Can I get just a little more power??
 

I'm looking forward to starting my second season with my GZ250! And as its snowing I'm inspired to look up some fun mods I can do when the snows gone but its still too chilly to ride.

My bike is my daily commuter in on dry days, mostly 40-55 mph no highway. And its Illinois, so there aren't really any inclines. But I could use a little more power to feel safer.

When I leave work, its onto a 45 mph road for a mile, then 55mph for 2 miles, and then up a hill. I'm not sure if its still warming up or under powered, but it HATES getting up to 55mph that soon and slows down by about 5mph going up that hill. With semi's on the road and driving in the dark, it just doesn't seem safe.

Is there a mod I can do to get a little more top end power out of it? Would it be considered torque?

I'm hoping to avoid trading it in my beloved gz250 for a 450....

mod the carb an air cleaner
i have this seating for a year an I happy

pilot 2.5
needle shim
140 main jet
mode air cleaner

It will do it in 4th gear.

I think it is time to get cut haha !

Peanut!...what part of Illinois are in you , I'm jsut across the border in the Hoosier state. We get lucky that we don't have much in the way of inclines, I couldn't imagine riding the geezer in a mountainous state.

I totally agree with Raul. I've done the carb jetting, etc, and ripped out the air box and its been worth it.

There are several power upgrade guides on the site:

It really depends on how you're riding though. If you ride like it's a a larger cruiser and trying to power up hills with low RPMs, then it's going to struggle. But I live in an area with more inclines and really enojyed my mountain passes. Just drop it into 4th and enjoy the fact that it's a light and nimble 250.

Thank you all for the replies!

I've seen Jamie's Power Increase thread. To be honest, I only remember to look when I am at work... when all the pictures are blocked... But those 2 links show how to do what Raul suggested too, right? I'm, uh, new to motors too... I hate working on cars, but the gz is fun to wrench!

But perhaps I just need to downshift? I can drive a manual car but never have for more than an occasional trip once a yearish. So I'm quite green to knowing when to downshift. Will sitting in 4th gear at 55mph cause any damage? It sounds so harsh up there!

Oh! And I'm in Joliet riding to Morris. Probably right down the road from ya Goose!

Peanut. If possible do you have the opportunity to take a run at the hill at 60 or a bit more? 60 will be closer to max hp and torque of the engine. You will still likely slow a bit but not down to 50.
Lynda had the same situation with her GZ. A long grade that she more or less conquered with speed. Hit the bottom of the hill at max speed and slowed to 50 at the top.
Her M-50 could start at the bottom at 50 and a slow twist of the throttle could easily top the hill at 100. There is no substitute for displacement. Use the throttle when needed or gear down and maintain the speed of 55 going up hill. And yes, the GZ will sound like a potential grenade but it will hang together for the odd hill. A steady diet of high revs will give it a shorter life span and repairs.

Peanut,

Looks like we are about 2 hours apart right now. Might have to get together for a ride when the weather turns nice again.

;) :)

The poor little engine that could. :)

There are tracks at the bottom of the incline. They are usually fine, but I'd rather not hit them at 60.

2 hours is nothing Goose! And, uh, thanks to jon too...

Will the real Jonathan please stand up.. lol

What?

I just think all these Bromances are "cute"

That photo would scare me off....

Qasual: I still think you should just get really cut and get that beach body ! Haha win win situation. More power and you get core strengh for epic lean angles and positioning.

Someone gets me!

Qasual, if you're 2 hours away or less, we can "ride" together anytime.

In my defense, I'm the sexy one in the picture...I'm not the only one who knows which one that is right? ...Right?

10 points if you can name who they are.

Hint: Music

Jon...exactly what kind of music do you listen to?

Qasual - The bow chika wow wow kind ?

lmao...nice

Flight of the Concords, you sugar lumps.

You post an image like that and then insult us. Now there's some balls...pretty sure the same set you can almost see in the image. haha
