FUEL

Seafoam is an oil and fuel additive here in the US that cuts water and sludge in the crank case and fuel tank. it cleans the float bowls and jets in the carbs in the Magna. when I get garbage fuel at the local Stop & Rob here my Rocket starts sputtering I add a few shots and the steed will pep up. Plus the deceleration back fire is a nice blow flame. cool at night.
 
Yes, seafoam if used in excess will lean you out temporarily....a blow torch exhaust is not unexpected!
 
I run regular 89 regular. I've used See Foam with good results and just started adding a little Marvel Mystery oil because it's cheaper.
 
Can I ask what seafoam is? I use 500mls of methylated spirits if I think I have a bad batch of fuel

All internal combustion engines produce impurities that contain water and some type of crud. Seafoam is a strong engine cleaner that also works as dry gas. ALL modern engines can benefit from it's use.
 
There is no advantage running high test the Rocket will run better on regular and make more HP in the process
Correct, there is no advantage with running higher octane than specified in the owner's manual. The difference between lower and higher octanes are additives that prevent pre-detonation and slow burn process within the cylinder to prevent detonation (with no additional performance gains). If your engine makes say 150HP using regular, it will still only make 150HP on premium fuel or visa-versa. If however your high compression turbo bike pings on regular, not good, need higher octane. Now added detergents are a different story. Most major auto manufacturers have identified the top tier fuels to use. The top of the top tiers are Shell, Exon/Mobil, Amoco. Exon/Mobile has the highest detergent concentration in regular blend, followed by Shell then Amoco. Shell has the highest detergent blend in premium, followed by Exon/Mobil, then Amoco. If you avoid the no-name gas stations and use good quality top tier fuels, you should not need additional cleaners to keep your valves clean.
 
Similar to sea foam, a controlled spray / fine mist introduced in the intake will clean the pistons, runners, valve faces and exhaust ports.

Most people are terrified of doing it though, and for good reason lol.

Water injection has grown though as a cooling agent in extremely high boost detonation prone motors (4g63 etc at 30+ psi).
 
I plan on making that part of my maintenance routine. 50/50 water/Seafoam in a spray bottle misting one cylinder at a time while it runs.
