FXR ignition curve?

[richban]

Hey

Been looking into an igntech ignition for the FXR. They don't have the standard ignition curve data. Does have any info on the standard curve.

Cheers

Is your bucket not fast enough Rich?

Fast is never fast enough.

It's a 4-stroke 150cc. Start at 25 deg btdc and at about 5000rpm switch to 72 deg btdc.

Let me know how it goes.

damn right! :Police:

I'm hoping that you aren't really going to try that.

No. I was thinking of some elaborate come back but nothing yet. What ever the setting ends up being it will take some time to sort. I want to raise the limiter to around 13500 and see what some advance unleashes. At the mo there is power above the 12500 limit.

The conrod?

Please oh please oh please go bang!! Haha kidding

From watching the Chch guys online I'd say that the rod will end up doing your rev limiting for you.
Can you get your hands on a 600 IL4 curve with about the same bore and stroke and poke that in there or is that me being far too simple?

I have a Igntec ignition but I am yet to run it.

It came with the right plug for the wiring loom.

Anyone want to try it first?:eek:

I have confidence that this engine will last a little longer yet. It was built well and has lived a 12500 for most of its short life. 600 curve worth a look. It shouldn't be to hard with a knock sensor and some time.

Are you still using the standard CDI?

Yep. Not for long. I will post Dyno results if I tune it on a dyno.

I would be very interested in seeing a dyno chart for the torque curve of an FXR.........

I will try and find the old print outs.

[richban]

Found one. Ok engine spec at this time was pretty much standard. Short crap exhaust and Mikuni TM28. I think that the dip in the middle was reversion due to a badly designed exhaust. The difference between the red and blue is the carb.

I have one more of the worked engine but can't find it. The fueling is all over the place and was a bitch to tune. I later discovered it had a manifold leak. Big waist of money lesson learnt. Still made good power.

Thanks Rich for posting the graph, very interesting to see the shape of the hp curve in comparison to our strokers..........we think it's where the FXR's have it over us at Mt Welly, but we are working on it............

After the new exhaust was fitted it felt very linear. Dip was gone. Can't find the other one but if it turns up I will post it.

I tried my Igntec ignition on the bike I just purchased and it ran fine... so they come pre programed as standard.

It is just plug and play... dam good compnay.
they will not just seel you the ignition without asking heaps of question etc... when they are happy with what you are getting they send you an invoice.
