These bikes do have a bit of a reputation for the CDI units going bad.
If the cdi unit is going bad, is it possible that there is still a spark but its sparking at the wrong time??

I don't know. I have had what I believe, the timing advance quit working. I say I believe because I never actually checked it but by the way the bike was running--no power, not wanting to rev, exhaust sounding "flat"-- I came to that conclusion. Tried a different CDI unit and the bike woke right up.

Another thing I have had happen is the plating flaking and peeling off of the cylinder bore. When that happens you loose power, burn oil, the compression gets lower or completely goes away, depending on how bad it is coming off and the bike gets hard, if not impossible to start.

I bring this up because in one of your previous posts you say when kicking the bike over you noticed it doesn't get difficult to kick every 3rd time anymore like it used to. This sounds to me like you have lost compression.
I would run a compression check if I were you. Disconnect the auto-decompressor cable that runs from the kickstarter area to the rocker cover before you take the reading.

Wink dripping sweat from kickin to death 85 tt600

I didn't notice this until last night but the right side of my carb (the vacuum) side the plunged needle assembly was stuck halfway open, which very well could cause a hissing noise at idle and then shut down because there is to much air. Also my compression seemed to tighten up a little after I closed that needle with a pair of needle nose. It still won't kick over though. Today I will bump start it and manually close that valve at idle if it doesn't do it on its own and see if it still hisses. I will run comp test today I have to go buy a tester. I will let you guys know what happens. YDIS Grrrr this thing was recently rebuilt too...


Okay the saga continues, couldn't even bump start it this time....wtf

Try taking out the spark plug, and giving it a kick. Check your decom cable is correct Get that carb working right. Good luck!! Got fresh gas in the tank.

GULP................30psi..... I hate my life sometimes, the only thing the easter bunny left me was a rotten egg of a bike. Would 30 psi cause my bike not to start(haha) is it wishful thinking that my carb being open can cause low comp? There is resistance in my kick but I suppose that's just the crankshaft, and what maybe left of some rings......

Don't get discouraged. These are fun bikes, and when you get the kinks ironed out, I think you'll enjoy it. But for right now, it sounds like you'll be doing a top end rebuild. Before you start tearing it down, check and make sure your valve clearances are okay and haven't tightened up on you. Also, when you get into it, put a socket and ratchet on the flywheel bolt and try to move the crank up and down, to see if there's any play in the crank main bearings. I'm gonna have to pull my TT600 engine back apart after doing a top end rebuild because I didn't check mine before hand and didn't notice they were bad until I had it back together. Total stooge moment on my part.

It's probably apples and oranges, but my '84 TT600 has '90 XR600 fork legs and front wheel. Kelly.

Hey, I have a question. Where can I get a longer shift lever? I can't wear my MX boots with the stock unit. I have to rotate the lever up a LONG way to fit my size 13 boot under it. With the lever rotated like that, you basically have to push it backward instead of up to upshift. That's an exaggeration, but you get the idea. Anyone? Thanks, Kelly.

Kelly, You can take the shift lever to a welder, add a 1 inch and you can shift like a 12 size shoe!! Just have him cut in the middle. ED

I'm not 100% sure, but I seem to recall the TT having 43mm legs, and the XT 41mm.
