Hi grcamna2,
The engine has new pistons, rods, big-ends/mains etc. As these runs were only heat cycles prior to some dyno time I wanted plenty of oil getting to the new surfaces. You should have seen the smoke billowing from my garage door, I was lucky no one called the Fire dept.

It has now been run "chokes off" an there is far less smoke.
Hello scottly, The chassis is a reproduction of the Seeley T500 frame produced by a chap in Peterborough, hence "replica". I did have an original back in the day (1980/81), wish I had kept it of course.
"Zunspec" is the name of the 250cc Starmaker engine special that I started racing on which used a Zundapp frame hence Zundapp Special. I have used it as a moniker ever since.

Cheers Geoff
