    Since I just went through this today I noticed the torque spec is antiseize and 20ftlbs...that's nothing. I actually put blue on it at 20, I'm not sure why the starter wouldn't call for loctite I see no good reason. I was just following the manual before but obviously that's not working out well so loctite it is.

    Well it finally happened. The starter housing cracked. I am trying to figure if it is the chicken or the egg thing. Here is the sequence of events leading up to the failure.
    1)I installed a slam switch and after that I had this scenario of the starter sol would pull in and nothing would happen for about a second and a half and then it would turn over and start.
    2) I replaced the battery with one that everybody liked and the problem did not go away and then started the bang that I talked about when I started this thread.
    3) I let it bang every once and a while and continue to do the grunt and then start thing and then removed the starter and replaced the bearing on the output end of the motor and checked the wear on the clutch basket teeth. They had some wear but not alarming.
    4) Seems like the occasional bang was louder and one time the starter stayed engaged even with the key off. I attributed this to a mechanical misalignment of the starters output gear. The sol did not want to pull in after that. After about tan tries it started.
    5) I removed the starter and found the case cracked by one of the #10-24 Socket head cap screws that mate the sol to the starter, Not in the starter to primary case bolts.
    6) I had removed and disassembled the starter before and thought that I had possible tightened the #10-24 to tight and stressed the pot metal causing the case to crack.
    I have found a way to reinforce this area on the starter to prevent the breaking problem but I do not feel that it is the root problem.
    7) I do not think it is the compression releases because it does not even start to turn over.
    8) I have a wire plus system and I haven't read the voltage drop across the sor relay. I will do that when I put it back together.
    9) I noticed that the wear pattern on the clutch basket teeth are only showing partial engagement, about 50%. It might be that the wear is preventing the sol from coming all the way in and there for making a poor connection momentarily to the starter motor causing the 1 to 1 1/2 sec grunt in starting.
    10) Is it a hardness problem with the clutch basket teeth and something that we inherited?
    11) Has anyone looked at the amount of engagement of their starter gear while starting with the primary cover off.
    12) This is not going away. If it is a baker problem did they fix it or do we have to go the Bandit basket method?
    I appreciate the replys by Th3infamous, BWG56, pknowles, Badyellowvette, BadDawg Bill and others.
    BTW I have about 29,000 mi on the 06 K9.

    I cracked two housings and even the nose. The force in these things is unbelievable something has to give and most often it's the housing which cracks.

    I've also had cracked teeth on the starter gear itself which obviously will hang up on the ring gear on the basket.

    After I cracked two of them I replaced the starter ring gear on the clutch basket and a new starter gear on the motor. How does the starter gear look?

    My opinion is the bang is due to the starter gear when its trying to disengage and it get it's hung up on the gear. As mine always happened at the end of the cycle and most times the bike was running.

    If I were you I would just remove the slam button, they cause more problems then they are worth and I had an adjustable one from spyke and going down the road the nut backed off and the damn starter just kept spinning! That was fun as I was at a red light. I shut the bike off and it's STILL spinning! I've never actually needed a slam button and if you lost your hand control start you can always jump the solenoid wire a little wire.

    Mine bangs going in and does not do the 1 to 1 1/2 sec grunt delay when it bangs.

    What started my whole problem was the clutch hub nut coming loose 3 times and the last time I put it on to stay but I still had the bang because the damage was already done to the starter ring gear on the clutch basket. When I replaced the ring gear I also noticed the clutch hub bearing had a flat spot in it also and ended up replacing both the starter ring gear and the clutch basket to the tune of about $750. Replaced the clutch nut with a hardened one and had it bleeding red loctite when I hammered it on to 150ft# torque.
    I have been bang free ever since I replaced these items over 2 years ago.

    One other thing is do you have a rebuilt starter in there now? If you do, pm me for more info, it has to do with the starter gear itself Iphone2016 186 (2).JPG

    It's specific for 2005 plus. Baker is only place to get it and they make you buy the whole basket at the tune of $400.
