Any info on how easy they are to install, they seem to just plug in? Or is there a better way to get more horses in my BF 750. Installed K&N and 26" tires. What changes will I notice after installing the Dyna?

 

I'm asking the same question, I belive they just plug in, I'm just wondering about the jetting. I really don't like messing with carbs. [img]i/expressions/face-icon-small-sad.gif[/img]

 

The dynas are plug and play. You will notice a hugh difference. The brute will be a wheelie machine. I dont mean gas it and help it up. I mean gas it and hold on. Because if you can get traction the front end is comming up fast and if you dont let off it'll come all the way over. I don't think you'll have to rejet but if you notice the bike running hotter than before it wouldn't be a bad idea to rejet. The dyna advances the timing through out the entire rpm range. It also increases spark energy, does away with the belt limp mode, reverse limiter, and mine increased the rev limiter by 700rpm. I have seen alot of posts on the vdi copperhead cdi. I don't know how good they are cuz I don't know anyone who has one. I bought my dyna 2 years ago and haven't regretted it once. With everyone making a big deal about the vdi I put on a post wanting to know if anyone had dyno #'s comparing the two vdi vs dyna. No one replied. So until I see one first hand or get hard data saying the vdi is that much better than the dyna I'll stay with my dyna. All in all with the dyna you'll have the same old brute just with more muscles.

 

I just installed a Dyna CDI. I havn't had a chance to ride it yet, but did do a lot of research prior to getting one. From all of the information I have gatthered including talking directly to VDI, they both do the exact same thing. Other than the fact that the VDI does allow some user changeability if the need arises. Honestly I can't figure out a reason why one would have to change their timing unless they are running nitrous etc. I know that the Dyna had some issues in the past, but they have seemed to regain reliability in the last year or so. There have been some hickups with the VDI housing screws not being sealed at the manufacturer, that is a little disconcerting. The Dyna is potted, meaning there is no way for moisture to enter the unit. I thought KOD was going to get them both dynoed, but I havn't heard back anything yet. For the money I can't see paying another $100 dollars just so I can plug my laptop into my atv. I would hope that the designers would have done the timing work prior to manufacturing the product. If they did it right I don't see many advantages to changing your timing curve past what the CDI already does.

 

Torridone, are you talking about Dyna CDI or OEM CDI here?CDI

 

Sorry, my point was concerning the VDI CDI. If they have done their homework and got the timing right, then there is no need to have the adjustablility their unit offers via a USB connection. Unless nitrous or extreme modification is involved. I think the market for this type of adjustability is very small, yet still a lot of people buy into the whole "I can change my timing on my laptop". What does this really give you? If anything you risk hurting performance.

 

I just got the Copperhead from VDI and it plugged right in. It was well sealed and I coated the terminal plugs with terminal grease, I don't forsee any problems with it. It made a noticeable difference, even with the tracks on. The only thing I can compare it to, is the difference I got when I changed clutch springs on the V. It's almost tempting to take the tracks off, just to see what it does with the tires on.


It came with preprogrammed settings, I can switch from stock to performance with a sealed toggle switch. If I was capable of using the interface [img]i/expressions/face-icon-small-wink.gif[/img] , I could set different performance curves, depending on humidity or temperature changes, probably useful for drag racing, but possibly even elevation changes? I'm not sure. I bought it because I've read many good things, and for me they are a Canadian company. I ordered it on a Friday and received it on the Monday, can't ask for better service than that.

 

Do you know what setting to change for altitue, air temp, humidity etc? If you don't know where to change to, then your just stabbing in the dark. But hey, you can plug a laptop into it.

 

I'm not arguing with you, there is zero chance I will ever plug a laptop into it. I was just offering possible benefits. I'm sure that there are guys that would know how to do it. I have a good friend that drag races sleds and he changes his jets on the line, not to mention his clutch setups. There are alot of hardcores out there.

On the other hand, say I get an 800 kit, new exhaust, jet it appropriately, I can probably send back my CDI and get it reprogrammed, FWIW.

Thanks alot guys for the info. I hope to get one very soon! [img]i/expressions/face-icon-small-smile.gif[/img].
