TV Crank

[drivera]

Trying to fix a mates TV175 and its apparent that his crank is knackered around the keyway , thinking of upgrading to a GP crank so question is does anyone sell a GP crank with a TV conrod or would it have to be custom made ?

There are a few companies making quality 58 x 116 GP tapered cranks, including AF, Casa Performance and SIP.

Buzzsolomoto used to sell them.

Value for money would be the Tameni offering, next would be sip, then bgm, after that u need a small bank loan

If the TV 175 engine is completely standard & the intention is to keep it that way, then by exchanging the OEM crankshaft (unique to the 175) you will alter the balance factor.

IMO & experience the TV 175 was one of the most delightful engines produced because of that. That would explain why Innocenti persevered with it, rather than 'rationalise' production & fit the shorter con rod Li type.

If not a new replacement, I would suggest place a WANTED on this site for a used one before committing to any alternative

I have just done exactly that to my standard TV175.

I got a GP taper crank off Martin at Just Lambretta.

I went to 116 x 60 stroke too and in my opinion the TV performs even better than it did with the 116 x 58 crank that is standard. It has lost none of its low down torque but has gained a bit more on top. 1mm base gasket and a 1mm head gasket with 1.2 squish. Love it

Speak to Scotty on here he’s good with cranks

You should also consider a new flywheel if the taper surface has been scored badly.

Look around and I’m sure you can find some remade 58x116 ones. I run my TV175 with the original crank with a lighter electronic flywheel(the only upgrade) so I’m not worried about the tapper snapping.
TV cylinders with Suzuki TS185 pistons are a very easy conversion if you use a 60x115 crank and if you want to go in that direction.
