HOW TO: Vac Port MOD on Versys 650

[@TheSwissMotard]

Always a good idea to smooth out lumpy bottoms.

[@AndyManCam]

100% Agreed!

[@naitramde9256]

Just bought my 2011 V a month ago. This video was one of the first I saw when researching the V. Very good info. And then I was hooked on your channel. Probably half way through your chronology now. I've now completed the vac mod but won't get to test it for a week or so. The catalyst for tearing into the V, after much testing, is a fuel pump failure. Hopefully end of this week it will arrive.

[@AndyManCam]

+Nait ramde Thanks, it's good to know i might have helped a little! Fuel pump failure is annoying. But yeah, good excuse to get some work done while you're under there! Hope its all purring nicely now.

[@EinkOLED]

I have a 2008 blue versys in fantastic condition. I'm happy to live with it's imperfections if it means avoiding taking it apart.

[@AndyManCam]

+EinkOLED Haha! Then i envy you! I have am insatiable need to take everything i own apart. And then usually break it!

[@SpaceOut26]

I just got this model versys. these video's helped me a lot, the versys runs better now!

[@AndyManCam]

Very happy to help mate! Happy Versyssing!

[@billynightmare]

I have no idea what i just watched but i loved it, you are very entertaining!

[@AndyManCam]

Haha! Thanks Billy! Welcome aboard mate!

[@bloodyhell451]

Superb job. I don't know about 4 stokes - but I do know about two strokes. And you're right. You need to completly revise the carb set up if you change the intake. And it takes a day. With one carb........

[@AndyManCam]

I think it could even be more tricky than imagined as the ECU tries to alter the fuelling map to 'compensate' for more air than it's expecting. I'm still new to electrical tomfoolery and would be happier messing with a carb as it happens! It's so funny though how many folks think more air means more power and forget that the power comes in a curve rather than on or off! Though i also tip my hat to you old boy. Never messed with 2 strokes and they seem a bit of a dark art with their integrated valving, expansion chambers and whatnot!

[@bloodyhell451]

But it stands to reason that more air requires more fuel. Electrical tomfoolery aside...... I'm not going there !

[@AndyManCam]

vitaly deuterium Exactly! Can't get anywhere without upping both! Plus the fueling on the Versys is known for already being lean at the low end. I'm not going there either!

[@davidcarpenter8741]

I was having the off line stutter as well, new plugs and resetting the subthrottle plates to factory settings took care of it. This cav-port modification is a band aid, these bikes come from the factory way too lean and should be corrected rather then modified. The fuel mileage dropped considerably after resetting the subthrottle plates which makes me think the bike was too lean.

[@AndyManCam]

I agree. It's annoying that we have to 'fix' our bikes from new to make them work properly. But I guess the manufacturers have their hands tied with the need to squeeze the horses in but keep the low end emmissions down. Rubbish that your fuel economy got worse to fix yours though. You might want to keep an eye out for the upcoming boosterplug video....

[@theglove78]

Wish I had thought ahead with a fuel absorbing material when changing filter on Fazer. Was drenched (slight exaggeration) with the stuff when I took my tank off. I had of course remembered to turn the fuel off but brilliantly forgot to turn it on for my morning commute to work. Got as far as end of my drive. Much swearing followed.

[@briannotbrain1355]

Nice videos. Maybe consider stuffing lint-free cloths down into the lower air box ports while removing and replacing screws and bolts to help avoid the risk of them falling down into the engine?

[@AndyManCam]

Thanks Brian. That's a top tip mate. Well worth doing!

[@briannotbrain1355]

@@AndyManCam np. I really enjoy your videos as I just picked up a 2011 V. How is this vac port mod don't for you after a few years? Some like it, others don't.

[@AndyManCam]

TBH I didn't really notice it after I put it in. I guess that could be because it just did it's thing. hard to say! The effect of the boosterplug was far more noticeable.

[@briannotbrain1355]

@@AndyManCam gotta look that one up now

[@AndyManCam]

There are 2 vids on my channel! 😉

[@halosavage]

Great video! very descriptive and easy to follow. Have you ever noticed how the bike always drips a little coolant when you park it? theres a mod i did that stop it!

[@AndyManCam]

+halosavage Cheers! I'm very happy to hear it. I hadn't actually noticed that. I'd best pay a little more attention. I'm pretty sure there is still water in there.....

[@junglejarred6366]

Hi! I noticed. How did you fix it?

[@Kealbtl]

Every little comment was as if I was speaking through you; but more English than I. XD Loved the video!

