I tried a couple of different pipes that I have seen reccomended on here. I used a 053 and a 086 made by Power Racing (I got a deal on both). I ended up going with the 053 at the small track I run at and think the 086 may be better suited to a larger track. Question is with so many mfg.'s now making pipes, how much different is, say the 053 between them all. Seems to me that the Nova 9853 and the Grp 2053 for example should be pretty close to one another. I had thought all pipes were spec.'ed by EFERA for the most part. Any help would be great because the price differance between some pipes is alot for what I would think are the same pipes.

GRP 2053 is in no way related to the 9853/053 pipes...the GRP pipe is a very restrictive 3 chamber pipe...

also try using differant restrictors i had a 8 in my modded and went to a sirio 7 and i got more run time ...i ran a 15 min main pitted at 6:50 and ran out at 17:40 with the temp at 176.....
nova 9853 pipe and p3 plug...

one more thing to think of i guess some rules are changing here in the near future with pipes from what the guys at fusion told me is the nova 9853 will be illegal for the 09 roar rules its to load so their making people switch to a 3 chamber like the grp pipe...boooooo lol if anyone knows about this let us know more....

That doesn't surprise me. The question is will they require 2xxx number pipes or go with full IFMAR rules and require 3xxx number pipes?

I cleaned it up before the last heat and again before the race and both times there was buildup of muck where it appears to be leaking. If you can pm me your number, or address. I leave Tuesday morning for a week, so i can just send the engine in for an inspection if that's ok with you guys.

On another note, thanks to the guys at revelation for helping me out and pitting for me, made my first race experience nice and fun! i was trying to look for you before i had to leave, my friend was in a hurry and i didn't get a chance to thank you guys. :tire:

here's an update,this should give you a better idea of what the issue is, i took the engine out, looks like its definitely leaking from the carb boot. i also snapped a pic of the front bearing, it appears the fuel was dripping from the carb down to the bearing as well.
