Old Gezzer

Hi, We are currently paying around £6 per gallon for Fuel. !!

Back in the early 80's I used to ride a true Pre 65 Cub. No fancy Dan bits, It had a trials box, std shocks inc poor ground clearance, Heavy weight Std Triumph forks, Very poor brakes, 199cc Squre Barrel and head And an Amal Carb. Oh and it had points so no electricery ignition sytems. It was great fun it was the rider who got the best out of his bike that did well. I also rode a Rigid D1 Bantam, Not a lot to fiddle with there it was FUN. Rode in overalls and steel toed wellingtons. Does any one else think the present situation with "Pre 65 " bikes is more like my Dick is bigger than yours and I have loads of cash to make a Fiddle bike. I learned to ride on a variety of bikes when I was around 12 to 13 years old. One of the bikes was a 500T Norton now that was a monster of a bike. Again I think that back in the Day it was the rider who got the best out of the bikes that were available at the time. I agree that the bike should only be "Modified" with parts that were genuinley available in period at the Time. I know that things move on but how long before some one goes Fuel Injection and Electric Start on a Pre 65 bike ??? 🛠️

Have you tried Inmotion in the UK? https://www.inmotiontrials.com/product-category/parts/twinshock/bultaco/seats-bultaco/

I have put my restored matching numbers 198A. It has not got a V5 and a prospective buyer has asked if it could be registered? Thanks in Advance

Thanks for the help Lorenzo. I got my 198A from Norfolk last year so probably not to far from you.

Hi, Just replaced the Amal Carb on my 198A that I have restored. My question is. Is the choke on the Mikuni when the lever is down or when the lever is up? Cheers

Nice looking Butaco. A credit to you for the Resto. 👍

The Bultaco logo on a 198A and 199A model have a raised border as in the photo. There is no reason that the case will not fit just i believe it is from an earlier model?

My 198A has a different profile around the Bultaco badge.

Hi, A Clutch Case that came with a box of mainly 198 engine parts I just bought.Anyone help with which model or models they are off? I think we can ignore the black paint!! Thanks in advance

Hi, Have a look on the Web for Wax Jacket Refurbisment. There are a few on there

Hi, Found these people on Tinter web. Wax Jackets Cleaned Unit 5a, Marcliffe Industrial Estate, Macclesfield Rd, Hazel Grove, Stockport SK7 5EG 0161 484 2002

Hi, Firstly many thanks to all who gave me the helpful advice. Next, Rebuilt the carb after cleaning with Carb Cleaner and fitting 4 new jets as per Lorenzo's advice. Bike now starts, runs and ticks over. The tickover screw is fairly well nearly screwed all the way in. The needle is in the middle of the 5 grooves, If I lift the needle one groove will it give me better use of the tickover screw. 2nd Question, Where do I need to be with the Air Screw? As a starting point how far should I screw it out from it been fully screwed in? When should I know if it is correct and running sweet? Thanks in Advance.👍

Hi, Thanks to all for the input. I have stripped and checked the carb again! It is jetted with the same as specified above. Given a good clean with carb cleaner and a can of compressed air. I found 2 blocked jets. The needle Jet in the bottom of the carb body and the Cold start Jet which took some finding in the bottom of the float bowl. The numbers on the Carb are "L 2627" and 401. 4 new jets on order so we will see how we get on at the weekend. Cheers.

Hi, Just nearly at the end of Restoring my 198A. And I have a problem with the Amal Carb. I cleaned it out after soaking it in parrafin for a couple of weeks and fitted service kit to the carb but the bike will not fire up off the carb. If I tip a little fuel down the plug hole she fires straight away. I have fitted a new needle valve and checked the float is operating correctly, that is shutting off the flow of petrol when bowl is full. I fitted a new needle in the same position as the old one i.e in the middle grove of the 5 grooves.And if anyone has a list of the correct numbers for the jets that should be in the carb that might help. Any help or advice would be appreciated. I have been advised to bin the Amal and buy another carb but I would like to keep the bike original. Thanks in advance.

Inmotion are a very good supplier of quality parts for both Twinshock and Mono Trials bikes.

Hi, From what I know about BSA's the C15T engine number denotes that it is a 250cc Trials engine. But check that the "T" has not been added. My late father was at one time Clerk of The Course for The Scott Trial when it was organised by The Darlington & District Motor Club, that would have been in the 1960's. The BSA factory used to loan the club a works C15T to use in setting the course out. Steve

Hi, I think the "Herstellungsdatum" is the date the tank mold was made. There is a date under the rear of the tank as Lorenzo said and it is for 1980 which I would assume was the year of the tanks manufacture. I have just dropped the tank off with my painter so I will have to wait and see how it turns out. Cheers Steve

Thanks for the information everyone. I think for now the Tank will go on a shelf. Cheers Steve

A bit further on. Ignition side of the engine is done. Bars and levers loosely fitted Mudguards fitted. I have had to shorten the rear stay on the front wheel by 23mm dont know if anyone else had an issue with stays from our major Bultco supplier? rest of the assembly is ticking along nicely and hopefully not to much left to do. Main jobs are get the tank sealed and painted and cut and repack the exhaust. For some strange reason the site wo'nt let me upload a photo?? Cheers Steve

Cheers Lorenzo, I have a date of 1980 on the underneath of the tank. Steve

I got this tank with my 198A that I am restoring. I believe it is Fibre Glass [Not Good] and has a push fit fuel cap I believe it could be a period Sammy Miller item?

Hi, I have got a hold of what I believe to be a Late Model Sherpa Plastic Tank. Can anyone confirm this please?

Hi, Bit of an update. Over the holidays I have assembled and fitted the engine. New Big End and Rod Kit, Rebore, New Piston, New Fibre Clutch Plates. New Front and rear sprockets, All new Stainless Fastners. Fitted both tyres and got on with quite a few other cosmetic jobs.

Hi Woody, Thanks for everyones help. I have a 198A that I am restoring. It came with I think a period Sammy Miller Fiber Glass Tank which is shot. I also have a correct Plastic Tank which needs painting as it is well worn. But I am concerned about the ethanol issue taking the paint off.
