Could my engines already be swapped ??
I bought a Yamaha G11AK utility cart for really cheap and it didn't run at all, I cleaned out the carb and fuel pump and tank, installed a new electric fuel pump and changed the oil and installed a new battery and it started right up but it smokes pretty bad. I then did a compression test and it pumped right up to 205psi but then leaked down pretty fast so I took the engine out and opened it up and found the valve guide seals to be leaking or so I think. With the compression tool screwed into the spark plug hole I rolled the engine over for about 20 or so seconds and then when I took the engine out there was about a tblsp of oil on top of the piston, also there is like a clean trail on the exhaust side of the head between where the valve seats and the guide (kinda hard to describe) The exhaust valve is on the right hand side and you can see the clean spot im referring to in this photo:
My question is that on the engine block it says its a JN5 300cm3 so will G11 parts fit or is this not the original engine and I have to get JN5 parts. I'm pretty clueless as to what parts will work with this cart, I just want to be sure to order the right ones the first time LOL !! Thank You for any information you can provide !!! |

Yep, we (Cart Service Equipment) built that. We had a custom aluminum top frame built for those and a (PNW only) wrap around windsheild. Don't break the windsheild...they retail for 400.00 now!!! Where you live Robodad?

So I decided to get another one but wanted a gas one because those batteries are far too expensive to buy again, opened up CL and there it was super cheap and the guy said he had his mechanic look at it and couldn't get it to run so I took it home and cleaned out all the crystalized crap out of the fuel system and tore the carb all the way down and cleaned every piece and put it all back together and new fuel and filters started right up and ran fairly good but smoked really bad so now I am in the process of doing the rings and rod bering etc... just to see if it will quit smoking. So thats the extent of my golf cart career LOL !! so I'll be askin more questions for sure !! Oh I just got another golf cart last month its a Hyundai and put a new controller and F&R switch in it today and now it works really good, not sure if I should unload it now that its working or just hang onto it since I replaced some of the more expensive things.

Re: Swapping engines/G2/G9/G8/G14
Been reading but skipped over some of this thread. I was trying to figgure out what the output shaft size is on the jamaha motors. I have a bad motor available and need a variable drive pulley for a horizontal motor I haven't picked out yet. It's for a cc carryall that I'm converting to gas. I have the gas rearend and driven pulley and some of the other gas cc parts but no drive cvt pulley. If I have too I can get a machinist involved but I bet it is easier than that.
I know search, but I didn't do too well. Charliew |
