How on earth do you access the balancing screws on a zxr250 without dismantling the whole bike? The only way i can see to get to them would be to remove the radiator and fan, but then i wouldnt be able to run it

I read through that one for the zxr400 but my carbs seem to be 90 degrees different then those ones, so my screws are facing into the rocker cover instead of being upright like the ones in those photos

fuken aucklanders.

Take them off and bench sync them, for a start. Then stop being a pussy, put them back on the bike, take it for a fang, and tweak the balance.
Are you sure youre looking at the correct screws, not the air pilots?

Haha allright bro, so once ive bench synced them and put them back on and taken it for a ride an realise that they are still as unbalanced as they are now, I run into the exact same problem. Yes, I am sure they arnt the air piots, the four air pilot screws are facing toward the back of the bike and are very accessible, then the three balance screws are on the other side tucked up in no mans land

Hmm....that seems really odd, I was under the impression that the 250 used Keihin CVK D30 carbs whilst the 400 uses Keihin CVK D32's so there shouldn't be bugger all difference....

If they really are that hard to get to you'll probably need one of these: http://www.motionpro.com/motorcycle/partno/08-0119/

Yeah man I borrowed my mates right angle screw driver thing like the one on that link, an could access them from the R/H side with the fairing off, was still a pain in the ass to adjust them accurately as his tool was a real old school genuine Yamaha one, but worked out sweet in the end. Cheers for the help
