They seem to have two versions, one sold just as regulator for Buell and one 350kpa for Buell. But same part nr.

I hope they fixed the issue

Got this reply from the company that are responsible for Quantum products.

”Hello,

The regulator you were sent is 43 psi plus or minus three the original is 48 psi plus or minus three the psi levels over lap.
Thank you,

I removed my quantum fpr because stuff like that keeps me up at night. Potentially 40psi? I don’t think I could be ok with that. But like I said, I ran mine for 2 years no problems on a stock motor. The regulator I have now is 65 psi. Not a stock motor though.

I know that feeling, i cant get peace of mind for the smallest issue on my bikes. Crap like world politics and crises dont bother me a s hit in comparison.

Now i must change my intake seals before i can get a good nights sleep.

 

[Fredrikrosen]

I did change my intake seals today against James blue ones, after did i spray alot of starting spray on manifold but no change in rpm. How can i be sure it is 100% tight? Also, do i need to reset the TPS after change of seals?

 

[mike lowary]

If you have no change in rpms with spray then you did it correctly. The bolts need to be snug but remember they are not holding the bike together. As far as the tps reset, I don’t think it’s necessary as long as you didn’t remove the tps sensor from the throttle body. However, it’s such an easy task I would go ahead and reset it. Another one of those peace of mind things.

Shall the engine be hot or cold when making a TPS reset?

Repair manual says normal operating temp. So warm

Thanks!

So I am debating between Quantum and Revision Moto pump kits as they are complete compared to the Kemso one. The Kemso actually has a high psi range and is cheap but still need to buy regulator and O-rings separately.
