I'm looking for pics of bikes that have open chain primaries,
I'm contemplating a belt or old school chain, thanks

 

Do the belt much much better

 

I have a belt drive for a shovel 1 1/2" PM if interested, scott

 

I run a 1 1/2'' BDL belt on my shovel.
Chain drives pretty much require to be enclosed so they can be in oil.
I've had a belt system which used a large roller bearing to adjust the belt tension and found that they aren't a good idea and create to much heat and every time the engine stops the bearing cooks the belt in the spot it comes to rest on.

 

if your going with a open belt, which looks cool and cuts down on vibration, get a 3" off ebay, i have seen many of them for under $400.00 new. Item number: 200304930930 this one is $375.00 new.

 

not sure which I'm going to use yet, but thanks for the advise!
