My shee has been acting funny lately, like 1st gear bogs down and does have much throttle range. I just went out to start it and when i kick it over nothing happens, it doesnt even sound like its close to starting. I just recently replaced the reeds and when i was putting it back together i put a little bit of gas in the carbs to help it start and it started fine then but now 3 days later it wont start. Is it the head gasket and theres no compression? and it has been overheating lately, does that go hand and hand with the head gasket going bad? :cry:

pull the head off and have a look around. if you have been over heating alot you my have burnned a hole or mellted a piston. also have a quick look at your water pump impellar. mine over heated and melted all the blades off of it and then i melted the pistons. first off does it feel like it has compression when you kick it? do a quick spark check before you tear in to the engine.

:lol:

It feels like it has a little compression, but not enough so it must be the headgasket. Quick question- before i pull off the cover to the water pump to look at the impeller do i have to drain the coolant?

not at all , it will drain all over you .... :jesterlaugh: ......

 

wierd you did all that and it still wont fire up , check if reeds are broke ? or if your carbs are dirty. NEXT question i have and maybe i didnt read properly is if your bike was running fine and you changed your reeds and worked in the intake section how would your compression just goto shit ? unless you have a air leak or something...... shit i dont know man give her a good ol look down & compression test ......

Check spark for sure. Ya don't want to replace parts if not needed. If you removed the throttle cable from the carbs did you resync them???? Need some more info to assist ya better.

Chase, go blaze another man :lol: . He replied to my post and said it didn't run. You can check spark and make sure, but def. do a compression test before you start tearing into her. If you take that head off, you need a new head gasket right off the start. It does not mean you have a blown head gasket if your compression is low. That is the last thing I would be looking at now. If your reeds were trashed, there is a good chance there is a chunk, or a million chunks of metal loose in there. Do the compression test first, could be a 100 things wrong, need to eliminate some things first.

Figure (depending on your altitude) about 130 or so new.

 

Less than 100 and it's time for rebuild, taking into consideration there's no leaks in gaskets, etc., or...if one cylinder is more than 10% more/less than the other.

 

This figure is for sea level type elevations. Compression drops about 5 to 10lbs roughly for every 1000 feet or so.

to check impeller you should drain coolant. but your still probably goin to spill some.

 

Last time I had the clutch cover off and check it after I drained coolant it spilled inside the clutch area and I had to clean it all out. I did drain it first though heh.

Ha, im sorry... Right before i replaced the reeds i checked the compression and it was at 125 in both cylinders, i wasnt sure if that was normal, high, or low. After i installed the new reeds i put a little bit of gas in both carbs to help it start, after it was all back together it started on like the 8th or so kick and it ran good. I took it out and rode it for about half an hour the next day and when i went to park it, it had a huge cloud of smoke coming out of the radiator. I went to start it about 2 days after that and when i kick it over it will kick but it wont start. So now im at a loss of what it could be :confused:

125 should be fine. You might want to check it again to make sure you still have 125, soulds like you overheated and boiled over. You need compression, fuel, and spark for an engine to run. If you have spark, we are pretty sure you have ok compression, fuel is not getting there. Clean your pilot jets. When I say clean them, I mean take them out, blow compressed air through each pilot, and make sure you can see light through them. Make sure your float bowls are on the correct carb when you put them back together. In the bottom of the bowls they are labeled 1-1, and 1-2. 1-1 goes on choke side carb. If not, choke won't work properly and you may kick it over 15,20,25 times before it will start. If you did indeed boil over, you should change the coolant and figure out why it overheated. Are you jetted right, impeller intact, maybe just haven't changed the coolant in a while.... Let us know what you find after all of this.
