No Compression

[blowfishct]

Took out the 200x yesterday It has a fresh rebuild went to park it and it stalled out. went to start it nothing. Tryed to push it and it started and then stalled out again. went to kick it over and nothing I could push the kickstarter by hand. The worse thing is I just put a clutch in it on sat. Thanx for any help Bob

your timing chain could have come loose, or a valve stuck,,,,pop the rocker covers off and kick it over see if the valves move, if they dont its your timing chain/ tensior possibly....

[blowfishct]

Thanks as soon as I get done work I'll try that.

[chris200x]

OH
NO!!!
I had no idea it even needed a clutch! Did you run a compression check? Couldn't even guess what's wrong. :(

I don't know if it matters but did you break the engine in properly. I hope I told you that it wasn't broken in yet. :(

Dont panic, its probably a stuck valve, thats not uncommon in a 4 stroke. Crank it over slowly and watch the valve train move. Only takes a tiny bit of grit in a valve stem to do that and it may work its way out. Once saw a 4 cyl Datsun that had a stuck valvetrain and sounded like a shotgun when it went, then it ran fine!

[blowfishct]

I took it easy with it for the most part I could not run it wide open 5th gear is not right. It will go in 5th and jump in and out.

[chris200x]

Well like I said I never got to drive the thing so I really did not know about the clutch. I really hope it's nothing major. Like stated before the motor was just rebuilt. I put a timing chain and tensioners in there myself so I know they are new for sure. That little trike is lucky that that didn't happen to me after I put all that time and money into it. I would of throwin a match in the tank and burnt it up right were she sat! :lol: :TrikesOwn

Highly unlikely ^^ but TG0 is right, pull the valve cover caps and see if everything is moving. If that's all moving good and vavles are adjusted right then it's probably time to tear it down and see what's casusing it.

[cragster]

i had a atc with a stuck valve and i pulled it around with my 4 wheeler and poped the clucth and it unstuck itself...had no compression before

[slothminx]

TG6 if the valve had a piece of grit holding it open wouldnt it come off as soon as the valve was moving a bit more open and closed again? if it was stuck open very far. there would be a case of piston hitting the valve :eek: . nope my bet is that its slightly more serious than that and you can get a good idea by taking the plug out . Has it been running rich or lean? if its lean you may have holed the piston :cry:. if it was rich thats different. You may have a stuck valve or youve lost part of it . when you have the plug out turn the engine over and feel for air blowing out the plug hole. if nothing its pretty damn serious . if you got air its time to have the head off and check out the valves, if all looks good you might have broken a ring pull the barrel off carefully and check them out . loss of compression that serious is not good. Did it make a noise when it stopped or nothing?

Ahh ha! i believe it was running lean because the carb needed to be rejetted! Did you ever mess around with the carb Bob?

[blowfishct]

To answer sloth it made no noise it just shut off. I can push the kickstarter over by hand and here the piston goning up and down and the I can here and fell air coming out of the pipe. I cant get the intake valve cover off but I tride to flood it and no gas in the engine could the intake valve be stuck? could it have jumped time? And chris I adjusted the carb and was running fine not rich or lean. I still have the kx500 I'm thinking super trike 500x little honda and a lot of kawaski.

[chris200x]

I hope you never have to take that intake boot off!

" I still have the kx500 I'm thinking super trike 500x little honda and a lot of kawaski"

Lol'.... Do you have a red cape you can wear! :lol:

[honda200]

you put the clutch in, is it possible that the clutch is still engaged?

I had this happen when i put a new clutch perch on my Kawasaki S2 motorcycle, the clutch perch wasnt right for that bike, so it pulled really really hard on clutch cable and it actually made it seem like it had no compression, i could push the kick start down with my finger, i couldnt think of what was wrong then finally i yanked the perch off and she regained all its compression!

so, maybe its a simple fix, dont go too far into the motor without checkin little stuff first ;)

[chris200x]

I winged it when I installed the new clutch cable. Both nuts are/were/might still be on the same side toward the front. I did this to pull the cable tighter. There was alot of slack but I never ran it to try it. When you came that was the first time I seen that trike move under it's own power! :rolleyes:


I bet your wondering how I'm still taking pictures? :D

[blowfishct]

I pulled the motor off the bike and then I pulled the head off and found a stuck intake valve. But the best thing is the valve stuck and hit the piston and bent the valve so rebult time.

