Not even a Yamaha but a BSA!

I do like an old BSA but couldn't afford a flat tanker so settled for buying an old Brit icon - a 1958 BSA C15 - to tinker with over the winter months biggrin 

It hasn't been started for about 8 years and have been told it wasn't an easy bike to start back then so I think I have a challenge ahead.

It's got the early "eyebrow" petrol tank which is good. 

Signs of oil on the head-barrel interface so I am guessing at least a new head gasket is needed. But I may clean out the tank and carb and try and start it first - after checking the old oil is clean of course! 

Now that the excitement of getting Steve's 350 big bore built and running is over, I need to do something a bit more relaxing wink

Not sure about the red. I am thinking of almond green and ivory two-tone.........

Great choice, Brian.

The original C15 was introduced in late 1958 and was derived from the earlier Tiger Cub, but enlarged to 247cc.

I have seen a fair few of them under the back end of lorries and buses due to the speed, lack of adequate braking and Learner egos.
Their front wheel and forks tended to bend underneath the engine's crankcase!

The road versionC15 was used as a basis for the competition models like the trials C15T and scrambles C15S.

The red is an original C15 colour scheme.

Knowing your expertise, Brian, I am looking forward to seeing the end product. wink

Nice bike. It looks like a Polish patrol fire brigade

So, when I took the head off, I found a Triumph 500 Speed Twin high-domed piston fitted!

I managed to get hold of a large inlet valved SS80 (an 80mph C15 model) cylinder head and a bigger 1" Amal Monobloc carb to suite, fitted new rings, put it all back together and the engine started easily and runs fine.

Nice to have a little bit of brass and copper on an engine to give me something to polish up  biggrin

It's now back in the workshop for some tidying up wink

I couldn't resist doing a blog - see http://www.ttr250.com/BSA_C15/C15_blog.htm
