WILL RUN WITHOUT #4

[steptoe]

down the track we'll have look see

[Jonesy :-)]

I should have said what did you find with #4 carby?

[steptoe]

it was mate, haven't looked at the 36's yet,,
spent time perfecting what I'd learnt and putting into mine {and every other set now} what I'd learnt and straight up , instant evenly hot pipes

[Jonesy :-)]

Knew you'd sort it eventually, what was it with #4?

[steptoe]

good news, sorted, ended up being carbs
    took some time to rebuild the original 81 carbs,
 with the problem  progressively getting worse over time and having learnt so much about worn carbs of late and nutting out how to fix them, I applied all that to my set
the bike hasn,t sounded like this for a good many yrs,


bloody carbs, if they're not right they can cause some grief

Has been put on hold until the Generals motor gets reassembled. There's already 2 motors torn down in the workshop and we're running out of room on the benches.

Any Updates/scenarios/setting on fire....... trinkets or tidbits of information?

Hi Doug. No mate. It's just an ordinary small valve XS11 head.

I have been thinking about it a bit and coming up with bugger all...except, Does it have the YICS head on the bike? That can be a game changer in tuning for sure. I have a YICS tool I use when tuning an 81 as we had YICS here then. I usually just leave them in once I am done tuning the carbs and buy a new one. This is just a wild arse guess and a question as to when the YICS system was in place there.

sorry buddy, but it,s actually in the bolt that holds the oil filter bowl on,
the ball and spring with the holes is the prv

I was browsing through the manual and recall seeing a PRV valve....pressure relief valve...its actually on the oil pump...not up at the breather...sorry mislead. Thx for the correction.

[steptoe]

Jeff we don,t have a pcv valve,, oil/crank splitter,, the lid that holds the crank case airbox hose,
the test was cold, and at the end of day,

[AussiXS11G]

umm errr..... whats a PCV valve?

[excess.11]

Another check would be on the air fiter box that the tubes in there are all ok from where the crankcase breather hose connects into.

[excess.11]

To state the obvious....you would want to see less leakage when the engine is hot because of better sealing due to expansion....as a cross check...do both a compression test as well as a leak down test both hot and cold.
