Can I run a Dyna CDI and my 4 deg key together? I am wanting to get a CDI but am not willing to open the motor back up to swap keys.

 

the dyna and degree key may be too much timing, not really sure they will work together.

 

any truth to this?

 

i'll look into this a little further for ya!

 

you can program the VDI to take the 4* into account.

Thanks for the replys guys. I knew about the VDI but don't wanna spend that much. This bike will never get cams, high comp pistons, or a BBK so the VDI would be wasted.

 

hey, this is what i found on the highlifter forum!


"The Dyna CDI is already 34 degrees and going above 37 degrees can actually hurt performance and engine. I would not add a key at all from experience with my prairie. I removed my 4 degree key for better performance with the dynatek cdi.
If you get the copperhead you can retard the cdi to work with a 6 degree key. The dyno's I've seen above 36 degrees had no performance increase and it is dangerous."

also found that the key also does not work well with a module either, like the Highlifter, Moose, or DG5. the bike will hardly run because of too much timing!

 

Incorrect.
You can run a degree key and any module together with no problems.
Myself and many others do. A 4 degree key and a module will only give 32 degrees advance. The module has no effect on maximum timing advance, the factory CDI is limited to 28 deg, a module does nothing to change that.

 

i was just stating what someone elses expierience was. they had a BF650 sra with a degree key(ran great) and added a Highlifter module and the bike would barely run(said it would hardly go down the road). the module was put into another bike and it operated fine. so, they concluded that a module could not be run with a degee key. i dont know much about the timing, keys, and such. i was looking for info for someone else. seems that some can and some cant, kinda like the miss the DYNA CDI produces on some BF750's and not on other BF750's.

 

So would I see an increase in performance by taking out the key and put in the Dyna? I am at 32 degs now and would be going to 34 degs. Is it worth it?
