Fixed. The rejetted bike will have a higher top speed.

But what about the guy that has a rejetted bike AND lower gearing?

 

Jabara - 150hp, 380lbs !!!!!!!!

I want two of those!


Bolted together...


Pulling me in a chariot...



Naked..

 

Oh, and Anthony.. More power to ya.. Best to study black magic cause a 24hp fully uncorked KLX is gonna run off and hide from your 18-19 hp (maybe as much as 20) weezer and will need a "hex" put on it before you race it..

 

snowdrifter, yes jetted AND regeared is going to be the fastest, absolutely. I was only comparing a jetted bike with stock gearing against a regeared bike with stock jetting.

Let's get back to the original post. I spent 20 minutes and $10 and gained noticeable more grunt. I could spend much more time and money and gain even more grunt, I understand this clearly. In fact, I'm not even knocking doing more; God knows I have with many of my other toys, both carb and FI, in fact. I was merely saying an easy mod that makes a difference. Does the gained grunt compare with rejetting, yes. Does it compare with a regearing AND rejecting, no.

 

 

Seriously! MotoGP bikes are approx 250hp, 400lbs with tons of electronics. I'm not sure what Jabara is referring to, but damn, that is a nasty fast bike he has there.
The fastest bike I've ever ridden is a Honda RC51, it was absolutely insane! I can't imagine how badass jabara's must be.

 

I dunno where you've been the last 20 years. How about like...ANY 750/1000 sportbike......~150hp or more and sub 400lbs.... so like I dunno, multiple thousands of bikes out there..... so exotic right? hahaha.

I'm not the one going on about his $10 sprocket swap that has changed his KLX into perfection (since no more mods are needed per you) ...that thing must rip now man.... hahaha, thanks for the laugh

I dunno why I even bother with this guy, enjoy the 19hp -1 sprocket monster you have there. -1 sprocket is all you need guys, no need to mod any more. Exiting this exciting thread....

 

Ok understood I will try

 

Damn, you are so defensive and disagreeable. The sky is blue. "No, it isn't!"

Going back two decades is a bit much, are 750 sport bikes even still built? 20 years ago they were, granted. But not sub 400lbs. I thought everything was 600 and 1000 for the most part these days.
Admittedly, I don't ride sport bikes any longer. I know many bikes have the hp you mentioned, but under 400lbs? I had't realized any bikes were that light. I did a very quick Google search for recent models, and only found one. Aprilla, but its not a 750cc. It is interesting though, you don't mention your exact model.

For the record, I just happen to have a 750 at home, not a sport bike, and it weighs about 400lbs. But only about 50hp! 2010 Moto Guzzi V7cc.

 

No, it's still a dog, no where near perfect, nor ever will be. It's just a cheap KLX250. Not a race bike, not even a real dirt bike. Spend the time and money you suggest. And, it's just a KLX250. Not a race bike, not even a real dirt bike.
