Hi all, well I have braved the cold and done a little more, mainly the tank and seat unit. Here is what she looks like now.

Hi all and thank you for your interest, not much work done over the last couple of months as my workshop is too cold. What I have been doing is the motor and more problems found. I thought it strange that there was no drain plug for the clutch, what they had done was to fit the drain plug from the inside of the case and weld up the outside then blend it in? I spoke to my mate and he said to leave it as he doesn't mind taking off the case to do an oil change, not for me but his decision, so that's what I'll do. After fitting the clutch plates back in after checking, home made compression tool, I set about refitting the cases. What I found was where I thought a fixing screw had fell out and lost, there was a tap broken off deep inside and there was remnants of glue inside, they had glued a screw inside to make it look good, cowboys come to mind. The tap was in too deep to remove but there was some of the casing above the broken tap, fortunately it was a hole with the dowel pin so I got a spare dowel pin, scuffed the inside with my dremel, got a casing screw and put a film of vaseline over the threads and filled the dowel with jb weld and inserted the screw making sure it was compressed and let it set for a couple of days. First i removed the screw to check the threads, the vaseline worked a treat and the threads were perfect, then I replaced the screw, put it in the vice and attacked it with a hammer, it held really well before pulling the threads out and easily strong enough to hold the casing on so I did the same on the crankcase making sure that the casing that was left above the broken tap was scored enough to get a firm hold before inserting the scored dowel then repeated with a new screw making sure the jb weld was compacted in. It worked a treat and has got more than enough torque to hold the casing on. I hope this is the last problem but then again, I like working things out. More to follow.

Join a club, there are plenty dotted about. What you will find is that in trials it doesn't matter what level you are at you wont be judged, in fact you will find more riders close to your riding capabilities than experts and all will welcome you. Give it a go, you can't loose.

Hi, thanks for your reply. MOT is no problem as it is a friend of mine that owns the shop/garage that is local. In saying that, with the Bultaco being over 40yrs it is exempt, I will make sure everything is right on the bike but I don't think my mate who owns the bike will bother with an MOT but I will make sure it is road legal. More to come soon.

Hi turbofurball thanks for following the restoration. I am undecided weather to get some self adhesive plastic numbers or to paint them on, I think painting on would be more in keeping, as long as there tidy but what do you others think?

Hi all, even though it's so cold in my workshop I have managed to do a little more on the bike, here is an update. The rear mudguard was a real state, it was bent and cracked and I thought it was scrap but I decided to give it a go at rebuilding the rear section and fit a brake light, as it is going to be re registered I covered the end in leather ready for the new reg, not brilliant but I'm happy with the end result.

Hi all, I've got the forks rebuilt with new seals etc and also the front wheel and got them fitted. One thing that has pleased me is that all of the bolts for fitting the mudguard, after cleaning all the crud and rust from them, are original bultaco stamped bolts. My opinion is that it is looking quite good.

Hi ChrisCH, thankyou for your reply. It isn't the mounting rubbers I need, I have those, it's the internal seals etc that I need.

Hi all, I am in the process of restoring a bitsa Bultaco. The frame is a model 85 250 Alpina and the motor is a model 49 250 Sherpa. What I am after is a service kit for the rear shocks, I have looked in numerous places and can't find any, does anyone know where I might get them? Thank you all for your time.

Hi, here is a photo of the frame now it has had the paint and lacquer, my opinion is that it looks quite good. I do understand that the opinion of others vary, the same as Yamaha followers, but at the end of the day, I made the choice and am more than happy with the end result. As I said before, the bike is a miss match, the frame is model 85 250 Alpina and the motor is a model 49 250 Sherpa so this bike will never be original but it will be a nice looking bike that will give loads of fun. This one I am doing as a favour to a good friend of mine, he purchased the bike back in 1975, he was told it was all original and not many were made, it came with a log book and was registered for the road, he never checked the numbers on the log book, when I got the bike I checked on the DVLA registrations as the reg number was still on and it couldn't be found. When I ordered some parts from Pete at in motion, he asked for the frame and engine numbers to get the correct parts, it was Pete that informed me it wasn't what it should be. I got the log book from my friend and checked the numbers, the engine was correct but the frame number was different, my friend was gutted, he said that back then he just got the bike and was more interested in riding it rather than reading, he thought he had a gem when in reality he was stitched up. I will do all I can to put a smile back on his face when he sees his bike looking nice clean and fresh and one that he can bring back his youth.

Hi, thanks for your reply turbofurball, It is just personal preference, my opinion is that it looks that little bit better, more like original, and also with a 2K lacquer it is quite hard wearing. I will post a photo of the frame painted and lacquered.

Hi all, here are a few photo's of what's gone on so far. What i like to do is to etch prime before primer and then top coat and lacquer. the frame as is needs another top coat and then lacquering. The tank and seat are in primer. The forks are not quite finished yet, I am waiting for the new seals to come and then finish of cleaning. As you can see, I have cleaned some of the parts in the box but not all, I do my cleaning between other jobs. The wheels have not been touched yet but I do have new tyres for them. The motor has had the top end off to check, I didn't know that dykes rings were fitted to these, piston, barrels head all in really good condition, I have had the clutch out to check and all is good. All in all, the bike is in good condition, it had just been left for some years and the old rust had attacked it but now it's gone. This is the first trials bike that I have took on, in my retirement my hobby is rescuing old bikes from the scrap heap or breakers and normally I do old air cooled Yamaha's plus anything that takes my eye, I'm really enjoying this one as it takes me back to my trialing days and it wont be the last.

Hi, thankyou for replying. I will see if I can get some photo's done and put them on for you all to see.

Hello everyone out there in trials world. My name is Robby and I used to do trials back in the late 60s early 70s at my local meetings at Buxton, Matlock and Leak etc. I was never brilliant but loved every Sunday when trialing, I used to ride a mclaren suzuki, I wish I still had it now, I found it very light and easy to ride. I am in the process of restoring a Bultaco 250, it's a bit of a miss match but all there, I would like to thank Pete at in motion trials for all his excellent help and advise on my project, his service and aftersales is second to none.
