Hi Guys,
Just got a *cheap* 09/1999 FE400 with an alleged ignition fault. Found a broken wire on the coil pack and voila good spark restored
A 12mm plug has been bodged into the head, so a heli-coil back to 10mm needed.
The real bad news is... still no starting or even a fire off ether and a bizarre compression "rock" when you kick the thing which is explained by...
Further teardown shows both intake adjusters have snapped at the rocker, one of which has gone under the cam and been punched through into the coolant passage underneath the camshaft bath leaving a 20mm hole. Crap. The intake rocker arm roller has collapsed as well.
One broken adjuster found in the hole with a chunk of head, the other I suspect has been removed by PO when he found it was an ignition fault. LOL.
So head off and into my machinist, his welder isn't good enough so off to local radiator guy - no problem. Quoted $60 to weld, no problem. The guy is good, has welded alloy swingarms and suspension linkages for me and others before.
Everything else up top looks OK, no damage to cam and timing chain is tight. So I pulled the barrel, the rod, piston and bore all visual OK, so I am thinking a light hone and a set of rings.
For the top end 2 x adjusters and the rocker roller, with a head service.
What I believe has happened is the rocker roller has seized then collapsed, causing the intake adjusters to get loaded so they snapped causing the other carnage. I suspect from lack of valve adjustments by PO.
The bike has been ridden hard but looks like it has been well maintained until this guy got it. I don't believe he was capable of maintaining it either.
I also pulled the clutch cover and no sign of the missing adjuster or any metal, munch marks etc. I do not believe it could have got into the gearbox area either.
Inside of engine is very clean indicating regular oil changes although some fresh water contamination (expected)..
My questions are
- Do you guys with your experience of Husabergs agree with my conclusions or am I missing something else?
- Should I replace both rollers and all valve adjusters and valves as a precaution?
- Anything else you can think of?
Rest of the bike is pretty solid, just a bit ratty from 15 years of use.
Thanks in advance.
Waldy
