40,000 Mile 2020 Suzuki GSX-R600 - M4 Exhaust & Dyno Tune!!

Great vid. Have a vulcan 650 decat link pipe and can. Was backfiring due to header air leaks. New studs with longer worms sorted the problem. Love the 650 twin lump. It a high reving engine so can cruise at 80 no problem.

Good power and 41k miles, good motor 👍🏻

41k miles is really nothing for modern Japanese bikes. There is a myth about sport bikes that says they are shot out after 50-60k miles but that is only on severely abused bikes with minimal maintenance. I know Honda designs their sport bikes to maintain factory compression up to 200k kilometers (125k miles). Meaning power would start to be lost at that point but the motor would still be fine for another 60-70k miles before oil burning would push retirement.

Miles like age is just a number, a reference point. It’s what you do within those numbers that matter. You take care of your bike/ car it’ll take care of you. On the other side you see people that baby their high performance machines or garage queens that experience more issues then those like this young lady that utilize it. Respect to this young lady out there getting it in. Good work E and crew.

Sounds like she would have done better just buying the whole M4 shorty. Great video...

Isn’t it better to be on the looser side of the spec for valves? They will only get tighter. IMO I like to be a little looser.

Have to be in spec per manual? No? If it's loose you would hear the ticking sound?

I'm at 50k kms odo and due for valves and I'm SURE there out of spec couse the engine is loud in idle you can here that annoying ticking sound but it isn't that bad power is still strong I might be wrong if you can explain.

Yea please more content, you're really good not only at your job but how you speak and explain things. I think you can be better than Moore "mafia" 😂 imo

Just did a valve adjustment on my Honda with 45,000 valves were perfect spec .
