Semi-new on forum. After reading other threads, decided to put in 106 kit. Used S&S 570 cam, with headwork and compression releases. Finished assembling, ran starter several times with fuse for fuel pump removed. Then bike started, ran a minute or two and turned off. left sit for awhile and repeated. Ran through old battery and a new battery. When she started, ran very ruff and backfired. I am new to a rebuild, any ideas? I'm not sure how she should respond on first starts. Thank you for any responses.

 

it should start right up & run fine.make sure your mapped at least close.what tuner are you using? wondering too why you just didn't use EZ start cams,wouldnt have needed the compression releases

 

Did you get the cams timed properly?

 

Thanks. I think I got the cams lined up - checked the timing marks on the cams, checked the timing marks on the gears, checked the difference between the gears. Using a power commander V.

 

Also, I have not mapped anything yet.

 

Did you install new plugs? When I did my 107 build I didn't think about needing different plugs and I had a hard time getting it started. It coughed through the air cleaner and ran rough. Installing Screamin' Eagle plugs fixed the problem.

 

Download a map that is close until you can tune it but even still, it should run, just might run a bit rough.
I've never had to change plugs after 2 upgrades. Bought new ones but never even fitted them

 

Adjustable push rods, I assume? Poor adjustment?

 

Thank you for all of the help. I tried the new plugs, HD screaming eagle for high compression, attached a battery charger - she started right up, ran for a bit then died as if no gas. When she ran she sounded awesome. Using a two-brothers exhaust. Using the original push rods.

 

Kirby might be able to help here but not sure you can use stock PR's with that cam.
