I have a 2006 Suzuki ltz400. i bought it off some kid upstate and it ran when i tested it at his house. i brought it back to Long Island then it wouldnt start. it doesnt electric start to be more specific. Itll start if i pop the clutch in first gear but it doesnt idle, it dies. only does this when the motor is cold, when the motor is warmed up, itll idle. so i took it apart the i found that it had a blown headgasket. i replaced that and now it still doesnt start. i checked the timimg and its TDC on the bottom and top. now it cranks very strong and the compression is strong but it still wont turn over. its popped a couple times but it doesnt run. i cant seem to figure it out, i need help please.:mad::mad:

is the spark strong? have you tried a new plug? don't replace with the plug that's in it, it might be wrong. make sure it is right one for the bike. ngk has a good chart for atv's ...

yeah i got the manufactor recommanded spark plug. it does have spark.

do you think it's a fuel problem? motor needs fuel, air and spark ... if it's getting good fuel supply, the carb might be somewhat dirty. seafoam is a good fuel additive and it'll save you tearing the carb apart ...

it seems to be getting fuel, air and spark. the carb was also cleaned out. rejetted and carb cleaner.

What are the compression #s... If at a total loss and willing to have it repaired bring it to Diggin Racing in Bohemia. Chris did excellent work to my motor. Highly recommended

Hey guys thanks for all the help, it was the valves. The intake valve lash was at 0. I didn't realize how important the adjustment was the valves. I'll give you guys an update when it fix it. I'm waiting on parts now:wink:

My intake valve was really tight. 0 valve lash clearance. I think that's the problem, I'm waiting on the DRZe kit and Ferrera valves then I will replace the old parts. Thanks for the help guys ill give you an update soon

      Hey everyone looking for a suggestion of where i can start looking. But first I'd like to explain what happened. Took the bike this morning got it started in 6 degrees celsius in 6-7 kicks? No choke. Drove 6km and when shifted to next gear bike decided to just shut off, stopped checked everything out seemed good, started first kick and on i went, drove maybe another 2km bike did same thing but this time it took me 10-15 kicks to get it started, on the third time after a kilometer decided not to start at all. Kicked it like a 450 a couple hundred times, nothing. So far checked gas is good, bypassed fuel filter and on/off valve to eliminate that problem, hot wired the kill switch in case something got corroded there. Nothing. Any suggestions would be welcomed. (Heard valve adjustment are a must do?)

      I been working on this thing for like 2 months now and it will not run right, is very smokey, and has a pretty loud tap that i think is in the bottom end. Not sure how much the parts are but i will put the time into it if they are pretty cheap. Im not very experienced but going off how the plug looks and the oil on top of the piston i am getting a whole lot of oil coming in from somewhere, not sure if it can come from the valves or if the rings are just shot, my cheap scope cant really see the walls of the cylinder too well.

      Do not know what else I need to attach the pull start to this machine. I have the pulley but nothing to attach it with. Could you help with what else I need. It's a 1999 Lakota 300

      Pulled my '86 Moto4 out of shed where it sat for 20 years. I knew it smoked. checked it over a little put in gas and it fired right up!! 
      Drove about 100 yards, ran about half throttle wouldn't idle.  Put on somenew parts, jug/piston and rings, carb and valve seals.
      'went together ok, tuned it over by hand about 6 revs whick went well. Hit the starter it fired for about 6 revs and quit. tried it again fired once and then th sound of something slipping like maybe chain slipping over spoket.
      Took cover off to watch cam sproket, hit starter again, heard same noise and the cam sproket was not turning but jumping a bit. Chain was still tight. You will probably tell me I need to split the lower case but hoping there mightbe something else.
      I don't fully understand the chain tightener, the plunger only moves about 1/4 inch, should it move much more than that when off the motor and compressing it by hand?
      Thanks for any thoughts.
