Virago 1000 in 1981 XV 750

PostAuthor: longrider » Wed Jun 20, 2018 8:03 am

My old 1981 XV 750 Engine needs an overhaul and I`ve got a nice 1985 Virago 1000 engine in my garage. The 1000 has 2 pickups and I would like to know if Icould run the engine on a TR1 1000 TCI, because Virago TCI and pressure sensor are rare on the market and available only at exclusive prices.

If the TR1 TCI has the pressure sensor, then I would say yes, without the extra circuit for the pressure sensor, then I would say no.... Check part numbers for compatibility.....

The TR1s are made 1981-1984 so theres no pressure sensor. But the engines are nearly the same, so maybe the ignition timing.

I think you may be OK. The pressure sensor advances the timing at higher RPMs, so maybe a slight reduction in performance you probably won’t notice.

Some members here have done away with it, without adverse affects, or so they say.

You can even run them on your 750 ignition box, if you want to.

Think I`ll go with the 750 TCI . I`ve been told that I`ll only have to relocate some pins of the connector from the engine to the TCI.
