295 motor is in need of work where to start?
i've got a compression ratio of about 110 on my 1996 295 motor.
Trying to think where to begin to help build the ratio back up. Of course, a top end rebuild and bottom end rebuild is in the question but last resort. right now the motor is not smoking, its just running rich and uphills it begins to lag after a short time and begins to creep up the hill. i've started to check the valves, (4000) next i may clean out the clutches. (could that even solve the problem?)) after that??????? im lost..... thanks for any advice guys! |

Is that a workhorse? You may have a carb that is misadjusted.

Re: 295 motor is in need of work where to start?
Thats what I thought. I have a 94 804. I have about 110 in one cylinder and 80 in the other. I have the engine out now and I'm ordering a rebuild kit for 250.00 in a couple days. I'm going to do the 28 degree clutch conversion and move the exhaust exit to the bottom of the can. Good luck with yours.

Re: 295 motor is in need of work where to start?
Check valve lash.... I noticed you said you started it. Do that and recheck comp. to see if it comes up. If that doesnt work, youre lookin at a top end rebuild. A dead giveaway of ring failure is oil in the breather box. The only other thing is possibly an intake valve trying to pull through the cyl. head, in whick case adjusting the valves won't work. Either way, if adjusting the valves doesnt work, a rebuild is in your future.

Re: 295 motor is in need of work where to start?
.004 is what ezgo calls for. I set them at .006. Them seem to run better to me.
Check your rear clutch for operation. Take it apart and look at the risers and ramps. I bet you are aluminum to aluminum inside causing your issue. Rear clutchs last an avg of 5 years under normal conditions. Also check your linkages. make sure you have no binding. all cables need to move freely. being that old I bet you have a sticking cable. 110 is not bad, it is alittle low. I like to see 130+. I would run it until you need a total rebuild. you can run alittle hotter plug if you want. I have been known to run a NGK BRP2ES plug. The plugs are for the kaw engine and are hotter than the BRP4ES. |

Re: 295 motor is in need of work where to start?
Hello Courtesycart,
If you give more clearance, you get less power. The valves are open a shorter time. Really to much gives hammering / ticking and will damage the rockers and valveheads. I do not know what you are measuring in (inch?), but we overhere use millimeters (mm) I use 0.10 for the inlet and 0.15 for the hotter outletvalve. This was the same on my Fiat car engines This is done so on more than 100 race engines. On the GX 160, which my son drove as a little boy, to. Oh, on a cold engine. Benno |
