Nice intro Bob, you're as old as you feel , and if you can still get your leg over the seat you don't need a hip replacement!

Try these .... https://pyramid-parts.com/products/black-fork-gaiters-for-yamaha-dt175-78-86 via Google.co.uk or Wemoto do a selection of gaitors , just have to measure your old ones for the nearest fit? https://www.wemoto.com/parts/search?q=Fork+Gaiters+Black&partsfilter=pattern

Welcome bud. Good interest in some big ones there, bit out of my league though! The forums a lot quieter these days, however, don't let that put you off, they're several regular visitors with similar interests in the bigger bikes. Nonetheless, we all share a common interest regardless of engine size. good luck with your search.

Anyone know what's happened to the regulars that used to post here? Blackhat250, Jimmy, Airhead, Cynic, Mike1949, Their names used to pop up quite regularly ....Seems a long time ago since Wild Foamy, Elvis and Dirty DT posted. Are they all ok? does anyone know, hopefully still around?

Very nice Dig, you did very well. Well Done mate.

Hi Dig, Looks like you're making some progress, I note there is an index mark (raised dimple) on the middle tooth of the selector cog in the recent top photo. Yamaha uses several of these dimples and indents on parts inside the gearbox, my 175 has several parts with them, when you put it back together, you align the marks etc or they are aligned when the box is in Neutral. Is there a corresponding mark on the other cog it interfaces with? or does it relate to the roller shifter head( the bit with the spider)i.e that bent over tab for example on the exposed spider.

On one of our sister sites, someone is describing the same part, although I've not joined to see the photos etc... https://yamaha-enduros.com/index.php/forum/general-discussion/6495-74-dt250-shifting-issues They are describing the pawl and Blackhat250 was involved. is that the same Blackhat250 member who was a regular here? Maybe he can help if he sees this post? Trouble is, according to his profile, he last visited back in August 2022. Hope he's ok?

Hi Dig...I've had a look around the net, found a DT400 Manual which has a picture of the same part...we're not allowed to post links to manuals. Unfortunately it doesn't explain why the cogs are lined up like that, as in, for example put the gear in neutral then attach the cog to be similar. Have you got a haynes manual? might be worth it. I'd imagine its probably something simple which is causing the issue.

There's another topic which can be locked up. 10 years later...might be a record?

That post from Vira above is a copy and paste of part of my earlier post in this thread, taken from my 4th posting it is word for word including punctuation which suggests this is a BOT post and is not wanted here.

Welcome fella.

Hi Clive, Keith is what we call a One Hit Wonder! He only made one post (the number 1 above his current bikes indicates the number of posts he made) This was some three years ago ....never to be seen again.! He may well have a valid reason for never posting again, but there are plenty of One Hit Wonders who we never see again. Nonetheless , you rounded off this topic, so i think this topic can be closed off and locked to further posts. You get a thanks from me for taking the time to write.

Hi there, yes if you run LED headlights the AC lighting coil won't light them up. But in theory that doesn't stop you running everything (all LEDs) off the battery and simple charge the battery from the charging coil. Back in 2011 I wrote a detailed write up about converting my DTMX from 6v to 12v long before it was available in kit form. You might find it of some interest. Give you some idea of what's involved. However, as Mark points out, worthwhile speaking to RexSpeed for sure. It's in the Workshop section.

Well done Albert, we should sticky this as it often comes up.

Are we the only two about these days?

Better get your arse out there then Snake!

Happy New Year to you all, here's hoping 23 is somewhat better than 22. !! As I continue to renovate our house my bikes sit in the garage drained and under covers but otherwise neglected! hopefully this year all my efforts will complete my project and i can get out and about again on my bikes...here's to 23. Cheers

Welcome mate, and a Happy Christmas to you. Nice lot of old bikes there, I've got the 175MX and my 400/4 (as listed on the left there) Hope you enjoy your time here, it's a lot quieter here these days with little being added so do make use of the search facility at the top to find older posts. All the best, and a Happy new Year to come.

Merry Christmas to you ALL too. Quiet day down here on the South Coast, took a walk along the beach after dinner and only saw a handful of people.!

You're welcome Stuart However, I'm slightly intrigued by your name!....have you more than one bike? Your name is RS100 Dave....not RS200 Stuart?

