After having read through this thread I am still trying to decide whether to go with an 01 CR 250 ignition or the CR 500 ignition from Service Honda. The CR 500 system is apparently made by Electrosports so I'm wondering about their quality? It seems like I got a stator from them a few years back for a Tecate and it didn't last long. I know Honda OEM quality is good but I'm not sure about Electrosports. Is their stuff made on the cheap in China?

Unfortunately any of the aftermarket stators are going to be from china, the question will be are they from a good Chinese manufacturer, only time will answer that.
But I have not heard of any bad ones yet, but its still early in the game.

Any word on which setup--the OEM CR 250 or CR 500 with lights--works better with the TRX? Studying the timing curves is interesting but I'm wondering if there is a bottom line? The difference in the timing curves seems to be below 1000 rpm and above 9000 rpm, otherwise they are pretty similar. Service Honda sells the CR 500 system for $530, which is pretty good compared to OEM. I'd rather spend a little more on OEM, however, if it is the better setup.

bottom line is every motor combination has different timing needs, its not as simple as what year is the best for everyone. Your porting,engine size,pipe and dome all have a factor in what your timing needs are.
The whole reason you have advanced timing and take it away as the rpms increase is because the efficiency of the motor increases with rpms so less ignition advance is needed. Not every motor will need the same amount at a certain RPM it all depends on combustion efficiency.

I know this is a speculative question but do you think the added weight (200g) to the CR 500 ignition would offer the equivalent inertia of the stock TRX rotor? I'm looking for a quicker reving engine so I'm disappointed the weight appears to be stamped on. I suppose I could get an OEM rotor off ebay but then the pulse trigger is shorter and I don't know it that would create problems.

I believe it will still accelerate much faster than the TRX flywheel running with the small CR flywheel even with the added 200 grams because of its diameter
I did not weight a TRX flywheel but they are not light and should have more inertia
The flywheel for the CR can be lightened also if does not rev as much as you hoped for, but there are many times you will wish you still had some of that inertia of the big TRX flywheel. Remember the heavy flywheels absorbs energy but does give it back.

Here are the pictures of the CR 500 ign with lights. It mounts in the stock location with the OEM rubber holders and all wires are used other than the tach input. Engine is new to me so I cant compare how it starts but there is no kickback even when
it back fires out the exhaust. Engine sounds very crisp and will idle forever if you let it. As you can see I am still in a neck
brace due to a bad crash in April and have not ridden it yet but I will give a ride report as soon as possible.

I want to thank RSSS396 for all of his help, Jim

Also I mounted ignition coil on left side of quad or I would have had to lenghten coil wires.

Are you using the cr 250r ignition stator mounting plate (looks to be ESR) with the cr500 ignition ?

Tony

That is an old picture with a cr 250 adapter from BTD. They sent me a new adaptor for the cr 500 ign but I dont have a picture of it. to much pain meds and lack of concentration. The cr 500 adaptor is very similar.

rsss396 · « **Reply #87 on:** August 21, 2013, 07:35:18 PM »

Jim I thought I remember the adapter being the same as esr's
I know they are different between cr500 and cr250 but you just normally run a small ring to adapt the larger recess of the cr250 to the cr500. But I just might be wrong on that, do you still have both adapter plates?

Good to see you around you have not posted in awhile, glad you got the halo off!

You are correct I had to read this post from the beginning the adaptor plate is the same

Thank god that halo is off I dont think I could have handled it much longer !!!!!

So how's it going bud, any up dates on the bike.
