The screw which holds the clutch actuator arm in place, not sure what it's called but it's a specialty screw with a built in copper washer, and a notch cut out of the end, has a slightly different shaped notch for each bike. But either bracket will fit on either engine.
Each engine has different shaped brackets to achieve this, so you will need SRV brackets to fit SRV head covers. The cylinder head covers on the Virago mount from the top, whereas on the SRV, they mount from the side. (Of course apart from the ID Number, I went from 4DN-000136 to 3LV-021734 ) The Virago engine had a plastic chain/sprocket cover, so I was happy to be able to use my steel SRV one. All the engine covers can be swapped so the Virago engine looks just like the SRV engine. MY SRV chain length was fine and it fits the sprocket no problem, I believe the amount of teeth on the sprocket is the same if stock. You could probably drill two holes in an SRV sprocket to make them work, or if you wanted to you could probably replace the shaft and mount an SRV shaft in its place, but once again that seems like a lot of effort, I can just buy Virago sprockets from now on. The sprockets were incompatible so I had to switch to the Virago sprocket. The Virago sprocket has two screws either side which go through a guide plate.
The 1995 SRV that I own mounted its drive sprocket with one big central nut, and a washer bent around it to hold it in place. The Cams have different shaped lobes affecting performance, but each head will take each cam with no problems, the recommended valve clearances are the same for both bikes: Intake Valve 0.08 ~ 0.12 - Exhaust valve 0.10 ~ 0.14 Virago heads could be turned into SRV heads if you took a hacksaw to the fins I think, but I aint that desperate. You could use the Virago heads with their own carb, or possibly with a different carb setup, but you must have the SRV heads to fit the SRV carbs. The virago carb ports are flush with the fins, the SRV ports are recessed into the head, to make more room for the twin joints. Virago heads will fit in the SRV, but they will not be correctly spaced apart for the Carburettor joints for the twin carbs. I hope this list helps if you are in the same predicament as me: It was two weeks of hard slog, especially because I'm learning about motors as I go, and I've never been in an engine before now.Ī lot of my SRV bolts and screws were stripped/rusted/frozen, and had to be drilled/coaxed/chiselled out, which didn't do my arms any favours.īut despite claims to the contrary there are some differences and incompatibilities people should be aware of. So when my 1995 SRV-250 engine seized, I SEIZED the opportunity, purchased a 1998 Virago 250 engine from a wreckers, and swapped it in. I'd heard a lot of talk about an SRV engine being identical to a Virago, and that they could be swapped interchangeably, but I couldn't find anyone who had actually done it.
