ignition advancer mod

[Bob Broussard]

I'm still doing the advancer mod. Now that it's winter you guys/gals should be able to send your rotors to me. Price is still $5.00.

Send your rotor and I'll mod it and send it right back.

[Turkina]

I'm asking the stupid question...
Some of us have bought bikes, not entirely sure what has been done to them.   For example, I'm pretty sure my bike has been jetted, but wasn't told when I bought it.  How can we tell a stock advancer from a V&H or otherwise modified one?

[70 Cam Guy]

Hey Bob, how is the turnover speed on getting them out?  I've been wanting to do your mod for a while but I've been commuting to school on the bike.  Now that the semester is nearly over I can send the rotor to you if I can have it back before Jan 25

If it doesn't take you long to modify it, I could probably take a weekend drive down to Salinas so we don't have to mail anything

How can we tell a stock advancer from a V&H or otherwise modified one?

Pretty sure the V&H ones are stamped VH or V&H on the side facing out when you remove the cover.

[Bob Broussard]

The V&H rotors are black metal and have V&H stamped on them. Although some are barely readable.
The stock rotors are kinda goldish in color (some silvery).
They have 01D0 (part #) stamped on them.
The CA. rotor with 5 degrees advance has 5-35 stamped on it.
The other models have 12 degrees advance with 12-28 on it.
After I modify a rotor, I paint it black.
Also if you remove the rotor you will see a small hole for the crank pin instead of a slot.

Turn around time is roughly a week. With the holidays and depending on your location it could be a couple days more

[Puunjob]

I understand that this mod makes your bike quicker off the line but how does it do that?

[Bob Broussard]

The advancer sets the initial timing at 17 degrees.
Most GSs have 12 degrees with the CA. models starting at only 5 degrees..
The igniter box (black box) advances the timing to a max of 40 degrees above around 3000 rpm on all GSs.
So the advancer mainly improves lowend response. I'm not sure how it effects anything beyond 3000 rpm, but it will definately wakeup your motor.
Especially bikes with the 5-35 rotor

so i live all the way in bama. on the other coast of you. how much would it cost me to ship it to you. grand total, shipping plus price. also, how long do you think this would be? maybe 2 or 3 weeks?

[Bob Broussard]

Shipping has been around $3.85
So for less than $10.00 you can have a modified rotor that will do the same as a $45.00 V&H rotor (if you could ever find one).

Figure 3 days from you to me, 1 day to modify and 3 days back (1 week)

[suzukimad]

Bob,
      any idea what the shipping will be from the uk?.
Also how long will it take ship and return..

Sure a few in the uk ,will kill for one :guns: ...

I got mine(v&h) for the states a year back,cost lots$$$$

I've never sent any to the UK. It can't be much.
The package would be less than 1 LB in weight.
My zip code in CA is 93907.
Find out how much shipping will be from Uk and put the same amount in the package to cover my shipping cost.
The Christmas holiday is the only thing that will slow shipping.
I would figure about a week each way normally.

Are motorcycles not required to pass emisions tests?

[pantablo]

At least here in CA (and probably US in general) there are no emissions testing.

[ashman]

So Bob, it sounds too good to be true. Whats the catch?

Their is no catch Ash for three easy payments of ....
Sorry sounded like a infomercial.  :mrgreen:

Sounds like I could use a ignition advance too.

What a difference a few degrees of timing can make

My bike feels so much better now and the acceleration is much smoother.  I have a California bike so I'm going from 5 degrees to 17 degrees initial.  I'm not sure how the change is going from 12 to 17 but I'm really happy with my results.  It even sounds a little different at idle

Thanks again Bob

what is the probability of this part breaking or failing after you tamper with the OEM part?  how much would a new OEM part cost, anyone know?

I highly doubt the altered rotor will fail.  Bob fills in the stock slot on the rotor by welding it and mills the new locating hole for the crank pin.  The rotor is cad plated steel and I am not worried about it failing or breaking.  

I installed mine today and it went on without any problems.  I did a short run on the road to warm it up and adjusted the idle down a hair.  Changing initial advance usually changes the idle a little bit.

[Bob Broussard]

There is NO possibilty of the modified rotor failing.
It is simply bolted on the end of the crank. All it does is rotate with the crank.
It's nothing more than a piece of steel. The signal generator pickups are magnets that send a signal to the black igniter box when ther rotor passes by. They can go bad (rarely) but not because of the rotor.
A new rotor from Suzuki is around $60.00.
The dealer I go to has a new one in stock. If someone REALLY needed it, I can get it for $40.00 with my discount.

[Bob Broussard]

Yes I still do the advancer mod
