New Triumph rocket ....stock.... straight out the box.....plug and play ....mowpowa baby....!!!

[@bloodymarvelous4790]

I really wish people would stop saying that. Just because you would like a high performing engine, doesn't mean everyone will. If that's your argument, Harley's should come as a frame where you put everything else on it yourself. That way you buy your perfect bike without any wastage. "This should come standard." is about as useless a phrase as "Loud pipes save lives." No, it shouldn't, and no, they don't.

Cycle world, one week ago, performed a dyno on the street glide with the 131 and the stock 114. They also performed 0-60 and quarter mile. The stock 114 0-60 4.8 seconds., 131 4.0 seconds. Horsepower and torque are high rpm range. Too much money for little gain. It does get up to 100 mph faster but if there is a turn, ouch lean angle.

[@mojomanmurph1925]

The techs who did mine said I had to go with the SE Clutch and springs or I would encounter slippage. Techs have told me you need the back-pressure for the M8 performance and folks have come back to switch back to factory header pipes that have the catalytic converter because they lost performance going with straight pipes or 2-1-2 and 2-1 and is why the kit comes with the header pipe.

[@BlockheadMoto]

This is accurate info 👍🏼

[@ThePNWRiderWA]

I am not surprised. I am much more familiar with cars and boosting performance. We always did the clutch plate and springs to avoid the clutch shudder a good series.

Throw a 2 into 1 on that bad boy....not just for power, just looks and sounds good

[@jeffbarron4774]

Daytona is such an awesome dealership to visit. Always bought my bikes from Jacksonville or St Augustine but it’s still cool to see their layout.

[@z_rex46]

I hope you stick with the Sweepers Block. Everybody and their preacher who builds a Harley that’s even mildly performance oriented goes with a 2 into 1. I kinda want to see what it’s like with a 2 into 2 exhaust.

[@joesainato8051]

That’s because everyone and their preacher want to get the most out of their build. Why build a performance oriented bike and leave a bunch of full range torque and HP behind. If you read dynos and just look at peak numbers you are missing the boat especially on these big builds you can leave 15 foot pounds on the table in the sweet spot till the pipes can catch up sort of speak. Ultimately 2 into 2 or even shorter 2 into 1s will get those peak numbers it just takes longer. There’s plenty of information out there to see what goes on. On some baggers there are head pipe combos with dual exhaust that do perform very well on an M8 throughout the optimal rpm range. Hopefully that gave you a little idea of the differences

[@z_rex46]

Joe Sainato I understand the reasons why. I’ve seen dyno numbers and tests proving why 2-1 exhaust are better for performance. I just want to see what a performance build would do with a 2-2 exhaust for once. Ultimately it’s Block’s choice either way. I was just curious.

[@joesainato8051]

Zac Wade I hear ya and it looks great on his bike as well

[@JCunningham21]

the FXLRS already has the SE 37000258 clutch kit in it with 1100 springs. change the springs to the 1275n and the stock clutch is good for 160ftlb.

[@2omgwtf318]

I have a 131 stage iv fat bob, dealer didnt mention clutch plates, so i burned my clutch rolling backwards downhill on freeway lanesplitting. They then told me the stock and se plates arent that much of a difference and that it was my fault for riding too hard and abusing the clutch, even though i had asked them about the clutch because it was on harley site for the 131 kit. The stock plates didnt last more than 2 hours. I wish i would have seen this before hand. Also i upgraded to a 5.3 gallon tank and i get at best 100-110 mile range even with a dyno tune.

[@Obsidian4242]

I LOVE the sound coming out of that 2-2 exhaust, but I think it would be interesting to do a fully tuned comparison against a 2-1 exhaust to see whether it makes as much of a difference as people think. Personally, I say keep the 2-2. The thing's a beast! can't wait to see more.

[@robertlumsden942]

This is great to see. my kit should be in any day. i did order the heavy duty clutch and now that i see they slipping i am glad i did. i also went with S&S 2 into one with the race muffler. oh i did get the oil vent cap setup to. cant wait to see how yours all works out. i wish my darn kit would get in and get this done. great info man.

You should try CleanBoost MAXX in your engine and see if it makes anymore power. I think that'd be a really cool test to do.

[@modernvisionscc]

Non ethanol fuel is great but I would set the bike up with 91 ethanol fuel in your tune otherwise while traveling you could hurt the engine if it’s not tuned for 10% ethanol. Gasoline has 33% more energy output than ethanol.

I really would like the Tech to explain how with only the front cylinder being checked for A/F ratio with only one sniffer he can tune both cylinders??? Does the 131 kit NOT come with a heavy duty clutch kit?? Those heavy duty springs will be felt by your left arm. I would suggest a more progressive type clutch from a aftermarket company like... Barnett or Baker.

[@Cbollschweiler21]

This is a bad ass build, can't wait for the giggle video when its all done. For the q&a would switching to ethanol free after you've got 20k on the motor of ethanol be beneficial.

[@nicholaskominski3746]

They went chain drive because the crank run out tolerance does not work with whet a gear drive cam requires because the M8 run out terrible. .028 is I believe max accepted. Gear drive cams mostly do not allow more than .010

[@sickwideglide]

Correction: Block’s runout was at .006” measured using fuelings crankshaft runout tool with the compensator torqued to spec. The reason we didn’t go with gear drive is because Harley does not offer a gear drive setup and since this is all based on what you get for Harley’s street legal 131ci kit, we used what came in the kit.

[@wombat8882]

Thanks for posting these. You may have mentioned your current exhaust in another video (or maybe I should know by looking at it), but what are your current pipes in this video? Looking forward to following this, because I have the exact same thought process but it's hard to find info about 131 with improved tune/exhaust/cam. The advertised numbers on the Harley site are lackluster for the money. A good Stage II can come close. But I think it can be made into a monster with the type of steps you're talking about taking soon.

[@vegadealer]

My vulcan 2000 is making similar numbers on the duno, i am looking to ulgrade my clutch as well. Looking at carbon fiber with 20% stiffer springs. What friction material did you upgrade to?

At some point I actually expect people to break a bike in on the dyno and "fine tune" it immediately after the build. The idea of riding around with an improperly tuned engine is mind boggling to me.
