Has anyone successfully changed sprockets on the F3 Limiteds?

[vitodivita]

My friends got the 2019 F3 LTD with Monster Stage 2 tune (yes he should have bought an S) and wants more low end pep. Has anybody successfully changed out the sprocket to no errors?

 

[Peter Aawen]

No.

 

[larryd]

No.

Peter, Show vitodivito how to get intouch with Jase down your way...I've been talking with Jase about the sprocket change challenge...Jase said he thinks he has done this and was going to check it out after his move to his new shop...

I'm pretty sure I remember someone wanting to change their F3 sprockets several years ago and BRP stepped in on their post and said to have their dealer contact them??? (I think)...I know several have tried since that post without success...But the F3's have both options 79T & 89T...So I think its doable with the correct knowledge...Now the RT's don't have that option, so I think they'll be a BIGGER challenge...larryd

You're right Larry; if anyone can convince the ECU to let a change of sprocket on a Spyder to work, it'll be Jase! hyea:

His contact details & a brief outline :

Jason Robertson at 'ECU Xtreme' - that's the label on their Facebook page or you can email him at [email protected] - Jase has been working on/with Can-Am ECU's for longer than most in the game, and he's generally the 'Go To' man for troubleshooting all the 'unsolvable' ECU & tuning problems for BRP, dealers, & private owners alike all over the World; and he also does a lot of tuning & fine tuning/getting the ultimate in performance for many manufacturer & privately owned competition machines on the World stage too!! These days, you too can access all that knowledge & skill - for a fee of course, and yes, it's not the cheapest ECU tuning there is available out there, but I am convinced that he's forgotten more about this game than most tuners will ever know, and I certainly think that what he does is up there at the top of 'the very best' heap! But then, I have already had his magic worked on my RT - I didn't change the sprocket tho, cos not too many machines have quite the same 'pep' as mine does now! hyea: :yes:

For those interested, I have no involvement or interest in this company, financial or otherwise; I am simply an extremely satisfied customer who has tried more than just a few of the other ECU tuning offerings who finally learnt about Jase & ECU Xtreme & now that I've experienced his work & support I won't recommend anyone else! :thumbup:

Thanks guys I sent a message out to him as well as Monster for curiosity sake. I will report back..

You didn't say, but does your F3 NOW HAVE the 79T rear sprocket and you want to change to the 89T for quicker acceleration ???

 

[vitodivita]

Correct it’s a 79. It just doesn’t engage at all like the S does. There’s boatloads of torque but it’s being held down by the gearing and traction control.

I have a 89t F3-S and wonder what the 79t would feel like...

I'd imagine it would be like starting your F3 S in second gear and running it into a hypothetical 7th gear, it's not exact but close to that.

 

[troop]

Other than the 79t/89t final drive ratios, I wonder if the transmission/gear ratios are the same between 79t and 89t models? Maybe like driving a lighter weight F3L?

 

[vitodivita]

Right that's a good point, could be the trans too, hopefully I can get some clarification on this.

 

[Rattlebars]

Easy to tell what you have. 79 has three spokes and 89 has six spokes. I have mine offset so it looks like I have 12 spokes on the rear wheel.

 

[troop]

We both know what respective pulleys we have. His friend has a 79t F3 Limited, and I have a 89t 2019 F3-S. My pulley is damn near same diameter as my rear wheel..

 

[Highwayman2013]

I guess we were lucky without knowing it but our 2016 F3L came with the lower gearing.

my wifes 2018 f3t has 89t my 2019 f3t has 79t

 

[Freddy]

my wife's 2018 f3t has 89t my 2019 f3t has 79t

That's a good example of BRP's engineering excellence and customer confounding. :shocked: One wonders why they would do that! :chat:

Easy way to increase performance...larryd

 

[troop]

I believe the initial use of the 89t on LTD models was to have the lower gearing for trailer towing purposes..

Then you would have though they would have made it an option on the RT's since many are ridden double and some tow trailers...Plus the RT's are heavier to start with...larryd

Transmission ratios are the same in all 1330 SE engines built 2014 to present.
