I'm gonna throw a few questions at you all about re-jetting :

What are the pros and cons for re-jetting a carburetor with an after-market kit?
I do understand the basic principle regarding fuel:airflow differentials...

But have you done it and was it worth it to you?

What is the average bhp increase?

Is it worth doing it without modifying other exhaust components?

Are there any recommended after-market kits?

Forgive any of my ignorance.

Whether its woth doing depend completely on your desire for change on the bike. Do you plan to do it yourself or pay to have it done?

With stock everything you are going to get some better throttle response which tends to feel like more power. Without a pipe, I doubt its worth the $ or the effort as it can be niggly.

Half way through you may regret the whole thing. I just did both my hawks and 2 of my racebikes and would recommend you focus on riding & save the headache.

 

looking at you location, and remembering my geography, your altitude above sea level probably means you bike will need some carb fettling as it could be running lean.

Is re-jetting worth it - in my opinion yes.

The bike will run smoother, pull stronger, and that annoying flat spot in the upper RPM's will be gone.

The con - you will use the throttle more

As far as recommended jet kits - there is factory or dynojet. Or you can skip the jet kit and shim the needles.

 

Some great advice gents. Yes indeed in the "mile high city" my bike runs rich. Its tuned for high altitude. I've been as high as 14,000 ft (4300m) in the mountains here and definitely still encountered a lot of power loss. Which is precisely why I decided to re-jet this weekend based on all your respective advices. I'm going to do the work myself. I wrench on my truck and my Cessna 172 so I figure it won't be a stretch. But I havent wrenched a bike in 15 years so wish me luck!

Also, if any of you come through Colorado this summer, hit me up with an e-mail here and I can point the way to some extraordinary and challenging riding. - Scotty : )

 

Good luck; should be no problem, just remember which side the long trumpet came off of. ( I always forget). And use a pen to get the springs compressed back on. If you have the carbs off it may be worth dremmeling a slot in the fuel screws to make life easier.

 

Not to mention distracting views that would suck your bike right off of the railless roads

 

@VTRSurfer
It was the Mt. Evans road just West of Denver. Highest paved road in North America. I've ridden that road between Durango,Ouray and Silverton. Lots of pucker factor. Really the most dangerous part of mountain riding is the cars because they can't keep their eyes on the road. Lol...
