Final update. Pulled the twin out and removed the sump. The conrod remains were in about ten pieces. Went with the 18HP from Dave in Charmhaven. After tapping the mounting holes it bolted right in as luckily the chassis is double drilled for the V twin or a single B&S/Honda pattern. The plug on...

Took out the plugs and run a compression test, 120PSI on one, Zero on the other. Using a very bright torch peered through the hole in the crankcase, there is only one con rod attached to the crankshaft, just a shiny spot above it where the other one should be. So I guess either the big end bolts...

It is barely running, will start eventually but rough as. If it did break a conrod, depending where it broke, e.g., close to the big end bearing, it would be possible to still run if the piston was up at TDC I guess. I guess there wouldn't be that much of a problem of power down size for a new...

I obviously knew it was a V Twin, otherwise it would have been pretty bizarre for me to be posting about it running rough on one cylinder. What I was asking was what people thought about dropping it back to a single cylinder engine given that a no name 20HP twin is about $1400 whereas a single...

Yes, I'm thinking so. Even if it is something else that caused the hole though it means replacing the engine doesn't it? Due to cost though I am wondering if it is worth it to go with a new V twin or maybe drop down to a single cylinder job around 18-19 HP for less than half the cost. Thoughts?

Well guys, the heat finally stopped, then the rain started. At last it is a sunny cool day up here so all fired up with all new filters, spark plugs, even a new fuel pump and tools in hand I go to try and track down the problem. I have a home made lift and put the old girl up all keen and was...

Sorry haven't gotten to pulling it down yet, it has been horrendously hot here in Oz and not conducive to being in a shed with no AC :cool: Will report on findings once the weather changes for the cooler.

Hi all. I have a D125 with the 20HP V Twin and it intermittently will only run on one cylinder but then suddenly the other one kicks back in. It might run fine then for a couple of hours or it might play up again within minutes. I'm thinking probably a coil pack, I replaced the plugs even though...
