With Spring in the air a couple of weeks ago I decided I needed something or another
& would take advantage of the sunshine to ride the Beeza.
About 10 minutes into the ride I was cruzzzzing along at a very respectable 70-80Kms
when out of the blue .. BOOOOM... she back fires & splutters to a hault.
I quickly check plug leads are on...
Fuel is on...
try to restart... nope... just a back fire again.. ahhh haaaa.... TIMING says me...
so I push her into a drive way & ask can I leave her there while I go home to get my recovery vehicle.. ( Rescue One )
A couple of days later after checking for spark @ the plugs, points & maggy, fuel, I did a compression test...
Ohhhhh Nooooo..... ZILCH, NADA, NOTHING on the Left Hand pot...
I removed the L/H exhaust header to discover the exhaust valve was stuck open..
After confering with Musky & Brian ( THANKS lads ), it became obvious that the valve had nipped up in the guide...
Due to heat expantion of the valve stem... & not enough play in the guide.
Simple fix says me... hahahaa.... nothing's simple... it appears that the valve must have just kissed the piston & is bent.
( possibly during one of the 3,428 times when I tried kicking it over )
Luckly a new valve was obtainable from Modak...
I took the head back to the company which did the valve seat grinds, & reamed the guides last time, to show them the damage,
they were very understanding & agreed that there was not enough clearance in the guides, so would re-ream ALL guides again for free.
Now for the rebuild .... again...
Soooo... moral of this story is...sometimes a little loose is better than too tight... Size
DOES matter...
