03 yz450 exh cam in my 99 yz400f, what is needed?

5 posts in this topic

I went to my local dealership & purchased the 03 yz450f exh cam & a plug to cover the decompression lever opening. Is there anything else I should do to the bike when it's torn apart?

I purchased the bike probably 6 weeks ago

I would get a new cam chain and consider a new tensioner. It will save you money down the road.

cool, I will order them tomorrow

anything else?

I was thinking of upping the displacement to 430 or whatever is available but I figured that would be more $$$ then I should dump into the bike

If you bought the $3 rubber plug from Yamaha throw it in the trash and get the TT decomp plug, it will never blow or fall out like the rubber plug from Yamaha.
