May I post this - minus your email address on the few Blast forums I know? Feel free to do so !!! If they really want to contact you it is an easy look up to the BADWEB to find you, myself as well - thank you for that answer, makes total sense. BUELLers: TIMING PLUG BREATHER (PCV) <100627> PARTS REQUIRED: Replace Timing plug PN 720 with a 5/16 x 3/8' Fuel Fitting from ADVANCE AUTO PARTS PN 323320.1 ... 3/8" hose and the length is determined by where you run hose to the catch container ... PCV Valve from a CHEV Sprint Metro 3 cyl. eng. or any engine close to 74 C.I.(1200 cc) ... Oil Air Separator H-D PN 25329-91(has 5 baffles) ... INSTALLATION: The PCV Valve is placed in the most vertical position ... You put the PCV in the line so the engine can blow air out, but not suck air in... Between the PCV Valve andthe engine you place the Oil/Air Separator ... PCV valve highest point and with a one inch spacing place the oil/aie seperator ... DISCUSSION: This is old NASCAR Technology and there are those that have proved on a DYNO that they are of no help and "i" can tell you they were not improvised properly !!! "BUT" that is on a DYNO which is not the same as riding down the road or on the race track with all the real world variables that can occur ... WHY DID "i" INSTALL ONE ??? To decrease the pressure in the bottom end which is the closest point to it with no modifications required to the engine cases ... There is something about piston rings sealing better ... Which IMHO decrease's base gasket weeping and blow by on the motor sprocket oil seal ... Another thought, a PCV valve in the transmission breather hose that will let the engine by way of the crank shaft seal suck air in(must put a filter on the end of the hose), but not blow air out(but "i" have not tried this yet)??? The K Models(1953 to 1956)had a valve(engine/trans.) which sucked any excess oil out of the transmission because they had a "DRY CLUTCH" ... The IRON HEAD XL's(1957 to 1989) and did not have this valve(engine/trans.) and had a problem with the engine oil getting in the transmission, oil soaking the dry clutch ... EVO XL's 1990 to date have a wet clutch so engine oil getting past the motor sprocket seal are not a concern for clutch operation(but too much oil in the transmission is not good !!!)... If you have questions, feel free to ask them ??? "MAY THE OIL WEEPING BUELL NOT BE WITH YOU !!!" NOTE: If you a BLAST, XB, or have updated your rocker arm covers(TUBE FRAMERS) and have WEEPING(LEAKING)problems with the GROMMET PN 17606-00YA ... The "CURE" is to use "YAMABOND" which can be purchased at your local YAMAHA DEALER ... In BUELLing LaFayette Thank you EZ | ||

EZ, Exactly what should we be doing to the Blast engine? KennyG | ||

It's a performance option for installing a crankcase breather - non-leaking, and a mod to better seal the top end grommet to stop it from leaking - to better glue it with bonding sealer to keep it in place and not leak. EZ |
