Hi, my UK A9 GTR1000 has developed a big problem! Its done 86K miles and is getting very noisy, when cold it rattles like hell but this soon settle down and it runs really well...but!
The outer RH engine casting next to the outer exhaust stud has cracked. Probably been over-tightened at some point and has driven the stud into the head, making a hairline crack. I noticed a slight oil leak when I bought the bike earlier this year, but assumed it was the cover gasket leaking, sadly not!
I'm now considering my options, as its a bit noisy and now leaking oil, what engine can I use to replace mine? Do the chain driven engines fit, is it possible to swap over the final drive parts/engine cases?
Or, what cylinder heads could I use, I don't really want to make a full blown ZX10 type of high revving motor, saying that I've already got the higher power carb tops and Neta exhaust.
I'm on a tight budget due to being out of work with health issues, I need my bike back on the road
Thanks in advance, all ideas greatfully welcome
