Had one on my small tire Kawasaki dragbike for years. I found out how well it works one day when I raised my head up from behind the fairing just as I crossed the traps on a 1/4 pass. At 145mph, the wind turned my helmet around on my head and I was temporarily in total darkness. Not cool at all. Took all the composure I had to maintain a straight line with one hand as,I pulled my helmet back in place with the other. Streamlining makes a difference along with a tight helmet strap and a properly fitted helmet.

I think I bought mine from Chaparral about 20 years ago. They still stock the with windshield for around $60.

Billy,

Go big or go home right

How about an Assassin style road race full fairing...

That's how to ride a bike!!

Sure is, Russ Collins before he became "famous". 1971 or 1972, single engine, Ralph Muldoon aluminum dragster chassis. Pepco blower, nitro methane injected.

Good stuff.

It must be old videos somewhere with the sound of those hot CB750's?

That flaming photo would fit a bottle/jar with hot chili. Trinidad Scorpion, Bhut Jolokia (Ghost pepper) or similar tasty stuff!

Saw a Muldoon frame drag bike on a dyno last week.

Hopefully he gets down to Valdosta. He's an older fella getting back into racing. Super nice guy. It should fly pretty good......maybe 9's with some practice or a seasoned rider. I'll have to go up to New Hampshire and see it run.

Here's some excellent hi performance duct tape! Lol, Bill

Hey Bill, thanks for coming to the meeting yesterday. We at least got Mike to consider reducing the number of races. Not sure what else productive was accomplished. Nevertheless, we'll make as many as possible.

And I appreciate you bringing the valve cover. It'll probably be my only piece of bling on the engine, thanks to you.

Well, not sure who made it yet, Kosman looking kinda, I know I like it, the work looks professional. Looks promising. Gotta get busy, Bill

Bill/BentON Racing · « **Reply #792 on:** January 31, 2017, 08:56:37 PM »

Here you go. Single digit bike, Yippee Kai Yeah! Lol, I'm a certified Honda 750 nut!

Something tells me we'll see a single digit Honda going down the track in 2017.

Pretty sure you are correct!

And.....it won't require a blower or N2O!!!!!

Great to know someone is shooting for the nine second zone, N/A. My pockets are shallow and resources limited for that type package so I won't be attempting that particular record. I'm sticking with a poor man's method of making power. 😁

I wish mine had lasted this long! Lol

Bill/BentON Racing · « **Reply #797 on:** July 02, 2017, 07:35:09 AM »

Well, after 6 weeks, I can finally wrench again. So back at it, got to get ready for Galot, 1/8 mile! Gotta rebuild F brake m/cylinder and maybe caliper also. Oil pump needs Elan's kit also. Check fuel delivery and time to crank Patches again!

Jerry Rxman Griffin aka MuthaF'er · « **Reply #798 on:** July 02, 2017, 08:31:43 AM »

Great news Bill. Get at it

dragracer · « **Reply #799 on:** July 02, 2017, 08:53:50 AM »

Sounds good Bill. I know you've been anxious to get the bike repairs done so you could do some testing. The Galot race is approaching fast for us. Take care of the hand.
