Russ - you live "just around the corner" from Phil Hacker (of the UK FJOC) - if all else fails and no one here can't give the answers, spend £20, join the club and talk it over with Phil - he's the UK guru on FJ's.s

Hi John, Here's a picture a of mine - you'll have to take the top fairing off the get to it - it's mounted to the frame.

The best example of anti-motorcycling Government action ever. Make it so difficult, expensive and time consuming to get to a DECENT bike that riders will give up and just move onto driving cars (or into Uber's)

Not sure if it's still the same, but when our youngest passed his test at 17 (6 years ago), he was limited to 33bhp for 2 years (in his case until he was 19). So, we bought him a 2003 Fazer 600 and had an "official" set of 33bhp resistor plates fitted to the carbs (fitted by a friend who runs a vehicle repair business and who "stamped" the documents for our insurer).. once the 2 years we're up, I simply took out the restrictors (washers in the carb inlets) and the bike was back to its full quoted power (95bhp, I think, if you can believe Yamaha). All around, I thought that was a sensible approach. He too rode a Rieju RS 50 Matrix Pro as a 16'er, but we destricted it (as soon as we got it !!) and for the 4 weeks from his birthday to passing his test, he just rode the Rieju - saved the cost (and loss on re-sale) of buying a 125 for the short term (it helped that his mum was a bike instructor, so he was able to get everything in place to Ben ready for his test as soon as he was 17).

Yeah, not much in the way of hills in this area. We often travel up to the Peak District and up around Ladybower for nice Saturday rides ?

I'm no expert and I'm not sure what any specific differences there might be (other than emissions related stuff - carbs, exhaust ignition module etc) but I think that the 4BR was the European model designation (XJ600S/N Diversion) and the 4DU was used for USA models (marketed as the Seca II). So I'm guessing your newer engine came out of an American bike imported here. Maybe there were some valve or cam differences, but tbh, I doubt it. Double checking on eBay seems to confirm that items from the USA, or listed as Seca II parts seem to have the the 4DU model number and those from Europe (priced in £ or €) or listed as Diversion parts generally have the 4BR model number. this table below was taken from some info in German XJ600S Diversion XJ600N Model Year 1991–2003 1993–2003 Veh Type 4BR(A)/4BR(B)/4LX/RJ01 4BR(A/B)/4LX/RJ01 Design Type Half Faired Naked Bike The link here should take you to the USA owners manual for the Seca II - which only lists the 4DU reference https://dd5394a0b8ca8e97ba29-abf76f3d91a2125517d6c7c409f095c7.ssl.cf1.rackcdn.com/content/common/manuals/1994/seca_2_1994_LIT-11626-08-87_1813.pdf

Are you two (Cynic/Airhead) near to Daventry? i don't run, but bicycle (mountain bike, I'm not a road-bike type of cyclist) a lot around there - helps me keep the weight off and stay fitter than the average old man ?

Charles Watts, in Rugby (check them out on t'internet), are usually very helpful in supplying lengths of pipe/bar/angle etc (their off-cuts are free, they just have a voluntary Charity collection box at the till for donations). They also carry out small works (for a reasonable price usually) such as cutting, bending, machining etc on metals they supply. I found them very helpful when making up brackets and spacers for my FJ 12.

Ha ha - well that fitted in this thread perfectly, it gave me a laugh ? - seeing someone else has the same problems as I do ??

Duh, I think I'm thick Cynic, I thought "Olivers Army" was about young/poor people being used as the cannon-fodder in modern armed forces. I'm obviously missing something ??

I've decided to self identify as a "F" in the "LGBTQi+" alphabet....... not a "Mother F", just a "F". i hope you all treat me fairly as such - if anything any of you say, or post, offends my personal sense of worth, then you will be punished and must correct your statements to something I believe represents the view of me that I want the world to believe is true/accurate (irrespective of what I'm really like) - it's my right !!

That is not funny !!!! its offensive to those members of our population who don't have balls !!! Take down that post immediately and report yourself to the Gender Fairness Police immediately for arrest and punishment.

Welcome in 11's Nice to hear you're doing something with the XS's - and it sounds like not going to wrap the exhausts in that silly cloth ?. Cheers.

It's a bloody good job I'm not middle aged then.......Omil (old men in Lycra) doesn't have the same ring to it ?

I know this might be treated with the utmost disdain ?, but why not try wearing a pair of padded cycling shorts instead of normal underpants. We always wear our (Lycra style, not baggies) cycling shorts, under our bike gear, when out on the off-road bikes. Single cylinder bikes with thin, narrow seats, can be a literal pain-in-the-arse, but wearing a pair of my cycling shorts, with the gel pad, from Aldi, made off-roading a whole lot more comfortable - might help with the numb-bum problem and it's a pretty cheap solution to check out (Decathlon have reasonably priced ones as well).

Sorry Gary - I don't know the specific answer to this - by I'm sure you could get help from the VJMC (Vintage Japanese Motorcycle Club). Reckon tll be one the most frequently asked questions they get.

It's been a while since Bikerchick posted on here - does anyone know if she ever got the issue resolved? i had similar problems years ago with my CB 650 Honda (an in-line 4 cylinder bike for those too young to remember) with regard to blurred vision and headaches caused by vibration - the problem disappeared when I put a handlebar fairing on the bike. I didn't put it on to solve the problem, but after fitting it, the problem disappeared. When I took the fairing off before I sold the bike and rode it for a while, the problem immediately came back - then it disappeared again when I swapped by old AGV helmet for a new Arai. i think the vibes and headaches were caused more by the specific combination of my height, helmet and airflow, than by vibes from the engine. Change any of the factors, the riders height, helmet shape, or airflow profile and the condition disappeared.

Quite possibly - but from what I understood, they won't issue an age related plate without a dating certificate from a recognised source. can anyone confirm the actual position ?

Welcome in Mark. Hope you enjoy your time here and find it useful and enjoyable. Cheers.

Hi Mark, i think that the DVLA have probably given you the info you need. I would think that if the numbers are already linked to a Reg number, it will pop up when they go through the process to give a registration number for the bike you have. If it's not been registered before and if you don't have the necessary dating certificate/information, then you'll probably end up with a Q Reg plate. You probably won't lose out either way, unless your plan is to restore the bike and sell it for a profit - but the issue with that, is that even in pristine condition, a YB 100 won't be worth much, so a profit on selling is unlikely any way. if you really just want to restore it and ride it, go ahead, get the MOT and take a chance on the DVLA. One more old Yamaha back on the roads would be reward enough for me ?

That's a shame ! Hope you're on the mend now ?

Hey Drewpy - did you get an photo's from this ?

Welcome aboard Tim - I've no MT03 knowledge or experience, but always like to hear about what others have come across ?

Hi John, Welcome to the forum - from the look of it, you like XV 1100's ?

Welcome in ? - just a couple of requests, please don't put exhaust wrap on it with knobbly tyres and call it a Cafe Racer, or take off bits and let it rust then call it a Brat Bike !!! Unfortunately, more than a few decent XS's have been ruined like that. Flat Track replica, proper cafe racer or just standard would do just fine for me ???