Have a gander at this Stuart, you may have already seen it. A bit on the RS200 https://www.pressreader.com/uk/classic-motorcycle-mechanics/20201016/282965337583467

You're welcome stuart, I've got a couple of eye loupes one is 20x and 16x and I think the other x2, but I must confess I've no idea where the 20x one is!!!, I've just looked and its not where I thought it was! None of them are big, hopefully I won't have a buy a magnifying glass to find it Although I have both my BIkes on Microfiche, I also bought the parts books when I found them, so the microfiche is just of historical interest and forms part of small collection of literature I've collected over the years on my bikes. I've also given you a few thanks and now you've got a Gold place on the Leaderboard!

Just been browsing the net for the past hour or so for you. indeed 3L2 is the RS200 dating from 1980, can't find an online parts catalogue for it or pdf parts manual.( takes someone who has a copy and interest to have uploaded it in the past and still be sitting on a server somewhere!! ) Looked on ebay of course, including the 'sold and completed' items and didn't find anything either. Occasionally a microfiche becomes available (i've bought some in the past) these were often the only source of information for all products as it was a very popular format back in the 70's 80's. You don't need the official microfiche station to view them, I remember having one at work, but you can read them with an eye loupe and bright background light. Sometimes you have to get these sort of things if you run an older vehicle. So if a microfiche becomes available it might be worth buying one. The picture of the 3NA gasket shows a compressible cone gasket, these fit into a cup like structure on the silencer or just inside, and the castlelated lock nut compresses the gasket around the downpipe. If the downpipe and silencer are similar size then the gasket might be a ring one, Often a soft asbestos like ring which fits down inside the silencer onto an inside lip, the downpipe slides in and is pushed into the soft material making a gastight fit. I've seen bikes in the past that used this arrangement. An acceptable alternative (and may be a solution for you) is exhaust paste: smeared onto the lip inside the silencer and the downpipe pushed into it. The exhaust heat cures it and it goes rock hard. Seals the joint but it can be difficult to remove. Having said that, sometimes it's not as good as it sounds and always cracks up and starts blowing again and you end up repeating the process on a weekly basis!!!....which is why they invented exhaust joint tape!! and you'd wrap this unsightly silver bandage/tape around the joint, it would cure with the heat, go rock hard, enough to get it through the MOT and then fail a few days later!! But by far the best solution, would be to use the proper gasket, like I said earlier, you may end up using something for another model or indeed another make of bike. It's all down to knowing what it looks like and how big it is. The part number will really help you.

What sizes did you get when you meaured the downpipe and silencer Stuart? Ive looked up this part number 3NA-14714-01 and its OD 1 1/2" ID 1 1/4" 5/16" wide. (39mm x 31mm x 8mm wide and found that it supersedes the following part numbers : 132-14714-00, 132-14714-01, 3NA-14714-00, 3T5-14714-00, 4YYE-4714-00 and fits many bikes but the RS200 is not listed amongst them. ....but if the size is right?? 1963 YG1 1966 YG1T 1966 YG1TK 1966 YL1 1967 YL1E 1967 YL2 1967 YL2C 1968 YCS1 1968 YCS1C 1968 YLCM 1971 CS3B 1971 CS3C 1973 RD60 1974 RD200A 1974 RD60A 1975 RD200B 1975 RD60B E 1976 LB802AC 1976 LB80IIHC 1976 RD125C 1976 RD200C 1977 LB802AD 1977 LB80_3D 1978 LB50PE 1978 LB802AE 1979 LB50PF 1980 LB50PG 1975 RS100B 1976 RS100C 1975 RD125B

Stuart, most 70's and 80's bikes had sleeve gaskets that fit over the downpipe and they are not very thick, and the silencer then fits over the whole lot, clamped into position. I'd venture to say that theres a good chance they used the same gasket for many of these similar bikes. It wouldn't surprise me if you said the RD200 gasket and RS200 are the same , and it wouldn't come as surprise to learn it was the 3NA-14714-01 !! if you click on that link above/below .https://www.ebay.com/p/1737220622?iid=372598027432 clicking on the picture gives a nice exploded view. For the price bud, I'd buy one anyway just to see if it fits!
