400 piston
« on: April 09, 2013, 02:31:58 pm »
Hi , i'm after a 77.25 maico piston for a 1974 mod 400. Any idea's it's the 2nd oversize in a Mahle.

Mahles for the 400 are not as easy to get as they used to be. I grabbed one off USA eBay a year ago for $60, a bargain for a NOS piston and ring and they still occasionally come up for under $150. If you haven't already, give Les at VMX Unlimited a ring, he may be able to help.  [email protected]  02 4981 7241
 Here's a Wossner, it's what I mostly use these days. Les has 'em in stock aT A cheaper price than from the USA.http://www.ebay.com/itm/Maico-400-Wossner-Piston-Kit-NEW-/170601719627?pt=Motorcycles_Parts_Accessories&hash=item27b8a7a74b&vxp=mtr#ht_1847wt_892

Had a quick hunt through my spares and alas, I have a second hand 77mm sorry. I replaced this, with I think, a wiseco that was for a Yamaha? It has the same gudgeon height as the Mahle but I did have to machine the skirt to clear the crank webs! I got the Wiseco through Stackers.
Hope this helps.

It was probably a Suzuki RM370 piston....I've never actually done the conversion but it seems popular in the USA. I'll have a dig through my 2nd hand piston stash tomorrow and see if I've got something.

Thanks guy's for your input, they put Maico pistons in 400 Suzuki's  so why not the other way.
