dlnoss Posted January 26, 2005 Report Posted January 26, 2005 It depends on your riding elevation, if you are ported, and if your timing is advanced. In the other thread that I think you are referring to, he is at around 4000' elevation. If your compression is over 160, maybe less depending on your other mods, you should run fuel with octane greater than 93 Quote
Leadfoot350 Posted January 26, 2005 Report Posted January 26, 2005 you need race gas for sure at least 50/50 but, lucky for you the rebel gas stations have it in the pump somewhat cheap. Also you need to weld you crank as soon as posible or between seasons before it blows up and cost you tons of money. Quote

1800bigk Posted January 27, 2005 Report Posted January 27, 2005 No, you dont need to go out and weld your crank right now. It is just beter to do that because all two stroke crank will seperate over time and the more power you make the more faster it happens. You can take your jugs off and measure the amount of seperation (if any) that you have. Use the clymer manual. I have buddies that have had even thier welded cranks seperate, it just the nature of two strokes. Measure your crank seperation, if its within limits then your good, if its out of limits fix it cause it can become problems down the road. Quote
dlnoss Posted January 27, 2005 Report Posted January 27, 2005 so that means that i have to weld my crank just cause i run noss head with 21cc domes, with 160 P.S.I, and 103 octane gas?? No, if you were running smaller domes with higher compression it would be wise to have the crank welded. Quote
2stroke_addict Posted January 27, 2005 Report Posted January 27, 2005 No, if you were running smaller domes with higher compression it would be wise to have the crank welded. 312813[/snapback] thanks dave, again you are a life saver. Quote
smartsshee22 Posted January 28, 2005 Report Posted January 28, 2005 Dave is definetly the man. I had a problem with my cool head leaking into the cylinders and he has offered the best advice and customer service. I had to send mine into him less than a week ago to make sure it was not the head and I just got it back today. Very fast turnaround. So far my problem is solved. Thanks Dave. Ken Quote
