    The blower motor on my  Tiger was running slow at one time.  I found 
that the motor was drawing  over 1 amp.  The motor bushings were seized to the 
motor.
I cleaned the motor shaft and lubed the  bushings.  The blower ran much 
better and only drew around .1 amp.   I don't recall exactly what the final amp 
draw was, too long ago.    Checking the amp draw is one way of checking the 
motor/ bushing  condition.
 
    The heater core is  sized nicely IMO.
You have to check that the core is not  plugged - I back flush the core now 
and then to get the sediment out of  it.
The air has to go through the core not  around it for it to work correctly.

Hello,
 
Though my Tiger 1A is tucked away for the Massachusetts winter,  thoughts 
of improvements/fix-ups still pass through my head. This question  is about 
the anemic demister/heater system.
 
Two components make up this system
1) the blower with the squirrel cage fan
2) the heater radiator
 
The blower fan seems like it could use a redesign. SOOOO slow.  Mine is 
working same as it ever was. Anybody tried  upgrading this?
The radiator seems awfully small. Any smart-guy thoughts on this?
 
Anything else I should be thinking of? Any Ideas?
 
Even if the heater isn't regularly used, I'd like to be able to count  on 
the system to defog the windshield.
