zxr 750 running rough as fuck :@

[Pol Anorl]

This bike is causing me so much stress right now.

was having huge issues sorting carbs, finaly got them balanced!

still running rough, turns out on the airbox where there is 6 thumb and a bit sized holes there is supposed to be bungs which it didnt have, so i filled em started it up sounded better and didn't bog down so much at 4k-5k rpm.

Next was to look at the inlet for airbox at the back, 2 hand sized holes, filled em with some rag and boom didn't bog down at all.

so i set about making some covers for the inlet to bring the size of the hole down as i didn't have the original tubes for it (not the ducts at front before anyone asks)

Made them it was still a bit shitty at 4k-5k but a hell of a lot better.

Took it for a test pulled away and it flew like a beast, turned round came back, struggled to even hit 40mph started running like utter shit.

FML!!

Any ideas?

Did you get the valves done in the end? If not, probably best to get them done before any carb fiddling.

I had a h1 a while back and found new plugs, aftermarket filter and an oil flush made a surprising difference. Also found the pipes to the fuel tap could kink easily although that could have been my bro in laws work. Mine flew like a banshee when i finally sorted the pipes out. Needed some effort but for a 22 year old bike she surprised. Just kept eating alternator belts so had to sell.
For the plugs in the air box you may be able to get them from either a breaker or ebay but mine was missing some with alternatives wedged in place. Amazing what fits.

ffs man, do the bloody clearances,
zxr's never get loose tappets*, they get tighter and tighter,
then you get a valve that doesnt seal, then you get a melted valve,
as above, a bit of rattle is no bad thing, too quiet is too tight,



* when i say tappets, i dont actually mean tappets
