Posted: 00:57 - 15 Jan 2018 Post subject: Going up 2 on the main jet as a last resort Z500b |
|
|
The z5 hasnt been running right so stripped the carbs(tk22s) down for a nice clean. Went to put them back together and snapped the main jet
After 2 hours searching i can find a replacement #90 on its own and all the replacement kits have a #92 main jet in them(for the kz550) it doesnt help that i dont have a proper part number, its 92063-xxxx
So would going up and putting #92 mains in all four carbs be a bad idea? Its all standard except for a aftermarket pipe which is no way performancey.
Any help appreciated ____________________ Past: Peugeot Speed Fight 50 - couldn't handle winter.Gilera Sc125 - Crashed and burned(literally).Aprilia Rs125 - Fell apart and Sold. Mk1Bandit Stolen

Could you get smaller ones and drill them out (you can buy jet drills)?
Although going up 2 probably isn't the end of the world on a bike of that era.
That said, even wemoto are listing #92 jets for your bike. Sure it's supposed to have 90s in it?
The best bit will be when you find it was running badly because of a poor coil earth or similar. ____________________ “Rule one: Always stick around for one more drink. That's when things happen. That's when you find out everything you want to know.”

I'd expect #90 to #92 to be within the margin of manufacturing error, fuel quality[*], altitude, air temperature, humidity and density.
Carbs aren't an exact science, and I'd rather be running a touch rich than too lean.
