Hi,
maybe the parts may fit but the starter´s torque isn´t strong enough for both cylinders with 1000 ccm! The starter motor of TR1 has another mechanic as the XV 750 starter.

Hi Keith.....Bob here. I have an XV920RH that I will be upgrading to 980cc (1000). To do this I will need to have my crank case bored out to accept the larger cylinders. In addition to this you will need to obtain some 920 0r 980 con rods as the piston pin bore is 2mm larger for the 920 and 980 pistons. Your cylinder heads will likely have to be changed as the combustion chamber and valves will be too small. You would wind up with an engine that could not breath properly and would have too much compression to burn pump gas. Don't worry about the starter as there is an upgraded 4 brush model available which is much better than the stock unit.

Hi Keith.....Bob here. I will call the parts shop tomorrow and get a part# for the upgraded starter. I put one on my 920RH and it spins the engine over like I've never heard it before. I paid $385.00 CDN ehich is about $275.00 US. Its worth every penny. I also installed an absorbed acid battery (made by Deka). This battery is highly aclaimed by that unfortunate group who ride Harley Davidsons.

has anybody tried fitting a newer xv750 engine in place of an old se unit, have ahd an se for a lot of years sprayed in oil languishing in a garage with a very tired engine but a good rebuilt chassis, would love to get round to sorting it out some day
