Imola 186 piston options

[Shuggie]

Hi Guys

Picked up a 186 imola top end that either needs a replate or steel lined , whats my options if i go down the steel liner route......read somewhere i can use the piston from the GT 186 kit.

cheers

Not directly without alteration to crank rod length or cylinder height.

With a liner your options are open to increase the bore to 66mm and use a TS1 200 or Monza 200 piston.

Need to check reed valve to piston clearance on your version Imola - will it take an extra 1mm?

MBD may well also have suitable 'Racetour' forged pistons.

If you are buying a new crank for the project your options are wider.

Using the 'search' for similar questions to do some 'background' does not hurt!

More options if you take it out to 66mm and fit a TV rod, then you've got a choice of several RB20 pistons. As Yanker said though you'd need to check reed clearance.
I presume that you can take it out to 66 and have it re-plated rather than sleeved?

searched on old posts and thats where i saw you could use the GT186 piston , but not any other details about what needed done to the cylinder.
Fancy the idea of having a few rebores with the steel liner and at less than £50 a piston its much cheaper if anything goes wrong!

Not sure who can do the work but i'll phone around a few of the usual suspects!

Thanks for the replies
