grabbing the clutch running down the track, hard habit to break. I ran my buddy on a 06 GSXR 1000 11 times! I'm 10-1. We both were launching at 8k plus. If I hesitated at all he was all over me with that 1000. He regularly "treed" me on the Pro tree but I'd make it up within 60' and hold the lead from there on out. Needless to say we had a blast as there was hardly anyone at the track so it was like a $25 private track rental. Best run of the night. RT .247 60' 1.722 330 4.572 1/8 6.921 MPH 104.270 1000 8.964 1/4 10.726 MPH 127.220 Best of the night. 60' 1.689 1/8 6.921 MPH 128.550 | ||

Didn't get to the air shifter over the weekend.  I went riding instead.  The bike goes in tomorrow for the clutch cover leak so that will shoot my attempt at progress in the butt for this week. I'm going to try and work on th side panels for the bars as well as a cross member for them. Speaking to someone who knows a little about bars he was telling me to get them cross braced. The X does little for vertical stifness. | ||
| Fast1075 |
If properly mounted the side panels add an amazing amount of stiffness in the vertical plane...actually the stress in on the top bar beacuse it is in compression when loaded...the bottom bar is in tension.. the worst flex (side deflection) is controlled by the X brace on the top of the bar set. | ||

I worked on the bike a little last night. I spent some time mounting the piston for the air shifter. Currently there isn't an off the shelf mounting kit for these bikes. What I came up with I feel should work just fine, we'll see. I made a paper template first than transfered it over to my piece of 1/2" aluminum. If I had something thinner here I probably would have used that instead as 1/2" is overkill.  | ||
| Puzzled |
Next up was cutting the aluminum. I started with my horizontal band saw just to get a smaller work piece.   | ||
| Puzzled |
I used a metal skill saw to make the rest of the cuts. (This saw kicks ass!)  | ||
| Puzzled |
Next up was fitting the piston to the shifter arm. The arm is slightly wider than the clevis opening. I quick trip to the table sander knocked the finish off of the shifter and allowed the clevis to slide over.  | ||
| Puzzled |
The bolt hole through the shifter arm had to be opened up slightly to allow the pin to pass through the clevis.  | ||
| Puzzled |
The assembly ready to go back on the bike.  | ||

A quick mock up shows where I need to trim my bracket some, more for aesthetics than anything else. I'm going to machine a small pocket in the bracket for the piston to sit in. This will help with the angle at which the piston sits. I gave a little pull on the shifter arm to pull it away from the bike to also help with alignment. The range of motion feels smooth.  | ||

I finished the air piston bracket this afternoon. Overall I'm happy with it. When I make a batch of them I'm going to make a couple of small changes to the design. I machined a couple of pockets for the bolts to sit in. This keeps the heads from sticking out to far. Just for grins I ran a bit around the edge of the bracket just so it didn't look like a simple flat piece of bar stock. I also machined a pocket for the air piston to sit in. I would enlarge this area a little on the next one. The piston mount via drilled and tapped hole. I went with a 1/4"x28 fine thread to get as many threads as possible in the aluminum.  | ||

Here is a view of the air shifter from the seat. Despite the way it looks it does not protrude out enough to bother your foot. Than again it unbolts in about a minute so removal would not be tough either.  | ||
| Puzzled |
Next up was the mounting of the air bottle. I choose to mount it on the wheelie bars as opposed to the bike. This way when I remove the bars the air goes with it. I may want to rethink that! The bottle bracket will get clamped to the wheelie bar support bracket.  | ||
| Puzzled |
I notched the bottle bracket to fit around the support bracket. The notch doesn't allow the bottle bracket to twist.  | ||
| Puzzled |
Here is the clamp with recessed bolts. With the bolts recessed they won't hit my side panels I made for the wheelie bars.  | ||

Another Friday night at the drag strip. I made 14 passes tonight even though the track was a little busier than my previous two visits. The crew at Island has been taking care of us bike guys. Best run of the night. RT .138 60' 1.683 330 4.462 1/8 6.725 MPH 108.32 1000' 8.693 1/4 10.381 MPH 132.63 Best of the night. 60' 1.676 1/8 MPH 108.660 1/4 MPH 132.910 | ||

It appears that you aren't puzzled at all. | ||

One of the two blunders of the night. I staged the bike at around 9k and I must have given it more throttle to hit 10.5K and the air shifter hit placing the bike in second, the light changed and I left in second. I didn't have my foot on the shifter so there was no way I could have shifted back into 1st. Oh well a 9k launch in 2nd gear. The 60' was horrible but the overall mph was decent.  | ||
| Puzzled |
Tale of the tape or time slips... I'm still leaving slow, whether I'm riding the clutch or ?, I need to drop my 60' times. Later in the evening I did experience some tire spin off of the line even with a good burnout. Now granted I'm running on a Dunlop GP Sportmax. The tire is toast for sure. I may beat on it one more night at the track just to be sure there isn't anything usable left. I found on a couple of runs I was not at wide open throttle. In an upright position when I grab the throttle and twist as far as my wrist/arm will go, I have more throttle left. I do recall seeing guys with their elbows way forward grabbing the throttle. Doing this same motion nets me a WOT. So I have to change my technique, hard to get use to but do-able. Launch/seating position. I'm still flat footing the bike to insure I leave square on the bars. This has me sitting upright more so than leaning forward over the "tank". I need to work on this coupled with my throttle arm. I'm shifting my body on launch as opposed to "setting" my body where I want it first. Helmet. The Joe Rocket I'm wearing is an OK helmet but not ideal for what I'm doing. Strapped tight it is pushing down obstructing my view when I'm a full tuck. Street wise it is just fine. It could some more padding to hold it tighter/in place. My Shoei bounced off the pavement (another one) so I need to order a new helmet. The fogging was horrible the last 3-4 runs. I could use my Pin-lock system when I get another Shoei or I have considered a Scorpion for the track as their shields are fantastic. All in all I'm getting it. I have some work to do with learning how to set the wheelie bars and front end strap. I even was goofing around with the engine kill time with the air shifter. I suppose I could just keep trying different variations or hit a few race days or forums and ask some questions. | ||

where are the bars from? Pingel bars for an XB? Also, our machines have quite a long twist to WOT. I bought an R1 tube for mine,which is supposed to fit perfect and is a 1/4 turn to full throttle. As my bike has been in the shop since early June with a blown top end waiting for a replacement motor,I havent installed it yet. | ||
| Bott |
Another question. Where and how did you mount the shifter's solenoid? Do you always run with the front strapped so 'high'? I wonder if all that travel up front might be causing pogoing in the rear as weight transfers. Need FastEd to chime in here. | ||
| Puzzled |
Yes the 1125's need a BIG handful of throttle to hit WOT.  The bottom mark is full closed. The middle mark is where I rotate the throttle to when seated in my natural position. The third mark is WOT. I will have to work on my hand position to insure I grab all the throttle the 1125 has to offer. The bars are from Pingel. It is something I have been working on with Randy. A handful of changes needed to be made to the XB bars to make them 1125R friendly. I have yet to test them on a CR. The air solenoid is mounted under the seat. I'm running air/electric. My Dynatec Shift Minder combined with Pingel Electronic Kill Module make the shifter a buttonless set up. When the bike sees the pre set number it shifts. Next up is some sort of two stage or similar. I agree the strap is off/wrong. I loosened the strap as I didn't like not having the front wheel on the ground at mid track and I believe loosening the strap made it worse. I'll pull the strap tight my trip out. I'm not experiencing any pogoing. My only gripe is having no bar input. (Message edited by puzzled on August 03, 2010) |
