Grade 8.8 steel or just above. Grade 5 Titanium Ti-6Al-4V Phil

So I got the Ti fasteners for the rear drive finished. New torque arm bolt made and nut fitted along with new Titanium spacers. The new spacers allowed me to make them the precise width required. Previously I had a .5mm shim in there as well as the std spacers were a fraction thin. Now for some Ti fill and drain plugs. I've learned the secret to drilling Ti is super slow speeds. I turn all the Ti stuff at 460rpm but that's too fast for drilling. Around 290rpm or even slower for larger drilled holes seems to help the drills survive and back it out every 3 or 4 seconds to let it cool for a few seconds and never let off the pressure. it's either cutting pressure or zero pressure. Anything less than a positive cutting force and the material work hardens instantly and cooks the drill. If anyone else has some tips I'd be keen to hear them. Phil

Loctite red. Epoxy in this instance is for knuckle draggers. Phil

Loose valve guides aren't going to cause bent valves. K-lining them is a way better option than replacement. Phil

This guys stuff is really good and his videos have backed my life long decision to never fly in anything other than large commercial jets with big companies. It's no guarantee of course but some of the things on this channel are rather disturbing and very sad. It also backs my other decision when a young man in the aviation industry to not take up private flying. I always thought I'd be able to attain an unrestricted pilots licence but I'd never thought I'd have the time and money to attain "expert" status and then do enough hours to maintain the skills. I've always considered piloting to be a very serious business. I think I chose right and went with motorcycles.

Yes but some ways end up looking bodgy and the mufflers cocked at funny angles from the rear and to much outward rotation at the front. I'd be interested to see some images side, front and rear of Titanium high mount mufflers and secondaries mounted to std length passenger pegs. Phil

Another great Aussie band. Great song and a lead singer with a brilliant "rock chick" voice. Check out the live versions as well.

Don't bother getting into a discussion it's pointless. Once someone is on a bandwagon and gets feeling all warm and fuzzy with the other climate warriors involved in this now 2 trillion dollar " climate emergency" industry there's no changing their ideas. You just need to wait it out or the next big panic comes along. Like "peak oil" the "ozone hole" the "70's oil panic" the "Y2K bug" Eventually another train pulls out of the "panic station" and they all jump on that. The next generation won't be worrying about the climate they'll be too busy scrapping old wind turbines, solar panels and Lithium batteries and getting a headache figuring how to do that without wrecking the planets ecology. Phil

If they are high mount then the std pax pegs wont work. Phil

I agree. His main excuse though is the KTM isn't exactly the winningest bike and has only been anywhere near one in the last season and a half. Up until the 2023 season they were pretty ordinary to bad. Binder on a Ducati might be another story. Phil

Why do teams continue with Vinales. In the last 5 seasons he's had all of 3 wins! The ultimate "soggy Cornflakes" man. Can't get a MotoGp bike off the line in a race to save his life. Why do teams fall for these guys trading on yesterdays performances. He's never even won a MotoGp title for goodness sake. Ten MotoGp wins total since 2015 with best championship result 3rd twice the last with Yamaha 5 years ago. There's a list of stars aligning a mile long for this guy to even podium and yet they keep hiring him. Amazing. Phil

I have had 5 different muffler combo's on my bike as a 2 valver and 2 different cross overs and the bike ran well/exactly the same on all of them. Below is the "delta" map of a 2000 V11 Sport main fuel map compared to the factory "Titanium" main map. So you know the expensive new ECU they supply with the Titanium mufflers same as Ducati used to do with the approved Termi exhausts. Note there is zero difference in the fuel map. Ducati used to do a similar thing, sell you an $1800ecu with Termi mufflers and just add 3% fuel everywhere which wasn't necessary. My 1198 has a Full Ti Akropovic exhaust and what do Akra say to do when you fit their system? Nothing. Fit it and ride it which I have done and it's fine. You want to get the absolute maximum out of a set of mufflers or exhaust combo on pretty much any bike then you'll need to map it but for 99% of bikes 99% of the time it isn't necessary in my experience. You might need to tweak the Co and the air bleeds a little but other than that install and ride.

No "correct tune" required. Just bolt them on and ride it on the stock factory map. Phil

Well not strictly true. One advantage of Diesel engines is they have no throttle body and therefore no throttle blades. The engine speed and ability to produce torque is controlled by varying the volume of fuel only. A piston aircraft engine with a variable pitch prop the power is controlled by adjusting the throttle to a specific manifold pressure and the engine rpm is controlled with the pitch lever. It's a bit like a helicopter driven by a gas turbine. In that case the engine turns 100% rpm all the time and when you pull up on the collective pitch it coarsens the blade angle of attack which provides the lift and this requires more power so it schedules more fuel to maintain the RPM at that load. RPM stays the same. Turbopro aircraft much the same. An NA petrol engine will produce a manifold vacuum at idle and part throttle, more vacuum at high rpm on the overrun with a closes throttle and a little less than atmospheric at WOT. Before takeoff in a piston engine a/c the pilot will do a 30inch check at the threshold run up bay to ensure he is making full power before the actual takeoff. @Chuck needs to chime in he's the expert in this area.

Yes same. Phil

I don't really need nav on the bikes but I often wondered if this would work. I spent a 42 year career in aviation and cared for my hearing immaculately after seeing a lot of the old guys I started working with deaf as posts. Always wore ear plugs on the bike and never went to loud music concerts or such things. Didn't stop me from getting Tinnitus though

It's a question without a definitive answer. What throttle position? what altitude? what rpm? what load? Throttle at idle? throttle closed and engine at 3000rpm? Phil

Some detailed images of the actual issue might have been nice. Images of speedo drives with blobs of JB on them don't tell us much I'm a images person I don't read very well. Phil

He's better than a nerd. He's also a commercial pilot with a captains rating for a major US airline, owns two performance car tuning and accessory companies and has written a few books on automotive turbocharging. He knows his stuff. Phil

Gasoline. Yes the Germans had the burden of high octane fuel in insufficient quantities and quality. They also used aromatics to boost the octane that had a higher vapour point and resulted in sever fuel dilution which destroyed engine bearings. Big issue for them for a while. They were also short of Nickle for exhaust valves which led to them developing chrome plated exhaust valves. They were fighting with one hand tied behind their backs in engineering terms thankfully for us. It took the allies over a year to figure out the Nitrous oxide injection the German were using. They found the systems fitted in crashed German aircraft but they couldn't figure out the gas they were using. A lot of the German piston engine tech was lost after the war when the gas turbine took over and designers are now starting to use what they developed in WW2 in modern engine design such as Direct gasoline injection. Yes I've seen just about all of Gregs video's and he's very good although my Spitfire wing knowledge comes from another source Gregs backs up my readings on the subject. His car stuff is good as well. The English post war had a knack of burying the brilliance of the "non English" and exaggerating their own peoples contribution. The winners write the history as it were. Phil

From my personal images Daytona pits 1988.

Did you know the iconic Spitfire elliptical wing was actually a German design? Phil
