Try putting 10# of weight on the front axle - when I did that on my Gen 1, I picked up 2 tenths, no s**t. I just used 5# lead ballast weights from Quarter-max and a piece of all-thread mounted in hex spacers through the front axle (use nyloc nuts). I ran 16/44 gearing, left at 10K rpm, and ran 9.20s all day long with a 6" stretch, lowered 3.5", a C02 shifter and a 180# suited rider weight. That was done with a 163 rear wheel HP bone-stock engine. PS: Pulling the air filter was worth 2.5 MPH. All with a stock ECU, shifting at 12K rpm, & a 180/55 - 17 Shinko hookup tire. I just bought a Gen 4 and am setting it up much the same way. Hoping for 8.80s with 25 HP and 2K rpm more!

Almost forgot - best times and MPH were all run with Shell 87 octane pump gas (No ethanol). You could FEEL the difference between that fuel and the 92 octane I ran for a long time.

I see it's been a while since this thread has been used, but, i'm curious what other Gen3 guys are using for 1/4 drag racing?
i'm currently at -1/+4 and seem to be stuck at 144-145 mph. I'm clicking 6th gear right at the stripe or just a shade before. I'd like to click 6th at about 1000-1200 ft down the track.

I raced a guy this weekend with a gen 4 with 46 rear sprocket, i think he had a 16t front, and he was running about 2-3 tenths quicker and 5mph faster.

i'm still struggling with getting the bike to launch without pulling the front end. Part of this was due to not having the launch master release at the right time, so I was on the low rpm with clutch in and when the clutch would engage to launch, the 2step was off. so basically launching somewhere around 8-10k. I'm not talented enough to slide the clutch and make that work for me.

my 04 was geared 16/44 with same extensions ur running, crossed the line tight in 6th right at 13200 tach indicated at 157, would hit rev limiter just past it. 07 is 67.5 inches with 15/43 crosses the line indicating 14k on tach with reflashed ecu at 160. if u can manage it gear to max out in 6th, probably a couple of more teeth on ur 08 for dragracing. 04 and 07 both tachs read 700 rpm high, dyno verified.

i'm going to add another tooth to the rear and make it 16/46. Anybody using a 15t front on a gen3? I heard there might be clearance issues as the sprocket is quite small.

any idea what your 60's were on your 07, what were your et's, what was your launch rpm?

launching low at 6500 due to abrupt clutch. last pass run was 1.42 60', 5.50/132.34 and 8.53/160.44 finishing the 1/4. rider 170 suited. key is throttle pinned during launch even if u have to drop rpm's back to do so.

My clutch seems to be either on or off. Guess I need to turn the go pro to my left hand and see what i'm actually doing. Also, looking at your 60, maybe I should turn my 2-step up a bit. I'm launching at 4500 while holding wide open throttle.

4500 is to low... your lowered and stretch... try launching at 8k with the throttle lock and clutch out before you cross the tree... should see that 60 drop for you.

i'm having a hard enough time keeping the front down as it is. Next season, the bike should be fitted with a 10-14 swingarm and maybe i'll soften up the rear preload a bit, to get a bit more sag.

actually extending that swingarm to close to 70' will overleverage the stk ten shock, good cheap option is busa shock, got one i will donate to u for shipping. 60's and et will fall with that setup. good seat to lock u in place will raise confidence level to leave higher/harder. arm, shock and seat probably ur best options to go quite a bit faster. all u lack to run fast and consistient is chassis/clutch work.

I'd be more than happy to take that shock off your hands. Send me a message with your paypal details and i'll send some $$ your way for shipping and your generosity.
Any recommendations on a seat? I've thought about buying a tore up one on ebay and having it redone with thing foam with a back step, or, going with a composite one. Either way, i think it'd be about $100.

Hey bud this is Anthony on the gen4 u raced at woodburn. I'll tell u want man I found some really cool trick to get faster. Still rocking 16 46 sprockets and it's perfect. Mid 6th gear and 151mph traps at 210lbs. I also picked up another "get this" 4-5mph l shot u not. All I did was gut the stock intake tube and paired it to the mwr full race filter. I swear that filter added 8-10whp. I know it doesn't make sense but it worked. And I'm installing autotune this week hopefully to see where I'm at with afr so I can dial it perfect. Still rockimg u4.4 gas as well. Going out next Sunday to shoot for that elusive 8.9 run. Still hovering in the 9.3-9.4 area. Gonna get crazy on my launch this time. Was at 8-9k but now I'm gonna hit it at 10-11k. The 1.58-1.63s just aren't cutting it. Lol. Hit me up brotha.

Are you running this filter?

4-5mph is something that I wanna get too lol. Was your 151 traps with that new filter and on u4.4? Any other info on your bike?

I was able to run some 8.8's and 8.9's a few weekends ago in good cold MN October air trapping high 152 to low 153 on pump gas. I'm about 200lbs suited and felt like I was hitting the limiter on the -1/+7 sprockets so went to -1/+6 and seemed to do a bit better.

The bike is a simple setup. Extensions maxed out with 16 46 525 sprockets. Graves/cat delete, mwr Sbk "$280", filter and worth every penny. It's the inverted design that works so well. Helps all cylinders get maximum even flow, gutted intake tube and lowered about an 2 inches. I also modded the stock seat down as well as lowered the foot pegs. Gonna install bazzaz/autotune in next day or two and tune for mr12 for last race of year this Sunday. Been running u4.4 on just a flash. But we race at 2700ft at firebird raceway. So bikes rich no doubt and why the intake mods helped so much probably leaning it out some. We will see soon how much the afr tune and mr12 help.

i run no air filter when at the strip, like driver i gutted ram air tubes. i'm tuned that way on oxy fuel.
I thought about running no air filter at the track but just get too nervous to do it. Do you usually pick up much by running no filter vs say a bmc race or equivalent?

Sounds like a pretty sweet setup! If you don't mind sharing, what'd you run and trap before the filter/gutted intake and what'd you run after?

I have my stock intake gutted too and can see how that filter could make a difference. Back when I worked at a car shop, my boss picked up 25hp on his dsm just by changing out his small, shitty, old air filter for a new and much bigger filter.

Hey Anthony-
just saw your posts. I'm running a BMC race filter, took the added parts out of the airbox (pre-filter screen thing). Not sure how much gutting of the intake I can do. Aside from the air inlet wrapping around the frame, it's pretty much a straight shot into the airbox. My box doesn't have actual "ram tubes" like the old ZX9's.

I now have a 15/46 setup, also my gen 3 will be getting a Thompson 10-14 swingarm and slammerz fork cartridges and a busa rear shock.

I'm sure some u4.4 will find it's way in my tank as well.

With the current tune i'm running, even with the u4.4, my afr stayed consistent at 13.5:1

Hell ya that's gonna pull hard. Should be top of 6th. Have u had it on the dyno yet? I can't wait to get the auto tune on there this week and dial the afr in on mr12 for Sunday's last race. I'd really like to hit 8.9 on last day of year or atleast better my [email protected] We shall see soon enough. Is ur season over there as well?
