Re: 4 degree ignition advancer - fazer390 - 15-09-14
After fitting the 4deg advancer to mine the other week and not initially being impressed; 'I stand corrected'... :rolleyes
I did the London to Brighton on Sunday, which was the only decent run I've done since fitting the advancer.
Not only is it smoother, responsive and just as pokey, I've managed to get 215miles out of the tank with 4ltrs to spare! :eek Usually it's around 180miles per tank +/-
For my bike in particular, and I've had her now for almost 10yrs now!, it's been having some issues this last 12 months; starting, running, missing, cutting out etc... I've addressed everything electrical and fuel related including removing the alarm; the alarm being the main culprit!
The 4 deg advancer has been the icing on the cake which has finally reinstated full confidance of my old girl...
I wish I knew to do this years ago... :eek Re: 4 degree ignition advancer - trpFZS1 - 15-09-14
Great news. Have to say, since last full I have done 190 spirited miles on mine over the weekend and my fuel light has only just started to come on. I agree, the fuel economy seems to have improved a bit and the performance is not jeopardised. Low speed fuelling is better too and bike feels really good. I have just loctited the bolt so it's here to stay.
Re: 4 degree ignition advancer - fireblake - 15-09-14
Why? Why does this seem to make the bike better? Surely if a bike does better MPG and runs better then the emissions will be better, I don't understand why Yamaha would retard it by 4degrees if the benefits are what everyone seems to be saying.

Re: 4 degree ignition advancer - nsr500v4 - 15-09-14
Doesnt it have to do with the fact the bike is built to run on different (poor to good) grades of fuel in a variety of countries?
Re: 4 degree ignition advancer - trpFZS1 - 15-09-14
Hi Mickey. The eBay advert advises the following. "These advancers are designed to increase performance and improve throttle response particularly in the low to mid range as well as the starting of the bike. Bikes are designed to run as well as possible using the worst fuel available in the world and so have slightly retarded ignition to help with this. As we have relatively good fuel we can afford to run the bike with these 4 degree advancers fitted and have the bike run a whole lot better". Seems to work. Cheers, Rich.

Re: 4 degree ignition advancer - fireblake - 15-09-14
So, why 4 degrees? Is there a maximum amount of degrees, say 8 or 10?

Re: 4 degree ignition advancer - Falcon 269 - 16-09-14
The maximum is 4 degrees.

I fitted mine last night, it took about 10 minutes in total.
On the ride in to work this morning, it 'felt' like I had more power and a smoother pick up, so I am happy so far. I will know if there is any difference in MPG in a week or so.
Re: 4 degree ignition advancer - stevierst - 17-09-14
After reading the comments on here, I'm thinking about fitting one to my carb'd R1 and see if it makes a difference. I know the engines are 'almost' the same, so I don't see why it shouldn't???
Re: 4 degree ignition advancer - trpFZS1 - 17-09-14
The eBay ad says it fits the carb'd R1 and offers the same results

Re: 4 degree ignition advancer - woodwizzard - 17-09-14
I thought they weren't recommended for the higher compression R1 engines. Might be wrong though, but thought I read it on Ivans' site.

Remember! This is an R1 motor. Ignition advancers are not recommended unless you have significantly raised the compression!

Re: 4 degree ignition advancer - stevierst - 18-09-14
Yeah, I read that on Ivans site too and thought similar. Ivan, any thoughts on this?
Re: 4 degree ignition advancer - PaulSmith - 25-09-14
First full tank with the advancer fitted doing my normal commute and 197 miles took 18.0 liters, (49.75mpg) which is a few percent better then I normally get ~180 miles for 17Litres (48.1 MPG). Not a big enough difference to catagorically say the mpg is improved, but worth keeping an eye on.
Re: 4 degree ignition advancer - stevierst - 25-09-14
That kind of improvement will soon pay for the £15 advancer though!
Happy days!
Re: 4 degree ignition advancer - bigbluebear - 26-11-14
Just bought one and will get it fitted over the next day or so. I will also get it dyno'd and let you know the results
Re: 4 degree ignition advancer - mickvp - 26-11-14
I'm not sure what sort of difference it will make on the dyno, but interested to see the results.
Definately makes things a bit sharper in "real life" terms, but whether that is quantifiable in terms of bhp or torque, I dunno?
Keep us informed BBB

Mick did you install yours before getting invanised.
I decided go give it a go as I can always take it off if it doesn't suit me
