Procom CDI Review

Posted Yesterday, 05:34 AM

Okay. So after years of watching and reading posts about BBR, Big Gun. Yoshimura. etc. I decided to get a Procom CDI and test it for myself. I just got it Friday and installed it Saturday afternoon.

Unfortunately the recent wat weather might prevent me from testing it today.

The unit is typical. Decent package but smaller than the stock item so it is not a direct-fit replacement. According to Procom’s website it increases the rev limiter from 9,800 RPM to 10,000 RPM, which I like. I do not need, nor am I looking for, another 1,000+ RPM (or no limiter) on a stock engine.

I am solely interested in the increase in initial advance of two to four degrees.

A little background.

Back in the mid 70s and early 80s when Chevy V8s (and others) dropped to a miserable 8.5:1 we found a lot of gains by increasing the initial advance from 8 degrees BTDC to 16 or 18 degrees BTDC. Most HEI distributors were capable of 20 degrees of mechanical advance so this gave us 36 to 38 degrees of total advance. It worked great with low compression engines with stock iron heads (i.e. slow burn).

We also brought full advance in earlier and all carbs were re-jetted to accommodate the new timing curves. The increase in off-idle and bottom end was very noticeable. The top end also benefited from the extra 8 to 10 digress of total advance as did fuel economy.

People were amazed at how much more power was available from such docile engines.

I have been thinking the stock CRF230 with its 9:1 (or less) CR would also benefit from more initial timing and/or a faster curve. I have no concern about the total advance as I’m sure this is already close to where it needs to be. As I stated earlier I am not a power junkie who lives on my rev limiter.

I am looking to increase the off-idle and low-mid power of my bike. The Dial-A-Jet gave it a surprising wake-up in the low-mid already so I’m not too sure what to expect from this new experiment.

Below are some pictures of the Procom CDI in the stock CDI holder. As you can clearly see the Procom package is quite a bit smaller. The air line and small filter element is the air supply for the Dial-A-Jet system. The last picture is from dyno work Ness le French did on a modified engine. I have read horror stories about bad Procom units – No start, no run, or failure later.

I bought two just in case.

My CRF230 is bone stock except for what is shown in my signature.

More to come.

Okay. Here we go.

The bike started right up. No better. No worse. I rode around a bit to get it up to operating temperature and off I went.

The track is still a little wet so I didn’t expect much given mediocre traction conditions. I would call the off-idle and low-end response now twitchy. The throttle is now extremely sensitive to input. The smallest change results in immediate engine speed change.

Again – I am talking about off-idle and low-end. The midrange feels the same or maybe slightly better. No room to try the top and I really don’t care anyhow.

The one thing I noticed immediately was the change in exhaust sound. I don’t know how to describe it except the aaa in braaap is now a hard aaa instead of a soft aaa. Make sense?

The sound from a low CR car engine also changes when you add timing, as does the throttle response.

The Dial-A-Jet installation allows me to now lift the front end at will with a simple twist of the throttle. The new CDI added a bit more. With the Procom CDI I found the bike lifting the front tire out of turns while I was still on the seat. It would lift the front tire while standing on the pegs before but never while I was on the seat. Before you all cry BS remember I only weight 150 pounds.

The bike has tons of off-idle and low-end pull. It takes a handful of throttle in third with no problem. Once it gets into the low-mid it rips the tire loose or pulls the front tire. Power slides are a joke with the Dial-A-Jet and Procom CDI.

They are far easier to start and far easier to stay into longer.

I decided to run a section where I was testing last week. I came out of a turn and the bike pulled the front tire as it did after the Dial-A-Jet installation. I decided to stay into it, figuring it would give out and drop the tire before the next turn. Well. My hand position was not very good so I was not able to roll back.

The extra hit from the CDI kept the front tire off the ground just a little bit longer than it did before. I missed the turn and hit a small pine and hit the ground. I rarely fall so I figured BS and went around to try it again – This time with proper hand position.

Sure enough I had to back off to make the turn.

The bottom line is I got what I expected. More off-idle grunt and more low-end grunt. As far as high-mid and top I have no place to test right now.

I suspect there will zero change to those operating areas and I could care less.

I’m sure many of you are thinking BS. . I think the best thing I can do is set up a camera or strap on the Go-Pro and show how the bone-stock 230 carries the front tire. It makes me laugh while I’m riding. For the record I am a cheap SOB. I don’t believe in gimmicks.

I happen to know a lot about timing and carburation and I see no reason why I would not get the results I did.

I believe with the Dial-A-Jet and Procom CDI the bike is a changed machine. For an investment of $150 (Dial-A-Jet and Procom) you can’t go wrong IF you are an off-idle and low-mid torque junkie like I am. When I say my bike is bone-stock I should clarify a few things. I am using a 12-tooth c/s and turning a very big aggressive IRC Volcanduro VE-33, not some tiny, POS, stock, worn-out, tractionless Pirelli tire.

I run the same tires Al Baker recommended and equipped every one of his showroom bikes with. So when I say the bike power slides easier and longer it’s not because the rear tire is a bald, worn out POS. It’s because the engine is making a LOT more torque.

I wish I could have tested the bike with the Procom CDI only and no Dial-A-Jet. I bought a Procom CDI for my business partner’s CRF230 so we’ll see what he thinks.
