Hi

Is it normal for the BEC transmision to be so clonky. When i put it into gear it clonks, and when im on slowing down or when im going slowly/on and off the throttle it all sounds a bit clonky.

Everything is bolted up nice and tight.

When under power and acceleration everything sounds fine, but even then gear changing stil sounds clonky. I know bike gearboxes usually have this clonky sort of feel, and that with the fact that the diff is bolted solid, is it just a case of evrything being amplified?

your thoughts much appreciated.

Thanks.

PS some better Pics for those interested.

Have you got a torque resilient tube prop fitted (or some other form of cush drive)???

Might be worth the investment if not as your transmittion will have a much less stressed life.

pretty much spot on mate, the prop and solid mounted axle amplify the noises through the chassis tubes. just learn to ignore it
the initial 1st gear clonk is normal but if you depress the clutch for a few seconds before engaging 1st gear it will reduce it some what, Bikes have a cushioned drive to deal with this but still clonk into gear

i have used the rubber mounts on my diff which has made the driveline much quieter than my previous BEC

Oh yes

Much clonking!!

Tends to happen mostly at low speed or, as mentioned, the 1st to 2nd shift.

Answer is to keep going fast

Then again, I've got no cush-drive at all!! Might slow down the 0-60

your driving in a tin can, what do you expect? It's like my neighbour panicking at the slightest noise his landy makes - It's a flippin landy not a car!

My R1 used to be a bit clunky going into 1st, I slowed the tickover down, made a big difference. 1st to 2nd is noisy on my mates bike, but mine's ok, had his from new and its always been like it, so I wouldn't worry.

The prop is one supplied by MK, and its got a rubber mid section, butimnot sure what the cush drive or torque resiliant thing is you mention.

Hmmm.... sounds like a serious problem, caused by a light right foot and too much exhaust silencing.
