Hi all,

I have an 2007 ER-6F with just over 2000 miles on it, and from new, it sometimes surges or misses (can't really tell) anywhere up to 4500 revs on steady or small throttle openings.

Accelerating or decelerating gives no issues at all, and the problem does not exhibit at higher revs or even at all sometimes. On the first service I mentioned it, he checked the fuel system and said it was fine and perhaps it is just the cat...

It dosen't do it when cold, and more likely to do it when I've been riding for a while.

I thought it may get better with more miles on it but it hasn't. It's not really anything more than an annoyance, but I'd like to know if anyone else has experienced anything similar?

Thanks!

Interesting, found this user review of the Er-6 on MCN...is this common?

I bought this bike as my everyday commuter & workhorse, I have had it 9 months and it has covered just over 8000 miles. The engine is excellent the only fault being a little surging on small throttle openings. The same with the ride & handling the chassis only complaining when being really pushed. In terms of reliability I have had several serious electrical problems resulting in complete failure, the bike packing up completely, a new loom ultimately had to be fitted. I have just fitted a new back tyre (8K is not too bad on a BT020 - have replaced it with a BT021) I noticed some corrosion on the swing arm, it is used in all weathers and is also showing the usual signs of dulling and furry fasteners. I have fitted a Scottoiler which results in coating the underslung silencer in oil but I do like my chain well lubed. Overall it is a great little bike and the problems that I have experienced are probably a one off and it seems to be fine now.
