Hi can you use a series one engine casing when building muggy 186
Thanks

Yes but you need to change the mag housing.

Thanks mate

Got to ask, why is there a need to change the Mag housing?

Mag side crank bearing is lubricated by 2 stroke mix on series 1 later ones are greased and sealed stickys book explains it better than me

I did a very early s2 muggy its worth noting that the two main exhaust studs are m5 not m8 like all later casings plus no extra exhaust fixing underneath engine

Cheers for that lads

There's a few tuners that will disagree with having to change the mag housing. Speak to Charlie Edmonds or Martin at chiselspeed. I'm sure they will tell you to stick with what you've got.

The only Li cranks to use the oil mist to lubricate the flywheel side bearing were on the Series 1. Those cranks also came with a bushed small end in the conrod, so that would need to be swapped for a Series 2 or 3 conrod for starters.

Hi i was going to use mec crank for the engine build
would i be able to use original mag with this crank
I was going to buy new mag
Thanks
