Pulley chain tensioner blew off - good replacment?

The Grubee device with a toothed roller is the most ideal. Currently working on a DIY solution by using a rear derailleur roller as a replacement for the plastic roller - if its not good will order a Grubee.

May get rid of the tensioner completely and ride without one.
 
I also use the boomerang one on my 4 strokes, the previous photo wasn’t a good pic but I use it on a 2 stroke

Hey, I tried that. If they made those little guide sprockets out of metal it might have worked. But otherwise the thing just spun too fast with a motor behind it and it burnt up and flew apart.

Do you think it's okay to use a sparkbuster on a bicycle? :ROFLMAO:
 
It’s best if you can get away without one at all, always good to keep some half links on hand to help with proper tension, also make sure chainline is straight

Absolutely
 
I use those little mufflers on everything. I've found that the 3/4" ones screw right into a bicycle seat post, perfect header.
That's exactly what I did, then put some wrap on it, was running STR8 header, then I noticed the cops were raising eyebrows at me, so I got the muffler, but not before they hit me with several warning tickets, but the muffler does take away a little power.
 
I personally don't really understand the use of the rigid "arch" tensioners. The spring loaded ones vary tension with load, and assuming the appropriate rate spring is used and load set accordingly, it will almost eliminate the low end "lurching" that the rigid "tensioners" cause to be transmitted to the wheel.

I could see using the arch if it also had the idler on a spring loaded moment.

The grubee style (I prefer the nylon wheel one however. quieter) is the best option.

The arch's, while they work for alignment issues, are pretty horrible at what they are intended to do...... maintain a consistent chain tension.
