Removing my exhaust system and studs are pretty bad, I wanna fire up the bike to heat up the block and maybe loosen up the studs. Its the safest way that I know to bring the temperature up there.

Is there any risk in firing it up without any exhaust system or sensors hooked up?

You never know with these new ECM ran engines

My first thought would be your valves and stems. With out the exhaust they could warp from cooling off to fast.

 

i see no issues. if efi, you will throw codes but at least you know where they came from. ever lose an exhaust pipe?? yep been there done that, drove home 25 miles with front pipe across my lap, it does sound sick and i do not mean in a good way.

 

In the old hot rod days, we would stuff a rag up the header to keep cool air from doing that when we had the pipes off.

 

 

Got It out thanks!

 

How?

Your run the bike or use a torch?

 

Didnt run the bike. Gentle heating of the stud with a torch while monitoring head temperature with my finger. Then cooled the stud quickly woth a can of liquid air for dusting computers ans BAM!

Hahaha

 

The appliance of science! Well done.
