BMW R45 R65 R80 and R100 Airhead Power Upgrade from Seibenrock

[@garyinkin4834]

This bloke makes watching paint dry exciting!

[@theoldgraywindpassertest]

Gary, it took me days to get this fun 😂 Thanks for your wonderful comments 😀

[@trailingarm63]

I thought you said you were going to be speaking about it in great detail? You managed to get through the entire video without any detail whatsoever! Enjoyed the film though, glad you're happy and the condition of the R45 is a credit to you.

[@theoldgraywindpassertest]

Ah. Guess your right but not a vast lot of detail to go over as the units just unbolt and replace. The NJB Shocks really seem to hit the spot but important to get the right spring for your weight. Thanks for watching 😀

[@asbjrnhagennielsen6560]

Thanks for your recommendation. I did it too, to my R45 -and what a JOY it is now. Easy to handle, and lots of power -even from 1500rpm. Great (45 year old) bike now.

[@theoldgraywindpassertest]

Glad you like the upgrade 😊 It's a great little run around.

[@hansmonitio7462]

These old airheads are indeed still fun to ride. I have a 79 R100RS and each time I ride it, it still amazes me how good it performs. Bought it two years ago, won’t ever sell it. My wife will probably divorce me I do.

[@theoldgraywindpassertest]

I know what you mean. I don't need 200hp to have fun. The misus prefers this to my Multistrada :)

[@thibaultdubaret9863]

Did you change anything in the carbs after this upgrade?

[@20111111jorg]

On Power, I had an R65 for about 3 years. I ran with others who mostly had R100's but didn't lag behind much as it got up to 110 mph (indicated) very quickly the few times there was a straight road and no police. After that it was a series of R100RS's which I took to top speed a few times but mostly only used the power to pass. I noticed it stumbled right around 100 mph. On having to do a top end I asked to put in dual plugs and a few other mods but nothing which would hurt the engine's reliability. With that I could get it up to 125 very smoothly from it's stumbling to 120 beforehand. Now I have an F800 which is a wonderful performer but seldom bring it above 80 and have never taken it to full speed. None the less it's always satisfying to know your machine is running at it's peak.

[@theoldgraywindpassertest]

Sounds fantastic! The R45 before the upgrade was definitely lacking. The The 800cc kit it certainly behaves just like and moden bike.

[@ekspatriat]

Surely to make the best of it you would also need bigger carbs, a matching head with bigger valves. Without that I'm sure it will be stifled.

[@theoldgraywindpassertest]

Actually no. The kit is matched to the heads so if you change them you get a different squish rate. I didn't change the carbs or even the jets and it seemed to fuel quite well. I thought it would run lean but that wasn't the case. However, you could be quite right but I haven't tried it. They do recommend that the cam is changed but to be honest, the kit made a huge difference anyway so I didn't feel it was necessary 😊😊

[@jochenwagner5170]

I’ve done it too Last winter. This Bike (R45 with the kit) from now on is my obsession. Especially: it reminds me extremely to my 750 Norton Commando, leaving a village, 5th gear- inhalating the throttle needles higher….

Did a similar upgrade on my wife's R65 about 30 years ago. But one thing led to another, ended up changing out the final drive, heads, carbs etc. I wish I could have found a wrecked R100 or R90 and used th parts from that. Could have saved me a lot of money.

[@theoldgraywindpassertest]

The good thing about this kit is that it's designed to run using the same carbs and heads. I have now swapped the diff though 😀

[@yuillguy]

I bet the bike goes absolutely fantastic and I agree that the short wheelbase bikes are a pleasure to ride. I regretted selling my R65 to a friend so bought a 78 R45 which I converted using pistons and barrels from a R65. Just returned from a 800 mile tour of Devon and Cornwall, fully loaded and it never missed a beat. I also have a R80/7 so didn’t really need to upgrade to an 860cc, oh and I’m a bit too tight to shell out the cash needed. 👍

[@theoldgraywindpassertest]

