Great article packed with useful information. Thanks for the tip Martin.

Hi Martin, I'm afraid I missed the 200 PECO post you mentioned. I'll take a look at it though and give it a thorough read. Don't know where I picked up the Suzuki 185 info from either, all a very long time ago and looks like I have got some wires crossed.

Hi, the standard bore is 54.0 mm so if the piston you have is 61.7 mm, it's been well overbored. It's not a PeCo (?) modded engine is it ? They used a Suzuki 185 piston to up the CC's to 200 or there abouts. Are there any other obvious engine mods visible ? A sandwich spacer on the timing side for example.

A leftover from Only Fools and Horses ?

Put the video on Youtube and post the link to it

Hi Martin, many thanks for your expert advise. A stripdown really does look unavoidable whichever way I look at things. Phil

Well, with the modded ramps (Big balls), Barnett carbon friction and the matching steels, mine doesn't. So there you go b40rt, now you have ;o] Even my 125, which only has surflex sintered plates, the clutch on it doesn't drag either. Still, that's not the reason for the section difficulties which is only getting worse with time. Looks like I'll have to split the engine again anyway cause if something is worn or needs adjusting..........

Hi, afer I rebuilt my TL320s motor, gearchanging was a dream. It stated getting problematic going down the box especially from 2nd to 1st. Now it is also a pain going up the box from 1st to 2nd. The clutch isn't dragging so something with the pawl setup seems to have changed. Any ideas ? Phil

Hi, I'd give Bob Wright a ring, he can tell you what you need to know about Fantic spares and their availability. If you have contacts in Italy, no problem whatsoever, you can get hold of whatever you need there.

All three of mine are the same. Maybe yours had a metal tank originally. The fixings for those are different. Don't ask me how they differ as I have never seen one to be able to compare.

Here you go.

In my picture above, the second one, I show the sprung loaded, sliding latch from below. Looks like its missing on your frame. At the top the spring and at the bottom the tab to operate it. Not really as clear as it could be.

No need to drain it, lay the bike on it's side.

Here's some pics for you.

With a decent press, no problem at all removing and replacing. No press, lots of pickin and fussin about ! Drill the rubber out and cut rhrough the rest with a fine hacksaw to be able to remove the inner bush. Or use heat to burn the rubber away. Then cut through the length of the outer bush a couple of times carefully avoiding cutting into the swing arm. Once the outer bush has been carefully chiselled out, use a large vice to press the new ones in making sure that you have the innerside of the bush flush with the face of the swingarm (where the engine casing sits)

S3 Hardrocks.....fit just about anything.

Try these........https://www.amazon.co.uk/Mark-Todd-Competition-Number-Bib/dp/B004MY8UQQ and leave the bike untouched.

Your biggest problem is the lack of details.....A Bantam is not just a Bantam. Is it bog standard, has it been modified loads of things need to be taken into account. https://www.google.de/search?q=BSA+Bantam+twostroke+mix&client=firefox-b&tbm=isch&imgil=LGWyBZ9QgN2A7M%3A%3B9R34zc7JS9eJzM%3Bhttp%253A%252F%252Fwww.bsabantamclub.com%252Fforum%252Fbantam-technical-archive-faq%252Fpre-mix-ratios%252F&source=iu&pf=m&fir=LGWyBZ9QgN2A7M%3A%2C9R34zc7JS9eJzM%2C_&usg=__h7vmvxS_u6FtLHyW6Bd4gboYM5g%3D&ved=0ahUKEwiswIj_tszUAhUMrRQKHfPEABMQyjcIPg&ei=uxVJWez2NYzaUvOJg5gB&biw=1536&bih=740#imgrc=LGWyBZ9QgN2A7M:

Your best bet would be to cut through the middle of it, wobble the left side out and put a set of mole grips or other on the bit left screwed into th frame and with a bit of heat and persuasion, unscrew it. A replacement would cost around 110 quid with all bearings and seals etc. Don't go for a stainless one, stainless is soft and the needle rollers wear the shaft really quickly. Sorry for the confusion caused but working from memory and digging in the archives back over 20 years......

Download the pdf in this thread and you'll see what's what.

Hi Clive, the rear engine mount also clamps on it. Plus it is screwed into the frame. Been a long while....

Hi Clive, it's not threaded but there's a pinch bolt which can get overlooked. There's a nice exploded drawing in pdf format in an earlier thread which will answer loads of your questions I'm sure. It was to do with a 240 gearbox. Phil

The 350 Trials is a real lightweight at just over 138 Kilos.......picking that up on a bad day would be sport enough for two or even three !
