Hi, im looking for PSR set for this engine but no luck so far. Just wondering if the PSR set for the R2101 is compatible with this engine. Thanks.

What should the head clearance be on a XZ-R speed? I got a new piston and liner but I bought the version 2 which is different according to a previous post. I want to make sure I get the head gap right so if anyone knows the required clearance (using solder) that would be very helpful.

Thanks!

Hello crew ...

one question ... im starting on 1/8 onroad

I need some feedback on OS .21 XZ-R V2 (OSMG2042) ... its on my budget and it seems that, not being the last and top model right now, would be a good contender on track. My other alternative if i dont get this OS model, will be Novarossi ISON 7 ports Onroad .21

Thanks a lot for your feedback,

well u quoted a post were the guy asked about an xzr .21 so im assuming the statement you made had to be on the .21 u didn't say other wise.

yes,it is OS speed. they broke the rod often compare to other brand,even with engine's temp below 100 c. here is high humidity and air temp between 32-36c,any idea?

here in ny in the summer we have same conditions high heat and high humidity and we don't have any problems. after how many gallons do u change the rod? we change it every 5 gallons. also what fuel do u run? most guys here run byrons, I use kosmic.

Don't know that fuel but 3% oil is not alot at all. We have not had any trouble with ours we don't even change the first rod till 5 gallons.
