ER5 Sluggish

[gazzaroo]

Hi Guys

Got my hands on a 2004 ER5 with 8k miles. Recently changed air/oil and sparks and she was running fine for about 30 miles.

Just got on it today and noticed she's underpowered. When I open the throttle it is sluggish and not going very well. It does seem noisier so I'm wondering if it's the spark plugs - I assume that's the best place to start.

I have another question too. When I was changing the plugs I noticed that one of the cables going into the spark plug cap could be pulled out. I pushed it back in and all was fine, but is that normal? I thought the cable and the cap were fixed/attached?

Any help greatly appreciated!

Screw the cap back onto the lead.

Latest updated. Added some treatment to the petrol and left the bike running for a few hours.

Before I did that, it would rev fine till around 4k revs and then "stall" and then surge on to higher revs.

After a few hours - it now seems to rev nicely right up to 8k rpm

Any ideas what it may be? Some dirt in the carb?

Thanks

That`s crazy,
Ok you have added a more volatile fluid and got better results so get the carb/s sorted and fit an inline fuel filter.
