Over it! was created by lobstermobster
this bike is becoming a reallll pain. anyway, rewired the bike and put cheap-o pod filters.( yaya im stupid w/e). running real lean (supposedly allready lean from the factory, so the no ristriction pod filters didnt help) looked on kz info got some info. Got the dyna jet kit. came with 118 mains and i order 17.5 pilots according to what kz650 info said.
Installed the jet kit and the pilots today, and its still running like shit. starts up ok, idles alright could be better i guess. but cant even get up to 1/4 throttle with out it just dying. even if it is warmed up. it does it ever time, you can throttle slow or gun it and it still just dies.
I dont know what to do.

Are valve clearances within specs?

If your not a motorcycle mechanic, familiar with the Japanese models of this era, I would strongly suggest purchasing the Factory Service Manual, and performing the ENTIRE maintenence section before any purchasing/parts additions are made.
There are a minimum amount of specific nechanic tools you will require to make engine checks like suggested by Patton.
They are very simple, and cheap to correct in most instances, and if slightly off or not functioning perfectly, will cause all sorts of troubling issues.
It will save you $$$ and get your bike running.
Do it, just DO IT.
Will it rev up fine with the choke engaged?!?!

No. It will not rev up at all.
And I believe I have the shop manual for it. I am not that motorcycle or mechanically inclined, yet. My dad is and he has been helping me learn. The thing is, it ran fine untill I parked it last October. Over the winter I ripped off all the unnecessary stuff and at the end of this summer I finally got it all back together. I haven't touched anything on the engine, all I did was put pods on.

Buy some sea foam and add to the gas if you haven't cleaned the carbs. Roy

@patton: I have not checked the valve clearances recently, I mentioned that to my pops and he thought it would be a good idea to check that. thanks.
And ill run some seafoam through there. We cleaned the carbs recently and they looks real good from the start. Checked them out today when we installed the jet kit and they looked good all around.
AND just to add.... there is lots of backfiring. real loud crackle and pop. I can hear it coming from the exhaust and the carbs. maybe that info will help someone determine what what i should check.

Check your carb manifolds for ANY cracks or dry-rot.Any air sucking in there will create havoc.
Exhaust...any chance a critter made a home while it was parked?

I'll check the manifolds. I put a brand new set on there last summer. I live in GA so with the cold winter and really hot and humid summer they could have gone bad. I have the stock exhaust on, so it would have to be a really tiny critter. And ive honestly never seen an animal in my garage before so if one did that one be pretty funny.

Check the Gas Tank Valve, Petcock, maybe the brass screen or little mesh filter is clogged with sediment???

so i got it figured out, for now. For some reason recently have been having trouble finding the small diameter fuel hose in the right size, so my pops had just picked up some thick bulky shit. i think its almost a 1/2 inch wide. yeah,... well there was a fine line of not having enough, and then too much and it would be winding all over the place and there wouldnt be enough pressure to pass the fuel through the roller coaster of a fuel line. And that thick bulky shit wont bend, it just kinks. So if you look at it the wrong way it gets all *******.
so basically rigged up a new line with what we got and it ran like a champ, kinda. but ******** awesome compared to before we installed bigger jets. I even ripped it around my neighborhood for a few minutes. I was just rocking a tshirt and an open face helmet and it was allready getting cold as hell so only a for few min tonight.
So now, def need to get some smaller diameter fuel line, and just sync and mess with the mixture. hopefully ill be ready to roll soon.
