Dr Pulley Rollers 16g - Holy acceleration Batman!

Post by **Funkycowie** » Mon Dec 24, 2012 8:54 pm

Put Dr Pulley 16g rollers in last weekend... acceleration is increased, the clutch bites quicker, not sure if the mpg has improved because I have been enjoying the acceleration a little too much if you know what I mean

The difference is very noticeable

I haven't found ther MPG to be affected at all on my X9.
It seems like it should be, but I think the lower gearing during acceleration means that as long as you aren't hammering it all the time, it is working less hard therefore using less fuel.
The extra performance if used will cost more in fuel, but if you ride as you did before most of the time, only using the new 'boost' occasionally, you won't see any higher cost for fuel. 58-60mpg is still average for commuting on my yellow X9 with the 8 roller 16g DrPulleys, and the white X9 with stock 6 roller 28g DrPulleys only does 50-54mpg although that ECU is still the older mapping too.

Sounds great! I'm gonna fit the 15g ones hopefully in April. It'd be interesting to see the difference from stock.

Got my Dr Pulley Rollers and sliders the other day, just waiting on the belt, and some warmer weather...
