Engine braking... any hazzards engine wise?

[John 675]

Other than locking the rear wheel is there any long term damage you can have by using the engine braking, i say this because i always use it, if im coming up to a set of lights that are red, i will slowly cycle down throught the gears to 2nd before i start braking, then i usually clutch it then stop and change to first, but i find the egine brake doesnt upset the bike as much as the calippers do.. can using it bugger your engine?? :confused:

[Dangerous Dave]

No, otherwise all bikes would be fitted with slipper clutches!!!

[dizzyblonde]

don't worry engine braking is fine, V twins do a lot of it

I was told that engine breakig on my RS125 might have contributed to the top end going, any truth in this? I was warmed up and ridden in the powerband all the time, only way to ride it!

[Alpinestarhero]

Yes!! It'll kill the world and all the universe!

Actualy, no, its fine. Although, apply the brakes a little so you signal to others that you are braking; the SV engine braking is quite strong, and I do the same as you - throttle off and go down the gears. Its as effective as using the brakes on other non-vtwin vehicles (excluding big singles!)

The only thing I was told is that using engine braking wears the clutch/chain/gearbox more and as its easier n cheaper to replace brakepads its better to use the latter. Makes sense dont it.

I agree with ther above comments, however you have to be sensible with the changedown. Extreme example: Going from 6th at 70mph straight into 2nd, don't think you'll get it into 1st, and you bend the valves and possibly see your pistons at very close hand.:laughat:

But especially in the manner you describe lylej, not a problem engine wise IMO.

sweet to know, as the engine baking has and probably will again saved me from prangs.. IL4 pfft.. aint got nothing on twins lol,

No, RS125 engine is really a petrol powered hand grenade.

[John 675]

+1 lol, it is just a matter of time on them machines lol,

There might be something in this.

No throttle means no lubrication. I don't think it would matter though unless you were engine braking for a very long time, like dowm a very long hill.

Any 2 stroke experts on here?

So long as you downshift smoothly then there's not a problem, why would it wear the clutch out, if the engines slowing you down then the clutch is engaged.

Just don't crunch through the box like a monkey, it should slip in when you blip it to the right revs

Also a 2 stroke still has lube at idle, if it's got an injector pump then it'll still feed it oil.

I often see monkeys riding bikes like this. They should stick to things they know about, like peanuts and PG tips ad work...

haha :D

RE the RS125, yes. It's not recommended to coast on the over run on 2 strokes as there's no lubrication for the mains and bore. Manufacturers advise keeping the throttle open partway.

[flymo]

there is a problem with this. If you down shift too early to the point that the engine revs very high then you can cause serious damage. Remember that the rev limiter only works by inhibiting ignition and so offers no protection at all if the engine is mechanically driven too fast by the back wheel.

Provided that you keep the revs within a sensible limit doing this then you should be fine. I have seen a bike on track spew its guts out as a result of very high revs in a downshift though.

No truth in that.

There's very little extra wear on the chain and no extra wear on the engine/clutch/gearbox. You wouldn't notice a single penny of savings by not using engine breaking.

It is true

...and as its easier n cheaper to replace brakepads its better to use the latter. Makes sense dont it.
Partially true,but as long as you keep downshifting at a reasonable rate(not easy,it feels great!!:D:D:D) and as long as you don't cause overreving due to downshifting,you will never replace an engine part because of wear/damage caused from downshifting

Just keep an eye out for Sheriff Rosco Coltrane...

Other than that you should be fine;)

It's funny how one get's used to the vtwin braking; driving a 4-cylinder feels odd as you need to remember to really grip the brake when slowing down. When I changed my rear tire the mechanic just looked the old tire and said something about vtwins eating away the rubber with the engine brake...
