Is it better to run the red box with the 1250 instead of the black box? I have the rectangular one with the vacuum removed

[AKRACER]

39-40.

any advantages to higher or lower timming baised on fuel/track size and rear end slection?

[legends13]

All I can tell you is what I have been told, as I am no engine expert, but... 41 is about the highest you want to go. And at 41, you will have good power initially, but once the engine gets hot, you will lose HP quickly.

As for Red Box V Black Box, everyone has an opinion. I have always liked the Red Box, as it is simple, has a good rev limit, and allows the use of the blue plate for adjusting the timing.

The black box works well also, but you can't manually adjust the ignition timing like you can with the red box.

brad do you use a timming light? or just a static adjustment?

it is a static adjustment. The blue plate on the engine is marked, and the mark corresponds to the "line" that the 2 engine case halves make. It is hard to explain unless you are looking at it, but then it is a very easy adjustment.

I have red box with red coils, how do i check my timing or set it??

the marks on those plates mean nothing........it has to be done with the correct equipment and a degree wheel.  I've seen those marks more than 5 degrees off before.

How about some instructions on using a degree wheel to time this.

I can see the degree wheel being more accurate, but I highly doubt that Dynatech is putting out plates that are 5 degrees off. As these are made for street bikes as well, there would be numerous issues if the timing was that far off.

I have never had a problem setting these, as long as you take some time and do it right.

Installed a new engine and is running uneven.  Very choppy .  what reading should I have for blue plate and how do you adjust?  Also how can I assure all four cylinders are running.  Thank you

[Lenny]

Whats the definition of "advance" related to engine tuning?

Any takers? Or is this a subject that just gets mentioned like bait?

dyna sells a tool to set these plates, or they used to.  I've seen cyl 1&2 pickup as much as 7 degrees off from 2&4 pickup, right out of the box.
