Old engine wont turn over/snapped mount bolt

[DeusIgnis]

Well, let me start at the begining.

I got my first motorised bike back in january, 49cc, got it from some dude on ebay called motowhizzer.

Anywho, its had its issue over the time that ive been running it, and it being my first and well, me starting this knowing next to nothing about engines the little guy has taken a beating, but was still running fine.

But i felt the need to upgrade and do a new build on a better bike and do it properly.

So i got a z80 (66cc) from zbox and spend 300 bucks on a good bike and it all went together beautifully. Been riding it for ~2 weeks, still using 16-1 and being gentle (in general) when i decided to open her up a bit. I hadnt tightened up anything in a few days and one of my front mounting bolts decided to shake itself loose. This then let the engine move aroudn a bit and SNAP one of my rear mounts (chain side).

Well, this annoyed me, but i knew i could fix it as it had happened on the 49cc.

So i get it home, get out the drill and easy out. Drill out the center of the bolt, break out the easy out, smack it in the hole and get onto it with the pliers but she dont want to budge. Get out the shifter onto it, still dont want to turn, and SNAP.

snapped off the go**** easy out in the bolt. and tungsten alloy aint the easiest thing to get out, so ive but that on the back burner for now, but got some ideas on how to fix it. Any from you guys would be welcome though.

So i figure, meh, ill get the old one going. All i had to do was put the exhaust back on, as the one i got with the z80 was going to require a huge amount of bending to make it fit. So whack that on, go for a ride, but she dont want to turn over. the engine hadnt been turned over for about 10 days at that point.

All that happens is the engine kinda 'pops' like gets a single spark/turn over every 3 or 4 meters. and thats it.

Ive cleaned out the carby, cleaned the sparkplug, even used the sparkplug cable off the z80 as my old one is a bit dodge. No luck though.

So, any ideas on getting my old love up and running again.

since january it has been my main mode of transport up untill about 3 weeks ago. and was still going strong when i decomissioned it, has it lost its will to live after seeing a new engine in my life?

sounds like the clutch is slipping. just today i went for a ride on one of my bikes that has not been run in about three weeks and the clutch slipped until it got warmed up. i dont know why but its fine now. give it another try, dump the clutch dont let it out slow, dont inisiate slippage.

 

[DeusIgnis]

hmmm, i only tightened up the clutch about 6 weeks ago.

ill give it a look though.

 

[DeusIgnis]

k, just tighened it up another notch.

tried coming down hill, dumping it, no luck.

the weird thing is that it wants to go, it does its little pop of the engine firing at regular intervals. could the timing be messed up or something?

for the stuck easy out
can you possible use something hard and thin so as to pry out
such as a dentist type of tool
yes - easy outs are mountain rock hard
if you can knock it or pry it out -- might work for you

I am thinking of the straight type of easy out here (square)
if it's the twist type (which I don't think are as good) may not work

you got two of those THINGS to ride -- that's cool

hey I get that problem sometimes, the engine only pops every now and again. I think the problem is due to the fuel starvation, as the engine only pops when it's getting fuel. try priming it up more or using WD-40 or starter fluid or somethin.

yeah, thats what i thought it would be first off.

so i gutted carby, checked fuel line and everything that fuel flows through and it was all fine.

going to try using the electrics from my 66 to see if that is the problem

 

[DeusIgnis]

well i tried with electrics from 66, no joy, so i came back to fuel problems so put the carby from the 66 on aswell, still no joy.

So different electrics, sparkplug, carby, and no luck. where does that leave me? magneto? or w/e its called...

 

[Heshtek]

I don't know much but if i had to guess i would say either the magneto, spark plug or CDI box?

easy way to put lack of gas out of the question

pull plug -- pour in tablespoon of gas -- plug back in -- anyTHING ?

if it fires a little -- gas problem
if not -- elect problem

I know -- it's a pretty simple THING -- but -- can cut through the chase at times

ride that THING
