Title: Testdrive: Luck is not on my side...
Post by RobSchneider on 05/07/13 at 23:14:06

Well, as you may have read, I did the plugcap-leak reparation a week ago. When I put the cover back on I noticed that two bolts have been too tight (previous owner) and therefor trashed the thread in the engine a bit.

I tried to tighten them as much as I can, and put the bike back together, including a smaller jet because it was too big.

The next day I want to testdrive the bike, so I took it out of the barn, and tried to let it run. When I pushed the start-button it did come alive after a few seconds, but as soon as I touched the choke, the bike shuts off.
I tried to start it again, until I saw a small puddle of oil, and a small puddle of fuel below the bike... %&%&*^@%^%!!!!

Turns out the oil-leak is not solved, and become even more aggressive,   I hope that the fuel-leaking (it was pouring out of my K&N) is just because I tried to start it too long, and it drowned in fuel... (someone can acknowledge?)

So, back to the drawingboard, I guess I have to put in two helicoils after all, going to search on this site howto dismount the engine... wish me luck guys!

1.  Man,.. I wish I had a barn!... 8-)...
2.  Are these head bolts,... or head cover bolts?...
3.. You did use some rtv sealer when you put the cover back on?...

c...  When I use choke (enrichment),.. I put it on before cranking the bike... because it is a cold day...
...(temps above 75f or so,... you usually don't, or shouldn't need it)... this varies some, depending on overnight temp changes and elevation... but, it don't always need choke... only in cold weather...
...( I explain these things, not assuming your experience, but also for others reading)... I don't know your experience...

Soooo...
Why, are you adding choke after the bike fires?... Is it cold outside?... is this a routine?... is it stumbling?...
Summertime... you likely don't need choke...particularly,.. if it fires up right away without...

...and finally...
You might try this,.. it's worked for me in the past...  
In the stripped holes...
Buy a bolt, at least 1 inch longer than the original one,... and thread it down as far as it will go...
Then, check how much further it goes than the stock one...
You may have an extra bit of threads to bite on, that the stock bolt can't reach...
If you do,.. just buy a bolt, slightly shorter than the full thread depth, and see if you can get it to tighten down...
It ain't perfect,.. but, it can last the life of an engine, if there are no problems that require r 'n' r of that bolt too often...

Best luck,
Serow

Yes, I would like a bit more... and if possible, with pics.

I did use sealer, did it all according to the manual and various topics on this forum.
It's the headbolts, I already used a longer screw, but cant seem to get it in any further unfortunatly...

I didn't make any pics, because I don't want to remember that moment... :(

Will post some pics when I'm going to get it apart again...

So you guys think the fuel pouring to filter is normal?

Title: Re: Testdrive: Luck is not on my side...

in your Savage learned fuel in the air filter? of course, this is NOT normal . you need to parse the carburetor and check the shutoff needle and her saddle and even check the status of the darned fuel petcock.

It sounds like at least one of the bolts you are having trouble with goes into the passage that brings the oil up to the head.  It either is not tight enough, or the sealing washers are not sealing.  (You did put the sealing washers on the correct places?).

If the stripped bolts are in the oil passages....you are going to have to take the cylinder off to fix it right.  You are going to have to flush out the metal bits from the helicoil repair work.

If taking the engine out is an issue.....it is possible to loosen the engne and tip it in the frame to ge the head and cylinder off - but it doesn't necessarily make it any easier.  I much prefer having the engine up on a bench to work on it.

I repaired a '96 that had 2 stripped head bolts...
Put it on the bench, helicoil them (wasn't as scary as I imagined but go slow), check the seal on your plug repair, torque the head bolts and button it up...

Just watched a Youtube video on helicoil.  I had no idea what it was, learned something new.  I love this Forum, and Youtube is such an amazing resource.

Rob,

Which jet did you change out?

I did have the washers on, but will double-check that!
But the stripped threads are the ones with the long bolts, so I guess I have to go and helicoil it after all.

The stripped threads are L125 & L130, on the right side.
i noticed that the L130 leaks, the other one is dry.


@digger
I have a K&N, harley screaming eagle muffler and went from 165 (which worked but too rich) to 160. We're 7ft below sealevel.
Stock is 130.

you can also try to apply sealant for the bolts m...Yes... it is difficult to treat the patient "on the phone"... :(

I think the bolts are M6 0,75, right?
I can't seem to find any Helicoil-kits for that size, I can find them for M6 1,0.....

The head bolts are are the standard 6x1.0 I believe.  I will check the bolts tonight to be sure that they are not a different size.
