Definitely not a 2008 model as they did not have the early generation chrome frame. I concur that the header pipe is bent , also that coolant hose is not the correct size/shape oem part either . best of luck
Yeah, the frame nr. is *
VNBS108TR3009755* so should indicate it really is an 03
But luckily got to bend the pipe and the cleacence is 3-4mm, so not the best but it's not touching anymore! Maybe I'll change out the hose as well.
I was also wondering what the gearing should be, mine is 10 - 42 but in first gear and idle it felt a bit fast but I'm totally new to trials so I really don't know
If anybody has a manual for them, I'd be really happy, so far I've only found the parts list PDF but any other informantion is so hard to come by.
recently boughed a Sherco 0.8ST (add said 2008 but since it has 19" and 17" wheels I'm guessing more like 2003!!!)
But the biggest problem I see is that the exhaust runs next to the coolant line, do you think it's been hit or what's wrong... I'm pretty sure it's not supose to be that close!
If he's trying to torque the flywheel nut by a method other than holding the flywheel then he might be shearing it off while tightening the nut. And twisting the crank out of alignment too. I'll say this, he's got guts for even trying this. That expansion chamber's going to have a very strange effect with the trials engine porting.
No, I´m torquing it by holding the flywheel from the holes drilled and tapped. I´m not going to be really doing any seriouse riding with it, just want to finish something I started almonst 10 years ago! And planning to buy a proper factory built bike once I get this build sorted

