Hi eveyrone, i'm new to using forums so please bear with me. Also i'm still a learner and do not have much mechanical experience.

I've got a 2008 ybr that i bought in october 2012, the lad i bought the bike from admitted to pressure washing it a couple of times (he was a newbie too) which put me off though he reduced the price by £150 so that kept me interested. The bike on the odd occasion would start first time though 90% of the time it'd be second time start. Over time the bike is taking more and more tries to start. I changed the sparkplug yesterday and that hasn't helped.

Could anyone give me some advice of things to check/change?.. as i don't really want to pay garage prices for something that may be easy to do myself.
The only thing i could think of is moisture in the eletrics or maybe a new fuse?

Thanks,
Craig.

Check battery voltage when bike running and check voltage when not running. Post results here.

What was the colour and the condition of the old plug?

Turned off - 12.59
lights ect on - 12.06 (drops .01 every second or so)
when using the electric start it drops to below 9
and when running sits around 14

thanks for the quick replies guys!

If the bike is spinning over quickly enough on the button but just not starting, don't waste money on a new battery Wink

If it hasn't had one since new, you could try a new plug cap to go with the plug. Check the air filter and make sure plenty of fuel is getting to the carb.

Whats your start-up procedure? Do you use the choke always? Could the choke be sticking on?

yeahh thats the one!
probably should have a clean of the air filter simple job that i havent got round to doing yet!
the new sparkplug makes a little difference but nothing drastic and the problem of it not starting first time is still there :\
