TRI-Z not running PLEASE HELP!!

[Groundworx]

I am rebuilding my TRI-Z. I am basically finished. I just have a few minor things to take care of. Here is the deal. A few days ago I got everything put back enough to fire the bike up. I kicked it over and it ran for a couple of seconds and died. I didn't have the fuel hooked up to the carb so I knew it wouldn't run long. I put a little fuel in the cylinder and fired it again. It ran for a couple of seconds and died. I continued putting the rest of the stuff together. I got the carb hooked up, air box on, and all of the cooling hooked up. I tried kicking it over again. It didn't even try. I thought I might have gotten a fuel line on the carb hooked up wrong. I double checked it and everything seems to be good. I tried to kick it again and the kickstarter was extremely hard to push down. I kicked it over a couple more times and then gave up for the night. I went out the next night and it wasn't hard to kick over anymore, but still not trying to start. I poured a little more gas in the cylinder and still nothing. I checked the spark, and it is there. I even believe it is gettting fuel. I can smell it at least. Is there something I am over looking? I thought it would have to run for a couple of seconds at least if I put gas in the cylinder. Please help....

... Try a little ether or hotshot directly into the sparkplug hole and close it up right away next time you try it ... sometimes rebuilds need a little help to get them going. I'm ofcourse, assuming you have the fuel pump hooked up and it operates, and you have checked for spark.

[Groundworx]

I do have the pump hooked up and I have checked for spark. I just put a teather switch on it and I even pulled the switch to make sure it wasn't firing when pulled. Everything is sparking. I do have the fuel pump hooked up. The only thing that runs the pump is that vaccuum line isn't it?

[edog]

There was a vaccum tube that came off the carb.It was pinched,causeing it to start running for a few seconds then die.It was flooding the carb.Hope i was helpfull

[Wickedfinger]

The vacuum tube DOES NOT come off of the carb and plugs into the nipple on the port hump of the jugg.

[J.D.]

Take the supply line off your carb and see if gas is squirting out. If it is, your set. It took me about 20-25 kicks to fire up my new top end, with an empty carb. Good luck to you.

[edog]

there is a vacume line.There is differences between the two. :o

[Groundworx]

The vaccuum line does run from the bottom of the jug back to the fuel pump. My vaccuum line is hooked up. Fuel is getting into the carb. I am not 100% sure fuel is getting into the cylinder, but after I kick on it about 5-10 times, I can smell fuel. I am not sure about any other vaccuum lines. My TRI-Z wasn't exactly done right when I got it. There were some lines that were plugged up with different things. I did put a different carb on mine when I did the engine. I am confused about the fact that I can put a little fuel in the cylinder and nothing will happen. Like I said, I had put a little fuel in the cylinder earlier and it did fire up a for a few seconds. Is there anything that I might have done or not done when I put the top end on that could cause this? :confused:

Do a compression test. I am kind of concerned that maybe something happened when you tried starting it the first time and you couldn't kick it over. but, if your getting fuel and spark, compression is the only other option. also try using a brand new plug. I worked on a dirtbike for my nieghbor once and that trailprotrailprotrailprotrailprotrailprotrailprotrailpro had great spark, but wouldn't start. put a new plug in after ruining a pair of work boots, and the thing fired right up. i guess the problem turned out to be a weak stator. good luck

[Groundworx]

I don't have the stuff to do a compression test right now, but I did put a new spark plug in it yesterday. I am going to go up to the local shop and see if he can do the check for me. It does appear to have good compression though. I was wondering if something might have came out of timing. I don't know much about the TRI-Z. Is there anything that could have came out of timing when the kicker became hard to kick over.

[Wickedfinger]

Ok well, I still thgink you should try some ether like I said - I had the very same problem with my Z after the rebuild and it fixed it but .... heres a couple of things to check - make sure the choke isn't stuck closed, check the pilot screw, make sure its not seated, check the pilot jet for clogs, could be an air leak, might have a bad CDI or trigger coil/pulser or the timings way off. Good luck.

Get somebody to hook up a tow strap and pull you to get it started initially. There are lots of reasons it may be hard to start after working on it, but most of them disappear once you get it fired up and running the first time.

[Groundworx]

I am going to try the ether first. If that doesn't work, I will try to pull start it. I am worried that Cliff might be right. I am afraid that something went wrong when the kicker got hard to push down. It doesn't make sense that it would fire at first with a little gas in the cylinder and now it won't. Does anyone know anything about the timing on these? Like how I could check it?
