what is going on at the tracks???

[RacingJake]

Hey Mike
I think if the engine or clutch gets heat soak it will be inconsistent by a tenth or two. Also what size jets are you running.

[mike J]

Jake, I still have the DynoJet 138's in the bike. I bought some 145's, 147.5 and some 150 mains from Mikuni. My bike doesn't have a open pipe so I'm not sure where to start.

[RacingJake]

If you bike nose's over or feels like you hit a wall before the finish line then it's running out of fuel. I'd try the 145's since you don't have an open exhaust. Those DJ 138's are just to small for the track.

Went 9.87 @132 off the trailer. Best pass was 9.79 @133. At least it didn't slow down at all. Thats about what it was running in the bad air.

First round I cut a 508 RT and then ran a 9.839 on a 9.84 dial. Second round I hit the button for third gear and it didn't shift. By the time I realized it I was on the Limiter.

Great times, are you running 6.3's in the 1/8 and have you busted out of the 4's in 330ft.

Don't you just hate that when you break out being so close. Once I broke out with a .0023 I guess that's like 1/4 of an inch.

It's not getting any better. I'm in a slump. Broke out again with a 9.847 on a 9.85. He was really slow and I blew past him. Here are the incrementals from a 9.77 pass this past saturday.

Jake, I put in the 145's, I couldn't tell much difference in seat of the pants feel. I'll try to get to the track to see if my mph changes any. Thanks for the advise. Mike J

Last yeay it was how slow the bike was, now its too fast.

Your taking too much. Real em in!!!

[RacingJake]

Just making sure you don't starve your engine at the end of the track. You want it to pull until the valve's float then you know the jetting is right. OK maybe you want to shift before they float but you get my idea 8O

Also maybe pull the plug on your exhaust and see how she runs ??

[mike J]

We got rained out again, so I didn't get to see if the jets helped. Probably will be two weeks before I can get back to test, bummer. Mike J

Out making my license runs this week. 4 1/8 mile and 2 full passes. New personal best 9.73 @ 133. 3100 feet DA. This thing should fly in the fall.

I also found a problem with the air valve on my air clutch. It was causing the clutch to come out really slow. No wonder I can't cut a light. We'll see what happens saturday.

[RacingJake]

Way to go Ryan!!

I also found a problem with the air valve on my air clutch. It was causing the clutch to come out really slow.

I actually have a adjustable needle valve on the exhaust side of the air clutch valve to adjust the release rate. It seems like there is always this fine line between wanting it to lock and how much power is available. Hope you get yours worked out.

Good going on that new record!!!!

[lecroy]

Was playing with the old GS on Friday and a guy on a snowmobile next to me that went through the traps at 150MPH. I thought that was really something, until Saturday when one ran the 1/4 in 7 something. It was a new track record, but he could not back it up.

[scotty]

is this with or without snow?????

[lecroy]

I assume your question was real being from Florida. You are right, they are made for the snow but they run them in the bike class on the same asphalt track. They remove the skies, track and sliders. They use something like in-line skates in the front. The track is sort of like a slick. No real tread. The sliders are then all rollers. They normally have a cooler and small pump to drain the water from the block at cool the engine between runs.

The sled that made the 7 second charge was a four stroke with a turbo charger. Sorry, no pictures this time.
