Making a new post to help people when searching for information.

I just put one together for my motor a few weeks ago, and thought I would share an update with some current pricing.

Mikuni HSR 42 carb – This will be a big money saver, especially if you can find one used in good condition. I picked it up in like new condition for 200 bucks on eBay with no rebuild required.

Needle valve assembly – size 2.3; Mikuni part 16030-027 - $49
Main jet – Size varies, ordered 162.5, 165, and 167.5 - $3 each
Pilot jet – size 25 is typical, also purchased 27.5 - $6 each
I got all these parts from JersRUs.com

Push button choke – Mikuni part TM29/31. You can use this push button style or the cable style. $17 on eBay

Rubber flange adapter – Mikuni part 018-42K - $22 on Amazon

Intake adapter. This is another big money saver. The three most common are the BPS Black death, Delta performance, and Performance V-Twin. There are some performance differences. I picked up the PVT “used” off MMT but never ran for 100 and no shipping. I think they are 100+ shipping from Performance V-Twins. The Delta and BPS run 300+.

Air filter adapter - $60 from the Boat Dr. Just buy this from these guys and be happy with it.

Air filter - “Free”. I have some air filters from racing karts. The diameter was slightly smaller, but was able to stretch to fit. Buying a filter is going to run you 20-50 bucks based on your choice. The Tau Ceti FA-TOR-25-BLK is the most common choice.

I think this covers it all. The necessities. Other things to consider are a governor block, rev limiter, and rain guard. The Boat Dr carries all this at good pricing. I also hear he carries a kit similar to the above, but I didn’t ask about it.

To sum it up…I spent under $475. It’s still easily do-able for under $550.

thank you for the updates. hopefully some of these shops that gouge bring the prices back down to reality. we are dealing with lawnmower engines after all.

It would be REALLY SWEET if some of the mechanically inclined individuals made youtube vids of piece explanations and install. Would help me out for sure!
