How are folk getting on with the chain drives in their Midi's?
Any problems with chains jumping off sprockets, or shorter than intended chains overheating?
Also, how do you take up the slack when the chain stretches?
Cheers!
I hate chains, mucky things
next bikes going to have a shaft drive
"Also, how do you take up the slack when the chain stretches? "
With a chain tensioner.
Been running chain drive in race cars for several years, with the exception of a chain that failed on first run due to a fault in the chain we
generally don't have problems with the chain.
The down side of chains is lubricating them and guarding to prevent an excessive mess from the chain wax. For race we wax the chain after 30-45mins of
running.
We run chains around 78 link length so signifcantly shorter than on the bike, and on the latest car there is very limited airflow around the chain, we
have yet to encounter any issues with excessive chain temperatures, I suspect this is likely to only really become a problem if the sprockets are not
correctly aligned or the mountings are not sufficiently stiff to maintain alignment under load.
Our car like most others moves the differential to tension the chain (via 2 turn buckles in our case), with good quality chain (we use DID ZVM2) re
tensioning is generally only required after initial running, we normally replace a chain after a complete seasons racing and testing.
The smallest front sprocket we have used is 15T (normally 16T) so I cannot say whether the above would stand for smaller sprockets (and therefore
higher chain load)

Thanks for that Ian... pretty much hit every nail firmly on the head!
