ok guys i have almost 9k on my 05 636. i havent had a problem until i was on my way to lexington and on the xway my bike started sputtering and then just shut off??? it started right back up and ran fine so i took it back home. the next day i was riding and it started sputtering, it didnt die just ran like ****. it seems like it will run fine for about an hour then start running like ***??? last time i drove it i was taking off from a light when i was getting on it in 2nd it just jerked the **** out of me, it wouldnt rev past 11k. i was wondering if it was in a safe mode or what. no FI light, temps were fine everything???? do u guys think its misfiring, maybe need new plugs? and y after an hour does it start running like ***????? PLEASE HELP!!!!!!!!!!! thanks

 

Plugs and lack of voltage can cause what you mentioned.

 

HOw long was it sitting before you started having problems? Do you keep it insibe or outside? If you keep it outside do you keep it covered?

 

I would start by checking all the connections, and making sure you don't have a bad ground. What kind of mods have you done?

 

The 05-06's have had some problems with the throttle bodies. First try a water remover or fuel treatment like RXP. If that doesn't fix it, call the dealer to check on a recall or service bulletin. Other's have had similar problems.

 

i keep it outside covered up under a carport. mods: jumper mod. i had a b&m air filter on it but i took it off because i thought that might have been the problem because of different air flow. i took it to a dealer and they said they couldnt find anything wrong with it. i put some fuel injector cleaner in it and that didnt help either.

 

How long has it been sitting ? Make sure your gas is good. Also check your battery voltage. also try un doing your jumper mod.

 

yea i thought it was bad gas at first as well, but ive gone through 2 tanks since that

 

Also check you vacum lines that are under your gas tank. Did you have the tank up putting in a filter or anything? if it started running like **** after this it could be a vaccum hose check that if you want. Make sure none of your fuel lines are pinched either.

 

Yeah do that ^ and put some RXP in your tank. Trust me and atleasttry this. The fuels now have Ethanol in them which absorbs water. It settles at the bottom of your tank and gets sucked in the fuel pump intermittently which causes rough performance. Check you battery terminals too for security/ tightness& corrosion.
