Hallo Leute!

Habe eine Frage... Zahlt es sich aus einen Xv1000 Bj84 Motor in die Xv750 bj.83 zu Pflanzen?

Ist es bei dem 1000er Motor auch möglich mit den 750er Köpfen zu arbeiten?

Lg Gerald

Hallo Gerald,
ich fahre seit 1993 einen 920er Motor in meiner 750er (5G5) und bin nach wie vor sehr zufrieden, das lohnt sich auf jeden Fall.
Der 1000er Motor hat gegenüber dem 920er den Vorteil des besseren Anlassers.
Ob die 750er Köpfe auf dem 1000er Motor funktionieren, weiß ich nicht.
Gruß Babsch

750er Köpfe funktionieren auch auf dem 1000er Motor. Im Prinzip hast du dann einen TR1-Motor nur mit Kardan. Inkl. aller Umbaumöglichkeiten (Kurbelwelle, Zylinder von der 1100er usw.), so wie bei einer TR1.

Hello Gerald

You have to consider the following:

1. Most XV750 engines are shaft drive, the XV100 is chain drive. So you will have to replace the rear wheel. The rear swing arm on the XV750 accommodates the shaft drive so you may have to replace that as well. Also the XV1000 has a different exhaust system so you will need to change that as well.
2. The starter mechanism on the XV1000/TR1 is better, use a four pole motor. The starter solonoid is placed in a different location and the wiring harness is different.
3. As Nanno says you can mount 750 heads on the XV1000/TR1 it is a well known performance enhancer it increases compression ratio. If you are based in Germany your XV750 cams may be 'low power output', you can replace them with XV1000/TR1 cams for a performance increase. UK XV750 cams are the same as the XV1000/TR1. Just check part numbers.

Best of luck with your project.

You forgot the XV1000 Virago, which was a shaft drive model! So there is no need to replace the rear swing arm and the wear wheel.

Hi Kevin,

as Gerald is local to me (Austria) and we had a little chat and it is in fact a shaft-drive XV1000. Unfortunately a very early one, so it suffers from the same basic headgasket issues as a TR1. (Which is at least partially what he wanted to overcome.)

Cheers,
Greg

Hello Greg

Then it may be worth just changing the barrels for those of an XV1100.

The barrels are the same but the top of the barrel is flat, no cutouts. Just use an XV1100 head gasket.

Please see attached photo.
