Riding a long bike is harder than I thought it would be. I made it out to the track yesterday. Since my sig times I have added 6" to my swingarm and changed the gearing to 16/41 and added an airshifter. I thought that it would be a breeze to launch, but after getting so used to draging the clutch almost all the way through first it was a hard habbit to kick. I only got to make six passes yesterday, and half of them I blew the tire off because I was running too much pressure. I finally ended up running about 17psi in my power race soft. So on the 3 full passes I made my best looked like this.
1.487
3.879
5.888 @ 122.65mph
7.638
9.151 @ 148.73
I will say that the da was +1600 and rising as I was making my passes, and my previous best was on a -500 or so day. But still I wasnt very happy with my performance. And to make things even worst there was a guy close to my weight, he was 197 to my 205 unsuited, on a new busa with a full brocks setup, slammed, but still stock arm and he was ripping off 9.4's at 153-155mph all day long. I couldnt believe the mph! He said he was still running pump gas! And I believed him since the pipe had a dark brown tinge to it. And I know that when I used to run race gas it would white tip the end of the can. He told me that his best run ever was a 9.23 and I told him that I had gone 9.28 @ 151mph at stock length, which I dont think he believed since I was now running a long arm and bearly beating those same times. But oh well, it is like learning how to drag race all over again. Ill just need to get used to it. I remember the first time I took the 14 to the track I was happy to run a 9.5x and then over the next couple of months I got it down to a 9.2x. So I just have to put in some more time. Im hoping to eventually run a 8.99999 on motor but I dont know if Ill be able to do it with the warmer weather coming in.
What are you heavy guys running for gearing? Im pretty sure I need more gear. If I tried to get off the clutch fast it would just bog and have to recover. And then I would have to shift into fifth just before the finish line. So Maybe go up 2-3 on the rear? Id like to be able to get off the clutch quickly and not have the bike bog down. I also think It might be time for a new clutch, Ive got over 140 passes on it now and over the last few times to the track it seems that I loose mph with every pass. By the end of yesterday I was only trapping 147.0 mph. And in the beggining of the day I had gone 149.8mph.
I also thought it was crazy when the busa guy told me that he had to change his clutch every 15 or so passes! wow crazy. I usually make more runs than that in one day.
What are you guys 60' with extended bikes? I was able to pull 1.50 on the stock arm so I thought that I would be able to get into the 1.3xs now. Is that possible?

16/41 is what i use .... My 60s range from 1.34 to 1.40 Because i keep switching back and forth from my long bike to my short bike .. If i stay on my long bike 1.37 are Avg .. You just need more seat time and the 60s will drop ....Don't worry about them new busas , they do MPH killer but the 60 footers are allways lacking what a ZX14 can do ...The clutch on the Busa is just not as user friendly as a zx14 for most folks ..MPH on our zx14 is a little low, make sure you shift at 11,200 ( on the tac ) Just before the rev limiter .. Tuck in as tight as you can , feet on pegs ,elbows in tight ..
I told you 17 PSI ..... LOL ____________

I am currently running 16/45. Like I said, you lose about a tooth of gear due to the tall Michelin.
My best 60 ft. is a 1.49 at 230 lbs. suited. That was +6", 16/45, and an Ultra Soft Shinko. I am by no means a fast guy. I'm sure you'll see your goal soon.

A few weeks back my bike ran 9.17 @ 153mph and I weigh 210. The Busa guy aint spraying.
Racer, a good indicator of losing your clutch is drop in mph per pass.
I might add that was 16/44 gears with Schnitz heavy springs and a bad 60ft of like 1.53. Just changed to 16/42 because with the heavy springs right off the line(huge wheelies), cant seem to slip the clutch good enough for 16/44 and I have a 30 shot to use this season. 16/44 had it needing a shift 50 ft from the finish on the button.

IM not sayin they cant run that mph, but the difference shouldnt be that much. Also he said 1 was stock length. 155 stock length is rollin 4 sure.

I geuss your sayin the brock pipe made him slower, seeing how he has 1 on his 14?
Im not followin. Or is it that the busas run with brock pipes?
posted February 01, 2009 06:25 PM
I dont think so Wheelie, but cant rule that out. The one thing I forgot in reading his post was 17 psi in the tire. We all know that lower pressure kills mph. I run the Shinko at 20-24 psi. It was at 22 when it ran 153.
His 1/8th mile performance should have netted him a 8.9-9.0 pass at 151+mph. Racers if you have the stock springs in the clutch pull the clutches and check out the center steels.
Personally, I am going back to the stock springs and installing a CycleLogic lockup.

I don't think so ..He said he was riding it like it was still stock wheel base , sliding the clutch to far ..His 330 times are off , once he gets a handle on this his MPH will go up ..I had the same problem with mine changing from stock wheel base to 62 inches ..... For a short time after going to 62 inches i only ran 5.90s @ 122 very close to what i did at stock wheel base... Seat time and bang 5.70s @ 125 , more seat time and 5.60s @ 126 to 128 ...

Guys i have been as fast as 158 on my zx14 , that is if i put my feet back on the pegs ... I don't put them back up because it hurts my left leg to much ..But dragging them cost me 3 to 4 MPH .. Doesn't seem to cost me any ET so i really don't care about the MPH loss ..
The Video shows what i'm talking about..

Come on now Smokin, the man weighs 205lbs and is 6inches over. We all dont have the natural lightweight build that these bikes perform better with like some people we know .
