Finished A 198B At Last

By way of thanks for the Site member's help regarding flywheel size on my latest project, a very tired but genuine 198B, I thought you might like to see the bike in its completed state. The usual thanks to Dave, Pete and Robin at InMotion of course. Not ridden in anger yet, I use my 199A for trials, but it certainly revs very freely in comparison with the 350. I also managed to get hold of an earlier pattern airbox, which is a vast improvement on the correct 1980 pattern, easier to access and I think probably more water-proof. I used a modified Gas-Gas piston in the re-bore, a bit cheaper to buy but fairly tricky to machine the skirt and the inside of the gudgeon pin bosses. I am particularly pleased with the two-pack satin finish on the castings and the powder coated frame. I used Fastline Coatings in Preston, not cheap but very good.

I love Bultos but I might try an SWM next. Any thoughts?

Fine job to say the least!!!

Really looking good, the air box choice is good as the works riders seemed to prefer them instead

of the poor quality plastic used on our bikes.

I believe I see a VM26 Mikuni, also the better choice in my opinion.

Now you must go for a proper test ride & please report back.

Your M198B looks very good but one thing which improves the look a lot is to sand the ignition case down to aluminium where the thumb imprint is so it is shiny and do the same on the Bultaco on the primary case. This just sets them off. It makes the Bultaco and the thumb stand out against the black paint. Graham.

When I go into my garage, it's always the Bultaco's that stand out, why I don't know, I've tried to explain to myself, but I just can't understand it. Maybe it's the white frame and blue plastics, but everything about these particular Bultaco's just seems to be right. The big fin barrel and head loverly, the tank I suppose is to long and the seat to far back, but the bike overall just (to me) looks perfect. Maybe it's because 'the last of an era' starting with the radial fin four speed, every collection deserves a Bultaco.

Sorry forgot to add....yup SWM for next project is a great choice sir....they burned so bright for too short a time.....the yellow would complement the blue!
