    CT70 K0-oil leaks around head gasket

    Doh! not sure what I was thinking. Of course, the head would need to be removed. I said my mind was always working...just not very well in this instance.

    CT70 K0-oil leaks around head gasket

    Good news, on closer inspection there does not appear to be RTV. The head bolts were loose. I torqued the head down and low and behold...no more head gasket oil leak. I got the plates and registration recently so I was able to test the bike outside the neighborhood. The bike runs like a...

    engine/frame vibration at rpm, HK0

    Not yet, due to busy traveling during the holidays. Also, that bike and most of the fleet are at my uncle's home and the flu season has done a number on their family. I have one of my bikes up in Jacksonville and all the other bikes are in Orlando, about 1 hour and 45 mins away. I have a one...

    CT70 K0 runs strong, but smokes a little- top end questions

    The air filters are newer, the snorkels have been removed on all our bikes because they always get pinched. do you think a K&N style would be a better bet and better performance? I use one on my 88.

    CT70 K0 runs strong, but smokes a little- top end questions

    Is marvelous mystery oil the same principle as the Lucas? I have used that in my 1950 pontiac (flathead straight 6) with 20W/50 as well as using it as a gas additive. It would be a shame to break into this strong running bike (although, I am curious if this is original or 1.0 over). We also...

    CT70 K0 runs strong, but smokes a little- top end questions

    This is an interesting suggestion. I was hoping for something like this to buy some time, since it runs so well. What’s the thought process of the heavier weight oil and Lucas oil? Would this interfere with the clutch? I wondered if maybe a pinched/clogged vent tube could be the culprit.

    CT70 K0-oil leaks around head gasket

    Yeah, I agree and share the same sentiment. I assumed by the red color it was RTV. I heard using RTV is usually not a good thing, but can you explain why? Should I not ride it until I replace the gasket risking catostaouphic failure? Does small amounts leaking oil from the head decrease oil...

    Yeah, we have run it for 2years and probably put 500+ We have added some oil here and there.

    CT70 K0 runs strong, but smokes a little- top end questions

    Since it was a different bike, I kept them apart as to not confuse the symptoms/diagnosis. The gold bike on this thread runs great but puffs a bit. The other thread red bike does not smoke but I found the RTV and oil around the head gasket. We have over a dozen CT70s between friends and...

    CT70 K0-oil leaks around head gasket

    My newest purchase K0, 3 speed ruby red, runs strong >40 mph with a 15/35 sprocket combo (might change to 14/35), set valves to .002, timing to .014 of the points, does not smoke. Noticed red RTV as well as a little oil around the head gasket. It has not actually dripped oil on garage floor...

    CT70 valve and points adjustment- what's your choice?

    We have CT70s, K0s and HK0s. I understand valves are .002 intake and exhaust (cold) and points are .012-.016 by the book, but I was interested in where most people have ended up setting these on their own stock bikes, or if there was any different thoughts for an 88 upgrade. I have seen a few...

    CT70 K0 runs strong, but smokes a little- top end questions

    Good Evening All, A couple years ago, my uncle and I brought back to life a gold K0 three speed after 20 years sitting in the back of a mechanic's shop. The PO put some Mystery oil in the head due to the length of time it sat. It had no spark but the engine turned over and we happily purchased...

    engine/frame vibration at rpm, HK0

    This is correct. Smooth until about mid RPM range within each of the 4 gears and gets progressively worse with increased RPM. Shift to the next gear in lower RPM, it’s smooth until about mid RPM and then progressively worse, and so on. The RPMs are the key. This is true under load, in gear, in...

    engine/frame vibration at rpm, HK0

    I tend to agree with you. Just hoping to get all angles before we drop the engine...again. I’ve tightened all bolts, removed the engine guard, removed the heat shield, changed the air box to a k&n style, new swing arm bushings, etc. the rattle is just symptom. Quieting that rattle down would not...
