tzr 50/70

Hi there. After spending a month of working on my TZR after work I still can't get it working. I'll start from the beginning. On the way to work in the morning I was just doing 40 mph ( not revving the nuts out of it. ) and after I changed into 6th it just seemed to loose all power. I knew the engine was gunna die so I pulled in the clutch just incase the rear locked up. So I pulled to the side and just had a quick scan over it. It wasn't too hot, everything looked still attached and as if it should be working. I tried starting with the battery with no luck so resorted to bump starting, again with no luck. But it made no noise lick as if it wanted to start. There was no ignition of the fuel what so ever. I've cleaned the carb with help, changed the spark plug, tried new top end gaskets, but they were the wrong size. I've checked there's a spark but still no start. Has any one got any suggestions as I'm desperate to get back on the saddle

Hi there. I have a TZR 50 that's had a big bore kit put in, with new crank shaft. It was done after a previous owner blew the engine up. I bought it with the big bore kit etc and have ridden the very first mile it rode. I have a problem with it now though. I'm desperate for help and can't think of what else I could try. I have tried a fair bit and have spent some wonga on it. But it just won't run. Please help

Oh sorry. But yeah. Put a brand new spark plug in and the spark was pretty good. Can't think of anything else it could be.

My TZR wont start. Wtf is wrong with it. I have tried everything, changed spark plug, changed engine gaskets. Cleaned entire carb. Tried bumping and using battery, ( even though its flat). Tried everything I can possibly think of. It just won't start. And I miss riding it oh so much please help me.
