WHAT'S THE BIGGEST BIG BORE KIT?

8 posts in this topic

The biggest piston I've found is a 98mm JE (453cc). It's a special part made from a TL1000 blank, and a bit more of a pain to install than the regular 97mm.

You can also increase the stroke by 4mm, which will give you a max of 484cc. However, rod life becomes a significant factor...

HTH, JonE.

I'm in the UK, afraid I don't have any suggestions for getting the parts in the US.

Sadly the British distributor (Phil Allen) passed away a couple of weeks ago, but you could try this German site for info... www.bergos.de

What is the biggest big bore they make for the old 426? Who makes it? $? what all MAJOR modifications do you have to make? I don't want to have to make HUGE modifications. The biggest I've found so far is a Wiseco 450cc kit. was wanting like a 500......

Be careful, the biggest baddest will also give you the shortest lifespan as others have attempted.

The 450 kit seems to hold up real well.
