Larry's Shee Posted April 14, 2016 Report Share Posted April 14, 2016 and I tightened them as much as I could with out stripping out the holes in the cylinder. That is NOT the way to do it. Might pay to look in the manual for torque values, it's not much, like 7 lbs , tightened diagonally in stages. Might have warped the boot or cage.

As the bubbles were building like crazy, I slowly tightened each bolt to see if the leak would slow down / stop. Ill seal them up and do the test over, if it is still leaking, ill get a new intake boot. Quote Link to comment Share on other sites More sharing options...
Oldskool83 Posted April 14, 2016 Report Share Posted April 14, 2016 Per that photo I would do the following. removed reeds and check them if not replace. New reed gaskets with a light coating of gasket bond on them around the every edges. New cross over rubber intakes. If they are over 10 years old they will be dry rotted, new ones are not much. I would reinstall everything again and then go from there. Just adding sealer on the outside is not fixing the problem. I would only do that unless your gonna sell the bike. if your going to ride it farther then your yard do it right or do not waste the time at all.

I just bought another set of intake boots & reed cages from a member here and ill order a new cross over tube as well. Ill pull the boots and cages off real quick to seal them up, I wasn't going to glob it on the outside of the boot because that wont accomplish much, I know better than to do that. I appreciate the help from everyone Thanks, Grason Quote Link to comment Share on other sites More sharing options...
Grason B Posted April 14, 2016 Author Report Share Posted April 14, 2016 I stopped at Napa on my way home and picked up some of the permatex 518. I used it on both the reed cages and intake boots, after letting it set up for a while I re did the leak down test. Sure enough, it held 6psi for over 6 mins. I am really at a loss now, I was hoping to find an issue with it. For the hell of it I tossed the pipes and carbs back on it, fired it up and still running on the left cylinder only. I would tear the engine down and rebuild it, but I don't know if that will actually fix my problem. Any more ideas from you pros out there?

Grason B Posted April 15, 2016 Author Report Share Posted April 15, 2016 Yep, they appear to be in good shape. I looked them over pretty well when I had them out. The only other thing I have read that could be an unlikely, but possible issue is the crank being out of phase which would throw the timing off. How likely is that?

J-Madd Posted April 15, 2016 Report Share Posted April 15, 2016 You've ruled out most everything besides a leaky head gasket. You could have water in that cylinder. Quote Link to comment Share on other sites More sharing options...
J-Madd Posted April 15, 2016 Report Share Posted April 15, 2016 And as far as crank being out of phase that would affect the right side as the left would stay in time due to the flywheel being on that side. So it's possible. Quote Link to comment Share on other sites More sharing options...
Scrubby Posted April 15, 2016 Report Share Posted April 15, 2016 is the plug wet with fuel or dry? are you sure theres fuel going to the dead cylinder? swapped plugs left to right? Quote Link to comment Share on other sites More sharing options...
Grason B Posted April 15, 2016 Author Report Share Posted April 15, 2016 You've ruled out most everything besides a leaky head gasket. You could have water in that cylinder. I don't think its the head gasket, I have checked the coolant level in the radiator numerous times, and its still filled to the top. Quote Link to comment Share on other sites More sharing options...

The plug is wet, I have swapped both plugs & wires and it yielded the same result. Quote Link to comment Share on other sites More sharing options...
Grason B Posted April 16, 2016 Author Report Share Posted April 16, 2016 I went ahead and swapped the reed cages, spark plugs with no luck. I am really at a loss with this thing, what do you guys think my chances would be that a rebuild would fix it? Thanks, Grason Quote Link to comment Share on other sites More sharing options...

Don't take much to put out the fire. IF you do compression, leakdown, and radiator test you will eliminate those possibities. Quote Link to comment Share on other sites More sharing options...

Roger that, I'll test the cooling system to be sure. Thanks Quote Link to comment Share on other sites More sharing options...
