More engine braking with 351?
Since putting in my BB 351 kit I have noticed (as well as a buddy with a stock KLX) that when riding the bike in slower technical terrain the on/off throttle response is more abrupt. Fine when under power but as soon as the throttle is closed there seems to be more engine braking making for a jerkier ride. Kind of like some fuel injected bikes it's either on or off.
Has anyone else noticed this? Other than this one observation the 351 is fantastic! |
Bigger piston, more engine braking, what would you expect?
My 650 single will slide the rear tire in 2nd on pavement trying to bump start (with a big bum drop), HELLO! |
Welcome to the world of riding big bore singles.. My Husaberg 650 will throw me over the handlebars if I stall it..

bigger piston = more compression = more abrupt engine braking, right!?
|
Besides more power the engine braking is the next feature I like with the 351. I use stock gears and I run in 2nd or 3rd gear on tight trails and use the engine braking for most of my slowing around turns. Even on the road I like the engine braking to help get me stopped.

Yes, I expected there to be more engine braking, just wondering if others that have the BB had the same experience.
The huge increase in fun factor is so worth it! |
I will be able to tell in a week or so once I get mine installed. Since a bigger slug should draw more air at idle throttle opening, and the BB351 is reported as having a higher compression ratio doing more work compressing the idle speed air charge per revolution, relative to the stock engine, it follows that greater negative acceleration would result.
