very true. I would check:
- if your brakes are not sticking (try putting the bike on center stand and turn the wheels, should turn freely)
will do - but doubt it have major infuence on consumption- clutch adjustment
chain is in good shape- chain condition (check for hard, locked links)
I believe I have damaged diaphragm in petcock, but I can't find proper one - i think previous owner changed the fuel tap - I have diaphragm looking like square+triangle, but in every repair kits I see square shaped ones. Still - it can be part of my problem I guess, but its not completely damaged so the leak isn't big I guess and goes directly to carbs - not outside.- fuel leaks (around your carbs, petcock, tank area)
sync of carbs doesn't influence on consumption- air/fuel mixture - make sure your valves are in spec, your carbs are synced and well adjusted
My mechanic friend said that this is setted once in electric starters and there is no reason to re-do it - he is wrong?- timing (see manual)
I must do compression - but still I think it would rather do poor engine performance than actually bigger fuel consumption :/- compression (maybe your piston rings are worn, maybe you need a rebore)
that is my huge problem - my center stand is worn i think Bike stays with 2 wheels on ground when its on central :///
If your clutch is not grabbing on well (slipping slightly) you'll have to open up the throttle further to get to the same speed. Maybe this bike just has more power than you think, but it's being wasted.(clutch)
will do - but doubt it have major infuence on consumption
Ok that shouldnt be the issue thenI believe I have damaged diaphragm in petcock, but I can't find proper one - i think previous owner changed the fuel tap - I have diaphragm looking like square+triangle, but in every repair kits I see square shaped ones. Still - it can be part of my problem I guess, but its not completely damaged so the leak isn't big I guess and goes directly to carbs - not outside.
Yes it does. If it's not running perfectly, it'll use more fuel. You will need to apply more throttle to get to the same speeds.sync of carbs doesn't influence on consumption
vales like I said - I did clearance right, and I believe float height is right in them - I did not check the fuel level though - only float height
Depends on your model. Have a look in the manual - there's a section about it for a reason. And he is correct that the timing is set more or less in stone on these DOHC's, but if someone (a previous owner, perhaps) has been messing with it, it'll be off.My mechanic friend said that this is setted once in electric starters and there is no reason to re-do it - he is wrong?
True, but same story again. Less performance = higher fuel consumptionI must do compression - but still I think it would rather do poor engine performance than actually bigger fuel consumption :/
More thoughts?;] I will though check all of this.
Then put a jack under it, or a crate, or a log, or your mom, or something.
Idle works fine - about 1200-1300 RPM
