Hi everyone, still on with my rebuild of the 248 and I'm having trouble sourcing a felt pad that sits on the stator plate to wipe the flywheel cam. I'm in Lancashire, UK. Ps. Tried Inmotion UK ..........no joy. Regards. Dave.

Thanks lineaway, The rear seems ok, i'll have a go at replacing the oil at weekend it cant be that difficult its just a case of getting stuck in, it never seems as difficult once you've started. If that doesn't give it more resistance then ill look at replacing the springs or manufacture a small spacer for the top of the station. Dave.

Hi everyone, I own a 2013 250 Gas Gas Pro, which appears to be running low and soft at the front end. I appreciate I am a rather healthy 16 stone in riding kit and that may have an impact, but before I look to deeply into this issue I want to check the basics and replace the fork oil with 7.5 weight. Wherever I look I always seem to find a measurement from the top of the compressed station to the top of the oil, surely there must be a quantity measurement for this, which would be easier, or am I missing something here. Also are there any firmer springs on the market for this model , or are spacers available to take a little sag out of the spring..............has anyone else had a similar issue which they have solved. Many thanks. Dave.

Thanks Spusdad, got hold of Kev at Kev breed on racing and he's pretty confident that he has got some that are almost identical. Paul, contacted Jared but he only had first oversize and no standard bore, but a good contact though. Thanks to all, Dave.

Thanks Paul, I'll email him tonight, thanks.

Hi Paul, Glad you got her going, did you manage to find some tank decals in the end? Thanks to all for the advice I'll get onto Southwest Montesa tmrw. Dave.

Thanks Australia, I've got the lads at Inmotion Bultaco UK, looking into alternatives from Bultaco etc to see if they're close. I'll just keep a watch on Ebay for someone breaking an engine as well. Your right there aren't many about these days, some 348s and 349s but very few 248s. Thanks for your assistance. Dave.

Thanks, Inmotion can't get them and the one on Ebay is piston etc but no rings, thanks anyway. Dave.

Hi, I'm having trouble sourcing a set of piston rings for a 1981 Montesa 248, the larger L shaped one on my bike has broken and they seem hard to find. Has anyone managed to source any, or had the same problem and found an alternative. the piston is the standard it's not been re bored and the cc is 239.3. Many thanks folks. Dave.

Thanks for the replies chaps........the website I found early in my search, classicbikedecals , that I couldn't open has now come back online and is under development. They do all the classic Spanish Marques and the 248 ones are £22.50 Admittedly that's without the round tank badges but I have those already. Thanks. Dave.

Can anyone help me find a set of decals for the white tanked 81 Montesa 248 that had the external pipe fuel gauge . I know Spanish Bikes site has them but at over £100, seems rather steep, when similar 348 / 349 ones are £40 ish in the UK. A site keeps coming up when you search the net for the above stickers of classicbikedecals but the site cannot be accessed????? I know I might have to just put my hand in my pocket and pay the above high price but just exploring other options before my pants are pulled down. Thanks everyone.

Thanks MONT 315 that PDF will make life a lot easier.

Thanks guys, what is the correct float level/setting for the tlr 200 please.

Thanks Rollox. I'm still running the original Honda exhaust, which Classictrial say works really well when used in conjunction with a well sorted carb. I believe historically my bike was a Californian import which makes you think it may be chocked up somewhere due to their strict fuelling laws, is there anything to be removed in the exhaust system? Or has anyone any comments on changing it to a WES or DEP system, or similar. Thanks.

Hi guys, Took the top off my TLR, cleaned the piston ,head and reground the valves, new seals etc. It had the original Keihin carb on it which was a bit past its sell by date, but I also got a replacement carb with the bike, a SHENG WAY, which are the cheap Keihin replicas I believe. None of the jets are marked with numbers? Anyway, fitted it but it has a fluctuating tickover. It starts and runs fine but settles at a tickover, then after a few minutes drops several hundred rpms and cuts out/stalls. Restart it and its fine again. The throttle cable is lubed and free and not catching anywhere I have had the inlet off it and smoothed it off with fine glass paper on a flat surface and fitted the correct O ring to prevent carb distortion. I've just ordered some new jets for it so we'll see how it goes with them in. Its a new Iridium plug and the timings fine.................anybody had similar problems or have a SHENG WAY carb fitted. I'm in the UK at sea level so its not an altitude issue. Regards.

THANKS TO ALL THE PEOPLE WHO CONTRIBUTED. GOT TWO NEW WEDGES AND AS I TOOK IT APART I FOUND THAT THE PREVIOUS OWNER HAD ONLY PUT ONE WEDGE IN FOR WHATEVER REASON. NOW WITH THE AIDE OF THAT VERY EXPENSIVE HONDA TOOL ( A SPOKE ) I GOT THE TENSION RIGHT AND LOCKED IT UP. WE NOW HAVE A VERY QUIET TLR.................NEW QUESTION BEING POSTED ABOUT ERRATIC TICKOVER. REGARDS.

Thanks guys, new parts ordered, will be here in a couple of days. Let you know if it's cured the problem.

Hi Craig , I've removed the locknut and found that the wedges are locked in position they are stuck fast. I'll probably order a new one as I'm sure they should have a small amount of movement prior to the locknut being tightened. Dave.

Thanks Craig, I'll see what condition they're in tomorrow, but that answers my question. Many thanks. Dave.

Thank you 4stroke, so the wedges you are talking about are in the lower casing where the tensioner bar sits, not at the top by the locknut?

Thanks guys, I,m interested in the two wedges that hold the tensioner rod in place, should they be in the locknut or attached to the tensioner rod because that would make absolute sense, something to keep the rod in place. I must be missing those wedges!! Are they shown in the manual. Thanks to you both and I,ll also check for cracks in the tensioner. Dave.

Yes, I've tried it with the engine running and not running, same result, it just seems to lose tension, like I said there doesn't seem to be anything in the locking nut to hold the rod in place to keep the tension. I could understand it if there was an eccentric or jaws that clamped the lock nut onto the tensioner rod to keep the tension but there isn't. As I said the head of the tensioner rod has a bugle type head and the inside of the lock nut is just hollow . I,m wondering if the locknut is missing something or the wrong one???? Thanks anyway.

Good morning, I know its an old subject and I have read the forum entries and seen footage on Utube but..................... I have tightened the timing chain as per instructions, which seems to be well within the wear parameters, by setting the timing marks to TDC so the chain isn't under load, releasing the 14 mm locknut, removing the 10 mm nut on top and pulling up on the tensioner rod and tightening up again. Fine..........fired up, sounds great until you load it with revs and it appears to release itself somehow. THE QUESTION.......the tensioner rod has a bugle type head to it ( by the way this is free and not stuck it will push up and down ), once you pull it up what holds it in place as I've looked inside the locknut which appears to have nothing inside to hold onto the tensioner rod. Excuse me for being thick, am I missing something or is the bike missing something, just waiting for a manual to arrive and I have an event tomorrow and wanted to try and fix it before then if possible. Regards. Dave

Thanks Chuck.

Hi guys, Currently renovating a Beta TR35 basketcase and the upsidedown chrome fork stantions are really pitted. I've realised that they are a small fortune to have them re chromed and i'm looking at alternative secondhand forks for sale. I've seen a pair of Aprilia 280 Climber( 92-94 ) forks for sale, from the photos they appear to be very similar to the Paolis that are on the Beta. Basically will these fit the Beta. If not are the Beta Techno forks the same as the TR35? PS. Read the thread about the scammer on ebay selling the Beta TR 34 parts....thanks. Thanks. Dave.