[@AndyManCam]

Cheers matey! Happy to be putting an English touch to your thinkings! Thanks for watching!

[@mariusm5187]

thoroughly helpful and entertaining video :) Thank you

[@AndyManCam]

Thank you very much Marius.

[@Keldren.]

So, did it help at all? Was it worth the effort? I have a 2017 650 and am very interested in this mod..

[@AndyManCam]

I’m afraid i honestly couldn’t tell you. I broke the golden rule of science and changed too many things all at the same time. It was definitely improved but I couldn’t put my finger on whether it was one of the changes or a combination of all. The biggest noticeable change came from the Boosterplug though.

[@Derick9772]

I have a 2014 with power commander did you do this mod

[@jem5108]

Thanks! Great videos. Recently, purchased my first bike. I want to learn to do the maintenance myself. It needs a tune-up. I was wondering if I do a booster plug, will I need to do a Vac Mod?

[@AndyManCam]

+Jeff M Shouldn't need to. Boosterplug is a standalone.

[@jem5108]

Andy Man Cam ok, thank you!

[@ZohabZeeKhan]

I am still a bit confused about the vac-port mod. What is the actual benefit of the mod?

[@AndyManCam]

It allegedly does something to smooth the lumpy low end. Not sure how.

[@ZohabZeeKhan]

@@AndyManCam Amazing. Well I'll give it a shot and see what happens. Love your videos btw. They've been really helpful.

[@AndyManCam]

It’s the best you can do. If you don’t notice any difference, then simply return it to normal. If it does make a difference, even if it’s in your head, then enjoy the improved riding! Thanks for watching mate, I’m very happy to be of help!

[@Runawaygeekchannel]

I really like these vids, but please mention the size of things, like the hose, what size is that, how did you know it would fit on to the valve? Cheers

[@AndyManCam]

+Runawaygeek Thanks! Yeah sorry about that. I just happened to have the hose already so I'm afraid i have no idea what size it is! I just tried it and it was a win!

[@Runawaygeekchannel]

Fair enough, good videos anyway, i like how clear they are :-)

[@Runawaygeekchannel]

So its been a while now, has the Vac adjustment helped with the smoothing out of the throttle at the lower end?

[@borysdewar9741]

Hi. Outside diameter of the nipples is 4mm

Hola andyman tengo la versys 2007 Orange para q sirve eso? Saludos from spain🙋

[@AndyManCam]

Buenas Dias! It's supposed to smooth out the fuelling somehow. I'm still not sure how much difference it really made though.

[@tgap8817]

@@AndyManCam thank you

[@AndyManCam]

De nada!

[@laszlobudavari1365]

Hi Andy! She is 650/2008 and fitted with Booster Plug. Do you offer Vac port mod too?

[@AndyManCam]

I think it would be exactly the same. When I fitted the boosterplug later, I didn't change anything with the vac port mod.

[@laszlobudavari1365]

Thank you.

[@AndyManCam]

No problem! Hope you sort it out.

[@daverave999]

Have you considered replacing the ECU with a North American one? Did wonders for my 2007 UK version...

[@AndyManCam]

Wouldn't it be an incredible faff as I would also have to change the locks and the immobiliser? :(

[@daverave999]

Andy Man Cam didn't have to on mine? Which year is yours? I just swapped the other one in.

[@AndyManCam]

Mine is a 2006. Might be worth a look. Though I can't imagine an ECU will be any cheaper than getting mine flashed.

[@daverave999]

Andy Man Cam cost about £100 for a second-hand replacement. Never seen anywhere that flashes them though?

[@Langersport]

Great vid and thanks for sharing clear instruction on how to do this; I'm tempted to give this a go, even though I'm a ham fisted buffoon.

[@AndyManCam]

Langersport HAAH! You saw the bit where I snapped off one of my panels right?! I just use really short spanners so I don't have enough leverage to break stuff! But seriously, I think the only point you need to be really careful about is that fuel nozzle on the pump. Everything else is easily doable, even by the Ham-fisted! I did it after all!

[@AndyManCam]

Langersport So kind of you! But it's ok, I have broken stuff and I'm sure it'll happen again. Just hope I never break a penis though...

[@antuansteyn1444]

Where did you get the allen key ratchet tool? Think the Booster Plug would have fixed these issues?

[@AndyManCam]

+Antuan Steyn It's made by Rolson, and i got it from Maplin about 5 years ago. Sadly haven't seen one since. Shame, because this one has less teeth than an octegenarian bare knuckle boxer!

