Primer says nothing about baking

Engine Enamel bake for 1 hour at 200F (93C)

Cheers. Will give that a go. Mine is so old it solidified which made me think it was plastic

Are there any workaround or suggestions to repairing/replacing the plastic/rubber grommet items as shown below. The one on the left is so damaged and old that pieces are just falling off each time a touch it.



My current thought is to get plastic pieces 3d printed and creating an new cabling run for stator, coil, oil, neutral, etc which would be routed through these printed pieces and then epoxy to seal.

All suggestions and comments welcomed here

Thanks everybody, I’ll try petrol first then move on if it doesn’t succeed. The slow/idle jet has already disintegrated in one carb, so taking it slowly from this point on. All other aspects of the carbs are in great nick, accept for the link bar, which is very corroded.
Seaman - same for me with the link bar. I have two sets of carbs with both having badly worn and corroded link bar. Not sure how I will get these sorted yet but any ideas welcome

Speaking of translation and presentation could someone please explain this to me so I know what is needed. For the clutch components No 12 is a spacer shown below.



But then how do I know what spacer I require for a 500K1 bike ?



I get the remarks with the greater and lower than the engine serials but how does one know what thickness ?

Parts cleaned and ready for assembly


Shaft through bottom half of case with spring and circlip


gear



Thrust washer and large spring






Kick starter ratchet and thrust washer then small spring




Ratchet guide plate on next and push on on to compress the spring. As you looking at the ratchet from above the arm of the ratchet guide need to point down and will lock into the case. A not tricky but will have to keep it there with one hand while doing the rest.


Finally add the washer and then attach the circlip to hold it all in.

With the new parts that arrived and over the Xmas period to escape the insanity of been cooped up I braved the cold in the  garage to get some more work done.

Mainshaft assembly

All parts cleaned and checked 


Before the first gear goes on the shaft there should be a circlip against the bearing. Note - Circlips are Honda specific which are flat one side and rounded/curved the other and shaped as show below.


Forth gear then gets pushed against the bearing flat side first.


Next the thurst washer and circlip to hold the gear in place


2nd and third mainshaft gear


mainshaft top gear


thrust washer


roller bearing and then all painted with some assembly lube


Drop the mainshaft into the top case aligning the middle gear shifter fork to sit between second and third gear. Align pin with the roller bearing and give a spin.

Thank both. Trigger what you said made sense and I checked with out the 2nd gear. Seems the gear I have been sent is the wrong part and is longer which is why the washer was not able to use the grove to rotate so the lock washer can drop in. Compared to the old damaged gear and it is noticeable.

New on the left

Been re-assembling the countershaft and when it comes to the thrust washer and the tab washer is there some special way you get these assembled ? I have put the thrust washer in first so it sits against the new replacement second gear and then the lock washer with the tabs facing the thrust washer. What I have now is a gap between the thrust and lock washer because of the lock washer tabs.

What am i doing wrong ?

Just went to go and check and yes exactly the same moving but requires effort. Also some surface rust on the bearing but will clean that up
