which is only 1" bore ..........question is ,do I bore out a 276 to 1 & 1/16 (correct size) or find a 289
Won't make much difference around town.
Unless you are planning some motorway trips ?
Getting it running nicely with what you have got is probably #1 priority.
By then a 289 will have fallen into your lap !
Those Indian mikcarbs are quite small bore anyway. ?
Maximum fuel economy was the name of the game there, for many a year.
Be interesting to know what they actually achieved.
"The Motorcycle" (magazine) used to quote fuel consumptions at various speeds.
Many a bike could do 100+ mpg, if you kept the speeds down.
I often wondered who chugged around on a Vincent at sub 30 mph speeds ?
Or a BSA Bantam for that matter, for the 10 hours a tankful would last ... !
The 289 is listed some places as being available new.
At a fair old price, it must be said...
Premiers are a bit less than that - no comment on visuals.
