Hi all,
So my sliders are installed - 20g weight (from buggyparts of course) and here is the result....
et voila - lower revs at cruising speed! Which was my main objective.
In a normal tank load, I am increasing my average mpg to around 58 or so from 56 or so. Not a huge difference but here are the important differences:
1) Off the line, and around town - slightly zippier. Not as much as with a Costa Variator (what is?) but slightly more pep. Slightly faster mpg drain out the exhaust too to be fair..!
2) Once up to speed, around 45-50 mph is when you see the real difference - the revs start heading in reverse... Very intriguing!
At a steady 70, on the flat (and here that context is crucial..) I am turning over around 5900 revs. Which is a real difference in the thrashing of the poor engine.
I feel like torque drops off quite considerably, as the rev band is narrower now with 20g weights. I do not think the engine has the grunt to exploit a higher top speed. On a flat, or a downhill, the engine will scream and labour less, which is nicer. Although why you would want to go much quicker than around 85mph in the thing is anyones guess. The engine at least will rev less - but* in a chassis that is about as tough as a cream puff, speed is not the burgman's friend...
*not up a hill - the performance with these sliders deteriorates rapidly going up hills - the torque band has dropped off a fair bit - once you get up to speed, hold the speed if you can, but it will not rev out like the standard rollers.
Overall, despite the negatives, I am very much sold on the 20g weights. Why it doesnt come like this from the factory I do not know.. its far more civilized for my use, and much more peaceful to ride. Each to their own. Personally I recommend it, unless you have a lot of hills - in which case it will drop off performance and mpg.
