Valve cover removal

[chris032188]

yes it still did it - could one of the carbs ne flooded? It seems like when it was making the noise - a mist was coming out of the carb?

[steveb922]

From which part of the carb did this 'mist' come?

[chris032188]

Figured it out - it as the vacuum line on the carb. When i hooked it back up i ran the line between the tank and the frame rail which i believe was pinching off the line. once i rerouted it the bike is running fine. I appreciate all of your help!

Glad you got it sorted.

Welp.. More bad news haha Prior to doing valve cover the bike was running pretty good - idling good when warm, but was a little lean. After doing the valve cover while driving to my parents house to check everything the bike started misfiring on what feels like the right piston. It would cause it to stall out at idle. So i got it to my parents and startted checking for a vacuum leak to see if that was leaning it out. The one boot that connects the carb to the block didnt have a gasket in it, so i made a o-ring real quick put that in, but still didn't help much.

I'm thinking when i took off the gastank I may have knocked something loose that got into the carb and clogged one of the jets up. Tried messing with the mixture screws, but it didn't do much. Got the bike idling ok, but then when i was riding the bike would be alright then suddenly start surging then stall out.

Trying to find a carb rebuild kit for the bike now

You don't need a carb rebuild kit; just get the orings from Robert Barr (www.cycleorings.com) and the bowl gaskets from Z1 or your favorite Suzuki dealer

Does the 450 usually have an inline fuel filter?

[steveb922]

I don't believe so, but you may wish to check on a parts fiche.

After it stalls and has sat a while does it run ok then? Then start the missing and stalling over again?

[chris032188]

I'm looking at http://www.cycleorings.com/ website and seems like he only has carb rebuild kit for 80-82's not later years for the 450

Ya for the most part. The idle was pretty low - I dont have rpm hooked up so i can't say exactly, but it sounded like it was around 750ish - so I raise it up to about 1k.. The bike was idling better, wasn't misfiring nearly as much. SO I took it out for a ride go about three miles and the bike starts surging and stalls out. I shut it off waiting about thirty seconds and started it back up - road alright for about a block or two (had to keep out of low rpms) then it would start surging. I did this about 5 times until I got bike back to my parents house.

Prior to the valve cover replacement the bike was running pretty good ( a little lean) but wasn't bad. I'm thinking that when i was trying to get the valve cover off from knocking it around that I knocked some crud loose in the carb. Also the carb boot(not sure if im calling it the right name) that connects carb to the motor didn't have a gasket.

Shaking the tank while taking it off probably stirred up old silt. I would check the petcock screen and rinse the crap out of the tank while your getting the carbs rebuilt. Fully clean the entire fuel delivery system and put on new fuel line.
