1800bigk Posted January 20, 2005 Report Posted January 20, 2005 I know this is not a drag racing question but it seems like most people with cheetahs do drag them so I am posting in the drag forum to get the most feed back. I Just a ordered a cheetah +4mm and was wondering about cpi big bore inframes and the carbs. Someone told me there may be a fitting issue. He said those pipes may hit the carbs. Said I needed out frames. I know out frames yield the most power but, I still ride with my buddies on backroads and trails and I dont want to be running around like a mad man drag racer with big pipes shooting out the side of my shee. the carbs are 35 pwk tia Quote
00BANSHEE Posted January 20, 2005 Report Posted January 20, 2005 My CPI inframes fit fine with the cheetah cylinders. They do rub on the filters though but I just wrapped the stinger part of the pipe back by the filters with header wrap and I could still run outerwears. Quote
badcompany Posted January 21, 2005 Report Posted January 21, 2005 I dont think you should have a problem with the cpis, ive heard of some other pipes not clearing the powervalves and stuuf. PS: I would run CPI small bores instead of the big bores. Quote
1800bigk Posted January 21, 2005 Author Report Posted January 21, 2005 I talked to cpi and they said the small bores are good to 440cc, the kit I bought is 472. Can the rockets flow enough for 472cc Quote
BansheeBrian Posted January 21, 2005 Report Posted January 21, 2005 Shit man I'm thinking about the exact same ssetup for my shee. Let me know how you make out! I think the 472 with CPI's would be killer. Quote

Southside Motorsports Posted January 21, 2005 Report Posted January 21, 2005 I run inframe Shearer pipes on my 10mm cheetah drag bike. w/ 39mm carbs. and the stingers only hit the left side carb just a tiny bit on the carb. top. The pipes make awesome power but they like very agressively ported motors. Quote
1800bigk Posted January 21, 2005 Author Report Posted January 21, 2005 Bizkit, are your powervalves blocked off? Quote

Big Blue Posted January 21, 2005 Report Posted January 21, 2005 Definately, I will post any questions and any dyno numbers that I get. 309729[/snapback] The guy that runs the local dyno builds them and he said he gets close to 90-100 out of them. Quote
Southside Motorsports Posted January 22, 2005 Report Posted January 22, 2005 yes, my powervalves are blocked off but...they will clear them even if they are on there. Quote
