Hello
I havnt been able to start my bike in a while
I have tried alot of things
adjusting the flower nut
tuning the carb
amongst other things
today i installed a pull start
just to get the ball rolling and make it easier to asses
it makes a high pitch squeaky noise when ever i try to start it
but the engine doesnt turn
i took th engine apart and nothing is amuk

i do believe i have a clutch problem but i dont know what the issue is

also the camshaft (what the factory calls it anyway)
is wobblely
and the clutch haddle doesnt seem to have much tension

im not sure where to go from here
 
Welcome
Perhaps the pull start is not installed correctly. I say this because you came to this conclusion after you installed the pull start. Just to make sure after and if you uninstall the pull start try ridding starting it to see if you get the same result.
Since you have not ridden it in a while when you parked it I assume nothing was wrong with it so you might not have anything wrong.

hello
and thanks for the reply
and sorry just to confirm it didn't work before pull start installation either and thats why i had it parked for a while
i couldn't figure out what was happening and i would pedal pedal and it would never turn
and it makes a squeaky noise and wont turn
it seemed like when i released the handle something was loose
then i tightened the flower nut and i actually started for a few minutes (when i hit a high speed) and stalled when i lost momentum
but i cant seem to get it goin now:74:http://www.motoredbikes.com/images/smilies/weapons/74.gif
 
All I can think of is to take apart the clutch assembly and give it an exam. It seems to me there's something holding back the motor.
A combination of things could also be the answer. I'd place NGK b5hs in there also if not already that too.
Take all the drive train apart too. Usually when someone does they find the problem.
Keep us informed on it.
 
Check everything it could be a jammed chain link or something.
If you get the drive train disconnected see if the motor turns. If it don't it might be seized.
I had a seized motor before and I got it un-seized with WD40 and it ran like junk after that.

Oh one more thing if the bikes to greasy to work on take it to the car wash and power wash it.
I have to do that sometimes to my MB.

As long as you have the pull start it easy to check if you're getting spark. If so, Next thing to check is gas, Is it getting any? You can check this real easy by just dropping a little gas down the carb and giving it a pull. If it pops then find out where your gas is getting constricted. As long as the clutch turns the motor over then it's not a clutch problem, as far as getting it running anyway. See if you can get it running, Then it's easier to find other problems you might have. If the clutch is slipping too much to get it started, try adjusting it in a few turns on the flower nut. If it still slips, check to make sure you don't have a blown oil seal on the clutch side. If so there will be a fair amount of oil inside the clutch housing. This is a DRY clutch and ANY oil on it is a bad thing. I got a BRAND NEW engine once with a bad seal.
These engines are pretty basic and only a small handfull of things to go wrong. I'm sure once you find the problem it will be something simple. Also, Most people on this site recommend the B6HS but the B5 will work also.
Big Red.
 
I really think it's a clutch issue.
first, he said that the clutch lever has very little tension (a sign of the clutch or cable being way out of adjustment).
he is hearing a squeeking noise, a sign of the clutch actrually slipping.
the engine won't turn over, another sign of the clutch slipping.
he didn't mention of the rear wheel turns while trying to peddle start it or not.
if the rear wheel keeps turning when the clutch is released, the clutch is slipping.
I don't think it's an ignition or fuel problem at all.
I'd place my money on a clutch issue.

Powerwashing is a bad idea. this can cause water to get into the magneto which will give you no spark, which will only add to the problem.
if it were a jammed chain, the rear wheel would be locked up all the time.
keep it simple and don't dissassemble too muich at one time.
I'm betting that the problem is right there in plain site...which again, probably has to do with the clutch slipping in my opinion.

If it were a drivetrain (chain or sprockets) issue, the rear wheel woudl be locked up.

I don't beleive this at all about the motor once being seized and then being able to get it freed up with wd 40.
first off, wd-40 is not a penetrating/ lubricating oil.
wd-40 is a water dispersant and is not a very good lube.
if an engine is seized up, chances are that the rings have bonded themselves to the cylinder. i'm not saying that it's impossible to get a once seized engine running again, but wd-40 would not be the way to do it.
wd-40 probably would not work for this....you would need a very good penetrating oil.
If you did get the engine unsezied, of corse it would run terrible because it would not have much compression anymore.
