2007 ezgo st sport no power under load

grandpa1 · 09-02-2014, 07:48 AM

Good morning BGW friends. I am having a problem with a st sport2 I just bought. It runs great on flat ground but when I put it under a load or up a hill it losses most all it's power. The motor was just rebuilt like a month ago. I can't figure out why it is doing this. Could it be the clutch? If so how would I check that? Any help would be awesome. Thanks

Probably the clutching. Can you make a video of it shifting up on blocks?

grandpa1 · 09-02-2014, 09:32 PM

Yes I can do that. What am I looking for it to do exactly?

I would try to get a video of at least 3-4 full shifts from idle. That may give us an idea of what is going on. Make sure to get both clutches in the video at the same time.

Hey sorry I have been out of town for a while and I am just getting back to work on this cart. One thing I found so far is the front motor clutch was going bad. I have replaced it and it seems to run a Lil better but if I back it down in a small ditch it still will barley pull it's self out. Motor lugs way down . I ran it through a few neutral revs and the front clutch closes up almost to the top and the rear clutch seems to go down pretty low. What else should I look for?

I will try the video thing if I can figure out this phone.

Anyone?

well if your rear clutch is not set for torque or is worn the clutch can open to easily and hence the sluggish movement , also these can barely get out of their own way to begin with in stock form with a stock engine , you may want to consider a 28 degree clutch upgrade and torque spring
