Hi mate. I really enjoy your content. Look forward to every episode. Off topic here What performance pipe would you match with a 24 road glide cvo st. I take possession in november. I would really appreciate yr thoughts. Cheers
I have a common guy question. I have a 2020 RGS 114 4k and it has started making a chirping sound when hot at idle. Bike is bone stock. I’ve seen videos of other people having the same issue but no answer as to what it is. Any idea?
G'day Tommy - What's your opinion on late model M8s using oil? If Harley suggest 1 litre oil use is 'normal' for 2500Ks travelling, where is that oil going in your opinion? No other cars, bikes, or marine vessels use that much oil unless there's a serious problem. Thanks for any insights.
@paulypaulypauly8011 The early model M8s (2017 to 2019) had some Oil consumption issues that were related to 'Sumping'. This was due to the lack of oil scavenging from the 1st few generation oil pumps. The oil was showing low on the dipstick because the oil wasn't being scavenged from the crankcase properly. Some did it worse than others. This led to some folks topping up the oil & essentially over filling the bike. On the other hand there was a run of a few bikes a few years ago where ALL the piston rings were lined up from factory leading to excessive oil use. These were fixed under warranty as far as know. I personally did a out 5 or 6 bikes with this issue. Harley have to give some sort of 'normal usage' to make sure they are covering many different factors and riding conditions. I personally think that 1ltr for 2500km is a bit high but then again, I'm not the manufacturer. I'm sure they have their reasons. Most likely so they can monitor customers bikes for research & development reasons so they can rectify the issue/s. It's probably set that high so it proves that there is a problem with the bike so it can fixed under warranty / good will etc. In the case of a bike using that much oil on 2500km it would have to be either sumping or buring it as its passing the rings into the combustion chamer.
@@MasterTechMiller thanks for the swift reply. I’m referring to late model bikes (the ones with the updated oil pumps). Specifically, mine is a 2023 flhtk, and it uses oil like nothing I’ve had before. It’s only about 300 mls per 2500 ks, but that would add up to nearly a liter between services. I cannot accept that a modern 114 engine should be drinking oil like that without there being an issue. Do you think it’s possible they were lining up the rings in the 2023 bikes, or are there any other potential reasons you can think of? We went to ride to Perth from Victoria, but I’ll be fucked if I’m going to carry 3 kgs of oil for the return trip!
Hey Mate, your vids are awesome. Thank you for the content you provide us. My question is; what Cam will give good power&torque but also increase fuel economy? Just picked up a new 23 LRS and looking at a stage 2. Cheers.
Hi Mr. Miller, there’s a big discussion about lifters for the M8 all over the internet. What brands of lifters do you find out to be reliable in the long run and quieter? As always, thanks for the amazing content.
@joaomauriciobasiledesouza6204 I personally find the Screamin Eagle high capacity lifters to be absolutely fine. I do use APE High Capacity lifters aswell. I have no preference when it comes to those 2 choices. The only reason I use APE sometimes is because they are sold in the kit that I'm fitting. In very high output builds intended for high RPMs I use short travel lifters from APE.
@@hoss6048 As I’m planning on doing a stage 2 myself and the only part left to buy, I’m reading all the HDForums about lifters, and there are people complaining about them all S&S, Feuling, Wood’s etc. That’s driving me nuts. The only that seems like to be a common sense is Hylift Johnson, but I’ve just watched a video today of catastrophic failure of a Wood Night Prowler (that is essentially Hylift Johnson 2313SE) that has spread metal parts all over the engine. So, I’m just lost.
My local Harley shop dyno tuned my stage 2 with a zippers 468 cam.. I noticed a lot of 14.4 afr in that block that encompasses idle and cruising, sound right ?
Screamin Eagle now offer a Ohlins cartridge kit for the front forks. Have had great feedback so far from all the bikes I've fitted them too. The OEM clutch is fine with the upgrade 1275nm clutch springs (which you have). If you're planning on doing regular test n tune or Drag meets I'd suggest looking into an aftermarket option like Barnett.
As far a pushrods they should be checked even if the the cam manufacturer says its a stock base circle. My 131 crate motor shipped with .144" preload on the stock cam. Should be .090"-.110" preload cold. One thing i cant find is how much the M8 stretches. .100" preload hot is ideal.
Great comment mate! Unfortunately I can't find anything on how much the M8 stretches or grows. 100thou at operating temps is enough to allow for cold starts in cold conditions eith thick oil & on the other end it allows enough of a margin for hot running conditions. When I do high output applications, I almost always use short travel lifters from. APE.
