2007 Suzuki LTZ-50 Won't Move. HELP!!
I bought this LTZ-50 for $50 and it didn't run.
I changed the oil, ultrasonic cleaned the carb, new air filter and now it starts. The idle is high and I have not been able to change that with the throttle stop screw or the air/fuel mix screw. It smokes a white smoke and it won't move. I am not sure if the belt is stretched, clutches are bad, drive shaft and counter shaft are stripped. I really have no clue. Any help would be great I am sure it is something simple but I am stumped! |
Does the rear wheels spin if you pick the rear end up?

I'd start with taking the clutchs off and inspect. See if there is a roller problem.
Then maybe motor? Valve adjustment possibly or compression??? |
I am going out to the shop to take a few pictures of the roller, cage and plates. I will also readjust the valves and check the compression.
What should I look for other than flats spots on rollers? |
I adjusted the valves correctly IN .003in and EX .005in at TDC on compression stroke--right after the intake valve closes.
I got a compression reading of 60 PSI. The spec says no lower than 114 PSI and standard is 156 - 171 PSI. This would explain, I think, why the clutch won't engage and why the sparkplug is black after running for 20 minutes total. Does anything look out of sorts on the clutch? It seems as though I am headed for a top end rebuild. I have not found any oversize pistons or rings for this model. Do you know where I can get these parts? |
The front clutch seems fine.
Suzuki doesn't show oversize pistons. That usually means that the cylinder is nikasiled (hard plated) and you don't bore those. You might want to call a Suzuki dealer on that. If no damage is done to the cylinder wall, a new piston/rings should do it. I recommend Suzuki parts. |

Yes, no compression, no power. These 50cc 4 strokes have so lil power in the first place.
Far be it for me to argue with the dealer...but, After ripping all that apart, don't it make sense to put a new piston in also?! I think pistons wear too. |
