4 stroke FX140 in SJ

[texh20racer]

I got bored with a FX 140 4 stroke engine and empty RN so I thought I would answer the question no one was asking. And yes it fits, without most accessories, gear reduction, or coupler but with the gas tank in place. Now someone else actually do the swap, it would be unique.

any idea what kind of horses does that motor pulls and the weight?

 

[texh20racer]

The HO version has 160 hp and turns 10500 RPM but has a reduction gear to bring it within range. As for weight as it sits is prob. 90-100lb.

get a kart tank and do some fabricating...make it happen.

if you can fit an rxp motor in an sxr you should be able to do this

the 140 is 140 hp
those # are doable with a 2smoke and tons less wieght

 

[texh20racer]

The fx 140 had 140 hp but the HO version is the same external size but with a a bigger bore and a few tweaks giving it 160hp. Now why they still called it a 140 HO instead of fx160 is a mystery.

Sorry, but I don't think that engine belongs in a stand up. Maybe Rotax tripple would be a better choice, but still... I would not do it.

That is a heavy some b*tch!! When I shipped my 750 in a similar stripped down condition, it weighed about 50 lbs.

No doubt it's a cool idea but far from practical.

Where are the mount locations for the four strokes? I am guessing they are different than the triples and 66e.

save your time and money and put something in there that makes more HP and fits. http://www.waterdawgkustomz.com/1200.php
