4 degree ignition advancer - nickodemon - 04-08-14
Has anyone fitted a 4 degree ignition advancer fitted to a stock fazer? What are the improvements (if any). I have one fitted to my full monty fazer and it improves it in the midrange, but want to know if it's worthwhile fitting it to a stock one.
Re: 4 degree ignition advancer - bigbluebear - 05-08-14
I'd be interested in fitting one to mine after the Full Monty upgrade from my Slip On being done in September......I'd be very interested in what this actually does to the performance and if its worth it and noticeable....I've looked at Pats Page but didn't see anything.
Re: 4 degree ignition advancer - Peasy - 05-08-14
Id like to understand the effect on stock too
Re: 4 degree ignition advancer - bigbluebear - 05-08-14
Looking at Ivans site....you can get 147bhp with an advancer, ported boots and K&N.....

Re: 4 degree ignition advancer - brooker81 - 05-08-14
i fitted advancer to my gen 1 thou but was done at same time as Ivanisied full monty so couldnt tell the difference as i didnt know whta made the difference. :rollin They ae only like 15 quid so worth a go either way surely.
Re: 4 degree ignition advancer - b1k3rdude - 05-08-14
And what effect would an IA have on a normal ivanised bike (just the carbs have been done).

You need to look at those a bit more closely, bbb.
First graph shows a top end power loss with a 4 deg advancer. Ivan doesn't recommend them for this motor.
The graphs showing 147bhp were for a motor with Muzzy full header system, not the Full Monty. The best Full Monty results I've seen were 140bhp. Your results may vary.
You feel the difference with an ignition advancer as sharper throttle response from idle to around 4k rpm. It picks up a bit quicker, that's all. No actual demonstrable gains on a dyno.
Since most of us don't routinely sit with the revs above 9k rpm, so any loss/extra vibes that high up the rev range aren't a factor.

Re: 4 degree ignition advancer - PieEater - 05-08-14
I have one fitted to my full montied Gen1 the altered timing gives better low down response at the expense of a few BHP off the top. It's made cold starts a doddle and low rev cruising even easier, you'd most likely notice the benefits of fitting one rather than the slight loss of top end. I don't really see what Ivanising has to do with it as the effect will be the same regardless but others will no doubt have an opinion.

Not quite sure if your saying its not worth it though....any advance in acceleration sounds good to me....is it something you would recommend and could add to the full monty install
Re: 4 degree ignition advancer - Falcon 269 - 05-08-14
I've modified the OE advancer on my own bike to give 2 degs advance because I think it's worth it.
A similar benefit can be obtained by setting the TPS dynamically as Ivan recommends - see the addendum in this post:

Re: 4 degree ignition advancer - nick crisp - 05-08-14
Hey Mike,
I know you've mentioned it to me before, but I was wondering if an advancer might be of use to me, having read your note above about it smoothing the throttle response between idle and 4k rpm.
As you know, when I first got mine, it had a very snatchy response in just that rev range at very small throttle opening increments, but the Ivanising largely seemed to cure that. Gotta say though, it is still there - not nearly so bad as it was, and I can quite happily live with it, but wondered if the advancer might improve things still further?
What do you think? Worth a shot?

Try the DIY option - definitely worth it in my view, Nick.

Ok, I'll take another look at that, cheers :thumbup
Re: 4 degree ignition advancer - nickodemon - 05-08-14
Fitting a 4 degree ignition advancer to a full monty fazer gives improved low down response and possibly a couple more horse power in the midrange. it also makes starting the bike easier. It doesn't give more top end power (possibly loses a couple at the very top of the rev range (i didn't notice). It makes the bike more driveable in my opinion and better in the range of revs that i use 99% of the time. I think i will buy a £14 one off ebay for my standard fazer and see if there is any noticeable difference.
Re: 4 degree ignition advancer - kitcrazy - 06-08-14
ive notice my gen1 is abit snatchy through traffic.is the ignition advancer something anyone can have ago at fitting?

An Ivans Jet Kit will sort that out
Re: 4 degree ignition advancer - ogri48 - 06-08-14
I only ever tried an advancer once, on a 1200 bandit..it kinda killed it..
