2500 bucks to rebuild the engine

[partireper.it]

Who told you the engine needs a rebuild?
Why did they tell you this?
110,000km is nothing.
Is high fuel consumption the only problem you are aware of ?
Get a second opinion
You dont want to be rebuiding the engine to fix a carb problem.
Unless it uses oil as fast as you can put it in or makes great clanking and clunking sounds, assume the engine isnt knackered.
good luck

so, in a list of checking to do in order to sort all that out, what would you suggest me to do?

First things first -- go and get a compression check.

Post up a thread asking if somebody in Christchurch will lend you a compression gauge. It's a 5 minute job.

Then post here what result you got.

what category would you post that in?

[Ixion]

Agreed. Costs nothing , takes only a few minutes and gives a lot of info.

In this thread, or start a new thread in the Engine - Clutch - Transmission forum

Before running off half cocked
First things first,
What problem are you trying to solve?

or in other words
Why do you need your engine rebuilt?

I recall mention of high fuel consumption, is that the only problem?
Aside from that does the bike still run OK?

+ 1 for that, could just be a chocked air filter

If all else fails, im a fan of buying a low mile motor to replace an in need of rebuild one, usually costs less

ok, let's say that in september, in december and in february, i've tried to fix this fuel consuption problem by changing all you can think about

air filter

oil filter

engine oil

spark plug

carburator

new clutch

valve tuning

carbi tuning



still the problem is there

high fuel consumption. strange noises in the engine

black spark plugs

dirty exhaust tube

bike still runs ok. it gets flooded pretty easily though and smokes more, but you can't tell anything more by that.

i thought about the rebuilding because is the step to do, but i haven't done a compression test yet....

Maybe you should get it to a competent mechanic (where do you find one of those? I dont know)
He will be able to tell you if the black plug and black exhaust are fuel or oil related.
If fuel related than more than likely there is something in the carburetion side of things that is the problem.
Dont assume that by buying a new carb you have eliminated carburetion problems.
If its oil related than yes you may be heading for some mechanical repairs.
Are the noises new? If they have been there since you have had the bike I wouldnt worry about it.
They didnt turn up after you fitted the new clutch or carby did they?
The mechanic should be able to give an indication of what the noises may be
Good luck

in december, my bike (dinosaur as they called) has been fixed by Honda Australia MPE. They offered that service and genuine parts. But had no time to open the engine.

they did the rest, but the bike does what i wrote even now.

im looking now for a compression tester to post here the result!

For a (better) second opinion,take the bike to Dirt Action Services in Saxon St,see Phil there & he will tell you what you need to know,with no punches pulled.These guys deal with dirt & adventure bikes,like yours daily,so if I was to trust anyone with my $$,it'd be them.
