what engine for r60v2

[harrysvr]

I`ll buy the r60v2, can you advice me what engine+muffler to buy.
Ι`m thinking of the os .70sz-h what`s your opinion?

The OS 61 SX, OS 70, YS 61 ST2 are all good choices.
I prefer the Hatori brand of mufflers. The quality and performance of the Hatori's is great.

I have a OS 61 and it runs well but I have "heard" that the OS 70 is kind of a pain to tune correctly. After seeing the way my YS 80 runs. I would put a YS 61 STII in mine (if I were to have to get a new motor for some reason). My 2 cents. :smokin:

The 70's make good power the are a little needlely but with a regulator (kline) or similar you can tune them right in. I have one now but it has rich and lean spots. James at OMI said the regulator will fix this problem.

I'm getting ready to order a Webra 75 AAR Duel pluged head for a stratus with the new three needle carb and Webra regulator. On 10% nitro. will keep everyone posted.
