Engine to tank clearance rule?


Recommended Posts

Question on recommended clearance from the top of the valve cover to the bottom of the tank.

On my B12 zuma, the gap is smaller than I'd like, <10mm. I'm imagining in some worst case scenario, say I forget about this and in a year sling a heavy tank bag on there, it could contact, and hot engine directly contacting a metal tank would be bad news. 

Is there a rule of thumb for this in terms of clearance? Plan is to space the front mount up with some rubber strips to gain an extra few mm - does anyone use any heat reflective / insulation material in applications like this? Am I worrying too much as long as there's some fresh air there?

As long as there is fresh air between the tank and engine you'd be ok unless your rubber are very soft.

I've seen some race bikes use heat reflective tape/ insulation on tanks but this is more to keep the fuel cool for better performance.

If you're worried about it, there is no harm in lifting the tank.
