Hmmmph The Jitsie site no longer shows the 51T variant. Neither does S3 (don't think they ever did one) I did look when we had the old bike with the smaller chain and remember a 51 in Jitsie for sure. There is a 52T listed. You might have to bite the bullet and get one made. https://www.motorcycleraceparts.co.uk/motorcycle-chains-and-sprockets/bespoke-custom-made-one-off-special-rear-motorcycle-sprockets/

Jitsie do an EM rear sprocket for the smaller chain size in a range of tooth variants. Splat shop sell them but are out of stock on all but the 55T https://www.splatshop.co.uk/jitsie-solid-rear-sprocket-4-bolt-428-pitch-electric-motion.html?srsltid=AfmBOoo28NUBvJw_1_RLu4wrbq0-NU8ANVXhpK9ORKej5Dh_TD-ohhUPoLM Might be worth asking if they are planning on gettig the 51 any time soon?

That means the frame is from a Bultaco model 199A. The 7895 in the number means that is the 7895th one made. The 199A is a Sherpa T 350 nominal capacity 326cc and made around 1979. Blue frame and blue plastics. The model before it is a 199. The model after it is a 199B.

Hello you can test the thermo sensor in a pan of boiled water and use a multimeter set to continuity on the terminals. As regards the clutch if you are on a budget you could just use the bike and see how it goes, and slip the clutch a lot to encourage them to comply but personally I would bin them and fit new plates. Regards Alan.

Try Haase low friction sprockets sold on ebay by hanson-racing , they are on facebook also

I have a Bultaco with frame # JB-19907895-A . only info I have. Any inffo on what the numbers mean would be appreciated

Thank you.. I had watched it previously and it's a bit too grainy to see which way the bearing is facing. I spoke to his partner Jesse and we came to the conclusion that the metal side goes against the backing plate.

Search on you tube for jim snell video's. He makes one for the clutch only. For 1995 thru 2001 models. You should be able to see what you are looking for.

There's a line for Country on the inquiry form, so it would seem they sell outside the US too. https://www.rebelgears.com/ordercustomsprockets.html

Got a couple more questions as the bike takes shape, the cooling fan or rather the thermostat/sensor any ideas what the resistence readings should be or how long it would need to idle for before the fan kicks in? My sensor was reading 8 MegOhm reducing to 4 MegOhm after about 10 minutes and the water hoses and rad were all hot but no fan , I know the fan works as I have shorted the sensor and it ran fine. The other issue looks like the clutch plates have swelled due to the water in the oil , any ideas what thickness a new friction plate should be and if i could take a grinder/file to them to reduce them somewhat? The bike starts but clutch drag means I cannot change gear when the engine is running so need to rectify this before I can try the Techno out anywhere apart from my back garden , TIA

The needle bearings are exposed on one side only. I did not take note on disassembly. Do the bearings roll on the tappet or the backing plate... Thank you in advance.. Jeff

I had a really good feel for my old (2021) bike with a 51T sprocket on it. Foolishly I left it on when I changed the bike, thinking it would be easy enough to get another one for my new (2023) bike. It's not. I can't find one anywhere. Does anyone one have one to sell, or know where I could get one? 51T preferred but I would go with 50T or 52T too.

Tried that but never got a reply in fact he did not open the message! Facebook Messanger is notorius for not flagging up new messages especially first time contact.

Jon is on facebook, maybe message him ?

If you're in the UK, Birketts will be able to do it for you.

I have since come across a pic of a second ISDT Saracen ridden in the 1972 Welsh 2 Day Trial by Steve Wilson who retired after crashing. The reg letters appear to be GJH but actual number not clear, so probably GHJ 59K or 61K . Does anyone have any other pics of that bike?

Is the telephone number for Jon Bliss (01242 239055) still valid as I have tried phoning him several times on that number but no reply and does not go to voice mail. This thread is 19 years old so he may have changed his number in that time.

Thanks @feetupfun, I didn't know that, and it sounds promising because it explains dry cylinder and plug. I shall try and undo my actions, and will report back. The new carb is a VM26-8074 from Motocarb.

Are there any riders in central Ohio that would welcome a newby into their group? Looking to get back into riding trials again, just wanting someone to ride with and show me the lay of the land. thanks

There's a few possibilities here. Most likely is because you have wound in the idle speed screw, the slide might be too high for the start device to function. If it's a modern carb, the starting device is not a choke. Modern starting devices use the pressure difference across the slide to draw fuel through the cold start circuit and if the slide is too high, not enough pressure difference will be generated while kicking, to draw fuel through. If winding the idle speed screw back out again doesn't solve the problem, narrow the range of possibilities by putting a couple of drops of fuel into the cylinder via the plug hole, then see if it fires.

got a manual for a 2017 happy to send it to you PM me your direct e mail addrress and I'll send it via wetransfer
