i was just wonderin what kind of top speed you would get out of a piped jetted and filtered with the 16 tooth counter shaft sprocket

 

Don't know but when i get mine put back together with the new Powroll 770 kit installed from Thunderbay Powersports I'll let you know what the top speed is with 16 - 40 gearing.
My top speed with 12 - 40 was 75 mph first pass,74 mph second pass,and 75 mph third pass.

 

what is the stock rear sprocket and would a 16 with stock back make you hit 95 to 100 a friend did this and said he was up to 100 could it happen or not

 

Yes it could happen ..with pipe and jetting changes. But you have to understand that it's very easy to get to these top speeds of say 90-100mph ..alot of quads will do that ..but anything faster is very hard to do because you have to over come the friction of having 4 wheels on the ground and all the moving parts (piston gears chain everything that moves) + wind resistance.
If you take a stock Quad and try going with the 16 tooth front sprocket you will burn your clutch out before you ever hit 90 mph.
And other then impressing your friends top speed is worthless. It's how fast you get there that matters.
I used to have a 87 Banshee that went 107 mph on ice (but you have to understand this was a perfect day clean ice no wind and tires pumped up to about 20 psi)

 

I agree w/Rator690 and you know you will loose lot of bottom end plus it will take awhile to reach that speed. By that time you might run out of room before you have to slow down.

Why you want to use 16 tooth on the front? I did use 15 tooth on the front and I lost some power on top since the gear was too high.At the same time I was using 39 on the rear with 22" ITP tire which gave me 15/37 gear ratio and I learn the hard way while racing out in the desert of loosing the top speed.
So I went back to 41 on the rear and 14 on the front. Which will give me 14/39 with the 22"tire. That will be alot faster then the other set up as I mention earlier.

You would need a built motor like 686 or 727 kit to achive that top speed.
Stock motor won't able to get that top speed of 16 tooth on the front.

 

my freind has a raptor piped jetted said he got it up to 102 with the 16 tooth
cant happen i take it

 

I very seriously doubt 102mph ..like I said in the post before ..you can get one up about 90-100mph with small changes, but anything over that takes big bucks.
Goes the same with snowmobiles ..almost every snowmobile made now days goes 100 mph ..It generally takes something bigger then a 700 twin to clear 110 mph and 1000 cc triples only go about 120 mph.
Doesn't make much sense that a 700 twin is only about 10 mph slower then a 1000c triple.
Unless you factor in Wind Drag ,Track Drag, Engine Drag,Wind resistance,weight,Ski Drag,Suspension drag ,G-force of the track spinning.
You can take a 1000hp Engine mount it in a 72 Pinto run a few passes down a drag strip then take the same 1000hp and put it in a drag racing chassis and you will be ten times faster with the same engine.
Why you ask?
Wind Drag , Engine Drag,Wind resistance,weight,Suspension drag,tire drag,transmission drag,rear axle drag.
Get my point?

 

i got ya so hes full of $hit with his 102 mark

 

I would say so ..Be standing there before you trust or believe anyone.
Unless they have been reliable in the past .
lol friends are the worst to pull your leg .
cause they know you won't get all pi$$ed at them.

 

Hey Mojaveman
If your friend got up to 102 is that he did on the street or out in the booney land?
Or on a downhill paved road? Tailwind with 40mph

I really find that hard to believe he got up 102mph!!!