I have 2022 RKS 114. I saw your discussion about louvered baffles and how good they are for performance. I had perforated cheap slip ons. Then I had the 447 SE cam and lifters and cam bearing put in and the bike was way loud for early mornings in the neighborhood so I got the 4.5 Tab Bam’s with the 1.75 quiet baffles. Really great down low but sooooo crazy quiet. My question is since both sides are different in diameter what do you think about putting the 2 1/2 inch louvered baffle in the right side and leaving the left side with the 1.75 with regards to performance?Any downside? Thank you for all your incredibly informative content.
I don't think there would be any downside to it at all. I'd imagine it would help with top end HP as the smaller baffle on the left side helps to create scavenging in the main collector & right pipe.
@@MasterTechMiller thank you so much for responding! I love that you said that because I was thinking the same too but I was just guessing. Can’t wait to try it. Have great day
Hi Tommy I have an sns 475 in a 21 lowrider s 114, super street 2-1, IAM looking to change the cam, to a more torque cam, as low rpm rideability is poor with this cam, cam you recommend a nice smooth cam at low rpm, I was thinking after an Andrews M462 or M465b not sure what the Cr480 would be like
I'll do a quick video on it for you over the weekend. I'd always stick with the SE cam plate & oil pump over the other aftermarket options & I will cover why in the video. It will be a very similar style video to this one but I'll be in the workshop.
@@MasterTechMiller Massively appreciate that and thank you!. I just can't find good info online comparing them, but I'm glad to hear you prefer the SE kit. Thanks!
Hey my opinion probably won’t matter to you but I can also say the SE cam plate and pump is the way too go. SE cam plate and pump have always been one of there best products screamin eagle have made even in twin cams
Hey tommy i got a 114 lowrider s was thinking a cr485 cam kit but dont think i need 130hp 130 torq would u recommend a cr480 with just stock injectors and manifold would that be fine for more torq
@MasterTechMiller cheers man im just gunna stick with slip ons and change air filter to.was gunna chase big numbers but I think the cr480 with what I got should be enough 115hp 130tq be heaps of fun haha
Bored of this cam kit 😂 I wouldn’t say bored more like use to 😅 I am considering stepping up to stage 4 at some point Even though I love my setup now YOUR always wanting more I have a Redline 472 fitted and the tuner not Harley Davidson Dealer upgraded them because it needed them to get the best out of the bike and I am wrapped with it BUT after 10months of riding I WANT MORE 😂
How about you do a video on tuning basics with power Vision? Plenty of people out here don't have access to and don't have the finances to pay for dyno tuning.
@@danr919 You don't say!...You can't get a dyno tune if you don't have a tuner near you and once a tune is done you are stuck with it and can't alter anything without having another tune done. And we can't all afford to run off to a dyno. You should probably read my first post again.
Ok mate fair enough I was just replying to your comment saying some people don’t have the finances for a Dyno tune so I was replying that a Dyno cost as much as a power vision that’s all. So I did read your comment. All good mate relax have a beer don’t take it personal, we are all here with the same interest to help one another 🙂
@geraldgoodiii6993 The Screamin Eagle Perfect fit pushrods are VERY strong! Stronger than the Screamin Eagle adjustable pushrods, however there are some trade offs. For example, when building a very high performance high rpm engine with large lift & duration on the cam you'll want a very strong pushrod, so you'll probably want a SE Pefect fit set. Keeping in mind that most engines of that nature have had cylinders that are decked down to achieve 0 deck height & then the heads have normally been faced down to reduce chamber volume & increase comp ratio which then brings the perfect fit pushrods closer to being too long & not correctly loading the lifter. They are definitely not junk & I like use in the old twin cam stage kits that come with them. The SE Adjustable ones are a great compromise.
@@MasterTechMilleri wonder if the SE ones are in my bike. FYI parts were ordered for my bike .. I’m the dude who had the 482 cam. Doing SS flywheel and changing to 480MT cam And 64mm intake etc and that SE oil pump the OEM one not keeping up on that crankcase pressure on the scavenging side .. 124 turning higher rpms bc of that 482 cam .. blow by like mad but NO oil burn up even after a 5k mile trip ripping the fuck outta it and it was hot af out. Thank u Ultracool lol I’ll let ya know how it turns out I’m tired of the horsepower cam too much work lol
Hey mate! You may have to do it on a computer rather than phone? I'm not totally sure. When I see it on a laptop it has a button to click that says 'Join' beside the subscribe button.
We need to clone Tommy and send him around the globe. The dimwits in Idaho wouldn't know an M8 from lawnmower engine. Wouldn't trust 'em even if they say they could do a cam swap.
Thanks for the support mate! I'd love to come to America one day & do a working holiday & travel the States in the process, working on & building engines for customers
