Roketa 150 Kickstarter stuck, engine won't turn over  By  johnathonkreider (Read 3,098 times)

If its a 2t non oil filed cvt cover pull it off the gears between the starter and kick are probably pitted get a trianglar file and file the teeth make sure you re lube the start/kick pinion where the starter comes in at the block should look like a cut short pill bottle with teeth if you press it with your fingers it's kinda spring loaded.


Had mine get stuck on my 07 ruckas tank engine

I didn't understand what that meant, I could follow that sentence. Would you mind using some punctuation so I can follow what you mean? I'm confused with what you said.

Some guy I know said it might be seized, because it's been harder and harder to start, it wants to die whole idling, and because the Kickstarter is now jammed, and all of that has happened over the last few days. Is there any truth in that? If so, what can I do?

I will be doing my best to adjust the valves, check and replace the oil, and look at the gear box today.

Okay, so I tore apart the top end and looked at the valves. The exhaust valve wouldn't move a bit. I unscrewed the valve adjustment nut and threaded cylinder thing, and as I tried to manually move the cam with a wrench (the same way you would adjust it to TDC for a value adjustment), I got to a point where it wouldn't turn any farther. Same thing if I reversed it, and tried to go counter clockwise.

I called up my dad and he thinks that the exhaust valve stem decided to break off or bend. Not sure what to think: what are your ideas? Literally anything can help.

Oh my goodness, like talking to a wall...

As I said before your transmission (CVT) is seized... Now explain to me please how you think the engine is going to turn when the output shaft is jammed??? You have to rectify this problem before attempting to work on ANYTHING else. Ignore the valves until you can turn the engine fully, the valves never go out far enough to seize the engine or cause damage to the piston. I recently had an issue with a valve sticking out all the way and it did not make contact with the piston at any time even though it was more than fully extended, bent, and jammed with a foreign object...

Simply remove the CVT cover and remove the kickstarter gears, you don't need them in there if your electric starter works and it's a heck of a lot simpler than valves. Also if your not at TDC then your valves will be in play, so of course they will be "tight" and not be able to move because they are currently pressing down on the valve...

Ask if you need clarification.

Alright, well I just say that because I have basically been saying the same exact thing the entire time and you haven't asked for clarification and it feels as if you aren't comprehending what I am saying and just moving on instead of asking.

Are you sure it is not moving, can you show us a video with sound? Is it just that the engine may be too hard to turn by hand (compression on 150cc scoots are generally too hard to turn by hand, use a socket wrench on the flywheel or end of the variator/output shaft to turn it), or does it feel as if it is tapping against something, or does it feel and sound like it is scraping something?

It may be possible it is still jammed but only at a certain point in rotation getting caught and rejamming (which happens with kickstarters with chewed up gears, can even engage while you are riding and cause a complete failure of all transmission parts). As I said; remove the kickstarter gears if they are causing issues, you can use your electric starter instead. Literally unscrew/remove the CVT cover, and with yoru hands, reach in, and gently pull the gears out, it's just that easy man.

I do hope you have a gap feeler set for the valve adjustment, sounded as if you did not, which will cause it to not run as well if adjusted without. You should not be just unscrewing valves... You should have measured the gap at tdc first, then unscrewed and keep measuring them and adjusting them until you get them to recommended settings. But don't worry about the valves until you can figure out why the engine is not fully rotating.
