FZR600R Stumble

The old girl's developed an annoying hesitation in the 5K-6.5K band under load.Going from the overrun to on the power the bike actually slows down as you open the throttle, then it clears it's throat and sings all the way to the red.I think I felt it go one day, about 5 miles after filling up from empty (my reserve light wasn't working). I was wondering if some crap had been dragged through the pump and is blocking a jet?I've pulled the float bowls and they looked clean, I've removed the main jets and emulsion tubes, also clean.I didn't pull ...

Daytona fuel in oil

When checking my 2001 daytona 955i oil the other day I noticed that it smelt of petrol. I read that it could be that the mapping could be way out and over fueling and could possibly be pushing fuel past the cylinders. But I downloaded tune ecu put the correct map on, changed the oil but it now smells of fuel again. I then took the injectors out re connected them to the tank and repreasureised the fuel system and my injectors seem to be leaking slightly? Is this the reason? Or do they naturally leak? So so so confused!

CBR250R cruising hesitation

My 2011 CBR250R is  second-handed. It had run 7700km when I bought it. It is 14100km by nowIt's  easy to start and idles fine.Nothing seems to be wrong while playing throttle without load.But it hesitates while crusing at any gear any rev-range.The other thing is that when I give light gas after decelerate , the power won't be smooth and stable for a short period of time.No matter how carefully I give the gas, it feels like the engine pulls the chain and let go 1~2times in a short time , and then starts to accelerate smoothly.It's uncomfortable and dangerous ...

Yamaha YBR 125 G block tyres, good for winter?

Hi, I am a new biker and purchased a yamaha ybr 125 g to learn.  The g model is the on/off road model that comes with block tyres.  I've heard that the tyres may not be good for use during winter on the roads.  Is that true? If so could anyone advise which tyres would be most appropriate for winter road use (live in Cumbria so roads can get icy and cold)?

Appreciate advice on this please

Evening all, I recently changed jobs and, in order to avoid the overpriced and unreliable public transport here in the big smoke, I decided to buy a motorbike to get to work. I've held a bike license for nearly 18 years, but have been out of the loop and haven't had to insure a car or bike for the last 10 years. I headed over to to put in my details and see how much the they were asking. The cheapest policy came in at around %XA3200 mark. I should add at this point that I wanted to keep ...

Aprilia RSV4 Factory APRC

I'm looking to change the standard pirelli diablo supecorsa sp's (200 on the rear). I'd like something more suited to our mixed weather in the UK, ie good in dry + wet, and warm up quickly. The bike can recalibrate itself to 190, 50 or 55. I've used Dunlop Sportsmarts before on other bikes, but looking for advice. Thanks
