I stand corrected then. I thought that the Beamish was the one who changed the clutch linkage to make it an easier pull, as well as later converting the 250 to 325 not 325 to 250. I believe they also changed something on the frame, but I could be wrong on that also. Thanks. LaVern

I think I figured out my problem. I was not a paid subscriber. I am now. Maybe I can post some pictures. The first one is what it looks like today with the new fender and after the new top end. The second one with the high mounted front fender is from 5 or 6 years ago. I can't remember exactly but I did recondition a 1975 Honda TL25o, and last year I did my son's 1978Yamaha TY250. On the Yamaha I was having problems with bleed through on the gas tank son my son took it to one of his friends who does painting on bikes. On the Honda I didn't do it justice by putty knobby tires instead of trials . LaVern

How did I get in on this conversation? I don't recall commenting, but I have been known to forget at times.🙂 LaVern

One more time. This is my bike after the new top end and new front fender. I am still having a hard time getting my pictures to resize to a allowable size. I'm running Windows 11 and it's not like 10. LaVern

Let's try this again. Well I must be doing something wrong. It says max size 5.12KB. I don't think I can get it that small. I must be doing something wrong, I've resized it down to 30% of the original size , two times and the smallest one is still 72.8KB. Okay, I give up, I got to sleep on this one for a while. LaVern

Thanks. I'm trying. Here's a couple of pictures one before the top end and new front fender and one from just this afternoon. The first one was right after I did the "reconditioning", not a restore by any means, but a lot of sanding and new paint. Now to see if I can download them, guess I got to shrink them. LaVern I'll be back.

Well hello everybody. I finally did get the RL250 a new top end. And boy what a difference. I put the new piston and rings one over, and fly wheel side crankshaft seal. Apparently it has been going down hill for quite a while because the difference in power makes my 73 yrs. really evident. I'm sure you younger folks would laugh at me, but that power is going to take a while for me to get used to. I I do have s 15/60 sprocket combination, and that gives a much lower low end than stock, but I am told that for vintage, twins hock, competition it is a preferred gearing. I also remove the high mounted front fender and replaced it with a OEM copy from Suzuki/ Beamish owners Club. I haven't got a picture yet, perhaps I'll get one and post it. Thanks for reading and the help in the past. LaVern

Thanks for the reply. I too will have to wait on it. I have another project, a 1977 Yamaha TY250 I am restoring for my son, so I want to get a little further along on that, before I open another project. Mine has never been opened up so I am thinking I may need more than just a top end and new crank seals. That's what has me concerned. The closest I've come to splitting cases was back in 1970 when a '66 Husqvarna 360 I owned needed split and the guy I bought it from did it while I watched. My 72 year old memory recalls a bunch of spacers and bearings and gears. Whew, kind of scary at this point in my life. I gotta do a bit of research first. I will post on here anything regarding this when I get going on it. Take care. LaVern

djr, That does make sense. I too remember hearing the RL250 was based on the TS250, and when I looked up the parts diagram I believe there is one seal inside and the other on the outside. So it looks like there is a good chance that a case splitting is in order. Thanks for the input. Lavern

Diagnosis, I guess I won't know until I take the side cover off. I won't be doing that for a few weeks at the soonest. I tried to convert the parts list but apparently I was allowed only one conversion frompdf to jpg. Anyway, the parts list says pts 17 and 28 are crankshaft seals and it shows them on the outside. I did not have this information when I first posted the question. I do see that the picture you posted seems to show at least one of them on the inside and one on the outside. Is that what you see? LaVern

I don't know if they changed the RL250 engine that much when Beamish built them. LaVern

Let's try it again. I think the whole thing is there but it too is pretty small. LaVern

I just found a picture of the Beamish Suzuki crankcase, and it seems to show the seals on the outside. I will try to post it, and see what you think, if I am able to post it. It's a PDF. Must be too large a file. I'll see if Ican work around that. Thanks for the response. Looks like I'll need to convert it to another file type. LaVern

djr, Thanks for the reply. I am hoping you're wrong, but if you are correct, I will have to decide whether I want to tackle that or take it somewhere else. I guess I'lljust have to pull the side cover and take a peek. LaVern
