XVS 1100 starter for XV Gen1

PostAuthor: beltdrive » Tue Jan 24, 2017 5:16 pm

Hello Guys - - help me on this idea

A lot of XV Gen 1 750 - 920 get the starter modified with a solenoid unit from xv 1000/1100, this take a left side cover and new gears and solenoid and the works -and it does - work.

Now looking at the XVS engine, it looks a lot like a XV Gen 1 in the starter area, so I looked at the spare parts drawing, I started a very dangerous thing called thinking

I think the engine casing are the same as on the XV ? or at least in the starter area, that could mean that the distance between gears could be the same as on the Gen 1

I get the idea, that it is possible to convert the XVS starter system to the XV Gen 1, by swapping the gears inside - taken of the starter ring gear on the backside of the flywheel and replacing is with the XVS starter gear-system, this is a lot fewer parts and looks a lot smaller to, as the solenoid system is kind of a " BIG thing "on the front of the engine .

OK what do you Guys think of that, have anybody tried this

Thanks from Erik

Maybe. Maybe not. The XVS is much wider on the left in order to move the shaft drive output outboard so that a wider rear wheel can be used. And part numbers doesn't match up. Still, you never know, perhaps it will work.

I've been a member for close to 10 years and as far as my memory serves me, no one here has done it. I don't think the subject has even been discussed.

Thanks guys

This was - is one of my big problems as a ( former) industrial designer, you sometimes see things, that nobody think can be done and sometimes they are right and other time it actually can be done.

Now I will get some used parts to work with, I have a spare engine (TR1) that I can work with.

If Yamaha could build a different starter design in the same casing - they would, as making a different casing is very expensive.

My concern is how wide is this system, or is the XVS crank longer? - as I think the distance between the 3 axles is the same - starter motor - gear axle - and crank, if this is right it is only - how wide is this system, as it has to fit behind the flywheel

Now I will try to get some sleep

Thanks guys, and I look forward to more input

Thanks from Erik

Several members have bought XVS engines in order to use the top end and crank on/in their old Gen 1 engines. Meaning some here should be able to measure stuff for you. Hellgate is one such IIRC.

Looking at the parts fiche, I kind of have my doubts. The side covers are completely different as it the crankcase cover.

That's just my perspective, yours on the other hand may be different and seeing what you've done with the beltdrive, suggests if it's possible, you are the one to do it.

Thanks all - we are getting closer

THE STORY BEHIND THIS IDEA - - - I have been so lucky - - I just board a " NEW " 1982 Virago 920 J - - -10L - yes I drove from Denmark to Holland to pick it up - it has 31k miles on the clock, and is so well preserved, that the original seat is not cracked and there is no wear lines on the fork tubes ?? Yes the first Virago YEAR 1982 . Yes with Yamaha cycom - yes with all the extra - like double disk up from, air assist front and back, and damning adjust front and back, adjustable alu handle bar.

Yes Yamaha´s original idea of a V twin, long before the harley look alike design aura .

I am trying to find out more about this bike, the word is, it came from the states and was first registered in Holland in 1987 - it is black, I think it had hard saddlebags with built in turn signals at one point, as the original rear turn signals are missing - and some others are mounted instead, after the bags with built in turn signals was removed, ( this is a guess) the plastic cover around the ignition key is missing to, other than that everything is original - yes even the exhaust system is original - - and it is a lot of years ago I saw a 1982 Virago with a original exhaust system.

We all know how bad the starter is, so this is how I got the idea to use a XVS starter system as it "looks " a lot like the original Gen 1 engine in the starter area, and I avoid the bulky XV 1000/1100 solenoid system, that I could built on, but if this is possible - it would look a lot better

Any advise is appreciated

Thanks from Erik

I'll look through my photos of my XVS motor. I may have some of the case covers. My motor didn't come with any of the starter bits. I do remember the case covers having webbed castings to make the motor look bigger, and have a Harleyesk visual profile.

Here's a photo of my donor motor. Note the enclosed case cover around the starter motor.

Man, the P/N are completely different, but looking at them they are very similar. Note that the XVS uses a modern starter clutch. I suspect you could transplant the XVS (massive) case covers on the XV and use it. You'd be the pioneer.

XVS Star: 5EL-81890-00-00 MOTOR ASSY http://www.boats.net/parts/detail/yamah ... 00-00.html

XV920 Gen 1: 42X-81800-60-00 http://www.boats.net/parts/search/Yamah ... parts.html

Interestingly, Yamaha is now selling a NEW starter for Gen 1 bikes. Hooray! Once my aftermarket POS dies I'll try a real Yamaha one.

I hope this helps.

Oh, and the crank just drops in from the XVS to the XV case.

Thanks Hellgate -

That means that the cranks are the same length and the space behind/under the flywheel is the same, then there has to be enough room for the starter gear behind/under the flywheel, OK I will find some parts and work some more on this.

In the parts kits I find - there seams to be missing a bearing surface for the roller bearing to run on - that bearing surface is part of the flywheel - I have found, so maybe I need the flywheel centre piece as well to mate to the Gen 1 flywheel - or can the XVS flywheel fit in the Gen 1 engine?? - or can the Flywheel base fit the crankshaft?? - as I think the XVS flywheel is bigger

I look forward to any thoughts

Thanks from Erik

OK update

The flywheel/generator on XVS is moved ½ inch out, to make room for the one way clutch, that is mounted on the inside, so in order to use this starter on Gen 1 , I have to find a way to move the flywheel/generator ½ inch out, that will require a ½ inch move out of the side cover - how do I do that - I need a alu welder guy, that can weld a ring onto the side cover take make the room

Anybody know if the XVS generator is same diameter / width/ thickness as the XV Gen 1 ??

Will the XVS flywheel/generator fit on the XV Gen 1 crankshaft ?

Please anyone have the metric measurements of a XVS flywheel or know were to find it, that is cheaper than buying a flywheel, but maybe I have to anyway,.

This project is not dead, I just have to much work to do between my wrenching, if it is a success, I will make an instruction manual fore it.

OK guys - I need help - I have a Gen 1 flywheel, I can measure, now any body have the measurement for Gen2 1100 flywheel, anybody have measurement for Gen3 - XVS100 flywheel?, they are expensive, I would not buy them all just to measure them, and I am not sure I can find somebody that have them all laying around.

Anyway, if I do not get these measurements, I have to find somebody, who have them laying around.

Thanks from Erik
