Need a Skyhawk 111 Expert

[dougsr.874]

About 45 days ago I replaced a hoot gearbox with a Skyhawk 111. Today on a short trip the Skyhawk gearbox locked up and left me side of the road...After finally getting home and tearing the gearbox apart, I found that several of the teeth on the clutch bell gear were worn down to nothing and several others appeared to have broken off, the remains of which were in the bottom of the case.. Before I bought the Skyhawk, I researched the item and thought that it was a far superior item...but it has only lasted for about 100 miles. the other gears show NO signs of wear...The gearcase was filled with 80 to 140 gearoil....I did have the engager locked in the on position all of the time...

Does anyone know if this is normal wear and tear???Any suggestions on how to prevent such in the future, after I replace the clutch assembly. Bicycle-Engines.com shows that they have the parts...Any other suppliers of these parts????

with only 100 miles ridden
this should not be normal wear
stories such as this -- only bring bad light to some motor bike engines
most if not all people ordering engines wish for many
carefree miles of riding as they ride those THINGS

did that THING come with any type of guarantee ?

be nice if you can post in the vendor area
we wish not for many more of these...

ride that THING -- when you can

After replacing the Hoot gearbox with the Stage 111, I found that even with the engine at lowest idle, apparently the clutch is still spinning somewhat,, so when the engager was engaged it was so violent that it stalled the engine...my soultion was to zip tie the handle lever closed and leave it permently engaged....Anyone with a better solution, please let me know....

You already answered your own question. You sheared the teeth off when
you engaged the engine at high rpms.
I doubt if that is covered by a guarantee........

Bicycle-Engines.com is the only supplier of these kits and parts

I think he said his box was engaged all the time. That's how most people run'em 'cause the nuetral is for people (of a questionable nature) who give the bike gas when they start it up causing it to take off if it's not in nuetral. I would think your supplier would replace it for you. The gear probably had fractures from birth; it just took a hundred miles to come apart. Inspect it closely and you may find evidence of this. Good luck!

How were you riding it? down a hill or going flat, let off gave gas clutch springs to life with too much force and BOOM!?

Letting off the gas and then giving gas should not cause the gears on the bell housing to shread. I have thousands of miles on type II and have gassed her hard at the bottom of hills 100's of times with no ill effects.

One would think factory defect?

Did you replace the hoot clutch with a grubee?

I would suggest not using gear oil (runs to hot) use lithium grease (thin with oil if need slightly).

dougsr.874, your post about the clutch still engaging at idle may indicate a broken spring.

 

[FireBellyCycles]

It's really likely a factory defect, as biketec has said.

Poor castings and low Q/C add up to lots consumer defects w/ no post purchase support/warranty which equals unhappy non repeat customer (I did the math).

Thanks

Thanks to everyone for the info...I can't make the engine idle any lower without dying...so it was not engaged at high rpm's...I plan to order a whole new clutch assembly, but this time I will never attempt to engage the gear while the engine is running, even at idle..the lithium gease sounds like a good idea

 

[HoughMade]

Good idea. Mine is never disengaged. So far, so good.
