Failed emissions test on 2004 Honda CRF150
Hi this is not a permenant fix but before you take it for a emission test you wana make sure the engine is red hot ,clean oil,clean fuel these are the only things that could cause problems with a carbon test im not over familiar wiv the 150 but i assume there is no computer as these can sometimes make sensors tell lies if so then i would suggest looking at this aswell.Hope i have been of some help
I have a knock when
Have no idea what the bike is except its a HONDA so hard to give accurate answers! in most newer bike the cam chains would be auto tensioned so depending on what your bike is possibly could tighten it manually but unlikely
if the bike is old ?? then the cam chain can become over stretched and still slap about no matter how it is tensioned
also likely knock cause would be piston slap which occurs when the piston and cylinder gets bit old in the tooth
I would need to know age of the bike but more importantly what model of the bike as us mechanics at least need to know if has 1 cylinder or 4 cylinders to help you guys
Where is the air fuel
its the flat head screw that is actually inset in the carburetor, and it should be a brass screw
How do you time the
The drive chain for the rear wheel does not get timed. The chain for the Over Head Cam ( OHC ),
also does not get timed. In both cases the position of the chain doesn't matter. What I think you are asking is how do you time the OHC? There will be a mark, or marks, on the cam gear(s). The gear (attached to the OHC ), is what gets timed. Put the piston on TDC then refer to the diagram below.
How do i adjust my carb for my honda crf 70 its either
To know if it is too rich or too lean or if its ok , you will have to remove the spark plug i.e. after a short run.
If the spark plug is blackish sooty thn its rich, if its totally whitish thn its lean, if is brownish, its ok.
To adjust this you will need to set the air-mixture screw. Tighten it all the way in slowly taking care not to overt tighten it as you may damage the tip of the screw, thn unscrew it 2 &h alf to 3 turns outwards, start your bike's engine and monitor, you may thn go either way alittle to suit the idling.
Best would be to replace the saprk plug.
Hope this helps!
