Does anybody know where can I get a new conrod fro my extech or can i use the new sirio motor conrod

i need a conrod to does anybody know what will work or has one they will sell

i was wondering the same thing

anybody? .....

My cooling head bit the dust (seems to be a common problem) - I got a pair of Nova P5 heads but they are too thick in the button area. I gave one to my cousin to get machined down at work, but in case that doesn't work out, is there any other affordable head options out there that are a direct fit?

i think that older GRP and Sirio cooling head would fit...

Sirio and Novarossi have the same bolt pattern, the P5 head should work. I ran a odonnell head on my old sirio motor and a friend runs one on his Werks B5 so I know they work. All sirio based heads will work. Go to Ebay and serch cooling head http://cgi.ebay.com/TEAM-ORION-21-EN...item27b2a58f03
.99 for this one with 12 hours left it will fit.

that's the problem with extech
spares are difficult to find
I already search 3 years for a rod in my extech trinity version I

What are you guys doing for run time with the extech .21. I'm running the bigboy pipe in buggy and can't seem to get 5-6 min max. Any help would be appreciated.

The big boy pipe sucks a ton of gas. The best pipe for that engine for power plus fuel is the 2013

Get the trinity phat head amain hobbies should have them

i have an old trinity extech for sale 50.00 it has a good case and p/s and pretty good condition conrod and a good crankshaft just no head or bearing

You can use a nova head as well. Its a direct fit.
