Hi, Anonymous the vast majority of service, parts fiche, and owners manuals on the internet are "FREE" to download and all service manuals contain wiring diagrams in the back pages. The rest usually charge a modest fee of $15 and there is a handful of obscure, rare, obsolete, and very old models that are no longer or never were available and some were never printed in English. The Indian and Philippine markets are usually in E-book format only, for these rare occasions I shall look on eBay and find the cheapest one available. Most of the manuals will cover your exact make, model, and year otherwise one will be provided that comes as close as possible to your bike and will have most of the same info that an exact manual would have. If there is no $ sign after the manual link it is free to download.

It may still have some water in the tank/system or the spark plug is no good.With a full tank of fuel,add 200ml of methilated spirits.It breaks up any moisture and lets it burn away.Also,with the motor out of gear,run the bike at higher revs and close the choke fully on and give full throttle at the same time.When the motor starts to die,flick the choke off.This can sometimes unclog a carby jet that may be slightly blocked because with the air choked,it gives a sudden **** off fuel.This may/maynot fix the bike but it the 1st thing to try before paying a dealer and it can't hurt anything.Hope this helps you

I know unless they changed the design the clutches need oil to operate properly to allow Slippage when clutch is in (handle is pulled in) Are you trying to shift by rocking the bike? It should shift with the clutch engaged (Engine not running) just by rocking the bike back and forth and operating the shifter. I do know without oil on the clutches with the engine running there will be to much force put on the gears to allow them to shift plus it is a very bad Idea to ever run an engine without oil in it. Be it a 4 Stroke or a 2 stroke.

May be dirt blocking a jet .Take carb off and give it, and all jets, a good clean out, and treat it to a new plug too....

2003 Honda CRF... | Answered on Aug 31, 2011


the inlet needle in your carb. may be worn or the float is not level that is if there is no dirt in the carb. or gum deposit go at a honda dealer buy a can of carb cleaner honda brand is the best let your parts soak a hour or two oh by the way a inlet needle cost about 30 dollars have fun

2003 Honda CRF... | Answered on Aug 14, 2011


You sound like you have a blocked idle jet in the carb. Honda trail bikes love new oil, clean air cleaners and clean fuel. After a while a build up of tannins and crusty residue will invade the carby bowl and usually migrate through the carb via the jets and the emulsion tube where the jet needle runs. The easiest way to fix your problem is to remove the carb and go through it. Clean all jets and check float height and generally get it back to scratch. You will have to re- adjust your idle and mixture settings after you have fited it back to the bike. If you are not Mechanicaly savi then I would suggest you take the bike in to your local honda dealer and get them to go through the carb for you.. It's not a big problem and is easlily fixed.

Hope this helps...

Cheers...