[slow200s]

ouch
thats no fun and just after the other rebuild right? that just not fun
hope this time you have better luck!

That sucks. Oh well, that gives you an excuse to put in that kx 500 motor. :twisted:

[chris200x]

Yikes!!! :( What are you gonna do? I'm not too good with those but is there alot involved? Btw That's the 5th time that motor has been pulled.

[blowfishct]

Well I guess I'm goning to rebuilt her I have to split the case first and check out 5th gear it goes in gear and than sounds like it is slipping. Does anybody know were I can get aftermarket valves? And I would like to thank everybody for all the help. And chris no its not that bad pulling it apart it's going to be hard messing with the trans.

[chris200x]

I tried to change the tranny gears in that motor myself... They were chewed apart and the motor was locked up when I purchased the trike. Those are newer gears in the (not original) Anyway, I was in way over my head. Be sure to use the manual and keep everything in order. I left the gears on the workbench for a while and everything got mixed up. :rolleyes: A good digital camera is a good idea! Take lots of pics and use them for a reference. It's very hard to tell the diffrence between gears from the schematics in the clymer manual. :rolleyes:

The only other thing that I can think of is the guy that had it before me took the motor apart... When he put it back to gether there were some things missing from the motor. Like a couple circlips and washers... Make certain that all the shims or washers are in with the gears.

Oh, denniskirk and rmatv both have vavles available to the 200x. ;)

[blowfishct]

Thanks chris I ordered the valve from dennis kirk $20.00 no to bad I will keep you possed to what is going on.

[Somekindofjerk]

Redneck ring test-put some 30 weight oil in cylinder, enough to cover piston head, put finger over plug hole and give it a pull if your finger blows off or you feel more preasure than without the oil your rings are bad, if it makes no difference your valves are probably missgaped. Valve lash is easy to fix you just need gapping specs. Valves are checked and gaped through the valve covers, large round 22 or 24mm head plugs that cover your valves, heck a valve could just be stuck or your timing could be off. Timing is easy to check to, remove timing plug and when piston is tds the t should line up.

[chris200x]

Hey Bob, You will need to pull the flywheel in order to split the cases. Which requires a puller. I don't know if you knew that or not but you'll have to get one of those. If you got any shops around they will do it for a couple bucks. That's how I pulled mine. If not they can be found in the same place you got the vavles for around $10-$15.

[sblt500r]

i have to ask, how would a valve just stick after its been run for awhile?

sounds like it was out of time and thats why it was hard for you to start in the first place, chris.

[blowfishct]

I dont now why it stuck a valve but it was stuck and its bent. Can I get away with out putting a new head gasket in it? And Chris my dad has a dump truck co. and has every tool in the world I hope. I really dont want to split the case but if I cant get it back togather its looking like a Honda 2 stroke 500x death trike!!!!! Hey there gose Bob that red flash the only thing in my way will be trees.

[OldSchoolin86]

Of course it's gonna be stuck after the piston hits, bends, and rams it up. Get a new head gasket, you might make it work again for a while but you wouldn't want members thinking you're hacking things up.

[sblt500r]

thats what i'm getting at. the engine must have been out of time for the piston to hit a valve and bend it. and you should always use new gaskets. its cheap insurance.

[blowfishct]

will do thanx. Also if anybody nose anything about the trans in a 200x it would be helpfull.

Valve sticking is common in 4 strokes. Here in Iraq I had gotton a brand new pressure washer for the humvee's. It worked fine for 3 days and then just shut off. I tried putting gas in the cylinder and everything to get it going again. Checked the spark and everything was fine. Then I realized that it was a little to easy to pull start. I pulled the valve cover off and sure enough the intake vave was stuck open. I took the spring out got a wrench and pulled it back and forth a few times and it got free again. Put it back together and it started right up. Thankfully nothing bent. I couldn't understand how it happened, it was brand new. Well good luck with the rebuild.
