Re: Bike running rich & jerky at low rpm

Finally got my VTR sorted :D I ended up buying a second hand pair of carburetors (they were a lot cheaper than I thought they would be) which had good needle jets, swapped them over and cured the shitty low rpm running. I'm pretty happy had been working on it since early January! I do plan to try an...

Re: Bike running rich & jerky at low rpm

Hi Stephan, thanks for your advice, but as far as I know those settings are for "48" pilot jets which are larger than my "45's therefore when you have "45's" they have to be screwed out further. I really need someone to advise if they know how to remove worn needle jets (gui...

Re: Bike running rich & jerky at low rpm

Have just pulled the carbs apart for another look and checked the needle jets (guides) as suggested my a workmate, they are definitely worn oval in particular the rear one. As previously mentioned the bike has only done 14K, but there was a lot of old hard petrol varnish build up on the needles whic...

Re: Bike running rich & jerky at low rpm

I'm fairly sure the chokes are all good, they feel like they are returning and moving freely. But I have noticed that when I pull the choke out after it's warmed up it does't seem to affect the running in any way. I've managed to borrow a 90 degree pilot jet adjusting screw driver but it's fairly di...

Re: Bike running rich & jerky at low rpm

Unfortunately I haven't any luck with my bike yet and I'm really not sure what to look at next. I have checked or rechecked the following - valve clearances and they were fine - rechecked the carb balancing and made a slight adjustment - I have only done approximately 100kms with the fuel system cle...

Re: Bike running rich & jerky at low rpm

Have checked the chain tension and for frozen links, it all looks good.
I brought some Penrite fuel system cleaner today so will add the recommended dosage and use the VTR next week and hopefully I'll see an improvement

Re: Bike running rich & jerky at low rpm

Thanks guys for your feedback much appreciated. I'm fairly confident that the chokes are all good and seating properly, but will recheck if I end up having to take the carbs out again. Will definitely get some fuel system cleaner this weekend and hopefully after a couple hundred kms I will notice a ...

Bike running rich & jerky at low rpm

Hi, I'm hoping someone can help with my VTR it is running rich and is very jerky in the 3 to 4000rpm range which is about 100 - 110kph, once I open the throtlle it seems to be fine. When I first test rode the bike before buying I didn't notice this probably because I only took it for a short ride an...

Hello from New Zealand

<t>Late last year I picked up my third VTR (finally a red one my other 2x were black) after deciding to sell by CB1000R, I use to live in the city and the CB was great to zip around if not a bit of an overkill for an 8min commute. I now live in a small town and my commute is 22min mostly on the open...
