GZ125 Marauder: Poor running.

I have a K5 2005 model year Suzuki marauder and it has been running very poorly ever since it became cold. I've done about 7000 miles and i've recently had it serviced. I find that at times it will not start unless i open the throttle while cranking it over. I also get power lag quite a lot, almost as if the bike was about to run out of fuel, yet there is plenty in the tank. I have also found that after running it at high speed for a few minutes it will die once i let the throttle off, and then it becomes difficult to start again. I have heard a loud rattling kind of noise coming from the engine when i rev it up to about half of full throttle while not moving.

I'm quite worried about this as i am hoping to sell it next spring and i dont want to have to fork out loads to repair it in order to get a decent price for it.

Any help or advice would be great.

Thanks

Liam

I'm not too sure on what it could be i'm afraid but i don't think the rattling and the dieing are connected. the dieing sounds liek carburation to me and the rattling could really be anything, if you bought it new then should it not still be under warrenty? if it is just take it in n ask them to take a look at it for you Thumbs Up

Yes I thought I would probably end up doing that. Will i not still have to pay for labor while they take a look? I have over a years worth of warranty left.

Most garage offer a parts and labour warrenty i woudl think they would look at it under warenty if you have the papers handy have a look and see if your covered for parts and labour, i'm pretty sure you will be with it being a new bike Thumbs Up

The performance symptoms you describe match not using enough choke. In winter you should use the choke on full to start and leave it there for a good few minutes. Don't think that you need to switch the choke off before you pull away.

It is in your interest to back it off as soon as you can, but not to the detriment of the performance of the engine.

After pulling away, try setting choke to half and then switch off only when the engine is fully warm. If the bike is air-cooled this could even be up to 30 minutes.

Too much choke = bad performance, too little choke = bad performance. You have to gradually put the choke in as the engine warms - you can judge when by how it runs. Feel free to experiment.

Re noise - could be cam chain, but rare on a bike lower than 1 yr old. I'd check it on warranty.
