I’ve acquired a spare pair of 14H carbs, and ordered new insulators from 4 into 1, new floats are also on the way. Gasket and o-ring kit as well.
The carbs have been cleaned (in an ultrasonic unit) - and other than leaking floats they are apparently ready to roll.
I’m running K&N pods at the moment off the installed carbs and plan to implement a version of this solution documented by Mike;
When I purchased the bike it was equipped with crappy foam filters and as a result was running very rich. It was responsive and would wind out all the way with no issues, but it ate spark plugs (they would go black very quickly). At this point, with the K&N pods installed I’ve determined the rich condition has disappeared somewhat (I haven’t had opportunity to test fully with new plugs - that’s a spring time project), but I want to move the pods back so I can install the side covers.
I’ll be going through the new carbs and making sure all the gaskets and o-rings are new and then doing the same maintenance for the old units. I’m wondering if this main jet solution will provide enough variety to get the mixture settled and leaned out a bit.
Carburetor jet kit
Kit includes
2 x # 135Main Jets
2 x # 140Main Jets
2 x #145 Main Jets
2 x #150 Main Jets
2 x #155 Main Jets
2 x #160 Main Jets
I do want to be careful - the temp here runs into mid to high 90’s F in the summer (although cooler air is close by - I’m surrounded by mountain passes).
When all is said and done I’ll have two sets of 14H carbs to play with. Leaving one set stock and re-jetting the other is an option. I don't plan to change any parts but the mains, unless I run into obvious issues with old OEM brass.
I've been reading old posts and there's a large variety of ideas out there. I know there are a lot of variables here, but any suggestions on jetting and words of encouragement or warning appreciated.
