That thing doesn't have some sort of compression release tied in with the kick start lever, does it? I've never heard of one on a 2-stroke, but I sure don't know everything.

cing31fan · 03-06-2007, 11:43 PM

were would it be located at because I never have heard of this before. Is it on the kickstart lever itself or on the case? But don't see anything connected to the lever. Have had the casing off and there is a spring around the kickstart dear that I had to wind up to get the lever to come back up to straight up and down; however I don't think this has anything to do with compression. Just there to bring the kicker back up. I really thank you so much for the help you have given to me threw all this and your post's have really been helpful.

Rickster · 03-06-2007, 11:57 PM

I don't really think it has one, I've only ever seen them on 4-strokes. If it did have one, you would probably see a cable running to someplace on the head.

bigE · 03-07-2007, 12:17 AM

Before you spend $$$ on a new coil, get a manual and test the one you have with a multimeter. If you think the kill switch is an issue, completely disconnect it. While your at it, check all the other wires to make sure there are no loose grounds and/or bare wires

cing31fan · 03-07-2007, 12:26 AM

True on $$$ coil. But yes not to worried about kill switch for know just really fill that possibly spark is were I keep looking. So all your guys help keeps my mind open to other things instead of looking at one area of the problem to long. Just lost because it really run like a champ when its running can the compression really be like that? Run Good after pulling it? Thinking more like it would run like #@$#@.. Once again your all a big help....

bigE · 03-07-2007, 01:11 PM

If it runs good after starting it, I would think the compression is ok.... Did you try kickstarting without the air filter on? (somebody probably already suggested this but i cant remember) Have you checked the gears and spindle that the kickstarter connects to? When you try to kickstart the bike do you feel resistance all the way down? If you take the spark plug out and put one hand over the cylinder head and use the other to push down the kickstarter you can get a good idea if the starter is engaging all the way down by how hard air comes out of the head.

Had similer problem once 2 stroke ran open or almost open great slow down the throttle she quit.Pin hole base gasket, coil gone won't run,food for thought,good luck ron.

cing31fan · 03-08-2007, 11:29 PM

BigE, Good ideas haven't heard about any of those yet. Everyone has been awesome help here so far. So I'm going to try these things. The kicker doesn't feel like resistance all the way down. Had casing off once because it was not kicking very well felt like it was jammed up. But didn't know why I took it off and put the spring loaded piece that lets the kicker up and put it all back together and It hasn't done that since...Its more a steady kick maybe a little stronger at first. However not a very strong resistance, to answer what you were asking. If I kick start it 2 to 3 times the engine will puff smoke out the exhaust like it wants to fire just not enough gettyup to the push. Hope you can understand what Im saying here...

cing31fan · 03-08-2007, 11:31 PM

metric sprocket, Not to sure what you are trying to say..? Please explain to my. Thankx.

bigE · 03-10-2007, 05:09 PM

Might try taking the idle air screw out and shooting some carb cleaner down the opening. I just did this on my 86 RM250 and it started much easier (probably due to the carb cleaner; i normally have to prime it) and runs a bit smoother in the bottom end now. Make sure you adjust the screw properly when putting it back in and run the bike so the carb cleaner doesnt sit and possibly ruin gaskets etc.

cing31fan · 03-10-2007, 06:41 PM

Will try that big E .. Thanks for all your guys help your awsome.

Message I'm getting,Bike has regular power at mid to high rev.won't start with kick start black smoke won't idle,Base gasket air leak or rings.popping the jug off you can check both gasket and ring .with the bike kicking the way you discribed,I'd replace both, cost 50 $ time 1hr set both carb jets at one turn for starters unless you have a manual it will tell you good luck ron

cing31fan · 03-15-2007, 08:29 PM

Placed the order for the parts so they should be here in a few days Metric sproket will let you all know how it goes..

eb77k · 03-16-2007, 04:20 PM

Coil probably isn't it. The stator on these bikes can be a problem. No spark or weak spark at low rpm may be ignition, not carburation. A piston, rings, and a bore aren't that expensive. A new base gasket would be the only thing you need to get the thing apart to measure and see if your friend was bs'ing about the rebuild. A weak crank seal can make them wierd too. These bikes turn huge rpm and a clogged exhaust, air cleaner, ignition problems etc. can jam you up.

cing31fan · 03-16-2007, 07:11 PM

eb77k, do you think I should just take it in and have it looked at or just keep trouble shooting it. The ring set I am getting has all the gasket's. Should I replace all them first before I try the ring set coming with it? Would love to figure it out so I have more know how on this bike. But its getting sunny and am dieing to ride it.. Let me know.

metric sprocket · 03-16-2007, 09:42 PM

Don,t forget to check that piston,and jug for scratches.luck ron ---and do it yourself pal you only have to learn once.

cing31fan · 03-16-2007, 10:42 PM

Sweet thankx, Metric sproket that was my plan just to make sure everything is all good.. And it will help me if I have other problems in the future. When I here a sound in a vehicle most of the time I can figure were and whats wrong just because Ive been working on cars for over 15 years. Didnt send it to a shop.

cing31fan · 04-16-2007, 12:59 AM

Whats up all? Well know I need to adjust the floats in the carb. I have gone threw and rebuilt the hole thing and it is very very fast. Know I can trouble shoot better because I know the hole bike. It was my first time building a water cooled bike pretty fun. So to answer my question.
