Hey lizard84, I hear you gave Steve and his Duc quite a push start at the start of the 350GP race... good to see you haven't snuffed the 4-stroke boys.
Happy to be of service... Snuff the 4 stroke boys? never happen! If fact, my 2 stroke days may well be numbered, I had a few RZ problems, minor but problems none the less which really rammed home the point that racing the GS, the RZ, plus doing tech & grids leaves no time for tuning the RZ. I'm not going to stop working as an offical, or get rid of my GS, so something has got to give. So I may just start parting the beast out on Ebay later this week. Anyway, it was great to be involved with Wera vintage racing again. You will be seeing more of me.
What kind of problems? I hope it was nothing serious. Once set up, you should be able to run w/ minimal jetting changes.
