Sealing oem carb holder to reed block
I have plans to switch back to the stock reed cage as the Lectron will not work with the thicker v force reed block. I had an issue in the past with the carb holder not sealing fully to the reed block. I see that the built in o rings on the carb holder are what create the seal. I am wondering what the best solution is to be absolutely sure the reed block seals the first time around. Thanks

I always use the factory gasket.
If you lend someone $20, and never see that person again, it was probably worth it.

Hey, I’m talking about the area the carb holder and reed block that technically uses no gasket. Thanks and happy holidays

Put a very thin coat of grease on the seal lip it will allow the boot to kinda slide around a bit and help everything line up.

Re: Sealing oem carb holder to reed block
I went through this before too, if the o rings are damaged or flattened there is no way of sealing it, you can't just cut a gasket as the seal also holds the white plastic insert into the reed block, I tried many different combinations but in the end I bought a new carb boot, if you are able do a leak down test and spray around the carb boot to check for no leaks, I also have a lectron

Re: Sealing oem carb holder to reed block
Thanks. I had a thought. Maybe I can just run a small bead of rtv around the outer o ring. The one that’s closes to the edges or the carb boot.kdxdazz wrote: ↑07:57 pm Nov 29 2022 I went through this before too, if the o rings are damaged or flattened there is no way of sealing it, you can't just cut a gasket as the seal also holds the white plastic insert into the reed block, I tried many different combinations but in the end I bought a new carb boot, if you are able do a leak down test and spray around the carb boot to check for no leaks, I also have a lectron

Tolerant to oil not gasoline, threebond 1104 and 1211 is tolerant to gasoline

Re: Sealing oem carb holder to reed block
So do you think it will be safe to use one of those on the carb holder to reeds surfaces? I was thinking i should only use it on the out side o ring that is built in to the carb holder.

Re: Sealing oem carb holder to reed block
Yes, either one of those will work, 1104 fills gaps better 1211 is easier to remove, just remember to wipe everything down with thinners 10 times so it can bond

Re: Sealing oem carb holder to reed block
Ok having a hard time finding 1104 in the US. Not sure what a good alternative would be here. Maybe Permatex moto seal or Hondabond 4.kdxdazz wrote: ↑03:42 am Dec 19 2022Yes, either one of those will work, 1104 fills gaps better 1211 is easier to remove, just remember to wipe everything down with thinners 10 times so it can bond
