Just recently purchased a '94 Polaris 750 sl from a guy and it has an issue with getting up to speed, it wont.
The max speed I can get it up to is about 30mph.
Compression is 130 across all 3 cylinders. It's been rebuilt in the past by someone.
It has the aftermarket fuel pump that splits into three separate lines.
It also has aftermarket flame arrestors.
It seems to vibrate a bit, and the idle is a bit high, it didn't idle as high as it does until I took it to a shop to get checked out and it had this same issue before then.
My guess is a vacuum leak.
The shop I took it to replaced the nozel that was on it with the correct nozel (previous owner replaced trim nozel with manual nozel that angled downward), and he found that the engine was not completely bolted to the plate that connects to the hull so he pulled the engine out and connected it to the plate securely and put it back in.
The guy at the shop said that the jet pump looks fine, and a visual inspection shows no gaps between it and the wear ring but could it be the culprit? What else should I consider?
Thanks in advance for your help.
