CBAIER1206 Posted January 15, 2009 Report Posted January 15, 2009 Okay so I'm on my second goround assembling my 421 cub motor after a recent trip to glamis...I had a slight film of grime under the base gasket which I suspect was a leak so I tore the motor down and am re-doing with new rings, gaskets, etc. My question is this, I am using 1211 sealer on all gaskets as per mike at cascade's direction but should I also apply it to the surface of the intake boot that attaches to the intake itself? I wasn't sure because the intake boot is rubber and thought that would make a good enough seal, However, I want to make sure it's right also. I will be leak testing the motor when assembled...I went to ace and built my own tester (mad props to RNBRAD for his how-to) for 40 bucks after calling a local bike shop and being quoted 300 bucks for something I built myself!!!

Bansh-eman Posted January 15, 2009 Report Posted January 15, 2009 its never hurts to add it to any mating surface. On my Boss intake it was required becasue the rubber didnt have a raised area to act as an oring and it leaked. I would just use normal hi temp rtv on surfaces other then the cases. Quote

Mike is a great source of information! I am not sure what type of intake you have. If it's aftermaket and uses a Mikuni part numbered boot, then the answer is no. If it's OEM or something else then the answer is yes. :geek: Quote
Dave I. Posted January 15, 2009 Report Posted January 15, 2009 I use grease on the base gasket and reed gaskets, and if you have white knuckle style intakes, there is a good chance they will leak and you will have to put some sealer on them. Quote
CBAIER1206 Posted January 15, 2009 Author Report Posted January 15, 2009 I have billet intakes that I bought from cascade and I also bought my rubber intake boots from them as well. Quote