First of all I must say what a fantastic Austin 7 you have. Wow! A neighbour of mine has a 1929 Flat nose Morris and a 1929 Swift and I spent ages helping him restore it. I also was going the R65 Barrel and Piston route but I couldn't find them at a reasonable price. I have just completed the 500mile service and after resetting the valves it's running sweet as a nut. I love it to bits :) Suspension service next and then I may just swap the diff or get a higher ratio 5th as there is a, "Lands End to John o Groats in 24hours", run I want to do. Let me know if you want to join in :D

Hi Paul. Always trying to have a little bit of fun 😁 Glad to see you 🙂

[@stephensaunders4668]

You may be interested in a story that illustrates the interchangeability of BMW parts. Many years ago prior to the whole GS craze that started with the R80GS a guy called a Lindsay Urqhart who was the Australian BMW manager built a bike and sidecar racing ace built a trail bike GS largely styled after the BMW ISDT bikes. It looked fabulous but the interesting point was, he used an R100 engine but with an R65 crank and shortened cylinder barrels. This gave about 800cc with a bore and stroke combination not seen on any BMW at the time. I read a review of the machine which was mainly positive. The bike had Maico twin shock suspension and really did look great. Sadly it’s current whereabouts are unknown. Many manufacturers don’t reinvent the wheel with every model. Design engineers use many design solutions across many models and years. Take a look at 70s to 90s gear selector ratchets which were largely the same across both road, trail and mx bikes. Harley Davidson does the same which allowed me to use front brake and suspension parts from bikes as late as 2010 on my 1978 machines, turning old bikes into well braked and safer pieces of equipment. Never sell a BMW is my advice as every time I get back on after a long lay off I am reminded of BMWs slogan from the 70s that read, ‘Sheer riding pleasure’. I have three and love them all.

[@theoldgraywindpassertest]

That's a really interesting story. I'm thinking they must have modified the barrels a little as there wouldn't be enough compression otherwise. The setup must be very similar to what I have now with a 60 kit. I'll be looking that story up. Thank you 😊

[@stephensaunders4668]

I have a photo of the bike in a scrapbook somewhere in storage but Peter Thoeming aka ‘the Bear’, at times editor and contributor of various Australian motorcycle magazines was aware of the machine and as he told me, once passed on purchase of that machine at an auction. Yes I am sure that the barrel height must have been shortened. At the time I wondered what this must have done to the relation of the pushrod tube alignment. Probably would have to taken height from the head end.

Hi, thanks for the uploading, very hekpful to learn about this kit, just a couple of curiosity questions; do you modify carburator and valves as well? is the kit supplied with new valves? Is new cylinders generated torque compromising the transmission ? thank you !!

[@theoldgraywindpassertest]

[@stephenfuters6833]

Wonder what that increases power to ….60-70bhp maybe?

[@theoldgraywindpassertest]

The quote is 45bhp with 75 torque. What it equates to is a very usable bike that can do an easy 80 or 90 if you can hang on. Needs a r100 diff I think 🤔 as it revs a little high. About 5k at 70mph.

[@rondridealmeria]

Nice one. What about the carbs? do they need rejetting? ot just swap piston gasket and cylinder

[@theoldgraywindpassertest]

Hi. Surprisingly I haven't done a thing with the carbs. I thought I would need to rejet too but carberation seems to be spot on. I've done about 600 miles so far but after 1st run in service, plugs plus looks fine and in fact it runs very sweet.

Hi there , i want to do the Same on my r45 (BY 11/1981) Most tell me that i MUST use the 32 bing carburators (r80 for example), instead of the Original 26 bings. Please let us know if and what you rejettet. Greetings from Germany, Daniel

[@theoldgraywindpassertest]

@@leinadj.7948 Hi Daniel. I thought exactly the same but I am using the original carbs with no changes at all. I've pulled the plus several times but they seem the correct colour maybe even a little rich and as it really is running very smoothly I have just left as it is. I'm not sure if mine are 26mm but they are the flat top Bings that came with the bike. I'll try and find out for you. I was also thinking that if you pull twice as much air through the carbs it would certainly need re-jetting but apparently not :) If I had not of fitted the kit I would probably have sold the bike by now because as standard it really is no faster than a 125. So my advice is, fit and enjoy the bike. You will get stopped most places by people asking about it which is sort of nice :D Regards, David

