How many miles are you getting on a front sprocket?
I'm thinking of converting my 08 Night Train to chain.
I'm getting tired of pulling the primary down to replace belts.

How often are you reaching them? The belt should outlast a chain.

IMHO you have just had some poor luck as of late. One with stone damage and one IMHO is a factory defect .

The original belt passed a rock through it and broke at about 25kish miles. The replacement was an aftermarket and was defective. Lasted about 4K. The current one is an OEM with about 28K on it and the teeth are ripping off of it.

If a front sprocket will last 60K or more I'm going to convert to chain. I never had to replace a front on any other chain bikes other than dirt bikes.

IMHO it is a factory defective one too . Gates did ( maybe still do) make the belts, they should last 100,000 miles easy. Gates powerbelts are the "goto belt" for powertransmission applications .

I went through plenty of chains due to stretching and rear sprockets on various crotch rockets years ago. I don't recall ever replacing a front sprocket though. If I did it must have been easy.
The process to put a new belt on a left drive Harley is a big pain in the azz. Not hard to do but takes a while due to how much has to come apart just to get to it. I can put a belt on my Sporty in 20 minutes along side the road.
I found one front sprocket that says it is case hardened. I'll continue the research until I get a definitive answer from a manufacturer as to longevity. Chains and rear sprockets are not a concern.

I'd like to know how you guys got by without replacing front sprockets. The standard recommended procedure is both sprockets when the chain is replaced, if not the chain life is reduced a bunch. All sprockets wear, and that wear will wear a new chain really fast. And in my opinion, if you think you are going to get 60,000 miles on a chain, on the Night Train you are fooling yourself. My guess would be closer to 25000 miles.

Personally I like the belt. Most I have heard have lasted as long as most bikes. The ones that don't have had stones get in them.

After doing some research it seems that 25K may be a high estimate for a chain.
My 60K target was just a starting point. Everything I read so far indicates the front sprocket may last through 3 chains and that includes the accelerated wear on the second and third chain.
I was hoping for a hardened front that would have lasted much longer.
I pulled the bike down and found some stone damage to the rear pulley I'm guessing started with the first belt issue.
I'll be going back with a belt and a new rear pulley.

Sounds like a plan!!! Sorry for your bad luck so far.. But that should fix it...
