Well it’s always been on my list to hit 200 MPH! I have built my baby pretty much to the Brock specs to do just that. I just signed up for the top speed even in Loring Main LTR for a 1.5 miles ass clincher! I was in the middle of a valve adjustment and I was thinking man if I get there and go 195 I’m going to be pissed! SO……I decided to drop my baby off to Jim at Competition CNC to have some work done talked to them for a long time on reliability because my main concern. I ride 10k a year and will be in way out there places with nothing. So I told him I’d rather have less power and more reliability but he assured me that it will not change. What he’s doing with the Super Sport head is just improving the Kawasaki head to flow better. That doesn’t affect reliability. He will be milling the head slightly which will give me slightly more compression but nothing crazy. He explained to me that he has many of them out there and I would be fine. He is going to put adjustable cam gears in there and degree the cams which he says show a very nice improvement for sure. The he’s adding 47mm throttle bodies which should be real nice. The bike comes with 44mm. That should be worth about 6HP or slightly more. This set up should be good for 208 to 201HP at the wheel. Once he’s done with the build we’ll install the re flashed ECU from Dynotronics and then head to Dyno Time in Brookfield CT for a full custom map! Man I always seem to get myself into these situations…..I was just doing a simple valve adjustment! Lol but one I was in there I couldn’t see any reason not to make some small changes…O Boy should be a great riding season….:crazyloco

200 mph club

I have several friends that race out the salt flats here in UT. They come every year and race at the BUBS land speed races. 2 of them are in the 200 mph club already and i had them build the motor on my v-twin bike. I have only hit 185 mph with a speedo healer. I would love to hit 200 mph! be safe dude!!!

Just curious.
What's the fastest you've ever been?
And why wouldn't you at least try for 200 first before doing more work?
Me? I would like to try to get 200 out of what I had to work with instead of going into the motor. If i hit 195, I would sit back and see if I should remove the mirrors, different windscreen, tire pressure, tuck position,etc.
Seems anyone can build or put money into a motor and get to 200. There isn't much of a challenge anymore. And if you still didn't hit 200, I bet you would be even more pissed when it could have been something simple.

185 I've always wanted to hit the 200....I've been 185MPH with the healer on and the GPS. It was a great feeling for sure! But I actully don't like going the huge numbers on the public streets. Much more than 150 is getting a little fast on the street. But if I'm going to be riding 9 hours 670 miles to an airstrip some where in Maine I'm going to make sure I make my dream happen! :crazyloco:scared:crazyloco

185 the challange is can I make the number cuz.... I know my girl can easily mak it......

Only want to do this once!!!!! Aaaaa I think~ LOL

Looking at what you've done to your bike, I think you could do 200 mph. But I could see where you would want that extra edge to hit your mark.
I also didn't realize it was that far of a ride to get there.
I've only been (only?) 145mph and it's enough for me. i can't imagine 185 or even 200mph.
Good luck and be safe

Just my 2 cents, but you might want to check out the tracks safety requirements before you head up . Different tracks have different requirements and it would suck to go and not be able to run . If you checked it out already just ignore me . Have fun be safe and take pictures. We all need to see your 200 mph slip

:roflI done 160 on this one.I know it's accurate.Set with speedohealer and GPS.I'm going for 175 this year as I never done it.I'm taking the 43 sprocket off and going back to the stock 41.I have the 16 front which isn't stock.I have a taller tire in the rear which could help.Then I'll get my wifes GPS and set it up again.I should hit 175 then.After a dyno tune I should find some more topend HP.

OP where do you cruise in CT? I'm in the Hartford area. Have you ever been on route 8 up near Torrington and Windstead? I've put some pretty serious number up on that road.

