More power without engine work.

[cheetah]

I need more power. What can I do to get more power without going in to the engine? Give me a few ideas and if possible prices of about how much they are.

[Dave400ex]

Biggest one I can think of is a FCR 39 Carb. That will cost ya about $450...

[Sparks425Ex]

Carb-FCR39-$450

Gear Your Quad To Your Likings-Sprokets-Front-20-Back-50

You could get a Sparks Timing Key-$15 All You have to do is take your Ignition Case off and Flywheel off...

That is not in the part of the engine you are talking about I presume....

[cheetah]

Well I have a Sparks key lying here, but I have never installed it. I'm not the greatest of mechanics and I didn't want to screw anything up. Is it pretty easy to put in. I thought about the carb too, but debating between it and a rear elka. What would you do? Tell me what you think of the key installation. Does anyone have pictures?

[ridered86]

header pipe, remove choke, grind header welds, K&n filter:blah ummm thats all i can think of i think.

By a manual and learn how to work on your bike. The biggest asset that will help your machines performance is how well you understand how it operates and how to work on it.

JET it RIGHT.;)

[300exazzkikr]

Just remember there is no replacement for displacement.

[hawiianpwr]

I would say go for the carb either the fcr39 or the edelbrock quicksilver

[hawiianpwr]

The MSD ignition help out too. You can do anything with it. Adjust your timing -2 - +7 degrees, rev limit from 6000- 10,250rpms. Two stage rev limiter for drag racing. Its got multiple spark up to 3000rpm and twice the spark than stock thoughout the range; over 30,000 volts. Pretty sweet system I recommend it, my bike runs better, sounds better and runs cleaner.

My yz426 engine puts out a lot more HP then a raptor 660. so that doesn't always work. Just send your motor to sparks! haha. I'd say try the edelbrook doug eichner edidition carb

[gojk]

When you install the key how do you reinstall the flywheel. Do you guys press it back on or just tighten the bolt on the flywheel.

[UglyMotha™]

i just installed the sparks key on friday it was cake to do they even provide the flywheel puller just be sure to have a good strap wrench to hold the flywheel and it's nice to have a second set of hands cause it's not exactly a one man job it can be done but it's easier with two as far as putting the flywheel back on i just held the flywheel with the strap wrench and then took a 1/2" breaker bar and tightened the bolt as tight as i could get it and boom your done but before you rip your side case off be sure to pick up a gasket for the side cover and the starter cover cause mine was only a year old and they still ripped

[raptor_02]

i say go with the REAR ELKA. Motors mods come after suspension.

[hawiianpwr]

Good point. Go with the rear shock

[hawiianpwr]

You can only go as fast as the quads gonna let you!

[Dave400ex]

I agree 100%. Get the Elka...

[cheetah]

Yeah the Elka was what I really planned on doing first being a trail rider and start some XC this year, but my cousing talked me into going to the drag strip last week and you know how that goes. Kinda caught the fever a little bit.

[XxXx~FLY~xXxX]

what exactly does a sparks timing key do??

Hmm, interesting. So are you saying that without good suspension your quad will actually be slower? Or you just won't want to go as fast through stuff because of the suspension being crappy?

How are the works triple rates? without the reservoirs

[cals400ex]

the sparks timing key advanced the timing 6 degrees. this is supposed to give a little more throttle response and low to mid range power. it is not recommended for high compression motors and will make the engine run a little warmer. their are many mixed feelings about this thing so i don't know if it works or not. there is a thread going around now that talks about it.

[crashinmatt]

im goin with the other guys, get the shock first. or at least get ur rear reworked. then after that get a carb. personally id go with the FCR. i have one it was easy for me to dial in. i have a buddy with the edelbrock, and whenever he thinks he has i dialed in, he go for a ride, and then it start messin up. he told me that he will never recommend one to anyone. and this is comin from someone who knows their crap about quads.

[hawiianpwr]

yeah I'm saying through racing around. If you can't keep you quad under control your not going to go as fast

Anyone have experience with these? How good are they?

People probably don't quote themselves to often LOL...

[hawiianpwr]

I have a pair of works triple rate shocks without the rezzies for my 400. If your thinking about getting them. Get them! they are worth it. The ride is so much smoother and plush. They soak up everything and jumping is more fun because you can jump higher and further and the landing isnt as harsh as with the stock shocks. I bought them for $350 that includes shipping and handling

[Dave400ex]

Yes the Works are much better then stock shocks. If money is a problem you could get the Economy Elka's and add rezzies down the road...

[wilkin250r]

Nitrous Oxide Systems (a branch of Holley) sells single piston nitrous kits.:devil

[Sparks425Ex]

Well.....The Elka Rear would be nice and yeah ya can only go as fast as your ride will let ya go but.....



The Stock rear shock has alot of adjustment in it....You don't need a new Rear shock...Yet..

And If ya wanna get your engine built....Send the sucker to Sparks. I am a million times happy with mine...

And as for no replacment for displacment.....That is a Crock of Chit. I will put up my Sparks 416 up against just about any 440 or 425 that is not sparks....(Excluding TC) and I would bet it will win....

i bought works triple rates with rezzies. now stop...before you make a mistake like me save the extra 200 and get ur self some real suspension;)

Get someone to get off and push maybe?

I don't mean to be a jerk but could you give some more info as to why it's a mistake to buy the works. Also, how do you personally define "real suspension".

I'd be really interested in some concrete info as to why I shouldn't buy the works triple rates because anything else I hear about them has been good.

[Martin Blair]

pipe, kandn, also i am going to get a quicksilver carb, my parents are still paying for the bike so i cant do any engine work that will viod the wareenty so it all has to be reversable so im getting a TC pipe, grounding welds on header, and a filter, also it might take a while but get your jetting right it will help alot. MY 400 has alot of power and i dont evne have my tc pipe yet, but i alos have a 14t front sprocket which helps with accl. but not with top speed.

I looked on MSDs sight and cant find nythign on atvs, its there a link or some more info on the ignition system?

[tricke]

On a internally stock 400ex motor is a bigger carb going to help?
im just asking for a freind.

LOL - Do some searches and you will find everyone you could ever want to know about the different shocks that are out there.
