mines the nickle based one which seems to cope with most things i use it on :cool4:.
where the headers sit in the ports is actually cooler than the down pipes and you will probably be ok with the copper based but if you can afford it get the nickle one :thumbup1:.

Guzzi lovers
 

Me too, I'm firmly and happily stuck in the 'round barrel rut' of pre-81 Guzzis - I just got back from the Colombres Rally in the Picos: rode back up through France on my '77 Mk 1 Le Mans and it didn't miss a beat, though my Dad (76 years old) managed to park his '81 G5 Spada lookalike in a ditch near Alencon. He was fine apart from concussion and burns, but his bike's now yet another project on my bench!

I'd never come across nickel-based grease - will get some. Hope it's not as expensive as some anti-electrolytic grease I bought a few years back - about 8 quid for a small toothpaste sized tube as I recall.

its very expensive £40 for a tin these days i'm affraid :thumbdown:
but i did spot some 1000 MOLYKOTE ANTI-SEIZE thread paste for £5 a tube and that stuffs rated to 650°C :thumbup1:

Never seize
 

Hi black dog,
never seize, and all these type of products will easily take the Temps generated by exhaust. I've used them on steam, and high temp hot oil rigs for years with no problems.:thumbup1:

Thanks Chucky!
