I have a question to fellow owner of this engine...

I just finished breaking my engine in, and checked the head clearance, it was 88mm, yes that is correct.... out of the box... My question on 25% nitro
should I set it in the 50mm to 60mm ranage?

I thought these motors came from the fatory setup to run on 16% nitro.

Let me know what you guys are seeing...

Your not joking... I was very supprised also....

So what is the correct head clearance I should be running at?

To get down to 53mm, I only need a single 10mm shim... Something just does not seem correct...

I have never checked the clearence on mines, but will do as soon as I re-assemble it. (Took it down to check it over)

I have been using 25% on mines and to be honest, I am not totally impressed with the performance. I have been testing different pipes and found a combination pipe / header that seems to perform the best but it's still not mind blowing.

I should say that on taking down the engine I noticed 2 shims, whereas my 5P came with one.

Once I double check the clearence I may remove a shim. Are you saying that 50-60mm is safe for 25%?

per a post on here, but I'm not sure of the link:

2. Based on head clearance, choose your nitro %:
16% Nitro .36mm - .40mm
20% Nitro .40mm - .50mm
25% Nitro .50mm - .60mm
30% Nitro .60mm - .65mm

As far as the performance, I have agree results... Even better with proper Clutch setup and the OS 1040 pipe.

Thanks for the info.

What other pipes have you tested?

Also, you used solder wire to check the head clearence?

Can you post any further details on this?

Perhaps a photo or page link?