[@texasblaze1016]

Andy Man Cam i like the ratchets that have no teeth

[@jem5108]

Great videos. Thank you. I never worked on a bike before. Just bought my first bike. A Verseys 2009. 12000 miles on it. I'm doing a complete tune up myself. Getting help with a new chain and sprocket replacement. Working on getting the right tools. Can you tell me, what size tubing you used for the mod? Thanks!

[@edmundjohnyapebora3815]

2015 to 2017 they have same carb?

[@AndyManCam]

I’m afraid i don’t know. I would think so.

[@4842arendal]

So, did it make any difference?

[@AndyManCam]

Sadly hard to say as i changed a few things at once.

[@ivey77426]

you think this mod actually helps somewhat? or not so much?

[@AndyManCam]

+ivan petrov I think it definitely helped a little bit. Seemed to smooth things a bit. Though there is no telling if the ECU just counteracted the difference and changes fueling to compensate after a while. The biggest change so far has been fitting a BoosterPlug. I'll be making the video real soon!

[@ivey77426]

i had it installed by previous owner, but during initial after-buy checkup my mechanic removed it saying it is really bad idea to mess with a bike like that. Funny thing i am not sure i felt the difference :( Thats bothering me since i read a lot of positive feedback on the internet about it.

[@AndyManCam]

I think it is very difficult to say. Like many of these things, it's easy to convince yourself in your head that it has made a difference, when really it's a placebo effect. I did think as I read about the mod that there must be a reason that the bike doesn't come from the factory with this setup. After all, the Kawasaki engineers probably know what they're doing?! :D

[@salva33033]

.nice to learn I have same model

[@AndyManCam]

manuel galo Thanks for watching Manuel. Hope your mod fixes things up!

[@Bud_51]

Well? Did it?

[@krachenford9594]

the screws on the tank made me nervous

Steady hands! 😜

[@krachenford9594]

@@AndyManCam like a surgeon . . .

[@craigwatkin4721]

So Andy did it work???

[@AndyManCam]

Hard to say for sure. The bike certainly seems better, but figuring out the proportion of improvement from the new air filter, new spark plugs & the vac port mod is an impossible task! Still, better is always better eh?!

[@craigwatkin4721]

Very true. I've had my 2012 for 2 years now and have to say I love it. Just wish it had a few more horses

[@AndyManCam]

A few more horses would always be good! But I think my only real want is for better fueling and less lumps down at the bottom end. Seems that at 3000rpm it has 100% torque but at 2995rpm it loses 95% of it!

[@MathieuTechMoto]

Hi Andy, on my 2018 650 LT, i was chasing after the snatchy on/off throttle transition To solve the problem i did adjust the TPS (throttle position sensor) a little over the recommended value 1.13v@idle instead of 1.05v This results in richer overall fuel mixture , more smoother torque at low rpm and got rid of the snatchy throttle Better than booster plug And it's free and adjustable !

[@AndyManCam]

I read about that also having the knock on effect of messing with the rest of the fuel map position and causing other issues down the line. I guess you had no such problems!?

[@SportbikerNZ]

9:36 I guess we shall never know.

[@ianthomas3653]

Nice video. Are you on kawasakiversys.com? The forum could use these type of useful videos. Either way I enjoy watching your videos. Keep riding.

[@AndyManCam]

Thanks Ian. I have visited kawasakiversys.com almost as much as the UK counterpart. I just totally forgot that I hadn't yet posted these videos there! Thanks for the reminder, I'll get right on it!

[@pieplicht]

Nicely done mate! It really shows how to do things and recycling the footage used in the previous videos saves space on your computer( and of course you only took it apart once..right?). I also need to do any repairs on my motorcycle myself as I am a mere college student. Interested to watch me? Visit user/MrRidingOrange and let me know what you think! Really keen on some feedback as I am pretty fresh to motovlogging

[@AndyManCam]

Thanks! Yeah, just the one dismantling but an exercise in efficient recycling of footage!! One day we'll both be able to afford to pay those more capable to fix our bikes for us! But until then....

[@pieplicht]

On the other hand, We learn a great deal of how our motorcycles are bolted together. In the future we might be able to pay someone else but I believe that some things are too easy or too enjoyable to do. Wouldn't let someone else have your fun, eh? ;)

[@AndyManCam]

Pieplicht I couldn't agree more. I enjoy the work! Would be nice to pick and choose the jobs I like and the ones I'd rather not do though!! But I also have RAGING trust issues!! I'd pay someone else, and then take it apart to make sure they'd done it properly!!
