Shifting problems
 

Got 3000 Miles on my Hawk 250 2015. The chain jumped the front sprocket today. I put it back on and tighten the chain. Shifter is not making contact with any of the housings and it seems to be making all the right noises but will not shift out of first. Help please any thoughts or comments are welcome

Have a look ...The chain may have bent the shaft the gear lever is on the end of...




.

I would check the output shaft for the front sprocket to make sure that it is not bent or sheared. You could also have a crack or a piece missing from the engine center case around the output shaft.

Did you lose any oil?

Wow, what bad luck. Is the oil level still normal? What gear was it in when the chain jumped the front sprocket? Turn off the engine, try rocking it back and forth while pulling up with your hand on the shift lever. Take the chain off (I would never use that chain again), and see if that helps. If that doesn't do the trick, I hope you are mechanically able, because the engine is going to have to come apart...ARH

Shifter not bent shifter shaft Not Bent bearing looks good no cracks in housing not leaking oil .shifter worked fine for the half mile ride home. That's when I tighten the chain and the problem happened........... Could the chain be too tight??????

Easy way to find out loosen it up a bit.

Remember you need about 25mm slack on your chain.

Colorado is on the metric system? Most everywhere else in the USA, 7/8ths of an inch slack.

gas on gas off while riding and trying to shift the wholetime might unjam whatever

I found out the hard way that 3,000 miles on a stock chain is pretty much the max. I threw the chain on my TT 250 and cracked the sprocket cover. In fact the bike wouldn't start at all afterwards so I had to haul it home. The next day I went out to see how much damage I had done in the daylight and found out that the only damage was a crack in the sprocket cover and it actually started so I replaced the chain haven't had any issues with it since. I personally would try to adjust the clutch and see if that helps because when I threw the chain on mine it spun up and shut off before I could hit the kill switch so it's possible that it may have tweaked things just enough to be out of adjustment.

You should also check to see if the chain slack measurement is with or without weight on the bike. I know that the TT says 15 mm on the bike but in the manual it says that it's 15 mm weighted.

Uni bear is such a great chain for the cheap why take a chance with the oem,replace it Hawk and TT250 owners.The Oem chain needs a lot of adjustment and if you are not on top of it that is when it bites you.

Sounds to me like a bent shift fork . Seen this before on a few bikes in the 80's .
These motors are cheap . I am not sure at 3000 miles I would even open it up . But that's just me .
Sorry for your loss. As I have been down the busted bike road a good many times . I feel your pain .

Yes, Chuck, you are 100% correct. On top of that, worn chains raise hell with sprockets. So, if you don't replace the chain early on, you get to replace the sprockets as well...ARH
