Best 426 mods for under $100

HI i have had my 426 for about a month now and love it. I was just wondering witch mods made the most diffrence to ur bikes performance, riding style or what ever for under $100? Also ive herd that the 426 pulls stronger and will beat a 450 (05 and below) sraight out drag race is this true?

What's a "witch" mod? Is that something my mother-in-law can do for me? Fact is, the 426 is the fastest bike to ever grace the face of the planet. Don't ever let anyone tell you different. $100 will get you a very cool sticker kit that will add about 15% more peak power.

buy a airfilter and jet kit

Regear it. A 2 tooth larger than stock rear sprocket will make it "feel" like it gained a few ponies.

Save a few more $$ and install the 03 exhaust cam.

93 Bucks + Tax got me a 450 Cam, and then of course you need a little extra dough gor shims

Save a few more $$ and install the 03 exhaust cam.

I agree!

Ya buy an 03 exhaust cam so you can have the ease and power like my 03 450. No 426's arent as fast as the 450 ( 450 is bigger than 426 :applause: ) Not much difference but No is your answer

The Auto-Decomp cam modification using the '03/'05 450 cam is the one of single best mods you can make to the bike, and runs right at $100. Once you've done it you'll wonder why everyone doesn't.

When a 426 and 450 are geared to have the same first gear ratio, the 426 has a 3 mph higher theoretical top speed. The 450 is some 15-20 pounds lighter, and has 2-3 more hp. All of which means that they're so close it's up to the rider, even in a stupid straight line drag.

Save a few more $$ and install the 03 exhaust cam.

I agree and then get a ZipTy adjustable Fuel Screw and a DRD Hot start - they will make your life easier 80-100bucks for both

The 450 cam mod would be my first choice. But a good bolt on performance part for under a $100 would be a Boyesen Quick Shot. I just got mine and I think it adds alot more throttle response.

hilarious !!!

im not so shure i wanna spend that kinda $ on a 03 cam just for the ease of starting. Its easy enough to do it now. + i heard that it makes your bike loose a little hp.

Trust me, the 450 cam mod is one of the best mods you can do. Also, far from costing you power, most people find the '03 cam adds a little.

For a list of other 426 mods, check out Motoman's web site. Just go to tech articles. :applause:

As far as loosing horsepower...NO There has been no technical data to even back that up. What people seem to calculate to loss in HP actually is responsable for the increased smoothness in HP across the power curve with the cam. I know when I did the cam, and once I got used to how much smoother the bike ran, I also started to think along that line, but its not true. The smoothness gained with the 450 cam is unbelieveable, and I would do it in a heartbeat again if I had to...

increased smoothness in HP across the power curve with the cam...:eek:

I hate this smooothness sheit! I like unadulterated displays of mind numbing power, come on man!

Best first mod for a 2000 426 is R&D P-38 Lightning, adds great throttle response, which fulfills my earlier point unadulterated power, say it with me now

un a dul terat ed p ow er! There you go now say it 19 times while tapping on your forehead, standing on one foot & drinking a beer. :applause:

The reference to smoothness is not a reference to limpness.

What we mean is that the 450 cam, while it adds to the peak power, adds even more to the ends of the power curve than it does to the fat part. You will have the arm stretching, "mind-numbing" power that makes people who try your bike out come back looking awe-struck, but it will no longer have the sudden step in the mid-range. It will be the kind out floor-to-ceiling, electric-motor-on-steroids kind of power that a 427 Camaro has, not like a BMW M3.

Boyesen Powershot Accelerator Pump Cover. $80 on Ebay.

The BK mod is a lot cheaper than the aftermarket AP covers and probably works just as well.

It also has the advantage of infinite adjustability going for it.

If you have an '00 426 you really need to put the '01/'02 carb needle in it.

Cheeze, you crack me up!
