1993 KLF300C bayou gasket issue

Recommended Posts

Hi everyone,

Just looking for some advice on a Bayou 300 that I am working on cleaning up and rebuilding. I bought the beast for 200 and am going to be into it for about 1200 all said and done. I decided after changing the oil three times in just around three hours of driving and having it come out completely black that something was up. That and the clutches were slipping. I believe now that the previous owners had not used the correct oil for the wet clutch system. Both were toasted and nearly metal on metal.

Anyway, when I started opening it up I realised there was a massive amount of sludge and gunk inside so I decided to crack open the crank case as well to clean it all up nice while I had the motor out. 

This is my question now, I cannot for the life of me find a gasket any where that is for between the two crankcase halves. Is that normal. There was gasket material that was between them originally that would not be reused. Can I just use a gasket maker like ultra black or something of the sorts or am I best off to get gasket material and painstakingly cut out all the shapes and lines and get a gasket made that way?

Or does someone know where I could get a gasket?

Thanks in advance everyone.

Byron

It's not uncommon for case halves to not have a gasket.  Your Bayou is one of them.

I use Threebond 1184.  Just a light coat on one case half then assemble.  Make sure both surfaces are cleaned with brake clean before applying.

Each manufacturer has their own case sealer also.  Yamabond 4 is a good one.  Suzuki, Honda & Kaw have theirs too.

I'd stay away from silicone sealer although it can be used in a pinch. The mistake guys make is using too much.  It gets into oil passages and blocks them.

Thank you for the info wanrep. I ended up looking through the service manual and finding that it said to use liquid gasket. I guess I should read the instructions first... :)

I will look up that Threebond and give it a go. I'll try and post some pictures too.

      Hi there
      I am in need of a manual for my KLF 300 Bayou 4x2 . I've found others on here for the 4x4 model, but was wondering if I need a separate 4x2 manual. Does anyone know?

      Several months ago, I finally got around to fixing the bayou. Rebuilt the carb, replaced the fuel selector switch, hoses and fuel filter, and she ran great. Only had 2 minor issues since then where, at higher speeds, it acted like it was choking out when I let off the throttle.
      Lately I've noticed if I let it go for more than a week, it almost drains the battery dead trying to start. I initially thought battery, but after inspecting I found very little if not any fuel flow through the line until it starts and runs.
      I'm a little baffled and don't have much time to mess with it as most my free time right now is spent on getting my rv up and ready for hunting season in the next 3 weeks. So any help on quick diagnosis checks would be helpful. Otherwise I'll just keep starting it every 3-4 days to keep things primed until I'm done hunting.
       
      Oh, and another question on a different topic. Does anybody know what the mounting brackets on the front rack are for? I'm referring to the 2 angled metal tabs with threaded holes that are located on the left, near your knee when sitting on the quad?

      posted a while back - it was running at one point - I have all the plastic shroud off - it's down to frame and engine now
      -fuel pump: when line from petcock is attached, no fuel comes out other side to carb; the line to the carb is open (can blow through it); I thought when I cranked engine that the pump would spit out fuel on other side but it does not; I removed fuel pump and opened it up - diaphragm looks good - but internal areas had lotsa calcification build up - I cleaned this out and dried it good - the clear plastic pieces (?diaphragms) aren't broken - the spring w/ steel ball on end moves freely; am putting it back on tomorrow; but can anyone answer about the pump? isn't it supposed to pump fuel through it... to other side... to carb? puzzling
      -along with fuel pump: I replaced petcock 3 weeks ago (gas tank had rusty fuel in bottom - cleaned it out prior to new petcock); when I turn petcock arrow NOT to on or reserve, fuel comes out of line; when I turn it to on or reserve, fuel doesn't come out; puzzling
      -I don't know what's on back of fuel pump - it's a valve that has a hose coming out of it - looks like it goes to engine/carb - I haven't traced this out yet - what is it?
      -can squirt gas on air filter and engine will run for 2-3 seconds then stop - fuel in top of carb (under diaphragm) does same
      -it likely needs carb rebuild - will get to this - but something isn't allowing fuel to get from fuel pump to carb
      -I THINK it has a mikuni model x carb - diaphragm is ID 26mm  OD 68mm - hard to find inexpensive diaphragm, I guess because it's a model x
      -last thing - I replaced solenoid due to old one clicking; I HAVE to be charging the battery or it won't start/turn over - battery just goes dead; but if charging, it'll turn over nicely; i'm guessing it's a bad battery
      -any help appreciated - I've never owned an ATV before - inherited this beast from grandparent in-law

      Hi guys new to this forum and thought I’d jump on as I’ve just bought my first quad a Kawasaki bayou klf300c 89 model. It had starting issues when I bought it so I’ve gone thru and replaced the cdi, voltage regulator and starter solenoid aswell as rebuilt the starter motor after all this it was still free spinning on electric start so I pulled the stator cover off to find the fly wheel wasn’t spinning so replaced the one way clutch bearing put it all back together and still not engaging at all. I’m at a loss and looking for some ideas on we’re to look next to solve the problem
      cheers Ben 👍
