Having problems with throttle response 1125r 2008

Having problems with the throttle response on my 1125r. When riding this morning, the throttle was unresponsive up to opening up half way, when suddenly it would fire up to high revs. Is this due to not riding for sometime (cable sticking issues) or a problem with the efi? bike seems to be running rougher than usual aswell.

Cheers,
Hamish

Could be that you need to do a TPS reset. Buellxb.com has a few videos on their site that will be helpful.

think it's in case of an accident. when bike is on it's side it will cut off the throttle action so nothing (you) won't get stuck between the wheel sprocket/belt.,,

SOURCE: Speedometer problem

Speed sensor is what it sounds like.  Could be as easy as taking it out and cleaning it off.  Could be a bad sensor itself or could be the worst thing and it be in the cluster.  At least that will get you started that happens all the time on the Harleys and most of the time its something to do with the sensor.,,

I had a problem when I first purchased my bike, I could start the bike 3 times and even after riding the bike would die. I ended up having to have the Harley Dealer come out and pick up the bike to fix it. Turned out, they had to "update the system software" on the bike. Hope this helps.

Try spraying carb cleaner on throttle body then check.If its running smooth then its fuel pump related issue.The fuel filter is either clogged or fuel pump is the cause of problem.Running rough actually indicates towards fuel pump issue.But still get it checked by spraying carb cleaner on throttle body.------ also recheck the heat sensor connections are they getting burnt or loose.If all getting checked ok, then it can be ECU related issue.But first check the fuel pump, filter, heat sensor connections.Also re check if the error code is changed.As you mentioned the buell runs fine with throttle open, it can be tps related error.Tps means throttle position sensor. ----------- If all checked ok, then yes it can be ECU.---------- This should help.Thanks.Helpmech.

08, 1125r...Just bought it. On my first ride i noticed gas drips from tube on the back of bike opposite side from exhaust. I assume this is an overflow tube but it drips gas for 15 minutes after every ride...


It is a known issue - you can take it into Harley but last guy I knew with that issue - they had the bike for a month and gave it back to him no changes said they couldn't replicate the issue. The gastank on the bike is getting hot causing the gas to evaporate and create pressure inside the tank - hence the gas dripping out of the pressure vent. Some guys have put some heat insulation in between the side of the tank/frame and where the headers get close. Other guys just wrapped their headers with thermo wrap - seems to help tons.

You need to pick up a copy of the factory service manual from either Americansportbike.com or your local dealer (part number 99491-08Y). The procedure involves lowering the engine from the frame, so it is not something that is easily described online.

I have been having a problem with my charging system on my 08 1125r buell. My battery light comes on while riding and the voltage system comeson my instrument cluster.


Go to your dealer and have the official Buell wiring harness mod fitted. Normally this will be under warran. The other possible problem could be your alternator. The dealer will be able to determine which is which.
