kawasaki kh125 bike problem

Hi my name is gilly and my son has recently purchased a 1994 kawasaki kh125 k7 motorbike? It starts ok but when hes riding it if he goes more than 40 mph the bike loses power and cuts out! It always starts again

 but is really frustrating. It has engine compression and weve changed the spark plu, weve also reser the air/fuel mix too. Has anyone got any ideas as to what the problem could be please?

Kawasaki KH125 bike problem.

A worn carburetor, perhaps (needle and jet)?
How many miles has it done?

Kawasaki KH 125 K7 1994

Hi Gilly55 and welcome to the site:smile

Sounds like a fuel starvation problem,not really surprised with a 20 year old bike(and a two stroke as well)With this engine being a disc valve type not piston port,and the carb being under a cover on the side of the crankcase,the carb will always look new,even on a bike of this age.I think the fuel tank,fuel tank tap filters,fuel line for kinks or crushing,and carb float bowl would all need inspecting before moving on to anything else that could cause this problem in a 20 year old two stroke.Saying all that,although the bike is 20 years old i would have thought if just recently purchased it would have had some guarantee or very limited warranty(i would put a 30 day warranty on it myself?)so if it has? take it back to the shop,i am sure they would take a look at it for you for no or little charge?Good Luck

KCMC:tongue:

kh125 two stroke

hi gilly, two strokes need the exhaust/silencer cleaned every few thousand miles, as they block with carbon, this is usually a dirty job, regard s andy
