NH350 sprinter - latest

Postby BryanLambert » Mon Jan 15, 2018 4:50 pm

The bike is now in a rigid frame, the brakeless front wheel is an eBay “find” which fitted straight into the forks! 30mm Amal Mk2 carb, 1960s Wassel tank from the original sprinter.. started second kick. There is still some work to do, fitting a rear brake and rear set left-side footrest. Sprocket cover is a speedway item fitted to serve until the finished one is available

Hmm, a least one brake would be a good idea - even on a sprinter!

There is another front wheel, a pair to the rear wheel, with 8” alloy single sided brake; sprinters do need two brakes to pass scrutinering.

The brakeless wheel is for vintage flat track and grass track. Rear brake only for flat track, no brakes for grass track (probably run on methanol for these, but petrol for flat track)

Always handy to have a hole in the primary cover!

I imagine that was for an electric hand-starter. I’ve seen photos of this bike in Sprint trim with rearsets that foul the Kickstarter arc

It might have a grease nipple fitted to the cush drive. Nev

There’s no grease nipple. It’s probably just to allow the nut to be checked for tightness between runs

That hole might be there because a nut tried to escape ;) - and I think I see a 500 twin chaincase inner with the mod that lets you use a twin chaincase on a single!!

I did wonder about the chaincase... no, the hole to check the nut tightness, or to fit a spanner to rotate the crank while re-timing the magneto is quite a common feature of sprinters, since the ACU SRs required primary chains to be covered.

I see a WL motor hiding behind the Ariel.
