I’m supposed to do a track day in September with a friend of mine, but his R6, which has a 2009 engine built by a shop up in Oregon, now has a rod-knocking noise. “Bang”, loss of power.

Is there a reputable shop in the greater Bay Area that you would recommend to inspect/diagnose/tear down/rebuild an engine that was built by a different shop?

In classic internet form I will not answer your question but will add...

Preferable options, in order...

1) get it back to the original shop under warranty, with pressure if needed

2) find a good used takeout engine and put it in

3) buy a used (crashed?) bike, take the engine out and sell off the rest or keep for spares

4-6) ?

7) pay through the nose to have someone else fix a broken engine and pay for a rebuild 2x
 
Yeah, I know - absolutely not ideal. The original builder is in Oregon and took forever to do the initial work. That, coupled with this result, has him wanting to look elsewhere.

I believe that #4-6 is “collect underpants”.

Was there actual machining done to the engine? Do you know what was involved in the original rebuild? was it a teardown, replace worn parts and reassemble or was it more involved?

Fair questions, but what I know is in the first post - that’s all I’ve got. I can ask, though.

He sent me the invoice. It doesn’t show what the ship did to the engine, just a “remove and replace” (swap?) with a “rebuilt [shop_name] engine”/“fresh built by [shop_name]” engine that is supposed to make 130 bhp, plus velocity stacks, full exhaust and dyno tuning. No mention of cranks, rods, cylinder work or anything else remotely specific.

He said:
“I think it ended up leaking coolant and overheating the engine. I can’t see anything visible but a friend said he could smell coolant leaking.”
 
The Internet seems to think a 2009 R6 made 129 HP off the factory floor

If you're just going for a track day to have fun an engine swap is probably the most expedient and economic path

Probably. Got a rec for a shop to do the work? :teeth

I have no idea of his reasoning behind purchasing that engine. It was before we were friends. Doesn’t much matter why, though, because it’s now kaput!
 
If you were in the San Jose area the shops I know of are Santa Clara cycle accessories, Evolution Motorcycles and RMC moto. Nichols in milpitas might do it but they're mostly Ducati. Just about anyone can unplug a motor from a Japanese bike and plug in another though. Tuning it I don't know

Lovely, thanks!
 
I know of a good mechanic in the Sac area and got recommendations (from BARF) for an engine builder, who is also in Sac.

Looking at eBay - running engines in good shape are around $3500.

Didn’t see any r6 engines at gold river.


If it was me, I’d probably have a mechanic inspect it and give his opinion. If it needs to be torn apart, I’d pull it out and find a good used one locally so I could inspect it.
 

Engine builder?

I have an 07, Suzuki gsxr 750. Picked up an exhaust from a guy who is parting out his bike. I’ve been accumulating extra parts for it - wheels, gas tank, foot pegs, tail, ecu….. Mentioned he’s posting up the engine for sale so told him “I’ll take it.” Any reputable engine builders? This is...

this situation is the perfect example of why you always need n+1 bikes

disagree
this is why you need a duplicate of your track bike, as either a complete runner or a parts donor which is n+1 in a sense but not the generally used sense
 
Sorry to hear about the dead engine. That's always a bummer. If you're near the East Bay area, Jim from Catalyst Reaction does this kind of work. He's located in the Brentwood Antioch area. I believe he also does bike pickup and drop off for a fee if you can't get it to him. Here's the site: https://www.crstuning.com/who-we-are/
The address on the site is their old shop.

Thanks! Jim worked on the suspension on my Triumph, but I didn’t know that he does engine work, too. I’ll point my friend in his direction.

I did a track day and my gsxr 750 threw a code. He was very helpful in diagnosing the issue and offering suggestions on how to fix it.
