lol, good rant Graham. I finally started messing around with mine this season (got it a while ago when it seemed like everybody started using them and talking about tuning by temp). Seems like i can jet waay low and keep it under 400 on the vespa engine with Si head, def not going by that lol.
Only seized one time going down hill on my puch, turned out i'd put a hole in the shitty rubber bing filter coupler when i was putting it on. I usually run my stuff on the rich side though.
