lost to bonestock 04

[MudDuck]

Hey guys ive been reading alot about what to do first to start modding my Shee. This is my first ATV so i am rather new to this but i have had plenty of RD/RZ's street bikes over the years. My 02 is stock except for a K+N kit, no airbox lid, no baffles in stock pipes and its jetted which seems to run about right. The rear sprocket is 3 bigger then stock. I wish i new more but that is all that seems to have been done to it. First thing i did was dropped it off at a buddies house that works for a local Yamaha shop and he checked everything over and said it runs fine. Well i love riding it and it is a blast in the trails but when i drag race it seems to lose to my buddies stock 04 Shee rather easily. Do you guys think a set of pipes would help? Also this thing really is hard to get to wheelie. I did do a Compression test and got 110 psi both cyclinders. So looks like the motor is fine. Thanks.

Next to porting, pipes are the number one biggest performance gain you can do to a banshee.

if you have a 3 tooth bigger than stock,its not pulling on the lower end like it would a 13 or 14 tooth front.i bet ya he's beeting you in a short drag,isnt he.buy some pipes and rejet and youll hand him his ass everytime.

His "rear" is 3 bigger which would gear him down. That still explains why your losing to him. When you both hit 3rd gear, he's turning more mph than you because your undergeared. Gearing down is not the way to win a drag race, it can be helpful in a technical environment, but put your stock rear (41) back on or go to a 40 and you'll be moving faster quicker. Make sense?

We are racing for fairly short lengths. He pulls ahead of me about halfway in 3rd and stays there. So the stock gearing is taller so that is why he has more MPH?? I was thinking i needed a lower gear(smaller front or bigger back) to get out of the hole harder but then again would i just spin more?

I would go back to stock gearing, 14/41 and get a set of pipes. you will be amazed. Then try a 15 up front.

where do you race at? Assfault or dirt or sand

[PUSH THE THROTTLE]

Sredish nailed it.

 

Put a 40 or 41 rear on there and a 15 up front and you'll destroy him for $30.

Yep. But if you are bonestock it might be a tad harder on the machine to run a 15 up front, but I'd sure as hell try. If you can pull it, you'll kill a stock geared machine similarly setup (like stock vs. stock). Most people don't even take into consideration gearing when they're thinking about racing and "I'm faster than you" stuff.

 

When I was stock with pipes, and geared 15/41, I'd waste highly modified mx banshees running 13/41, like they weren't moving, but it's not power, it's gearing.

 

Let us know when you beat his ass......

I'll just add this for an example.

 

14/44 Gearing:

2nd Gear @ 8,000rpm = 29.1 mph

3rd Gear @ 8,000rpm = 35.1

4th Gear @ 8,000rpm = 42.2

5th Gear @ 8,000rpm = 50.5

 

Stock Gearing (14/41):

2nd Gear @ 8,000rpm = 31.2 mph

3rd Gear @ 8,000rpm = 37.7

4th Gear @ 8,000rpm = 45.3

5th Gear @ 8,000rpm = 54.2

 

15/41 Gearing:

2nd Gear @ 8,000rpm = 33.5 mph

3rd Gear @ 8,000rpm = 40.4

4th Gear @ 8,000rpm = 48.5

5th Gear @ 8,000rpm = 58

 

While, the differences aren't huge, he's got you on mph right from the start, and there's no way you can stay there, mathematically impossible. Your shifting a little sooner than him, but you'd have to be doing some fast ass shifting to make it work. By switching the gearing around, your turning the tables. The secret to speed is finding the highest gearing your machine can pull without sucking the motor down (gearing it higher than the motor can handle). Try a 15/41 and get back.

Point taken but I've never had a bone stock engine I still prefer the 16 up front, but it'd be a bit much.

 

Another advantage to going up on that front sprocket is less wheel spin, the more traction you get the better as long as you keep the wheels moving forward.

no baffles in stock pipes ...

you should put your baffles, when my shee was stock, i removed the baffles and i noticed that i lost a little bit top end and its dangerous for the engine.. it cause too vibration to the motor..

[SHEEBANSAVAGE]

I am still running the stock setup.14/41...besides the chart that sredish listed, what difference will that make to top end? Also, I do most of my riding in sand, would changing to a 15 tooth up front be a good idea or bad for the conditions I use the shee in most??

That's hitting the nail on the head. Especially in sand. On asphalt low gearing may help in a short distance, but it's too much torque for sand. I had a 13 front when I got the bike and it would wheely easy but sucked in sand.

 

I'm not sure about not being able to wheely. I'm running about the same gearing as you and can easily pull it up in 4th or 5th. I know I'm pushing more power, but even stock you should be able to get it up in 3rd I would think.
