    After lifting my bike upon the work bench and turning to grab the old 10 mm wrench, Shazaam! It fell on the floor hitting several machines on the way down.
    Question; After this it still runs great but do you think the engine will have a hot spot and sieze without the cooling fins and is there any way to make it better? (Like an aluminum bandaid!).

    isntall a small computer case fan to blow on the area? LOL

    my engine is always hotter on the left side than the right. I may do some fan thing, no matter how cheesy it may look.

    Ha! Ha!

    Well maybe if I brake in the otherside as even as this side it will all balance out! Not! :???:

    doggone, that's bad news.

    i'm thinking it'd prolly be alright, but i wouldn't idle at standstill for long if i was you.

    Good idea

    I agree not to stand still to long and just maybe it's time for the hillbilly coffee can induction cowl especially formulated with giant hose clamps.
    Hey if it works and it's cheap, let it roll!

    I just noticed that your engine is incredibly clean! even the edges of the fins are nice and straight. Everythings so shiny and new looking.

    Mine looks like it was molded very badly...

    look at the intake gasket, the engine's brand new...give it time :p

    while this topic's been going, i keep looking at my bike trying to mentally engineer that cowl, too 8)

    Your right, this motor has maybe a total of 10 miles on it.
    Tell me when you get that induction cowl designed for me.
    Got a good deal on this engine kit. $153.00 with shipping. (Ebay)

    take it to you local welding shop and have the old fins tig welded back on P.S, tell them to tac it only no welds over 3/8 long

    You were talking Augie about how nice the molding was on this engine so I will tell you it is a Kings, which is weird considering alot of the members here think that King is the worst but the fastes.

    I think that

    From What I see.......I do not see that you lost too much. You should have no worries. These are low compression motors. they do not run super hot after break in. You will be fine. The damage is more cosmetic than anything. No big deal...

    Thanks for the input Dax. You would probably be the one to know since you have to deal with motorbike poblems every day.
    Hey maybe I could be a hillbilly and wrap copper tube around for a heat sink? He He!

    leave as is ...

    dont think loosing portions of fins will affect overall performance

    this'll do it

    sneeze so hard so some of your brain comes out. hopefuly the part you damadged while damaging the motor....
    STEP 2 mix said brain parts"aka gray matter" with J-B weld
    STEP 3 form new fins with newly formulated "I can't beleive it's not my brain making my bike go faster" compound ......and enjoy! only your relatives will be able to appreciate how fast your bike is........after they have sent you back to your room and ridden home with it !

    Step 4: ask if anyone has spare cylinder assemblys lying around.

    Seen plenty of old lawn mowers missing fins and still ran fine. I think you will be fine!
  17. You know,you very well may have something there.
    Copper being a good conductor of heat can serve as a heat dissipator if you can somehow run water or antifreeze thru like a small radiator,wrap the copper tubing around the head and get that fluid to turn by a water pump attached to that Happy Time PTO kit I saw Dax sell,then you would have a liquid cooled Happy Time!

    I've actually seen copper tubing (the size that is used to feed your icemaker in the kitchen) cooling system that was neatly wrapped around the cylinder head and pumped by a small electrical pump to an oil cooler that was converted to use as a radiator.

    It wasn't on a motorbike but on a different application. I personally wrap copper tubing around glow engines so I can fly them in the winter. The copper tubing in this instance helps retain engine heat so the methanol/nitromethane fuel can properly vaporize.

    Thats a really good idea! You could just run the coolant pump off of the drive chain? Small oil cooler and copper tubing, then bam! water cooled engine (kinda)
