I just emailed you 3 different MAPS for a rich 331. I'm almost certain the 351 will work. Don't panic, just get it fitted & start playing with fuel cells on the power commander!

You might need to richen up these MAPS a little bit for the 351.....but it's only 20cc more.

Up to 60% throttle position my MAPS should be pretty good. The 3 MAPS are pretty rich for webcam101 performance camshafts & my airbox has a bigger snorkel with extra holes drilled.

It's quite easy to add 5-10% more fuel to a group of fuel cells. Keep saving new MAPS until your happy. Spend some time watching Power commander 5 tutorials on Youtube.

Good luck :cool:

J

I will and thanks a lot again Joel

Has anyone in the UK gone ahead with a big bore kit?
I'm looking around online trying to source the parts, but they all appear to be in the US.
I'd imagine it would cost quite a bit to buy all the parts especially with all the additional import & currency fees on top...

Yes it will. In my experience the Dobek EJK controller will deliver ample gas to the 350. ( it is only 20 cc more than my 331 )

Anyone knows if it is confirmed that the 351 will work with the 250 EFI model?

Be brave & go for it! I've had my 331 running way to rich & had to take quite alot of fuel out of the mix to stop my bike spluttering & get it running crisply.

I personally would buy a 351 kit & wouldn't worry about it working as an extra 20cc is nothing! It will :cool:
