The Mikuni HSR42 is a great carburetor. I had one on my Low Rider and it never skipped a beat. I think some dealer finger trouble occurred to the enrichener circuit on this one – although that circuit should never have been touched at any time during my reman engine install back in December of 2005.

I’ve been looking – unsuccessfully, so far – for a couple of non-standard parts for the carb. There’s a piston and a spring involved, which I’ve been trying to find locally. No such luck. Unfortunately, dealers only carry jets/needles and re-build kits.

On March 5 I finally broke down and called Mikuni in Northridge. I was patched over to the voice mail of someone named Steve. I left a brief explanation, including the two part numbers that I was unable to obtain locally, followed by a request for a callback.

No response so far.

Had I been able to find an email address for Mikuni, I’d have sent them an email.

Today I emailed asking them the same question, and in a matter of an hour I had a reply directing me to a Canadian distributor for the parts that I required.

I’ve ordered everything I need, plus a little extra. Thank you, Sudco.
