Hey guys i have an 05 1200c with an kandn intake and se2 mufflers and after iv been riding it for awhile and i turn it off and come back 2 mins later go to start the starter grinds and quits then i hit it again and it starts it will also backfire to when this happens can anyone tell me anything?

 

my 883, with 1200 jugs, (with too much compression) will do this when hot..
I think it is because of the dual fire ignition..
(front cyl fires 45degrees early along with the back cylinder)
fuel vapors ignite causing piston to push backward.(.backfire out of carb.)
In fact mine broke the starter ring off the clutch basket..

I cured mine , by blipping the throttle a few times, before a hot start..kinda floods the cylinders. and get her spinning before the gas lights off..
another way would be a single fire igniton , or a front cylinder compression release.
OR a guy could re-wire the starter button so that the engine would spin without the killswitch being on = no fire to plugs untill engine is spinning..then turn on killswitch..

all of this is just my opinion ,experiance ..
Owned this sportie since new ...1991 model

 

i was having a problem like this for a while. it turned out that my 5 year old battery was on its last legs-new battery and no problem.
where are you in iowa? i'm from hancock county.

 

The starter clutch gears on the Sporty starters are weak. It's OK for the 883, but the clutch gear won't stand up to the kickback from 1200's higher compression. After going through 2 starter clutches in 24,000 miles, I replace the starter with a stronger 1.4KW "All-*****" brand starter. That was 40,000 miles ago, and no more starter/kickback problems.

BTW, your motor is already Single Fire.

 

Be careful of the hard farts when it does that. For me it blew off the vac line to my petcock.
I found the solution to be not to bump the starter switch but hold it down for at least one FULL second.

 

+1 cHarley. I've gone through 4 starter drives (starter clutch) in the last 4 years. It is a common problem with the 1200's. One of the pistons will be near top dead center. When you press the starter button, the spark plug fires before the piston can move up. This causes a kick-back against the starter. I found, if you "tap" the starter button rapidly once on the first, try it will fire the plug without the kick back. This has doubled the life of my last starter.

 

thanks for the info guys ill have to try a few of these ideas and see if they work on my bike. mycle1000 i live in story county.
