I've got a couple of these kicking around,I've sorted the fuel issues out now and want to try on my on my tuned Indian barrel.Anyone got a tried and tested spec for both bigbore and expansion.
I know the jjh needle is commonly used bit is that just on a reed motor?
Cheers

My experience has been with the OKO pwk and I found that the GJH needle worked better than the JJH which tended to be boggy in the mid range. The GJH is slightly weaker between 1/2 to 3/4 throttle so runs cleaner.
