    New Zeeltronics Y62T CDI

    I agree but I bet the IJSBA doesn’t see it that way at all. We all need to ask for clarification during the rules period in late December or early January

    New Zeeltronics Y62T CDI

    Hopefully this will get approved for IJSBA lites racing. Technically it is not legal with the programming input. I know the MSD has a positive red wire that isn’t on the OEM cdi but that’s not considered an input/output by IJSBA.

    New Zeeltronics Y62T CDI

    Gosh I hope reliability is better than all that have come before it. There have been at least 10 and the only ones that really stood the test of time was the first Vilder I remember talking with CJ deVilder and he said capacitors were the issue after his first generation in 93-95 time frame...

    38mm SBN questions (NOT OEM's)

    Yes I did. I didn’t have to but there was a time I was using them on my blaster and that has a remote pump with a Novi vapor separator so it’s mandatory with that setup.

    38mm SBN questions (NOT OEM's)

    Single feed and dual pulse. Only ever ran dual feed on 50’s on my 8mm dry piped race boats. I like to use the petcock so I keep it to single feed with normal builds.

    38mm SBN questions (NOT OEM's)

    On that setup I ran dual because each carb had a pump. Yes you could easily convert to one using oem backs

    Reed valve problem Maybe

    A little daylight is normal. Suck on them and they should close. They are also molded (layered) with a curve and coated. Maybe for last ditch hours it’s ok to flip but you may see daylight on the sides which isn’t good and won’t seal as well

    Looking for SN handpole / replacement help

    There was brand new 2019-2020 SJ take off poles on eBay for 200 I think and 50 for pad. Note steering and spring was included. Then buy a bracket (watcon) for that pole and you have a nice new setup way better

    08+ Stock Superjet Max RPM

    6460 was best I saw and if I recall it was April/March. 50f water or so and 60-70 air temp I would assume 6350-6450 norm depending on sea level and weather. Oh also BMI will affect rpm more than weather. Lol.

    Pop a dome out - so we can see side and top If it’s the traditional greater dome same as about 15 other billet heads. Protec still sells them. Cool, protec, Blowsion, JSU, kommander, watcon,UMI,speedwerx,east coast, Rius and a few others use same dome. note: NOT Riva or ADA
