Another "My bikes got a problem" Thread

[EJK]

Yep, I got a call from the Colemans Suzuki this morning.

Where do I start...

I thought the bike only had a problem with the carb but it turned out to be something more serious...

OK, colemans called me and told me about the problems:

• Messed up cylinder head (dunno about that)
• Low compression ratio. Got a leak or something...
• something else... I forgot

I'll edit the list when I get the full details.


So its the engine which as the problem and it'll be expesive to fix

OK, since this is another of "Fuck! Another problem! I need help from KBers!" thread, I'll need some suggestions...

So far I thought of

• Selling the bike as it is on Trademe (like this)
• get a new engine
• fix it from Colemans ($900, I don't think so tho)
• and thats it

Hmph!

Doesn't sound too good there EJ! Hmmm selling it as is you definitely wouldn't get much for it huh, maybe check out any wrecked FXRs for engine parts ie just get a new cylinder head. Surely it's not hard for Colemans to find the leak and chuck some sealer on it?

[EJK]

I was thinking..... yeah....

So far my best idea is to get a new engine from somewhere...

[fireball]

i hate to say it but.....

I TOLD YOU SO!!!!!!

best option EJ is either get a new engine or (if its insured and rideable) crash it and claim it....

EJ--dude its a lil single cylinder suzuki FFS.
Unless some cowboy has run it outa oil I betcha the problem is its burnt a valve so has low compression.
Not exactly a hard or expensive job.

So.... Colemans were lying? lol

I'll get the full detail by tomorrow...
It was a short phone call so I couldn't really tell you guys what the problem is heh...

No. A burnt (or tight) valve will cause low compression (wot they said); and could also be described as "a messed up cylinder head". Or, it could just be a blown head gasket. Or y' hamster's got an attack of the squitters. Mr Frosty's guess is more likely than most.

Ask Coleman's to be a bit more technically specific - especially about the "something else - I forgot". "Something else" covers quite a wide territory.

I'm on it

[FROSTY:Me]

sorry dude i'll rephrase-ok so a valves buggered it, needs rings (unlikely)
the top of the piston needs a cleanup and maybee the head is a touch munched---covers off all the likely senarios.
$900 for a shop sounds about right to azllow for an ass covering fix--as they have to do.
BUT--I bet moren half of the cost is labour---of course
No matter how flash its only a gn250 motor FFS
why not rip the donkey out -its a single so much easier to work on it on the bench--then haul the head off yaself.
that way you will definitely be up for the price of parts but labour can be reduced to the cost of repairing the valve damage etc -Not the strip/rebuild costs
--Shoer version--do it yaself

[EJK]

Someones gotta show me + teach me on those

Edit: Seriously I suck at these...

Helped Stephen the other day take off cylinder and engine heads, wasn't too hard. The 2nd GN only took about 20mins to take both off. . Do you have a manual? Because the bolts need to be taken off and put on in a special order.

[FilthyLuka]

if its like a gn250, you probably dont even need to take it out of the frame. I did a complete top end rebuild on mine with the engine still in the frame.

Whip the head off, have a squiz. If something is munched you should be able to see it...

Talk to colemans though, if its just a fooked head gasket then its not really a problem aslong as the head is straight...

[EJK]

Anyone know where I can find a Manual for the FXR?

[Kickaha]

A leakdown test should show which of those options is most likely

[Ixion]

True. But with an FXR150 you could probably whip the head off in the time it took to do the test !
