@@pfgubanc It is calledThe Old Grey Windpasser test for a reason ;)

@CarloPoma-vy5ov Hi. No change to carbs at all. Seems to work good. Transmission is the same as an R100 so I doubt that's an issue. Thanks 😀

@@theoldgraywindpassertest thank you for your attention at my questions!!! enjoy your weekend

Ah 😊 I just do this for fun you know ;) So a little information for you. Yes the r45 and r65 have different heads with different valve sizes and compression ratios which is probably why the upgrade quotes different power outputs. No jetting was required. I even called them to ask. I checked the state of the plugs to get an idea of the tune but they seemed a normal colour all of the time. I guess the increased volume of air still pulls the same mix through or maybe the bigger pistons swirl it better... dunno but I'd not worry about it. Very useful lubricant Vaseline is. You ask my dentist! 😁

Oh, any other questions feel free to ask. Fitting was a cinch really. Makes the R45 usable in modern traffic.

@@theoldgraywindpassertest I'll have to look into it. I don't see any video on YT breaking it down, nor on the company's own website. Combustion chamber capacity might be the first determining factor, especially of compression ratios, however, valve & port sizes would certainly make a difference. The site doesn't even say what the difference between 65 and 45 kits are. Can you not just stick R65 heads on top of such a kit & is their "asymmetric cam", a true performance cam or is it just for the restricted models?

@@jonahwhale9047 I know you can put r65 heads on a r45 but the compression rates are different due to the squish. They recommend using the asymmetric cam too but there is such little gain I don’t think it’s worth it. Buy the kit, fit and enjoy. I really can’t worry about the finer details, life’s too short :)

@@theoldgraywindpassertest Perhaps someone else will know? The claimed torque outputs are noticeable different, 75 Nm at 4,200 rpm versus 70 Nm at 2,240 rpm, although they don't state BHP. Perhaps it's the final gearing that makes the difference if that is measured at the rear wheel? They came in different ratios for the big bikes. TBH, 70 at 2.2k is probably more useful than 75 at 4.2k ... but I'd like to see a dyno sheet. I'm guessing that top speed is governed by the final drive but, again, have no idea if there are differences there. I would have expected the R45 to have had a smaller chamber, hence higher compression, & perhaps the cam is designed to change the timing of it? Really, the first question that comes up is, is it financially worth it, e.g. to buy a R45 & turn it into an 860 versus buying an R80 or R100. The answer to that could well be yes as R45 were less desirable, & less stressed when ridden. Few people did high mileages on them.

So many people in shorts and a T. I always cringe and think, that'll hurt 😅

They are very small and have been firing blanks for years 😅 Thanks for your comments and have a fun life 😊

I'm just thinking of all the whiskey I could have bought for £680!! 😢😅

😂 Eventually

How do you know? 😀 I did go on to sell her and although she was a beauty, as it turns out, it was for the best ❤

Getting there 😀

Going to give it a try. Not too hopeful as that moss has taken a proper grip 😅

I think I'll be changing all my bolts to stainless. 😊 My bank balance is already damaged beyond repair 😅

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

I think there's about a litre of water in that exhaust 😅

Thank you. Probably cause I threatened it with the angle grinder 😅

Surprisingly yes! 😅 Plenty more to do though.

​@@theoldgraywindpassertestAin't there always?

Thank you Alender. It just a bit of fun :)

Thank you @alendervic999 I just do this for a bit of fun :)

High speed? 😂😂😂

If it makes you feel better, I've spent £600 so far and still have tyres etc etc to go.

@theoldgraywindpassertest upto know a new starter motor, all new bearings in swingarm and nushings for where the drive attaches to swingarm. And know it either needs a new tps unit or the ignition unit from front off the engine.

I'll get there.... eventually 😁

Not had one of them in years! 😉

They were spot om!

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

It needs to do 1000miles in a day for my Cancer Research challenge. So, bye bye weekends and money 💰 😀

@theoldgraywindpassertest Hope you aint planning on it happening soon, been trying to get mine sorted for a year. Can recommend Motorworks though for parts. Always get better than I take off.

​@stevebonner9108 thankfully I have over a year to get it right and a Multistrada to enjoy 😉 Your spot on about Motorworks, just bought a fuel pump from ebay and the hoses don't align.... What needs doing to yours?

@@theoldgraywindpassertest At the minute I feel everything. Was supposed to be a good bike but only done 100 miles in the year before I brought it. Gave it a full service, developed fuel leaks, lack of power - it's always been like it. Play in the rear end, all bearings replaced. New pattern injectors, second hand lamba sensor. Buggered wiring all totally corroded. Had to drill exhaust studs out and the list goes on. Thank god I've got my MT07 to use as bikes are my only mode of transport.

Swear jar? I have a swear barrel! 😁

Do they sell 300 litre bath tubs of it?? I'm thinking of buying shares in WD40 😂

Thanks Dean. I'm really looking forward to getting it on the road 😀

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

Depends on where you are 😉

It's now one of my previous bikes but I miss it... aside from the leaking oil 😁

It's really odd but I love something to tinker with 😂

Er... sorry but I laugh at the silliest of things 🤣

I think Boris would affect the handling.

I think my head would have a better grip... probably 😅

And I fancied a little project 😂 May have bitten off more then I can eat!

And I'm leading that revolution from the rear 😂

😂

Great stuff :) They don't seem to go for as much as an R100 yet there are very few R45s about. The 800cc upgrade kit is well worth the money and makes it usable day to day. Have fun fella :)

Hi there! Yes, I chopped her in when I upgraded mu Multistrada to a 1260s. I do miss the Airhead but I don't regret my decision. I've just picked up another BMW though whick I'll be fixing up ready for the 2025 Longest Day challenge 🙃 😅

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

I did. It's been about 3 months now since I did the dirty. I do miss the airhead but I don't regret it. There was so much more to do and really it needed a nut and bolt rebuild to get it how I wanted it. Have my heart set on an Airhead GS thou :o

Er... oops :)

Thank you for your constructive feedback 😊

Have fun with your build. Feel free to ask anything. Change all the oil seals, front ti back 😁

Have fun with the R45. I didn't need to change much at all with the upgrade. Not even with the carbs which surprised me. 😁

For a classic motorcycle some engine modifications are permitted so I did not change anything. Look it up on the DVLA website. (Queue inbound hate mail 😁

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. Here is the link so you can decide for yourself: assets.publishing.service.gov.uk/media/5a81f7e6ed915d74e6235144/vehicles-of-historical-interest-substantial-change-guidance.pdf

Maybe 😀

Sorry it’s a 1981 r45😊

​@richardlaker9722 I think the only thing I regret with my build was not going the full nut and bolt restore. It bit me a few times when oil started squirting out in odd places. But then again if it isn't leaking something it probably isn't working 😂 Have fun with the build. The 860cc kit is well worth it.

@@richardlaker9722 To answer your question, I'd guess that, legally, you're supposed to tell the DVLA, & especially your insurer who may ask for more from you or eveen dney insurance, but how are they ever going to know? How many loss adjusters strip an engine to measure the cc? It's still an old man's bike, not a boy racer machine. I'd say, just give them a wipe down to make them look old, or beadblast your engine to make it look equal new! I don't follow the latest developments with th DVLA though ...

Hi, it's a Puig Tour mini. And it's very good 😁

@@theoldgraywindpassertestbrilliant…..thanks very much
