Primary chain keeps slackening up
Had to adjust my Primary chain - ( Tin Primary ) twice last summer
Now while I have the bike in pieces again I am wondering if I have done something wrong that the chain keeps slackening up
I have read prior posts on a chain tensioner.....maybe I should install one to make up for some slack?
Any suggestions on what style to order...don't really want to weld a bracket onto the frame

Re: Primary Chain
kb
couple of thoughts before you modifiy.
chain getting enough oil?
not running it to tight?
using a good chain?
nothing bent, worn out or out of round?
if it was new when you installed it sometimes they take a couple of adjustments before settling in. after that they are usually trouble free unless they do not get enough oil.

Re: Primary Chain
I tried a couple of Diamond chains and another brand Tsubaki??
All of them required constant adjustment. Everything was lined up correctly and there was plenty of oil being dumped from the CC vent directly to the chain----
and my rear whitewall. Even tried new sprockets and new chain.
I went to a belt and never looked back.
Now it only takes me 5 minutes to adjust the rear chain.

Re: Primary Chain
Ya...Changing to Belt has always been a thought....But a few things have held me back...Cash being one
The chain is getting oil from the breather tube....Although it may not be enough
The chain has a rusty brown looking oily dusty color to it....I thought it was Clutch dust?...mixed with oil....
Also just noticed today that the left Rear engine mount was loose....

Re: Primary Chain
KB65!
The most common cause for a chain going slack prematurely is to be too tight in the first place.
If the chain alternates from slack to tight to slack again, the chain has "stretched" from eccentric sprockets.
65s should get far more oil than previous models, however they also get more water!
Depending upon conditions, the source of the water can be condensate within the housing, but usually it is water drawn in by the vacuum.
It took the Factory several 'updates' to mitigate this problem: Be certain that seals are in place behind the solenoid, around the starter shaft, etc.
Good luck,

Re: Primary Chain
If the chain turns brown it's not getting enough oil. I like the belt drive too but the chain is more reliable, (I've never had one break!)...Mike

Re: Primary Chain
At risk of sounding like Mr. Shift by disagreeing,
Brown all over is rust. That's why I brought up water, particularly for a '65.
One hopes that the oil will prevent it, but often the climate, distribution of the oil, or even lack of duty allows it.
Otherwise, a dry chain gets hot enough to turn peacock colors. One of them is golden brown no doubt, but it doesn't come off on a rag.

Re: Primary Chain
If you must adjust a primary chain weekly, your either riding hard twelve hours a day, seven days a week,.. or you've got other problems!

The difference between me and you is I learned from my mistakes.