I remember reading some long posts on what it took to reach 200 with a stock motor.
1. The mirrors have to go.
2. The OEM windscreen is the one to use.
3. It will help to lower the bike if strapping the front is legal.
4. High tire pressures.
5. Ceramic Wheel Bearings are a must if you didn't install them already with your BSTs.
5. Freshly cleaned and lubed chain.
6. Run some injector cleaner through the tank before you leave.
7. If you can find Sunoco 100 octane unleaded, use it.
8. Some racers use the zero weight synthetic oil.
9. You are going to have to change the gearing. The countershaft needs to be a plus one. you can find out the best gearing by calling Brock's performance. For this max attempt, the bike will be sluggish accelerating with this new higher gearing. Keep your current setup for reinstall after the speed attempt. So buy a new 520 kit.
Rather than mod the motor, just have the cams degreed and the valves adjusted correctly. Maybe a slightly thinner head gasket?
10. You must already have a proper fitting one piece suit to wear. You wouldn't want it loose and flapping at high speeds slowing you down.
11. Waiting for a tailwind wouldn't hurt either. Will they time you in both directions?

You already knew this stuff.
good luck with it.

I ride all over the place everyday I can but I'm from Orange. I ride to Hartford and Enfield a few times a week for work. Route 8 is a real good place for sure I've been 180 there but always worry about something coming out in front of me. That's why this Maine event will be awesom for sure! it's 600 yard wide....The way my bike is set up I should hit 200 for sure. (I Hope) But there is nothing else I can do short of a 30 shot of NOS. LOL The only other thing I'm going to do is put on a non o ring chain just before the even for less friction. :scared

Awesome to hear you are going to Loring. It is a nice track to run at. I went there last year and got a record with my 14 at 221mph. This year bumping it up to 235 but won't be making the 42 hour drive there this year. Going to mojave magnum instead.

What gearing do you plan on running?

I see you have the bonneville pro... have you shaved the nut?

How is your tuck?

What tire pressure you plan to run?

Have a metal strap over the battery?

Triple check the rules for what is required on the bike because they will check it 3 times.

The most important thing is to.... HAVE FUN! :crazyloco

This will give you a couple Hp up top I agree.
You can buy a chain from Kraus/Sidewinder racing called the smart chain II It's an O-ring chain with a 16000 lb. rating and has a patented design to reduce the effective friction at the O-rings to almost zero. call them up and talk to them. The chain is going to run you about $200.00. Dough isn't a problem for you. Might as well pick up the titanium sprockets while you're at it. Your new drivetrain should cost you aroun $450.00 with a couple cans of their chain lube and an extra master link. The chain guide tool would be good also. There are some cheesy videos on the site. Call and talk to them.

Also couldn't hurt running 190/55/17 roads 2.I thought mine would do 175 with the 43 sprocket.Think after the dynotune and 41 tooth 185 sounds reasonable.There is this interstate that is 2 smooth miles.Think I'll go down it take the exit.Turn around.Then make my run then get off the next exit and hit the back roads.Hope I don't wheelie too far on the entrance ramp.

Right now I run a 190/55 rear with 17/42. I had the ECU flashed and they uped the RPM's by 500. On the gearing site it shows 17/42 at 11,000 RPM's is is like 205. So now the new Red line will be 11,500 so I think I'll be good there should push her a little higher. But I'm going to bring a 40 ir 41 rear also. If I plug in the 41it brings the top end to 214. But i think with the 42 rear I'll have that much more punch to get there. I just need to get the number. I don'r care (right now) to get much past that! lol
I haven't shaved the nut but with my ECU flash they took off the top end limiter so I should be good there. As for the strap I didn't see anything in the rule book about that. I'm using the stock strap. I do have to take off my rear hugger and install the aluminum or steel chain guard. Tire pressure I thought I rum 38 psi all around and see how that goes. And My tuck well I'm going to squeeze my girl so tight she's going to honk the horn for me to let go! haha I have to install the kill switch they want and they like you said really read eveything. did you install number plates? I was thinking of just putting numbers on my rear seat cover on each side?:headscratch

I'll have to look at this chain for sure. It makes sense cuz I was going to buy a second one just for this run. My DID X ring I bought last year is throwing O rings now so I have to replace that one after only 8,000 miles! Maybe this one will last longer. I have the BST wheels and so far the only sprockets I know that fit are the Vortex? I'll have to look if these might fit.
