Hondatrx300ex and I put the chain and sprockets on last night... Well I was riding wheelies today in front of my house and the bottom chain roller broke! I was wondering If it would be okay if I rode it without the roller, it gives the extra tight chain some room to breath!! Thanks,

 

Having your chain adjusted to tight may have caused your roller to break. Spend the $10-15 for the roller. A chain that flies off your sprockets can do major damage. Proper adjustment of the chain is very important.

 

I'd suggesr you adjust your chain to factory specs before riding again. a too tight chain will cause stress to the counter shaft & will do damage to the tranny eventually.
