ZXR250C carb help wanted

[Spoonrider]

Thanks man, has been an ongoing saga with this bike lol

They can be a bit troublesome
Another thing I'd do, while playing with carbs, is remove the cam chain tensioner and clean it, they get gummed up occasionally and will cause rattles, and in bad cases they'll fuck out and the chain jumps teeth
It's pretty simple, just on the back of the block below the head, two bolts to un-do, then a central bolt to take out once removed (careful, there's a spring up it) then take it apart, clean, check the teeth on the tensioner arm aren't chipped or work. A ZXR manual will tell you the spring free length to measure
Put it back in, take off the front left engine cover and turn the motor with a spanner about three times so it resets, then it should be as good as gold.

I clean mine every oil change, paranoia!

how dirty is the inside of your engine!

mines self cleaning, I add a bit of dishwashing liquid into the oil and run it for 100km then do oil change. Fuck its clean in there

It's sparkling bro last oil change (500km ago...) I whipped the sump off, did all the o-rings, perved at my crank and annealed the copper washers for the oil cooler
After polishing the sump...

So, I had a thought... why don't I just get a second hand standard muffler and put that on and problem solved....

The standard ones are just slip on aye?

[ducatilover]

Yeah, pretty sure they bolt on to a flange

Or, get a nice air filter and set the carbs up. It'll sound nice

[Spoonrider]

It's more of a temporary measure to get the bike rideable for the mean time while I get my self organised to work on the carbs and do the airfilter.

What is a good airfilter to get for these and where can you get them from?

[ducatilover]

OEM.
You won't get any gain from a K&N or Unifoam without setting the carbs up
