No photo's yet mrb505. But just wondering is a 1985 Honda RTL250s a rare bike? And if so would it be criminal to fit the forks and wheels out of one into my Bultaco? Just wondering of course. Not like I would do that. But just got the tubes back today from the Hard chromers. I'll put them together in the next week or so and I'll send some photo's.

My Mother rides a TLR and my sister rides a TY175. Enough said. Sorry guy's. Good one scot taco . Look what you have made me say. Cheers brt650

Just an update ; I've fitted Honda brake shoes to the rear. That's fixed that end. I've fitted Honda shoes on the front , almost. I'd rather not go any further than that, otherwise I might loose some Bultaco friends.

Where do you actually live scot taco? So I can send around the flogging crew. Ha ha Bultaco all the way buddy Cheers brt650

Hello shercosi, Can't go past PJ1 for good paint. See if you can get this; http://www.motorcycle-superstore.com/2/9/197/27986/ITEM/PJ1-Engine-Paint.aspx Not necessarily from them , but it is good paint. Cheers brt650

Thank you for everyone's comments. I have the backing plate away at the moment being sleeved. With over 2000 views I believe that maybe there are a few issues regarding the brakes that others would like to solve or see solved. Just on one note though- I think Ross (mrb505) has a valid point . Had I not bought the Honda I would have kept riding the bully with no concerns about the brakes.Anyone want a Honda? Thank you again for your input. Cheers brt650

Thank you David and Mark for your efforts so far. I'll wait if you don't mind David, till you have tried them on your backing plate. When you sit the shoes into the brake drum , can you measure the gap at the cam end please? When the shoes are butted together at the anchor end. Thanks again Cheers Brian

hello pschrauber, I don't doubt what you say , but I have a drum brake Honda and it;s very good. There are other's that would back me on that. And it's 110mm in diameter and the bully is 125mm. Doesn't make sense.I'm still going with David on this one and pursue the Fantic shoe/anchor design. I'll keep you posted.I think maybe the riding style in twinshock is different here to what they do in England. We don't have flowing as much , as stop and attack an obstacle. Much like modern style riding is.But a long way away from that.If you watch the guy's on Honda's at our club days at what they can do with there brakes that work. It would nearly make you think about changing brands. Heaven forbid. Thanks brt650

Hello reginald, I was hoping you would say they are great brakes. Cheers

Thanks for that David. I think we might be onto something. Thank you b40rt for your part number listing.

Hello David, That would be great if you could try those shoes to see if they closely fit the Bultaco backing plate. I don't mind buying a set .I can modify the anchor end if need be.Maybe you could ask Mark to service his brakes and while there apart, see how close a fit they are. Thanks Brian

" im looking into a CRF piston" Please keep us posted on what you find out about a piston. The CRF150 is 70mm I believe. Cheers brt650

The front brake first and then I'll get onto the rear. I did read David that you were considering the Fantic 240 shoes in a post from 2008. (http://www.trialscentral.com/forums/topic/17506-sherpa-t-brake-shoe-pivot-arrangement/ ) Did you end up trying that? I was considering the offset anchor end maybe causing some side effects. I made a ring 125mm round and fitted over the brake to see what was happening. The shoes under varying pressure move all over the place. I believe your comments from 2008 would help alleviate this. Cheers Brian P.S. Mum sends her love

I have read some of the old posts about brakes and even contacted some of the members here on TT. But I haven't yet read were a Bultaco owner has brakes that work as efficiently as a Honda. I know that is upsetting , but come on how hard can it be? Bully brakes are 125mm and my Honda has 110mm. Is it purely the lining material? Is it design? Is it mechanical leverage? I have tried 1 Relining the brake drum 2 Bushing the cam pivot 3 Newfren shoes 4 Machining shoes to match drums 5 Centralising the backing plate when tensioning the axle 6 Venhill nylocable 7 Suzuki cam and 100mm brake arm Someone has the secret and I want it. Thank you for your thought's. brt650 P.S. Don't tell the Honda riders that there brakes are better.

Does anyone know how many of these bikes where made? Thanks

Hello xtzoutback, The bike looks great.Will it be available on a secret practice day for appraisal? I'll take the first ride thanks. Cheers Brian

Hello xtzoutback, Seems like no one else wants to look at your dogey bike.But to make you feel good I'm willing to have a look at it Send me a photo if you want! Cheers brt650

Hello xtzoutback, Just wondering , you might have this listed on the wrong forum. I know Toyota make a hybrid. Maybe someone there might appreciate what you've done. I just can't get to liking the idea that you wrecked 2 good bikes. Have you ridden it yet? I'm sure if it is a winning combination , why the Honda engineers went to all that trouble to make the RTL frame.I bet they'll get a kick in the rear if they are still employed there for wasting all that time and effort. But I guess you know more than they do. Hope the Toyota boy's enjoy it. Cheers brt650

Sorry feetupfun, Sherpa325 wouldn't let me give mum your e-maill address. Guess you know why I'm a bully fan now? Cheers brt650

Hello David , That sounds great. Looking forward to it. Keep an eye on Ross , I think he is a bit of a dark horse. See you then for sure. Brian

Hello David, I'll pass those comments onto mum. She will be most pleased. If it's al-right with you I'll give her your e-mail address. But please note that particular photo was taken in 1972. So she may have changed a little. Cheers mate. Brian P.S. Love to have you as my step father.Though I am allergic to Yamaha's.

Hey xtzoutback, Don't want to be picky , but your thread say's successful fitment of RTL engine. If it was successful why can't you kick start it? Not wanting to finish there. But I would love to see an original RTL250 one day,let alone someone like you that strips one apart willy nilly. I guess your going to hack away a good TLR200 frame and destroy the original RTL muffler too? Have fun with that project. Cheers brt650 P.S. If anyone wants to put up some money ,I'm willing to track xtzoutback down and make him apologise for what he is doing.

Hello Michael, Just measured my 159.I relaced my wheels with stainless spoke kits from Bultaco UK last year. From the very edge of the rim to the swing arm both sides is 37mm. The right rear spacer is 30 mm long. A centre line through the engine case's lines up with the centre of the tyre. By the way. Harley davidson motorcycles can have a offset of between 8 to 16mm from the centre line of the frame to the centre line of the wheels. I set my Harley at zero off set. I don't notice anything wrong with the way it goes around corners. Have a merry christmas everyone. Cheers Brian P.S. Hey Sherpa 325 any chance of you completing an event on your own twinshock bike?

Hello david, Thanks for noticing me at all.Hope all is well in QLD. I was actually born there. So we have more in common than you think. My avatar is a picture of my mum. She's 74 now , I can update the avatar if anyone wishes. Brian

Hello Bondy, The bike did turn out well.I've competed three times with it now and I find it great to ride. It's apart at the moment ,I'm changing to right side brake. Just can't get my head around it being left side brake. Also changing the crank. Fitting the correct one finally. Good luck with your bike.
