It appears that shorter primary bolts were used. It took a little time, but I have been able to figure out that this was a Primo 14mm belt drive with a 24-tooth front pulley and a 37-tooth clutch basket. I have never had an issue with 8mm belt drives in the past, but I have only run 3-inch and 2-inch open drives. I was opening this up and was expecting to find a chain, but instead was treated by that mess. So now I get to decide if I am going to clean it all up and replace the belt or put the entire primary drive back to stock with a chain. this was one of the nicer shifting shovels I have owned and it was a piece of cake to find neutral

Good day, removing the tank to run wires for an amp to battery, I disconnected the fuse for the fuel pump, but I still hear the pump when I went to purge it. All it did was turn over, it did not start, but don't want to unplug it while I still hear the pump. Should the line be purged if I run the starter for two cycles of about eight seconds each ? Thanks

If you can't find the clutch springs info, let me know, as I have a chart I made several years ago of some Harley, and aftermarket.

FWIW up in the "Sticky posts" there's a thread on clutch spring color codes that you might find interesting. Towards the end there's a chart with different spring part numbers, pressure etc.

On my 2010 FXDC I swapped out the stock "standard lite spring" for the "standard early  spring."

2010 fat boy 6 speed fm 110 kit  rider is 160 lbs 50mm tb 625 lift tman cam bike has 113hp 125 tq no slip as of yet  on dyno owner rides easy / normal no burn out should se spring be put in or wait till see if it slips at all

When I did my 103, made 115 foot lbs. I had to get the spring and take to tuner because it was slipping on the dyno

Bike weight, gear ratio etc?  More info may get you a better guesstimation.  That's all you can count on with no details.

Aprox how much hp tq numbers before se spring or upgraded clutch swap ?
