Hi Everyone,

I have had this bike since i was a kid. It has been sitting in my dad's shed for about 10 years now.

I got my licence last week and want to fix it up so that I can use it to get to work.

I got it started the other day and it blew a lot of smoke for about 5min (hardly any smoke after that). It then cut out and would not idle or start without the choke outt. I flushed out the tank, pulled apart and cleaned the carby (it does not have any major marks on the internals (the "O" ring on the air mixer has a small chunk out of it). I was getting alot of fuel leaking out of the overflow pipe, but readjusted the float and it is not doing it as much now. Also have a brand new air filter that has been oiled plus put new rings on the piston.

So. It will start with the choke but then slowly cuts out. If I add throttle, it stops straight away. One out of 12 times I can get it to run and use the throttle and rev it to the top. I have seated the air screw and then turned it out 1.5 turns (as the service manual says) & played with the idle screw. None of that seems to make mutch of a difference though.

I have put alot of hours in respraying and cleaning up the bike and can't wait to get it on the road.

Awaiting your knowledgable replies.

it sounds like a possible blocked pilot jet to me, i suggest a total strip of the carb though with it sitting for so long, best option is to have all of it ultrasonic cleaned, failing that buy a carb clean aerosol and spray through all carb passageways with it...keep it away from rubberised items though

Ok. I cleaned the carb and it is idling well. But cuts out once it gets hot. I think I have an overheating problem. Once it has cooled down it seems to run fine again.

Any suggestions?

Hi Guys. Bike is runnning well now until i try and give it some gas in first gear. I can get it into second but it will only run on idle. I have let it run for a while and taken it for a soft run in first but it will not improve.

Can anyone help me on this?

Was the same with the choke out. Had a few dramas with it today. It has seemed to work itself out! Took it for a little spin and is getting better each time.

Now just have to take my front forks apart to change the oil seals. Does anyone know what size T-Handle is needed to hold onto the damper rod on the inside of the tube?

Thanks Airhead for all of your help. When I turn the allen screw, the damper rod also turns. Will just go and buy a set of T-Handles and hope for the best :spin2:

is there a drain screw at the bottom of the fork leg, on the outside of each leg? if so...get a long screw that fits and grind the end to a point then screw it in until it hits the taper spindle and 'nip it up' this may get a hold of the thing while you undo the bottom allen key :thumb:

Yes there are :idea: . That sounds like a great idea. Thanks!

Let you know how it goes.

Still trying to find a screw with the same thread.

One thing I noticed while playing around is there is oil coming out of the exhaust. If I hold my hand near the end of it and then give it a rev, it will easily cover my palm in oil. I am under the assumption that this should not happen. Would that be correct?

I am taking the forks to a local mechanic tomorrow because I want to make sure it is done right.

The bike is running alright once I get it warmed up. But when I first kick it over I have to rock the bike back and forth to keep it going. Could it be the fuel level?
