Re: GT750 Drag Bike
Back on page 45, a Dave Derrick T500 build was mentioned. Did that happen?

Re: GT750 Drag Bike
Not yet , are you interested in doing a gt/t500? I gotta believe I could build one under 250lbs with good components.........

Re: GT750 Drag Bike
I am building one now.I started a small thread listed here in "Customs". It is a different approach, and using stock steel wheels and really no effort in trying to make it light, I think it is going to be right at 300# wet. Sorry for the thread hijack.D&D CHASSIS wrote:Not yet , are you interested in doing a gt/t500? I gotta believe I could build one under 250lbs with good components.........

Re: GT750 Drag Bike
Just looking at the bike i can see why it would be quick , lighter , streamlined , all the drivers weight is over the rear wheel and what looks like 40mm Lectrons
the older i get the faster i was

Re: GT750 Drag Bike
curious - just noticed that there isn't a radiator on any of these, so how do you cool the block?

Re: GT750 Drag Bike
For drag racing, the bike only runs for less than 1 minute. The heat doesn't build significantly until the bike is slowing down after the finish line and on the way back to the pits. But even in July at Indy it would not climb over 200F. A radiator with hoses full of water weighs a little over 11 lbs so most of us keep 1/2 gallon in the block for heat transfer but there isn't any reason to circulate it. Just happens too fast to be of any benefit. A few have tried to run w no water what so ever but I've not tried that.

Re: GT750 Drag Bike
Are we going to see an 8 second pass on a GT750 this year? I think so. Just a year or so ago I was hoping to see you get into the 9's for the first time. Now I might have the chance to see the 8's.

Re: GT750 Drag Bike
4 tenths is a lot to shave off...but the idea of an 8 second Buffalo has crossed my mind. Trying to get into the 8s on a stock-frames chassis is a very, very tall order.

Re: GT750 Drag Bike
How much of the stock frame do you have to leave intact to stay in your race class ?

Re: GT750 Drag Bike
Dave,
Pretty much all of the main frame. You can make light modifications for brackets etc. You can change the swingarm but you have to use the stock steering neck (rake angle), same foot peg locations (within 6") and the swingarm needs to use the existing mounting location to bolt up. You can stretch the swingarm though and use struts instead of shocks. The idea is that the "Modified" class is a step up from "Stock" and "Altered" is a step up from Modified. On an Altered frame, you can cut just above the upper front and rear engine mounts and replace with chromoly. Rake angle is allowed to change and a welded back-half is allowed.
Dave and Matt Derrick are one of the best (if not the best) chassis guys for these 2-stroke bikes. They can make Altered frames under 28 lbs complete. As a comparison, the GT main frame weighs 58 lbs without the swingarm or struts. If you want to go fast and I mean really fast,
you want Dave Derrick's number on speed dial to build a chassis and Doug Flannery's for the motor.
