[robleen69]

well hereit is i have a 88 kat 600 i took the tank and plastics off to have it painted mind you it ran excellent 3 min before i took off the tank now parts back from paint bolted everything back up and bike wont start good spark threw starter fluid in carb started up then died tried for hours will not run any ideas

[scottynoface]

Did you hook the tank up right? Did you drain the carb bowls and forget to prime them when you got it back together?

[bizzy102]

Pinchedthe fuel line or carbs have no fuel..Maybe vaccum line on the rear of the petcock is not hooked up..

[robleen69]

1. never had a hose on the back of the petcock
2. ill check for it tommorrow wat does it hook up to

1. never had a hose on the back of the petcock

Yeah , that's gonna cause some problems .....
There's a small hose from carb 4 that SHOULD go to the petcock .

ok back to the begining the bike ran for bou 20 min to warm up sounded fine... took down the street and it bogged out and wont start again... please help guys

you sure your spark is good? i took my tank off for painting, it ran great when i parked it. When i went to start it, it refused to crank, and it turned out 3 of my plugs were fouled.

you afterfiring at all?

[robleen69]

it did backfire a couple of times when i took it out for a ride it stoped running bout 1/4 mile from my house had to push it up hill back it was not fun.... im gonna change spark plugs today does anyone know wat size socket the plugs on there are... today itr started back up as soon as i give it gas it dies could this be spark plug issues

[arsenic]

explain this "back fire". Did it happen when you slowed down after you let off the throttle?

[robleen69]

def part of it was plugs ....changed those ran fine once again but died again sprayed starter fluid in the intake started up but sound like starving for fuel... believe it is my petcock.. because i do remember trying to empty tank and it only did drops not poor out like it was supposed to do u guys think this would be my issue ......it only works somewhat on the prime position not on the on position at all....





yes arsenic it backfires when i let off the throttle it also sound alot different then it did before i took off the tank

[Rangerx52]

well what are you doing to test it? i believe the petcock stays closed until the vaccuum line is actively sucking. If you want flow from it without vaccuum, then you turn it to prime and it'll flow out- but why would you want that?

What are you idling at when it warms up (or rather attempts to)?

[robleen69]

idles perfectly but then i close the choke and it goes to bout 800rpm instead of 1000rmp ... but when riding it sounds like starving for fuel like i said it ran 100% before i took off the tank
