Title: Question¿¿¿
Post by: 700rSE on September 21, 2008, 03:59:12 PM
hey guys havent been on in some time. i got a question though, i have a 660 and so far ive only got to like 105km/h (thats like 65mph) and didnt if thats like a usual top speed? mayb its less cuz im like 215lbs.  also i got a friend with a 400 arctic cat sport quad and he says he can do 120, id be ashamed if i lost. so is there any way i can get more power/speed for cheap? thanks


also my reverse knob is loose and very tricky to get it to work, does anyone no how to fix it?

ok i got a  question that will benefit everyone trying to help
is your raptor stock?
if not what have you done to it
Title: Re: Question¿¿¿

Expect 71 stock,  75 at the most with big 3 mods.  Carbs probably need a good cleaning. Or speed limiter is acting up. Have your sprockets been changed? If mods have been installed, you may be jetted wrong.

110kph is 60 mph, so I think you may have problem. I may be wrong.

My reverse knob is tricky as well.....It broke, and I zip tied it back down.

I was thinking maybe a clogged air filter
and ehh peels 110 kmh is like 69 mph
Title: Re: Question¿¿¿
Post by: exentix on September 21, 2008, 05:38:02 PM
try going up a notch on the front sproket, that should give ya like 3 mph more  :thumbs: and im sure a full pipe, good jetting, and a nice big ol' filter can make it even more  :thumbs:

ehhh you dont even need a full pipe
pick up an hmf off of ebay for 220 dollars  :clap:

no disrespect but you do realize we are talking kmh not mph
and a arctic cat 400 has a suzuki 400 engine which IS capable of doing 66-68
but ur right it doesnt even come up to 120 kmh

Post by: exentix on September 21, 2008, 06:24:14 PM
ok but still, a 400z should not be able to do 60+ mph
Title: Re: Question¿¿¿
Post by: darkside94 on September 21, 2008, 06:40:53 PM
um sry exentix but a z400 is a lot faster than you think
prolly faster than you  :lol:
but  :ot:

someone get a mod down here stat
Title: Re: Question¿¿¿
Post by: exentix on September 21, 2008, 06:44:55 PM
yea its faster than what i have but believe me i can hold my ownto a stock z... and ive done it a few times

my former best friends neighbor has a 400z with a yoshi full pipe, and when mine was piped and jetted i could keep up with him on his land, where i never rode before... and the guy we ride with on state trails has one and i can kinda keep up with him, but the suspension holds me back alot, hopefully not anymore tho cas i took out my lowering kit

A stock Z should go 66-67 mph

Front sprocket
13T   -5 mph
14T    stock
15T   +5 mph
16T  +10 mph

Rear
36   +3.2 mph
37   + 1.6 mph
38   stock
39   -1.6 mph
40   -3.8 mph

on a 660? just to make sure


but if a stock z does 66-67 then a stock raptor 350 should do about 60 and ive been told thats not even close downhill  :confused:
Title: Re: Question¿¿¿
Post by: Bert on September 21, 2008, 07:36:59 PM
Those gears are for a 700 but the change in mph is the same for a 660 or whatever. One tooth in front is equal to 3 in back

Without any mods the top speed may not increase because the motor is underpowered for tall gearing & you have to account for wind resistance which eats up power

sorry for the late reply, it has a k&n airfilter and the guy i bought it from (not even a month ago) said he had is rejetted and cleaned the carb or what ever. 60mph=like 96-100 kph. also i got my reverse working. and thanks for all the replies

I would say pick yourself up a nice slip on exhaust because without an exhaust that k&n isnt really helping much. About what is your budget  ???

Slips ons have limited performance gains. The head pipe needs to be replaced for maximun performance.  A slip on will make it louder  :lol:   I would spend the money once & do it right, find a pipe that meets your DB requirements.

Hey Krandall...he did. I am not sure what the mini hos did to this thread. :lol:

700rse:  Try speed sensor removal mod, if it does not change anything ,I would say go ahead and clean the carbs...new air filter. Adjust throttle cable, could be strectched, and too much play, but that is a long shot.
Title: Re: Question¿¿¿
Post by: Krandall on September 22, 2008, 09:06:13 AM
oop, my bad. I musta missed that.

the only thing I can think of OTHER than the carb.. Is if the previous owner played w/ the gearing,
Title: Re: Question¿¿¿
Post by: 700rSE on September 22, 2008, 11:10:29 AM
he never said anything about changing the gearing. but you think its the carb? not that im a bit heavy for it so it doest quite do what its capable of? because i was reading some stuff and the 660s usually dont do more then 70mph(112-115kph) so maybe i just slow it down? thanks again

I wouldn't consider 215lbs overweight by any means though.

Hope not, I am right at 200. Mine is a clunker and still managed 73 with similar mods. Maybe problem is electrical.....does it sputter at full speed? If so, that is your speed limiter, just a guess.

Post by: fastraptor on September 22, 2008, 04:40:52 PM
If you are using smaller diameter tires than stock then you will be geared down and need to increase the front sprocket size or reduce the rear sprocket size  :) to go faster
Title: Re: Question¿¿¿
Post by: 700rSE on September 24, 2008, 08:16:49 PM
im pretty sure it does not sputter at top speed next ride ill listen for that. also the rear tires are 20x11 and the rear ones are 21x7. also would the tires being kinda low on air pressure effect it? i dont think it would that much. thanks

yes, incorrect pressure would affect it quite a bit.

Post by: 700rSE on September 27, 2008, 12:15:00 PM
so the other day i went and checked how pressure was is the tires, and they didnt even make it come out. Do you know the right amount of psi or kpa? on the side of the tires it says no more the 250KPa and thats like 35psi, but i think i saw some where your only supposed to put like maybe 4psi. whats the correct amount?

Depending on terrain/rider weight 4-6 psi would be a good start

I believe that max press on side wall is just for beading, more than that, one could stand a chance of blowing the tire apart. ???

As far as press, it really boils down to personal prefferance, to much , they feel like rocks, to little ya stand a chance of debeading easier, and or damageing side walls due to pinching from rims meeting ground with tire side wall in between. :(

I do believe proper tire press per rider weight makes all the differance in top speed, and ultamate handleing of bike. :thumbs:

I am an avid MX racer and am allways adjusting tire press per conditions of track, I weigh 160 and for the most part run between 5 & 7 psi on all 4 and seems to work good even doing 80 & 100 ft jumping. :clap:
