So yesterday took it out, before I left put in a new plug & mixed up a jug of 32:1. So I go out riding on the family farm, not running great, once i hit 3rd gear it falls flat on it face. I was running mostly 10 min runs with 30 min breaks. After about the 8th time, I go to kick it over and nothing, its not budging. When I put it in neutral i have no problem pushing it, and I can easily push it in 1st gear gear too. It wont shift into second or higher. I planned on completely rebuilding the motor and tranny sometime this year but wasnt planning on doing it this soon. Is there anything I should look for specificly now that may help me avoid doing a full on rebuild now? THANKX

sounds like maybe a trans problem if you can roll in first and wont go into any other.

pushing in gear should not be "easy"

never read about a problem exactly like this i guess... somthing new

Did you re jet for the change over from injection to pre mix?

Has a plug chop ever been done to confirm jetting?

Have you ever leak tested it?

Is there oil in the tranny?

 

[metron]

Honestly not sure I just picked it up last wednesday & all I realky did was clean it up and put in the new plug. Oil level looked good.

 

[Blaaster]

Every new acquisition of a used 2 stroke needs to be leak tested before riding.

It can help to determine why the bike was sold.

Often bikes are sold on by folks as they are starting to run rough because of maintenance neglect.

The little oil window often lies about the level, drain the old oil and refill with no more, no less than 650ml of oil.

That screams trans to me. I'm working on a KX85 with very similar problems.

Got around to taking the clutch cover off today. As soon as I took it off a broken spring piece fell out. Now with the bike is gear I can grab the clutch and it'll move so im assuming gears are not broken and not meshing. Still having a problem getting into 4,5,6. It will but just not as easily as 1,N,2,3. Is there any springs related to the shift forks or is the only spring in there off the kick starter? The service manual I have is kinda blurry and I cant really see from that & I dont have a clutch tool (on order) to take the clutch off to inspect behind the clutch basket. Thankx

 

[speedyslyder]

are you sure it is not one of the springs that holds the pressure plate on?

Ya. Pressure plate springs look good & clutch operates as it should. Metal piece was thicker than a clutch spring, similar to the diameter of the coiled spring on the kick starter.

Dug around a lil bit and found the metal kick start clip was missing so im assuming that was a piece of the metal I found in there unfortunately still looking for the rest of it. Im gonna pick up a strainer tomorrow & strain the gear oil to see if it was chopped up and is in there.

 

[tfaith08]

That KX85 that I mentioned a few days ago? Got around to it and found that it has a kickstarter assembly issue as well. Weird...

Good call on the strainer. It may take a few times to get everything out.

 

[metron]

Im assuming that the gears are hardened and they will eat up that spring if they haven't already. But id still like to get the clutch off to inspect the gears & case behind there & then brake clean the heck outta everything before i seal it all back up.

Do i need to put any type of sealant on the gasket or install dry? manual doesnt so say im assuming dry.

 

[bansheedave]

The shiftstar detent wheel has a spring on it also. Is that still there?

 

[speedyslyder]

they have magnetic drain plugs...If it can help you sleep at night

 

[metron]

YOU GOTTA BE KIDDING ME!. So I fixed my initial problem (kick starter clip was broken) get it all buttoned up and go to kick it over and..........No compression, nothing! I dont mind putting in the wrench time but come on. Im new to the whole atv & 2 stroke world so im guessing im gonna be doin a top end rebuild?

 

[Blaaster]

It is a shame that I could not have told you to do a leak test before you ride a used 2 stroke.

The PO possibly sold it knowing that it had a problem and was not sure what caused it.

Leak test to find our if indeed it is air tight before you pull it apart!

A 10 minute ride on a leaky engine is enough to destroy a top end, at any speed or throttle opening.

 

[metron]

New top end it is. Got ambitious pulled the cylinder & found half the piston skirt missing.

I know the correct/through answer is going to be "split the case and get it all out". But is there an easier way to do it?

 

[Blaaster]

In a word.​

"NO."

But there is a better way to do it,
replace all bearings and seals.​

Pay someone to do it for you.