Sounds very odd. That key shouldn't see any force if the taper is holding properly
Yes it´s shouldn´t but the original cracked when I forgot to tighten the flywheel and got it started the first time... so had to make a new one but I´m guessing it´s just isn´t strong enough, will try with a new one tomorrow!
Yes it's OK, it should have clearance the whole way along. It stops flowing fuel when the venturi effect stops which is when the slide gets to the bottom
Okay, thanks for that, I´ll buy new bearings for the cranksaft and but it all back together and we´ll see how it works.
Taking it apart I broke the flywheel alinging pin again! Don´t know what material I should make it next but hopefully another steel one will work now
Short brake again but I come bearing bad news...
I just had an idea to see if the cranksaft bearings are any good and found the Beta has a side-to-side movement in the cransaft... and as much as I know this shouldn´t be like that.
So today I took out the engine and cracked it open.
It´s wierd, cause everything has been changed not long ago, all the bearings look good and the seals also... so now I´m just lost, is it possbile the bearings are aftermarket and wrong size. They´re YOKO 6305.
GOOD NEWS!
It´s alive!!!!!!
Finished welding the exhaust today and once this was finished started playing around with the engine.
Turned out to be a bad ignition coil, it sparked a few times but then stopped working, once I changed it, sparks were strong and constat!
First start lasted 15-20 seconds and then ended in a bang and died. Tried to kickstart it again and the lever felt odd and engine sounded wierd also.
Turned out the flywheel came loos and also snapped the wedge so REALLY enjoyed making a new one -_ - smallest piece I´ve ever fabricated
Now the carb needs tuning and this is ...well, new to me
I think it´s lean, because as soon as I switched off the choke it died. Took it apart also, just to be sure that all the jets were clean and while I was at it, rised the needle one clip (now in the second slot from above)
The fuel that was in the tank had also sit for a year so called it a day, carb is back on and I´ll start reading about this stuff and will also take new petrol with me
Still really happy that it started after 10 or more years of sitting in pieces and hopefully the clutch and gearbox work also
Hahahaa, yeah, it´s really been awhile!!!!
I actually have no clue how it´s going to effect performance but at this point I´m just trying to make stuff happen.
Are you referring to the pipe size or something about the length, width...?
Well, this small brake turned into a year... almost
But, all is not lost, just been extremely busy and been dealing with all kinds of other stuff, today felt like a good time to pick up this build.
I haven´t been to the garage almost half a year, was happy to find everything in place and nothing stolen Now I finaly got gas for the welder and switched out the wire, dear lord, it´s a complitly different machine now!!!
Filled the gearbox with ATF and hopefully it will start working, so as soon as I finish the exhaust I´ll try to get it running before building anything else (maybe just the subframe so I could push-start it)
Made an exhaust flange from 5mm steel and cut up the donor pipes.
Now it´s starting to look like something...
Just need to properly weld it up and make a bracket or two and deal with the muffler once the subframe is finished...
Hey guys, haven´t posted for some time.
Tried to get the MX5 out of the garage only to find out the alternator had rusted shut, so took it apart and cleaned everything but it´s still not charging so I´ve been dealing with this and some mold + rust and well, just maintenace in general because I want to have it wokring properly although last year didn´t really drive it.
But, there´s heaps of space in the garage now, though I also have to rebuild the tail on my Jawa, because we´re going on an anual oldtimers ride in the end of this month.
SOOOO, a small brake from the Beta but will be getting back to it as soon as possbile.
ALL THE SPACE!!!!
Small steps after a long time.
Started on the exhaust, I´ll be basing it on a Husqvarna WR250 and hopefully make it fit.
The clutch is still a concern, even when compressing to lever on the engine it won´t fully disengage, so I´m quessing I should take it apart again and give it a proper cleaning, especially the plates between the disks.
Also tried to check the timing but the borrowed strobe didn´t work, so waiting on another friend to help me out
So close, but still so far
Buttoned up the engine mounts and got the wires routed, I´ll add some plugs and a propper wiring once everything is working.
Also made the starter button a kill switch, and made the clutch cable fit but I don´t have enough movement for propper disengagement.
The last owner made the linkage longer, so I´ll have to return it to a shorter version.
Still didn´t get it started and without the clutch I couldn´t push-start it either, can´t get enough grip on the concrete, once I get the clutch working I´ll take it on a field nearby or something like that!
I am just waiting for the first video of you riding it... When I get a bike I strip and rebuild. I replace what is worn or damaged and end up with an as new bike. I couldn't do what you do.
I must admit what you do is much more reasonable!!! I would go the same way but since this started so long ago it would be awesome to finish and I´ve enjoyed these last months too much
Was away for almost half a week and today was a short one, so made the kickstarter fit and tacked the front mount, hoping to get it running the next time I´m in.
I am enjoying the trip this has been, your enthusiasm for this build is great.
Thanks, I had forgotten the awesome feeling of achievement when things start moving the right way...and how much you can learn from every mistake
I´m loving it!
Today was a very work oriented day but squeezed some garage time in as well, had to clean up the place because I saw and add touring the weekend and couldn´t resist - so now I also have a Honda SLR with a gearbox problem.
One car and 4 motorcycle isn´t a good idea in s 3x6 space.
But luckily I have a tunnel there, so now there´s rome for actual work and I started with the front mount. Won´t be pretty but for version 1.0 I think they´ll do the job, some welding, a few supports and we should be golden.
Got the chinese ignition working and had a feeling I should try the motoplat again before gutting up the engine, because the impulse generator woudn´t fit otherwise.
So after taking it all apart and reinstalling the original parts I discovered I hadn´t attached the green wire previuosly and well, that was the ground for the stator ....
Wasn´t sure but had to give it a go and this time I made a 17mm socket fit a drill and when I got the engine spinning there was a beautiful spark!
Unbelievable how stupid I could have been, so now, I´m gonna tighty up everything, set the ignition and make the front mounts!
Even without the exhaust it would be the first time the wheels start moving on this badboy!
Didn´t get a change to visit the garage for a long time but today started working on a new ignition system, just thoughet it easyer and cheaper then messing with the motoplat!
Got a chinese pitbike cdi ignition and hoping to get it working though it will need some pretty seriouse mods.
Gonna keep the plate and had to also modify the magneto, because it woudn´t reach the cone.
The plate is also taking shape but now comes the biggest problem, the ignition doohickey is external and doesn´t fit the housing!
Also got a new project for summer It´s a Honda Dominator, so when waiting on parts or just get too frustrated I can work on that.
Raer mudguard from a GasGas TXT, will fit with some modifications so can start with the subframe and engine mounts. New grips and a clutch cable.
Still nothing from the ignition part, but I got the puller and seems like sombody has changed the stator, because it looks like there´s been some milling done there...
Finaly took the tyres up and got them properly on the rims, they´re straight now, will see how the tubless rear holds once I start ridin
The fuel tap and airfilter arrived which fit just perfectly.
Had to start with the cables since I can´t get the flywheel off, so orderd a puller and a new clutch cable since the one I had is sticking like grazy and isn´t a good fit, throttle wasn´t also a bolt-on... neither is it nice but works good.
With a new chain the bikes starts to look like an actual motorcycle.
Hoping to sort out the motoplat, but still have the front engine mounts and an exhaust on the list.
Okay, so no luck with the spark
Figured I´d try this one but nothing, also tried this with three different coils.
Finaly remeasured the resistance but also read that if you have diodes it´s pretty much impossible to see if the stator works like that, so you´d have to send it to a specialist.

Sucks that the kicker hits the frame, from the bottom photo it looks like it would clear.
Is it just barely rubbing the frame, or worse? If it is just touching, I'd be tempted to indent the frame at the wear spot with a sledgehammer and large drift pin.
It´s a the nut on the top and hits pretty hard, might think about gutting rewelding the frame so there´s room for it or maybe redo the kicker.

It would appear that you have a TR33 engine not TR32 you will need to find the proper wiring diagram and you will need to use the motoplat CDI box. Good luck.
I was never really sure about that, even contacted a guy on advrider and sent many pictures of the engine but he still thoughed it shpuld be a TR32.
Gonna try to wire in the CDI with a diagram found online but unfortunately can´t find a manual for a TR33
...........For those who have no idea what this relates to you need to study the pictures of the bike more carefully
