how fast does yours go?

hi there im riding my missis 1986 700 maxim, air cooled,at mo,as shes not using, it, i opened the throttle right up, but could only get 67 mph, how fast should it go,

 

A lot more than 67, my 750 does allmost 80 in 2nd gear, maxes out at about 120.

 

hmmm 750 will be faster,anyway,? she shakes,if i try for 70 mph,

 

You have some significant performance problems.
You should hit 70 in 3rd I would think.
I have an X (liquid cooled version with 5 valve head)
The X has a few more HP.
The X supposedly maxs out at 137mph but I'm too old to test that limit.
I have a friend with the 700 aircooled and it will easily break 105.
My X feels unstable over 115 but where can you go that fast over here anyway. It probably has to do with the windshield attached to the handlebars?

Will it red-line in 2nd or 3rd?
Sounds like you need to read all the carb-cleaning and tuning posts on this forum...and then enjoy the ride.

I just found an article with test specs
Granted this was probably tuned out perfectly but this is how it tested.
0-60 mph in 3.7 sec
12.43 second quarter mile @ 106 mph
It should do 81mph in 3rd
101 in 4th
and 116 mph in 5th (redlined)

 

I got my 85 XJ700 (air cooled) up to 100mph. I still had a little bit more left before it would redline but had to slow down. I was supprised on how well it handeled and that speed.

 

done the carbs, and cables,wooopppeee 115mph, but i prefer my 1200 bandit, she can have her xj, still need parts for hers?

 

whoever thinks the maxim x 700 watercooled compared to the air cooled 700n is more horsepower your wrong both bikes have the SAME HP!!! both have 86hp only diff is the x has 4.4 ft pounds of torque more!! matter and fact the air cooled one beats the x up untill 80-90mph then the x slowly pulls infront because of the torque!

 

You're probably talking about an out-of-tune X, or you don't know what you're talking about. The X will beat the air cooled from 0 to whatever mph.

 

That's a bit different than 'wont go over 67mph'. If it's shaking at that speed, then you have 1) bad tires 2) low pressure in tires 3) bad wheel bearings 4) maybe, bad steering head bearings.

I've seen some of the 700X ( and fazer 700) on youtube, and I doubt an airhead is in the same league as an X. But, as I only have the airhead, I can't compare directly.

but I have my doubts. . .

I've had my 86 700S up to 95mph a few times, and it was still happy to go more. that's enough for me though.

 

Holy GraveDig, Batman!

 

New guy didn't look at the original date on the thread.

If the X has 4.4 ft-lbs more torque than it has more HP
HP = Torque times RPM divided by 5252
8 = 4.4*9500/5252

I have a 700X and an XJ650 and they are in two different catagories. I don't have an XJ700 aircooled to compare it to.

 

umm ive had the x up to 135 and still acellerating is that out of tune?

 

my dad bought a candyapple air cooled maxim out of the showroom as a leftover in 86 his friend bought a maxim x out of the showroom thinking he was gonna dust the aircooled maxim. they raced all the time and the air cooled one would pull in front by a half of bikelength because of the midrange and it holds the x up till 80mph or around there then the x gets in front by a bikelength. yeah in the end it will be faster than the aircooled because the 10 mph difference. we just got an air cooled one to go with the x and the same thing happens when we race so

 

anyway put your money where your mouth is come down here with your x and bring it on i will beat you to on a 0-70 anytime

 

I love how the color of the bike is somehow relevant to the discussion.

The "X" motor is a 20-valve (5 per cylinder) FZR motor and Yamaha dropped it in a Maxim frame. Between it and the V-Max, I think they're still trying to get even for WWII.

The aircooled 700 is a first-gen, 8-valve motor with considerably less horsepower.

Both bikes are very close in weight.

No contest, unless one of them isn't running right. (Probably the "X" because the valves are such a bitch to adjust.)

The 700 is a nice bike, but my (100+ lbs lighter, chain drive) 550 Seca is quicker 0-70.

Stop while you're even, Josh; you dragged up a 5 1/2 year old thread to make your point.

 

You read 2 many books. There was a big mistake on CLAIMED power who ever wrote that everyone followed it. Here is a real article posted in cycle magizine on rear wheel horsepower between the 2 not all this claimed power crap. 700 air cooled 59 rwhp max x 75rwhp both attached to the same dyno. If they both made the same power how come the x is over 1/2 sec quicker in the 1/4 mile runs the same as a seca 900. If you look closely on claimed power again says the 750 seca has the same power as they both do. He is a copy of just 1 true motorcycle article comparing the 2 http://www.maxim-x.com/maximxj700_cycle ... .html.What fitz says is correct its a royal pain to adjust the valves in the x tho only good part is they do not sink into the head nearly as fast as the 2 valvers because of smaller lighter valves don't need nearly as much spring pressure.

 

"Between it and the V-Max, I think they're still trying to get even for WWII" what do you mean the bikes are too fast for the frame or somthing?

 

I mean that neither machine was meant for much other than straight-line speed; and that both are (and were) way overpowered for their size/weight.

 

i got my 1985 xj700 air-cooled up to 110.
