Let us know what you think of the sprocket.
I would not go back.
The break in seems fine, I went easy for a while, but the last few rides I was running normal mode (beat the crap out of it).
I got odd noises from the motor, mostly when its cold, when I was out riding in the cold rain it was bad, on the hot days it seems to go away.
Its like a gear rattle, and I think its the crank balancer gears or the starter gear.
There seems to be a good amount of slop in all the gears. Room for expansion I suppose.

I have about 1500 miles on the bike, about 700 on the new top end.

I might order some more of those rubber plugs to stuff in the fins, I think I hear it because its a plated cylinder and it has all those fins on it.
Nothing looks wrong inside the motor, no metal, no loose bearings, everything works like it should, does not use any oil or smoke, shifts great and the hotter it is, the better it runs and the less noise the motor makes.

Brett, (and I'm saying this seriously!) all you're hearing is Suzuki AC bike noises that are normal (esp for the singles).
I call mine my little ice blender! (cause that's what it sounds like)
Even my old 1100 Katana made noises (and it was way smoother) and never blew up. (and I was young and TRIED to get her to blow up)
Stop worrying about it!

And, if any of you guys are interested....I'm off the weekend of the 7th-8th if you want to get a 250 group ride going. Actually on vacation the entire week leading up to that as well so...

Girlfriend is off to California for the week and my plans are, fishing, riding, fishing, riding...you get the idea.(oops! left out internet porn)

I was glancing through my dad's latest Popular Mechanics and they had a review of MOST 250cc bikes. And when I say 'most', I think you know what they DIDN'T include. They had they GZ, but not the TU.

Woo-hoo!!!

16T sprocket arrived today. Put it on after work. Took about 10 min. Got in a quick ride before the storms rolled in. So far I'm lovin it! Makes 1st & 2nd so much nicer.

Thanks for the 16T advice Brett.

Wish mine would arrive...still waiting for the second one I ordered from Amazon. At least it's in transit...probably sitting in customs

Finding Neutral

Just curious. On a scale of 1 to 10 (1 being really easy and 10 being nearly impossible) where would you guys rate "finding neutral" on this bike. On mine, sometimes I'd say 3 and sometimes it feels like a 8. I've only got about 600 miles on it so I'm hoping things get a little easier when I get some miles on it this season (if the weather ever improves here) I might even try adjusting the position of the shift lever a little - seems a little too low for my liking and may be more an issue with my boots than the bike

Took a 10 mile ride tonight. Had my first stall. Was coasting down a hill with the clutch in to a stop sign, and it cut off. Seen this before?

Fuel light came on and it took 2.3 gallons to fill her up.

Wow what a fun and nimble bike :)

Mine would occasionally die if the bike was indicating low fuel and I continued to ride a day or two on short trips around town without filling it. Only experienced the stalling in city traffic, never happened if the tank was low and I was cruising. I'd attribute it to the gas sloshing around from the stop-and-go traffic and temporarily running out of fuel...

so i'm positive that the headlamp i bought is defective. i'm sending it back.

i tied up all the loose headlamp bucket cables and took the bike out for the first time since the wreck. the clubman bars make it feel like an entirely different machine! it's incredible. she's running like a champ, i can hardly believe it. seems to be driving straight but i'll have to have a shop look into that when i take it in for a post-wreck check up.

Yup, I've had the stall... Usually in the first ten minutes of operation, always when clutching in. Hasn't happened much recently.

Neutral is a pain, I'd rate it an 8 especially compared to my other bike which has a positive neutral finder.

My bike has never stalled.
I did turn the idle speed up a little, but it never came close to stalling.
The ecu might do something on coasting, so if you pull the clutch in it might stall?

The 16 tooth is great, big improvement, and the GZ rear sprocket makes it even nicer, you guys might want to try one also.
My bike keeps running better and better, I changed to synthetic after a ride tonight, 1 quart of mobil 1 v twin 20w50 and 3/4 quart of the racing 4t 10w40.
So I have 15w45 I guess.

My bike shifts great till it gets hot, then its typical, and oil change usually makes it better. Sort of like an oil change timer.
It gets better with more miles, and I think its better with synthetic oil.

I thought I read a review of the TU on line done by popular mechanics...

Had that start happening to me when I had about 600 miles on the bike. Turned out to be the throttle stop adjustment screw. Simple adjustment. Haven't had any problems since.

+1 on the stall - same exact thing with me. Happened a couple times, especially if the bike was not warmed up. Come to a stop sign at the end of my street, pull in the clutch and she just dies. It's never happened when the bike is warm though. I'm hoping when I get around to installing my Memjet module it might eliminate that and the "surging" I get at times as well. I'll let you know if it works.

This may be an interesting read for those of thinking of doing the 16T.

I've decided to leave it stock - I want to keep everything stock mechanically during the warranty period.

The oxy sensor does nothing at idle, so a memjet wont do anything for the idle.
Did you turn the idle speed up a bit?

There are two settings, the throttle STOP screw, and the idle speed screw.
The TU has two throttles, one cable operated, and one the ecu opens, and the one the cable opens has a throttle position sensor that tells the ecu what you are doing with the throttle.
The ecu operated throttle also has a throttle position sensor to tell the ecu where that throttle is at open wise.
There is also a bypass port (the big flat screw) that lets air past the ecu operated throttle.
The ecu operated throttle has that ramp on it that pushes open the cable operated throttle to control the fast (cold) idle speed.
I don't ever coast in neutral or with the clutch in, that is not good for the motor, its better to leave the clutch out and let engine vacuum pull oil up to the top end.
Try turning the big flat screw clockwise a bit till the idle speed goes up a bit and see if it stops stalling.
