Fitting sensor in beancan

[paulh]

Hi, can anyone tell me if the engine needs to be set in any particular position when removing the beancan to fit a new sensor.. TDC etc or are there any timing marks i need to take notice of.?

Got the sensor a while ago but only just getting round to fitting it

Cheers.. Paul

Swapping in a replacement bean can is fairly simple. And the Airheads are not overly particular as to exact position to get the engine fired up for timing.

When I remove / service / replace the cans on my R65s, I use a marker to put a dot on the bean can mounting lugs and another adjacent mark on the timing chain case. That will get the can close enough.

After a warm up ride, check ignition timing with a strobe. Bet you will be very close.

BTW, where are you and what model year R65 do you ride? Post up a photo so we'll all know the bike really does exist.

hello

sorry if this turns out to be a hi jack BUT whats the bean can on an R65?

I read in another thread about a view hole near the bean can but where is the bean can??!!!

thanks

When the R45/65 was introduced in 1978 the points together with the advance mechanism were put inside an ignition canister driven off the end of the camshaft. All other airhead models which previously had traditional points on a backing plate were also fitted with this ignition canister at about the same time. In 1981 the points were replaced by a hall effect sensor and remotely mounted electronic ignition module but the ignition can still contained the mechanical advance mechanism and the exterior looked much the same. The oval shaped view hole can be seen on the top it's just a pressed steel cover that can be prised off to give access for lubricating the advance mechanism.

The ignition canister is about the same size and proportion as a can of beans hence the nickname.  You'll find it under the front engine cover. Picture below is the points version.

If you choose to check out your bean can, do first remove the battery's negative ground cable. It is quite possible to make contact with the front engine cover and the always electrically hot portion of the diode board, fry same and then spend some time cussin' like a sailor.
