Plus one on that!! Everytime I read that the 1330 needs "backpressure" for low end torque I question the origin of this... I pulled apart a stock cat and trust me, there is little to no...

Europe uses RON only measurements so the number will show higher for equivalent fuel in the US, which using PON - an average of RON and MON. eg 95 RON = ~91 PON.

As for the Maptuner, I love mine....

Some of the ecus need to be opened for enough access to crack the access code. Once cracked others of the same version dont need to be opened.

Re millerdjr and back pressure. ...Yes I totally agree. It's NOT back pressure causing the problem with a cat delete, it's pulse timing!! There is virtually NO back pressure with the stock system...

Has anyone tried this? Not inexpensive but looks like a good option if you want some flexibility.

I believe we can thank the high end motorcycle market, led by HD for the high prices. The market appears ready to pay $20-$35K for high end motorcycles. Conversely high end snowmobiles and...

Let me know if or when this might be happening. I can offer some tips etc about travelling up the Alaska Highway, particularly through Yukon, my stomping grounds. A few of us might join for part of...

This is true up to 5000 rpm. After that the stock system becomes progressively restrictive under WOT to redline. I consistently measured it at over 3.5 psi. A Two Bros exhaust, in comparison,...

Even when you have the right spring pull tool, the problem is that there is not enough space to pull the spring out and away from the pipe as you stretch it, so it catches on the edge of the pipe. ...

Does seem weird. Maybe BRP increased the level of traction control for the standard mode setting on models with the Sport mode option (?)

The system's traction control will limit wheel spin unless you're at 90%+ throttle. There it will allow you to spin to redline. As with many things in life, the solution is "more throttle".

A while back I was able to test the stock exhaust for back pressure. ( http://www.spyderlovers.com/forums/showthread.php?98322 )

It's been cold here for a while but finally got a chance today to...

Used to be I'd buy every manual I could for my vehicles, like Chilton and Haynes etc. Now I download the service manuals and just google or search youtube for specific issues. Lots of tips and...

It is an issue that requires attention, so it might annoy some people. But I agree that the fix is so minor that it should just become part of regular maintenance.

I was part of the crowd that...

Had a chance to make some runs today with my F3 stock exhaust connected to a digital manometer.

I can tell you unequivocally that the stocker flows really well....up to about 5,500 rpm. Idling...

"For a performance comparison he cited a highway curve with a reverse camber signed at 40 or 45 mph near their factory. A two wheel Wing, and the conventional trike, can take the curve easily at 65....

After a lot searching and comparing pictures I've found that the Can Am Fusion helmet is a rebadged Lazer Kite. It appears that Lazer no longer offers this model directly so BRP must have an...

Hopefully the sport mode is coming based on other threads.

Just ran another autocross today. This time with a BajaRon swaybar and two bros exhaust but still a second + off the pace of the...

Had a chance to play a bit with the stock exhaust vs Two Bros. Gotta say that the stock exhaust is not that restrictive even with a cat and constriction of the pipe down to 1.5" at the secondary...

I've just put my exhaust on and off a couple of times and then installed a two bros (doing measurements etc), so got pretty good at removing and replacing the springs. As others have said, it helps...

I've got a wide band o2 sensor and air fuel ratio data logger. Going to see how the current ECU is tuned and if or how it reacts to various exhaust configs from stock to a complete new system with...

Add another. ;) Ready to start fitting and measuring various exhaust configs.

I'm working on some performance calculations. So far, haven't found this spec in the service manual or online. Does anyone know the rod length c-c of the 1330?

thx,

I have the gear to do this along with any back pressure changes. The only thing I'm missing is the baffle. Would be great if someone could loan me a baffle or provide me the measurements so I can...

I'm interested as well. Right now I'm looking at adding a Flowmaster Super 10 inline with my TwoBro's exhaust. It's called a muffler but basically is a chamber with some deflectors to direct the...

I'm thinking a small resonator in place of the cat would be ideal. Lower restriction, smooth out the high exhaust notes and keep any pulse tuning that might be in place.

Gutting the cat would be...

I guess helmet choice usually boils down to a personal view of form versus function against price. Ive got about a half dozen helmets kicking around. Some definitely have to be retired. I usually...

Does anyone know the manufacturer of this helmet? Any users? I'm trying to determine how quiet it is...

thanks in advance.

I just replaced my first at 4600 kms (2600 m) . A little too much throttle on take offs I guess...will try to do better this time ;)

I've taken a look at the Bosch sensor spec sheets and the F3 wiring diagram. As it stands now it appears the various sensors on the Spyder provide a normalized voltage (typical 2.5V) to the ECM. ...
