fancy tool

[BigDick]

So is this a decent setup? I'm naturally, inherently lazy, therefore I don't want to build my own fancy setup.

There are guys that use that set-up.The only thing I dont like is how do you know they are all calibrated the same?I suppose they have to be pretty close from the factory.You could check each one before the sync by hooking each one (one at a time) to the same cyl.
It will work anyway though.
I bought a crab tune pro last year,I lover that thing.I can pull it out of the case and hook it up and sync in a few minutes.

The only problem with that setup is finding 4 gauges that have springs that work EXACTLY the same. For just a little more, there's a setup that uses rods that get pulled up (Instead of mercury) I can't think of the name of it right off the bat, but I know Wildkat just bought one for John for Christmas and thinking it was right around 100 bucks.

It's a little more, but it will be much more accurate for a much longer time than the gauge setup.

As long as the gages themselves are good quality your good to go. I use 4 gages to sync my carbs because I find that as the engine runs better while you dial the carbs in ... the numbers can change across the board. With 4 gages you can really dial the carbs in nicely. I like to color tune. sync, color tune again and sync again. The bike runs very nicely ... like factory.

The problem with a 4-gauge setup is the gauges have to all read/be calibrated EXACTLY the same to accurately adjust the carbs. So any variation in the gauges will prevent you from getting the carbs all the same. You may be CLOSE, but not as close as the 'homemade' setups that use either a single gauge or the 'spirit level' types that tie together.

In this case, cheaper is better....

The name is the Morgan Carbtune Pro. The best I've ever used. Well worth the 100 bucks and WAY better than fluid sticks IMO.

Thanks muchly everyone. I'll check into that and get me one with this paycheck.

I use the setup pictured above. Some have said it is cheap and inacurate, but this is just not true. I took my vac pump which has a guage and calibrated all 4 guages the same. I've never had any problems with these. I use them on my bikes and friends bikes and all of them purrrr.

[Crazcnuk]

We also use that one. To check the guages, I just hook them up to the same cylinder, one at a time.

So far they have not needed calibration.

I built a set with Harbor Freight combination gauges - usually $12.99 ea., but sometimes you can catch them on sale for $8 - and needle valves from Ace Hardware for damping. I calibrated them the same way Craz mentioned, and put stickers on each on so I wouldn't forget. Here's a pic...

[79XS11F]

That's a good observation and dampening valves will be needed. The ones I have, have a damping valve at the bottom of each gage where the hoses meet the gages

Rob - I might have got you on the dampening valve. After my post I checked more closely on the JC Whitney site, and they say that gauge set has dampers, but darned if I could see 'em in the picture. Anyway, I went back in and edited and removed the first line.

You've got the gauge set I want! I've seen 'em on e-bay for $99 with a nice aluminum case and all the nifty attachments.

That's right I got mine from e-bay and they are packed in a nice case with enough attachments to fit many bikes. I love them and they were CHEAP. Going back to when I owned my first xs11 a set of gages like these would set you back a full weeks pay. The gages are also S&W which is a good quality manufacturer of this type of gage.

I checked ebay, and they still have 'em but with a plastic case. Still very nice. http://cgi.ebay.com/ebaymotors/Carbu...motiveQ5fTools

They also have them with the aluminum case, but the nicer case will cost you $20 more. http://cgi.ebay.com/ebaymotors/Vacuu...motiveQ5fTools

Thanks, Tim.

You are right. It's the Morgan Carbtune. John and Wildkat have a nice 4 gauge set, but since getting the Morgan, I doubt he'd ever go back to it. Not trying to knock his stuff, but Rob's setup looks like a nice one, and you can see that the first gauge is off a bit from the others. If it is in use at the time of the pic, that is a different story though.

If you're happy with your 4 gauge setup and it works for you.. great. But... if it were even close to the same money for the 4 gauge or the Morgan Carbtune... the Morgan would win every time for people that have ever had the opportunity to use one. If using a single gauge setup.. anyone who has ever had a 4 gauge setup and watched all 4 readings change when you adjust one carb.. knows that this can be a nightmare and an educated guess at best sometimes. Yes it can be done.. and yes I have done it myself, but there were many times that I got the carbs so messed up, that I had to pull them again to bench synch them to get close enough to start again.
