When that rod gets spinning and heated up, it can stretch pretty far. Lol. One good hit to that piston and the bearings now ready to explode. Just one good hit is all it takes. I caught one engine before it went. Was just tapping the head at high rpms. Took her apart and it had slightly bent the piston pin and the bearing was riding really tight. Was ready to go, but I caught it right away when I noticed the power loss.

Thanks @Street Ryderz for all the good info, my measuring setup wasnt the best, i checked it 3-4 times just to be sure, but i could be off a little bit. Yeah I keep looking at mountain80's cylinder head & his chamber design looks a little bigger than that/ different design. His cylinder head is made by the same company. I was reading on another website & they were saying that each different head shape from CDH was a different cc amount, polygonal was 5.5cc, square was 6cc & the round head was 6.5-7cc.

I was thinking after my reply that it could have been a 5.5cc to start with, so that makes sense.

Fair enough, always good to kick around info with others as experience and results always speak for itself, well keep the squishband looser on the minarelli build

Yeah I wanna build a minnie bad! Maybe some day.

 

[mountain80]

Thanks for the info, appreciate it.

Np. Sorry I made a mistake, with plug in my cdh head it was 7cc not 6 as previously stated.

That's a good head. 5.5 cc
I run that head on one of my minarellis. Works really good at keeping keeping it cool even after milling of a couple of fins to get the temperature probe to fit.

Thank you sir, I've been running that head for couple days now, & it takes alot longer time to get heat built up in engine. It does a great job at cooling like you say.

 

[mountain80]

Yes I agree Even though i did a milling on mine their a hella lot cooling area and bulk.

Mountain80 did you mill yours also for cylinder head temp gauge?

This is the temp guage/tach/ hour meter I use. It says out of stock but search runleader and you'll find a different vendor.
