top Speed????????

hello again


had the carbs cleaned on my bike awaiting this week end to run fuel lines and hope fully be on the road sunday




my question is just what is the top end on this bike


mine is an 82 turbo seca xj650

 

dont know about the turbo but the non is 122mph.

 

Unless you have brand new tires please don't try to find out!

And read this: http://xjbikes.com/Forums/viewtopic/t=15874.html

What would happen if your rear wheel locked at that speed?

 

then you would be an organ donor.

 

no spit, Sperlock.

 

I would definetely have those brakes in top shape, SS brake lines are a plus (Thanks Chacal). It take a bit to stop once you get it wound up if something were to jump out in front of ya...
Top end is somewhere near 125mph. ¼mile in 12.5secs@ 106 I believe, a bit faster with the power up kit.

 

I hit 160kph the other night (100mph) I don't really have a problem with the speed and have gone faster than that, but I don't think I would on this bike!! it's a cruiser so I think I'll stick to cruising!! and leave the racing to the sport bikes! with the windshield on it's wobbley and with it off I'm a human parachute!!

last week i hit 115MPH on my 82 xj550 all stock except the shaved air box.

 

Errr back up less than 250 into a bike an dyou are winding it up that fast. please say the PO had just put tires on it for ya??

 

I wouldn't bother driving my maxim that fast....
!, Its not a race bike
2, Its not a race
3 Its not made for speed

 

Both my XJs have new tires, new brakes, new shocks and freshly rebuilt forks and I still don't push it to 100. (OK, maybe once or twice a season.) I DO spend a lot of time on the freeway at between 75-85mph though, just keeping up with traffic. You cannot ride that fast, safely, with old components.

Don't ride a 25+ year old bike that fast unless it's been completely gone through. Please.

 

thanks for the input guys gonna get her runniing right and probably sell her 125 just is not fast enough

 

yea the po fixed everything except had no clue on carbs and thats all i fixed!

 

Where exactly do you live that 125mph is not enough? Aside from track riding there is no where that I can possibly think of where you would need more speed. The turbo 650 tops out at 140 I believe. Something close to that. Its higher than 125 though. Hell my bike will do 200mph+. I will never know exactly how fast it will go cause im old enough to know its not a good idea. I sold my last one cause I got clocked at 173 and nearly lost my license. Take it from me...speed is fun but the consequences can be dire. Once you get the turbo running right you will probably keep it. There are faster things out there but the feeling you get from riding a bike under boost is like no other.

 

^ straight out of my riding groups saying.

"Its not about going from 80 to 160 its about going 0 to 80"

 

The Turbo bike is geared exactly the same as regular Seca 650/750 ' s , so to do 140 you'd be deep in the redline. And there's no convenient re-gearing option.

But there have been folks on here saying the engines will spin to twelve grand without blowing up. Sounds like XJ abuse !

 

well heres the thing i dont want to sell her i want to rocket her to the end of a half mile stretch and come out on top and the only way to do that is to be able to beat a 94 katana 600 thats factory i have research going on the kat but i need to know the details of my bike as well so that i have or may have a fighting chance


my bike needs a lot of body work and there fore i have seen the prices and its not cheap so thats another factor

 

sorry seems to be cut off the page

my last post that is i am racing a buddy of mine
he has a 1994 katana 600
and thats why i need to know top end

and also why i probably will sell her


cause if i cant beat that bike then i am

definitely no living in the shadow

does any one know a good place to get spec details
on the katana 600 1994 thanks guys

 

I've had my max to about 125. That's more than fast enough for me.

 

Even if you beat your friend's Katana, he'll just say it was the turbo.
I've read about some tricks- - jimmy the wastegate for 15 pounds of boost, lose the right "muffler" , K&N filter , advance the timing , install a slightly bigger turbo , put the guts of a 900 engine inside the 650 cases, that sort of thing.

But how much money do you want to spend to beat your friend?
