This is not SOHC related but still has a Honda theme! Actually it’s a request for my 1999 VF800fi so four cams and not one
I’ve been having problems with the rear tire losing up to 10psi over 3 or 4 days. I originally put this down to a slow puncture/leaky valve but after changing the tire twice and four new valves later it is still doing it. I have tried everything from using a green anti puncture gloop in the tire to using rim sealer and nothing works. The tire fitter is sure the rim is porous as he has seen this before and especially with Chinese cast bike wheels. I bought the bike with the ‘slow puncture’ four years ago and have lived with it but now it’s become a pia when I use it for trips away.
I have bought a s/h VFR wheel from ebay, it has its original paint and is in excellent condition. The tire fitter has advised I seal the inner rim with anti-porous paint before fitting the tire and new valve just in case this wheel has the same issue.
Can anyone recommend a suitable anti-porous paint, all I can find is garage floor paint and I really don’t need 2.5 litres of the stuff at £50!
I know 1960’s Royal Enfield’s had a problem with porous engine castings and they used to seal the inner halves with a special paint although that was a high temperature paint and I don’t know what that was called either
Any recommendations welcome otherwise I'll have to travel with my air compressor in tow!
