Shearers vs CPI

[locogato11283]

I'm not saying they fucked up, but Snipers need fuel.

Could be, We spent 3 days testing different stuff on my motor and getting it dialed in so we didnt mess with more jetting variables even though the afr was coming in alright. Maybe this season we can test more.

Thinking about picked up an extra set of pipes this winter to mess around with..

I have had shearers before in the past and Im looking into get some CPIs.

How do these pipes compare to shearers as far as power delivery, when it hits etc.

Little less rpm then Shearers, but a bit more grunt early on. Kind of a happy medium between your SLP and Shearers.

421 Driveline cylinders. This was done at driveline with lane and bill

Need timing and compression? Throw fuel at it and give it a bit of both.

[Ayesully810]

We ran plus 5 timing for all 3. Both shearers and snipers could have used +6 for sure. We were at 170 or 175 psi one of those 2 on 110

Were these oof Snipers or inframe?

[Ayesully810]

Inframes sir

I would say your blowdown is too low and possibly your time/area on ex port.

[RagunCajun]

The cylinders are NOT ported correct? If true, why not just ride the bike as is and discuss with whoever will port the juggs which pipe is better for your goal once ported. Then get those pipes. You may or may not like the pipes until you are ported but you'll have them ready. It also gives you time to maybe pick up a set used for a better deal although I prefer new.

 

I discussed sniper, shearer and Cpi with my builder. Turns out shearer was best for what I do.

Turns out shearer was best for what I do.

That's what everyone thinks, until they see the graph of Snipers overlaid with Shearers.

[RagunCajun]

That's what I kept reading before I laid down the cash. I read and searched every thread I could find. I trust the supporting vendor who ported my juggs. I may experiment later in time with a set.

Not to steal a thread. Making changes to my Redline ported 10 mill "trail"  bike. What pipe. I have sb Shearer now. Thought about BB or snipers. 

[RagunCajun]

Call redline and fine out. I just talked to him earlier about me going to snipers. Im staying with shearers. Booyah.