Hi. I didn't get the camshaft. As the bike runs so much better and even smoother I don't think it is high in my upgrade list. I wanted enough power to safely overtake and keep us with my friends. What I have got is a whole lot more. My next upgrades with be sorting out the suspension and possibly a r100 diff as there is now so much more power I'd like to reduce the revs at 70mph by at least 500rpm. Safe riding 😀 David

This is the bit I looked at taken from the DVLA website The following are considered acceptable (not substantial) changes if they fall into these specific categories: • changes that are made to preserve a vehicle, which in all cases must be when original type parts are no longer reasonably available; • changes of a type, that can be demonstrated to have been made when vehicles of the type were in production or in general use (within ten years of the end of production); • in respect of axles and running gear changes made to improve efficiency, safety or environmental performance; • in respect of vehicles that have been commercial vehicles, changes which can be demonstrated were being made when they were used commercially.

Entertaining video, many thanks! As a returning biker I considered getting an R Ninety T but really don’t need the full capability it offers. Your R45 looks great and I was wondering if it may be too small for someone 6’ 1” ish?

[@theoldgraywindpassertest]

Hi Endo, I tried the R9T too and it's a great bike but I felt that the R45 had something different that a modern bike can't offer which was why I spent the extra to make it into a 860cc and that made it very usable. I am only 5'6 but the man who I bought my R45 off was in fact my ex-boss for 7 years and he used it regally for years. He is 6'2. The R45 and R65 do have a shorter swing arm and seat than the R80 and R100 but exactly the same frame and most of the engine. IMHO I think the R45 is too underpowered to be anything but a short hopper. Lovely but frustrating at the same time. I'd look for a R65 or R80 unless you feel happy about fitting an upgrade kit... and better brakes :)

I bought one ready converted and really like riding it - it feels like you're going faster than you actually are! One change I made is to fit an r65 final drive and speedo because like you I found it too revvy on the open road - it's 12% higher and fourth gear is now equivalent to my old fifth. Can I ask you if you find that if you open the throttle in say 4th gear at around 2800rpm it vibrates till 3000rpm and then pulls hard? I don't know if I am bogging it down and this is normal or if it is a tuning issue

[@theoldgraywindpassertest]

Hi Paul. That's exactly what I was thinking of doing and glad to hear it worked. May I ask what final drive ratio you fitted? I too have a vibration at somewhere in the range, I think it's about 4k then goes but I'll get back to you on that. I thought it may be mechanical which it may very well be if we have the same symptoms but if mine is different I think it could just be carb balance. Glad you like it.

@@theoldgraywindpassertest So I have a 31/9 final drive fitted to answer your question .

That's why I got the 860cc upgrade kit. Almost unridable without. 😀

[@lesleysmith5623]

As an engineer, I regard your misleading video title as ‘clickbait’. Nothing about the upgrade, just you rambling about motorbiking.

[@theoldgraywindpassertest]

Thanks Lesley. I thought I had clearly mentioned the 860cc upgrade kit I have fitted. I'm just a bloke having fun with some spanners, oil and a bit of wind. 😉 If only I was female and hot, I'd be keenly making money out of this but instead all I get is a little fun. I hope you have fun too. David x

...and very badly at that

What a plonker

[@jonathan-th2bg]

Great video.

R45 was a complete dog of a bike

[@theoldgraywindpassertest]

Cheers! :D I happen to like mine though ;) Probably wouldn't without the power upgrade kit tho.

I used to really like my old R45 for short hops. I also ran a Laverda Mirage 1200 at the same time, and that provided the thrills , when I needed them. Nothing wrong with the R45.

[@francescosalvioli8073]

and when they drive it is always a crap experience🤣🤣🤣🤣🤣🤣🤣 amazing!!!!

[@theoldgraywindpassertest]

Depends on where you are 😉

[@evanleebodies]

Just get an R65LS saves all the hassle

[@asbjrnhagennielsen6560]

But there is a big difference in 650ccm and 860ccm. ;-)
