MC28 needle buttons

Fri May 20, 2022 7:33 am » Post: #2 » Download Post

If you are talking about MC28 needle button you have a few options.
1. Very carefull modify the stock ones.
2. Buy this pair on Jauce - link below, but wasn't clear if springs included. Can find springs at good hardware store.
3. Have a set printed in nylon using an online service from file I made a few years ago. I had some made and they work fine, may need a little mod to fit spring you will need to buy. There are many online sites who do plastic printing, but gotta be nylon or other plastic impervious to fuel. I'm actually surprised T2 Racing in Japan hasn't started selling these.

PM me with an email address and I can email you cad file if you want to print some. I actually think I have 2 at home in Texas, but I am in Europe till mid June. Shipping parts to you from US however small will be costly even if I give you the buttons. It will be cheaper to have them printed locally.

Thanks for the detailed reply. Looks like the springs aren't included. The problem for me is that if I go to a hardware store to buy springs I wouldn't know what to look for. I've PM'd you my email address. any ideas what a good starting point would be when I start the jetting?

Please don't discuss jetting in the public forums. It causes (has caused me) too much grief.

The English version of the MC28 HRC Manual (with recommended base settings) is available in the Members Content section.
