Just doesn't sound right

Hi All,

After a year out of the country where Bryan looked after my bike, I've been using it this summer. When I first started up the bike, I forgot to drain out the old fuel, so the thing was really lumpy struggling to pull away etc. I used the bad approach of getting the thing to the redline to clean out the carbs with fresh fuel in there.

Since then, the bike has been a little lumpy at low revs. After warming up, its appears to be more or less fine. With higher revs, its its old self.

But when I got back from a run this morning, the engine just doesn't sound quite right.

I've had the cat for 6 years now, so know what it used to sound like, but can't really explain it.

I'm assuming I have some crap in my carbs still, but wanted to see if anyone had any suggestions before I start pulling it all apart.

To try and explain what it sounds like, its just a subtle noise under the normal rattles of the engine.

Can't be much more specific - will go outside and have a listen and see if I can find anything obvious.

Anyway - hello all and I hope to say hi to anybody who's in the north west soon.

Don't worry guys - sounds like its getting better after all the old fuel additive I could find got dumped in and some more fresh fuel.

Will run it for a while and then clean the carbs out properly.

Later

Hi Fella and welcome home,

Now this may sound a bit daft but in the known issuses pdf booklet on site there is a bit about running lumpy and it turned out to be loose battery connections,

Silly but worth a look, if only to clean them up and put some protective gel on em and make sure they are tight.

Thanks Tel,

Did actually check out the old FAQ just in case.

I did check the battery terminals, but that wasn't it. I recently replaced the dead battery from when I was away as well, so know its not that.

Does appear to be getting better, so I expect it will sort itself out with the continual thrashing.

Just need somebody to ride with now.....

Simon

Maybe a downpipe has sprung a leak?

have you checked the breather pipe sometimes it gets blocked

Thanks for the suggestion guys.

After a good thrashing and another tank of new fuel, it feels and sounds much better.

I'll keep my fingers crossed and see how we go.
